New AGA CPU focuses on gastric peroral endoscopic myotomy for gastroparesis
Authored by Mouen A. Khashab, MD, director of therapeutic endoscopy at Johns Hopkins Medicine, Baltimore; Andrew Y. Wang, MD, AGAF, chief of interventional endoscopy, University of Virginia, Charlottesville; and, Qiang Cai, MD, PhD, chief of gastroenterology, Ochsner LSU Health Shreveport (La.), the update covers patient selection, procedural considerations, adverse events (AEs), and other topics.
“G-POEM is being performed worldwide to treat patients with refractory gastroparesis,” the investigators wrote in Gastroenterology). “G-POEM is an overall safe procedure with high technical success rates, particularly when performed by an endoscopist experienced in third-space endoscopy. Even if the durable clinical success of G-POEM is in the 50% to 60% range, this represents a huge clinical benefit to patients with refractory gastroparesis, which is a disease associated with substantial morbidity, poor quality of life, and a paucity of safe and effective treatments.”
The authors listed treatment alternatives, noting how associated clinical data have fallen short.
“Although endoscopic pyloric balloon dilation, intrapyloric botulinum toxin injection, gastric electrical stimulation, and transpyloric stenting have been used in patients [with gastroparesis] who have not responded to medical therapy, published studies concerning these therapies have been inconsistent, shown no benefit, or lacked methodologic rigor,” they wrote.
Patient selection
G-POEM should be considered in patients with medically refractory gastroparesis due to diabetes, prior surgery, or idiopathic causes. Candidates should undergo endoscopy to confirm no mechanical obstruction, as well as a solid-phase gastric emptying scan to confirm delayed emptying, with ideal candidates showing at least 20% retention at 4 hours, as this threshold has been linked with better clinical outcomes.
G-POEM is most beneficial when moderate to severe symptoms are present, the investigators wrote, particularly vomiting and nausea. The Gastroparesis Cardinal Symptom Index (GCSI) can be used to determine severity, with a score greater than 2 indicating moderate to severe presentation.
Procedural considerations
The CPU offers detailed procedural considerations, including preparation and equipment, technical guidance, and postprocedural strategy.
“G-POEM should only be performed by interventional endoscopists with expertise or training in third-space endoscopy,” Dr. Khashab and colleagues wrote. “Although experience in endoscopic submucosal dissection (ESD) is not mandatory before performing G-POEM, it likely shortens the learning curve.”
Equipment minimums are also described, including “a high-definition gastroscope, with a waterjet, affixed with a clear distal cap” and “a modern electrosurgical generator capable of modulating power based on tissue resistance and circuit impedance.”
While G-POEM is typically performed via a greater-curvature approach, similar outcomes have been documented for a lesser-curvature approach, Dr. Khashab and colleagues wrote. This alternative technique may increase difficulty of pyloromyotomy, they added.
Postprocedural care may involve an overnight stay, according to the update, with an upper GI study on the subsequent day to ensure no contrast leakage, though this is not mandatory.
Adverse events
“G-POEM is generally safe when performed by trained and/or experienced endoscopists, and AEs are uncommon,” the investigators wrote. “However, serious AEs can occur and have been reported.”
Reported AEs include capnoperitoneum, inadvertent mucosotomy, thermal-mucosal injury, abdominal pain, bleeding, gastric ulceration, and dumping syndrome.
Insurance companies called to action
After reviewing emerging data, the authors suggested the time has come to consider G-POEM as a routine, evidence-based procedure that deserves appropriate reimbursement by financial stakeholders.
“Many insurers still consider G-POEM investigational and refuse to cover this procedure for patients with medically refractory gastroparesis,” they wrote. “As the safety and clinical effectiveness of G-POEM is now well supported, insurance companies and payors should cover G-POEM for patients with significant gastroparesis.”
The clinical practice update was commissioned and approved by the American Gastroenterological Association. The investigators disclosed relationships with Boston Scientific, Medtronic, and Olympus, among others.

Mucosal exposure device boosts AI-assisted detection of adenomas
based on results of a randomized trial.
Using the mucosal exposure device increased adenoma detection rate by 12% without impacting safety or withdrawal time, suggesting that the two approaches have a synergistic effect, reported lead author Marco Spadaccini, MD, of Humanitas University, Pieve Emanuele, Italy, and colleagues.
“Recent advances in AI, deep learning, and computer vision led to implementation of computer-aided detection [CADe] of colorectal polyps,” the investigators wrote in Gastroenterology. “CADe-assisted colonoscopy already proved its efficacy by increasing adenoma detection in randomized parallel and crossover trials. However, such benefit is mostly related to the higher accuracy in spotting lesions already within the visual field, not affecting the amount of mucosa exposed by the endoscopist during the scope withdrawal. Increasing the mucosa exposure represents a complementary strategy to CADe in order to further improve detection of colorectal neoplasia.”
To test their hypothesis, the investigators conducted a randomized trial involving 1,316 subjects undergoing routine colonoscopy at six centers in Italy and Switzerland. Participants were randomized in a 1:1 ratio to undergo colonoscopy with CADe (GI Genius, Medtronic) or CADe plus a mucosal exposure device (Endocuff Vision, Olympus).
The combination approach yielded a 49.6% adenoma detection rate, compared with a 44.0% detection rate for CADe alone (relative risk, 1.12; 95% confidence interval, 1.00-1.26; P = .04). Adding the mucosal exposure device was also associated with a higher number of adenomas detected per colonoscopy. Withdrawal time and rate of unnecessary polypectomies did not differ between groups.
“The benefit of adding [the mucosal exposure device] to AI was expected due to the complementary nature of the interventions,” Dr. Spadaccini and colleagues wrote. “The benefit of [the mucosal exposure device] is limited to increase the quantity of mucosa exposed to the lens by flatting the folds and strengthening the angulations, and the benefit of AI is only in spotting a lesion that is already displayed within the field of view. Thus, we may speculate that the additional mucosal exposure was synergistic to the AI-assisted polyp recognition by AI.”
The benefits of a combination approach were not universal, however, as the mucosal exposure device did not improve detection of either serrated lesions or advanced adenomas. This result was anticipated, the investigators noted, since the miss rate for diminutive or proximal adenomas is higher than it is for larger or distal lesions, and previous research has suggested that AI-assisted and mucosal exposure techniques, when used alone, are most effective for detecting smaller, proximal lesions.
The study was funded by a European Society of Gastrointestinal Endoscopy Artificial Intelligence Award. The investigators disclosed additional relationships with Fujifilm, Medtronic, Olympus, and others.
The paradigm of adenoma detection is rapidly shifting within the context of screening-related colonoscopy. If one considers the various interventions available to improve one’s adenoma detection rate (ADR), the landscape is vastly different than it was 5-10 years ago. Two established interventions with robust supporting data from randomized controlled trials (RCTs) are computer-aided detection (CADe) platforms such as GI Genius (Medtronic) and distal attachment devices such as Endocuff Vision (Olympus). This RCT by Spadaccini and colleagues tested the intuitive hypothesis that these interventions applied together boost ADR, compared with CADe alone.
Real-world studies of CADe’s effectiveness on ADR are less impressive than efficacy data from trials. Whereas CADe platforms require a significant one-time investment, distal attachment devices represent a small fraction of single procedural costs which then incrementally add up when used over large volumes. More head-to-head studies, cost-effectiveness analyses, and real-world studies are needed to elucidate the best single and/or combination strategies for optimizing ADR. In the meantime, endoscopists should be aware of all evidence-based techniques for ADR improvement, including those that can be incorporated at little to no cost.

Tips for addressing uptick in mental health visits: Primary care providers collaborate, innovate
This growth in the number of patients needing behavioral health–related care is likely driven by multiple factors, including a shortage of mental health care providers, an increasing incidence of psychiatric illness, and destigmatization of mental health in general, suggested Swetha P. Iruku, MD, MPH, associate professor of family medicine and community health at the University of Pennsylvania and Penn Medicine family physician in Philadelphia.
The Centers for Disease Control and Prevention noted that “the COVID-19 pandemic has been associated with mental health challenges related to the morbidity and mortality caused by the disease and to mitigation activities, including the impact of physical distancing and stay-at-home orders,” in a Morbidity and Mortality Weekly Report.
From June 24 to 30, 2020, U.S. adults reported considerably elevated adverse mental health conditions associated with COVID-19, and symptoms of anxiety disorder and depressive disorder climbed during the months of April through June of the same year, compared with the same period in 2019, they wrote.
Even before the pandemic got underway, multiple studies of national data published this year suggested mental issues were on the rise in the United States. For example, the proportion of adult patient visits to primary care providers that addressed mental health concerns rose from 10.7% to 15.9% from 2006 to 2018, according to research published in Health Affairs. Plus, the number and proportion of pediatric acute care hospitalizations because of mental health diagnoses increased significantly between 2009 and 2019, according to a paper published in JAMA.
“I truly believe that we can’t, as primary care physicians, take care of someone’s physical health without also taking care of their mental health,” Dr. Iruku said in an interview. “It’s all intertwined.”
To rise to this challenge, PCPs first need a collaborative mindset, she suggested, as well as familiarity with available resources, both locally and virtually.
This article examines strategies for managing mental illness in primary care, outlines clinical resources, and reviews related educational opportunities.
In addition, clinical pearls are shared by Dr. Iruku and five other clinicians who provide or have provided mental health care to primary care patients or work in close collaboration with a primary care practice, including a clinical psychologist, a nurse practitioner licensed in psychiatric health, a pediatrician, and a licensed clinical social worker.
Build a network
Most of the providers interviewed cited the importance of collaboration in mental health care, particularly for complex cases.
“I would recommend [that primary care providers get] to know the psychiatric providers [in their area],” said Jessica Viton, DNP, FNP, PMHNP, who delivers mental health care through a community-based primary care practice in Colorado which she requested remain anonymous.
Dr. Iruku suggested making an in-person connection first, if possible.
“So much of what we do is ‘see one, do one, teach one,’ so learn a little bit, then go off and trial,” she said. “[It can be valuable] having someone in your back pocket that you can contact in the case of an emergency, or in a situation where you just don’t know how to tackle it.”
Screen for depression and anxiety
William J. Sieber, PhD, a clinical psychologist, director of integrated behavioral health, and professor in the department of family medicine and public health and the department of psychiatry at the University of California, San Diego, said primary care providers should screen all adult patients for depression and anxiety with the Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder Assessment (GAD-7), respectively.
To save time, he suggested a cascading approach.
“In primary care, everybody’s in a hurry,” Dr. Sieber said. “[With the cascading approach,] the first two items [from each questionnaire] are given, and if a person endorses either of those items … then they are asked to complete the other items.”
Jennifer Mullally, MD, a pediatrician at Sanford Health in Fargo, N.D., uses this cascading approach to depression and anxiety screening with all her patients aged 13-18. For younger kids, she screens only those who present with signs or symptoms of mental health issues, or if the parent shares a concern.
This approach differs slightly from U.S. Preventive Services Task Force recommendations, which suggest screening for anxiety in patients aged 8-18 years and depression in patients aged 12-18 years.
Use other screening tools only as needed
Dr. Sieber, the research director for the division of family medicine at UC San Diego, collaborates regularly with primary care providers via hallway consultations, by sharing cases, and through providing oversight of psychiatric care at 13 primary care practices within the UC San Diego network. He recommended against routine screening beyond depression and anxiety in the primary care setting.
“There are a lot of screening tools,” Dr. Sieber said. “It depends on what you’re presented with. The challenge in primary care is you’re going to see all kinds of things. It’s not like running a depression clinic.”
Other than the PHQ-9 and GAD-7, he suggested primary care providers establish familiarity with screening tools for posttraumatic stress disorder and attention-deficit/hyperactivity disorder, noting again that these should be used only when one of the conditions is already suspected.
Dr. Mullally follows a similar approach with her pediatric population. In addition to the GAD-7, she investigates whether a patient has anxiety with the Screen for Child Anxiety Related Disorders (SCARED). For depression, she couples the PHQ-9 with the Columbia Suicide Severity Rating Scale.
While additional screening tools like these are readily available online, Dr. Viton suggested that they should be employed only if the provider is trained to interpret and respond to those findings, and only if they know which tool to use, and when.
For example, she has recently observed PCPs diagnosing adults with ADHD using a three-question test, when in fact a full-length, standardized instrument should be administered by a provider with necessary training.
She also pointed out that bipolar disorder continues to be underdiagnosed, possibly because of providers detecting depression using a questionnaire like the PHQ-9, while failing to inquire about manic episodes.
Leverage online resources
If depression is confirmed, Dr. Iruku often directs the patient to the Mayo Clinic Depression Medication Choice Decision Aid. This website steers patients through medication options based on their answers to a questionnaire. Choices are listed alongside possible adverse effects.
For clinician use, Dr. Iruku recommended The Waco Guide to Psychopharmacology in Primary Care, which aids clinical decision-making for mental illness and substance abuse. The app processes case details to suggest first-, second-, and third-line pharmacotherapies, as well as modifications based on patient needs.
Even with tools like these, however, a referral may be needed.
“[Primary care providers] may not be the best fit for what the patient is looking for, from a mental health or behavioral standpoint,” Dr. Sieber said.
In this case, he encourages patients to visit Psychology Today, a “quite popular portal” that helps patients locate a suitable provider based on location, insurance, driving radius, and mental health concern. This usually generates 10-20 options, Dr. Sieber said, although results can vary.
“It may be discouraging, because maybe only three [providers] pop up based on your criteria, and the closest one is miles away,” he said.
Consider virtual support
If no local psychiatric help is available, Dr. Sieber suggested virtual support, highlighting that “it’s much easier now than it was 3 or 4 years ago” to connect patients with external mental health care.
But this strategy should be reserved for cases of actual need instead of pure convenience, cautioned Dr. Viton, who noted that virtual visits may fail to capture the nuance of an in-person meeting, as body language, mode of dress, and other clues can provide insights into mental health status.
“Occasionally, I think you do have to have an in-person visit, especially when you’re developing a rapport with someone,” Dr. Viton said.
Claire McArdle, a licensed clinical social worker in Fort Collins, Colo., noted that virtual care from an outside provider may also impede the collaboration needed to effectively address mental illness.
In her 11 years in primary care at Associates in Family Medicine, Ms. McArdle had countless interactions with colleagues seeking support when managing a complex case. “I’m coaching providers, front desk staff, and nursing staff on how to interact with patients [with] behavioral health needs,” she said, citing the multitude of nonmedical factors that need to be considered, such as family relationships and patient preferences.
These unscheduled conversations with colleagues throughout the day are impossible to have when sharing a case with an unknown, remote peer.
Ms. McArdle speaks from experience. She recently resigned from Associates in Family Medicine to start her own private therapy practice after her former employer was acquired by VillageMD, a national provider that terminated employment of most other social workers in the practice and began outsourcing mental health care to Mindoula Health, a virtual provider.
Dr. Sieber offered a similar perspective on in-person collaboration as the psychiatric specialist at his center. He routinely offers on-site support for both providers and patients, serving as “another set of eyes and ears” when there is a concern about patient safety or directly managing care when a patient is hospitalized for mental illness.
While virtual solutions may fall short of in-person management, they can offer care at a scale and cost impossible through traditional practice.
This could even be free. Zero-cost, automated software now allows individuals who are uninsured or unable to afford care at least one avenue to manage their mental health concerns.
For example, Bliss is a free, 8-session, interactive online therapy program for depression that was created by the Centre for Interactive Mental Health Solutions. The program offers a tool for monitoring mood and quizzes to test understanding of personal mental health management, among other features.
More advanced programs are emerging as artificial intelligence (AI) enables dialogues between humans and machines. This is the case with Woebot, an app that asks the user about their mood throughout the day, and responds with evidence-based strategies for managing concerns, all for free at press time.
Keep learning
A range of educational options and professional resources are available for primary care providers who would like to improve their knowledge of mental health care. These include formal fellowships in primary care psychiatry/behavioral health integration, free mental health webinars, and various other opportunities.
Eric Eschweiler, DNP, APRN, FNP-C, PHN, completed the University of California, Irvine, Train New Trainers (TNT) Primary Care Psychiatry (PCP) Fellowship in 2016, when he was working as a solo nurse practitioner.
“I was drowning in practice,” said Dr. Eschweiler, director of nursing and public health outreach services at Riverside-San Bernardino County Indian Health, Grand Terrace, Calif., in an interview. “I was a solo NP. There was no physician on site. We were seeing a lot of [individuals with] schizoaffective [disorder] in downtown San Bernardino, the homeless, unhoused – a lot of substance use. I felt I needed to have the skills to be able to treat them effectively. That’s what the fellowship did.”
The skills Dr. Eschweiler learned from participating in his fellowship allowed him to manage more cases of mental illness without need for referral. When a referral was needed for a complex or severe case, he had the confidence to bridge care and collaborate more effectively with psychiatric specialists.
“It was awesome, because we were able to communicate using the same language,” Dr. Eschweiler said of these collaborations. “It’s [about] talking that same language, starting those initial treatments, and then moving forward with specialty care, and vice versa. [Psychiatric specialists] would send me patients that needed medical care because of the types of medications they were taking. And I was then very well aware of those side effects and other issues that might come up from those treatments. So it’s a two-way street.”
Dr. Eschweiler was so impressed by his fellowship that he has since ushered multiple providers through the program since transitioning to an administrative role as director of nursing.
In Fargo, where psychiatric care is sparse and wait times for referral can be months long, Dr. Mullally, like Dr. Eschweiler, knew that she needed more training in mental health.
“I don’t feel like we get enough training in residency,” Dr. Mullally said. “So you do need to look at your options for further CME.”
Out of several CME courses she has taken to further her understanding of pediatric psychiatry, Dr. Mullally recommended The Reach Institute above all others, as their courses involve in-depth discussions and valuable handouts, particularly for medication selection.
“I think that a lot of the other CMEs tend to involve a lot more PowerPoint presentations,” Dr. Mullally said. “And you don’t necessarily leave with a lot of good documents. I still use my Reach handouts. I have them sitting right next to me. I use them every single day.”
Providers interested in The Reach Institute, however, should be prepared to invest both time and money, she added, citing a 2-3 day commitment, and calling it “not cheap.” To overcome these barriers, she suggested that providers get their institution to support their attendance.
For a lighter commitment, Dr. Iruku recommended the American Academy of Family Physicians CME portal, as this offers 13 online, accredited courses covering a range of topics, from adolescent health to substance abuse disorders.
Dr. Sieber suggested that primary care providers join the Collaborative Family Healthcare Association, which aims to integrate physical and behavioral health in routine practice. CFHA, of which he is a member, offers a “bevy of different resources” for interested providers, including a conference in Phoenix this October.
The interviewees disclosed no conflicts of interest.
This growth in the number of patients needing behavioral health–related care is likely driven by multiple factors, including a shortage of mental health care providers, an increasing incidence of psychiatric illness, and destigmatization of mental health in general, suggested Swetha P. Iruku, MD, MPH, associate professor of family medicine and community health at the University of Pennsylvania and Penn Medicine family physician in Philadelphia.
The Centers for Disease Control and Prevention noted that “the COVID-19 pandemic has been associated with mental health challenges related to the morbidity and mortality caused by the disease and to mitigation activities, including the impact of physical distancing and stay-at-home orders,” in a Morbidity and Mortality Weekly Report.
From June 24 to 30, 2020, U.S. adults reported considerably elevated adverse mental health conditions associated with COVID-19, and symptoms of anxiety disorder and depressive disorder climbed during the months of April through June of the same year, compared with the same period in 2019, they wrote.
Even before the pandemic got underway, multiple studies of national data published this year suggested mental issues were on the rise in the United States. For example, the proportion of adult patient visits to primary care providers that addressed mental health concerns rose from 10.7% to 15.9% from 2006 to 2018, according to research published in Health Affairs. Plus, the number and proportion of pediatric acute care hospitalizations because of mental health diagnoses increased significantly between 2009 and 2019, according to a paper published in JAMA.
“I truly believe that we can’t, as primary care physicians, take care of someone’s physical health without also taking care of their mental health,” Dr. Iruku said in an interview. “It’s all intertwined.”
To rise to this challenge, PCPs first need a collaborative mindset, she suggested, as well as familiarity with available resources, both locally and virtually.
This article examines strategies for managing mental illness in primary care, outlines clinical resources, and reviews related educational opportunities.
In addition, clinical pearls are shared by Dr. Iruku and five other clinicians who provide or have provided mental health care to primary care patients or work in close collaboration with a primary care practice, including a clinical psychologist, a nurse practitioner licensed in psychiatric health, a pediatrician, and a licensed clinical social worker.
Build a network
Most of the providers interviewed cited the importance of collaboration in mental health care, particularly for complex cases.
“I would recommend [that primary care providers get] to know the psychiatric providers [in their area],” said Jessica Viton, DNP, FNP, PMHNP, who delivers mental health care through a community-based primary care practice in Colorado which she requested remain anonymous.
Dr. Iruku suggested making an in-person connection first, if possible.
“So much of what we do is ‘see one, do one, teach one,’ so learn a little bit, then go off and trial,” she said. “[It can be valuable] having someone in your back pocket that you can contact in the case of an emergency, or in a situation where you just don’t know how to tackle it.”
Screen for depression and anxiety
William J. Sieber, PhD, a clinical psychologist, director of integrated behavioral health, and professor in the department of family medicine and public health and the department of psychiatry at the University of California, San Diego, said primary care providers should screen all adult patients for depression and anxiety with the Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder Assessment (GAD-7), respectively.
To save time, he suggested a cascading approach.
“In primary care, everybody’s in a hurry,” Dr. Sieber said. “[With the cascading approach,] the first two items [from each questionnaire] are given, and if a person endorses either of those items … then they are asked to complete the other items.”
Jennifer Mullally, MD, a pediatrician at Sanford Health in Fargo, N.D., uses this cascading approach to depression and anxiety screening with all her patients aged 13-18. For younger kids, she screens only those who present with signs or symptoms of mental health issues, or if the parent shares a concern.
This approach differs slightly from U.S. Preventive Services Task Force recommendations, which suggest screening for anxiety in patients aged 8-18 years and depression in patients aged 12-18 years.
Use other screening tools only as needed
Dr. Sieber, the research director for the division of family medicine at UC San Diego, collaborates regularly with primary care providers via hallway consultations, by sharing cases, and through providing oversight of psychiatric care at 13 primary care practices within the UC San Diego network. He recommended against routine screening beyond depression and anxiety in the primary care setting.
“There are a lot of screening tools,” Dr. Sieber said. “It depends on what you’re presented with. The challenge in primary care is you’re going to see all kinds of things. It’s not like running a depression clinic.”
Other than the PHQ-9 and GAD-7, he suggested primary care providers establish familiarity with screening tools for posttraumatic stress disorder and attention-deficit/hyperactivity disorder, noting again that these should be used only when one of the conditions is already suspected.
Dr. Mullally follows a similar approach with her pediatric population. In addition to the GAD-7, she investigates whether a patient has anxiety with the Screen for Child Anxiety Related Disorders (SCARED). For depression, she couples the PHQ-9 with the Columbia Suicide Severity Rating Scale.
While additional screening tools like these are readily available online, Dr. Viton suggested that they should be employed only if the provider is trained to interpret and respond to those findings, and only if they know which tool to use, and when.
For example, she has recently observed PCPs diagnosing adults with ADHD using a three-question test, when in fact a full-length, standardized instrument should be administered by a provider with necessary training.
She also pointed out that bipolar disorder continues to be underdiagnosed, possibly because of providers detecting depression using a questionnaire like the PHQ-9, while failing to inquire about manic episodes.
Leverage online resources
If depression is confirmed, Dr. Iruku often directs the patient to the Mayo Clinic Depression Medication Choice Decision Aid. This website steers patients through medication options based on their answers to a questionnaire. Choices are listed alongside possible adverse effects.
For clinician use, Dr. Iruku recommended The Waco Guide to Psychopharmacology in Primary Care, which aids clinical decision-making for mental illness and substance abuse. The app processes case details to suggest first-, second-, and third-line pharmacotherapies, as well as modifications based on patient needs.
Even with tools like these, however, a referral may be needed.
“[Primary care providers] may not be the best fit for what the patient is looking for, from a mental health or behavioral standpoint,” Dr. Sieber said.
In this case, he encourages patients to visit Psychology Today, a “quite popular portal” that helps patients locate a suitable provider based on location, insurance, driving radius, and mental health concern. This usually generates 10-20 options, Dr. Sieber said, although results can vary.
“It may be discouraging, because maybe only three [providers] pop up based on your criteria, and the closest one is miles away,” he said.
Consider virtual support
If no local psychiatric help is available, Dr. Sieber suggested virtual support, highlighting that “it’s much easier now than it was 3 or 4 years ago” to connect patients with external mental health care.
But this strategy should be reserved for cases of actual need instead of pure convenience, cautioned Dr. Viton, who noted that virtual visits may fail to capture the nuance of an in-person meeting, as body language, mode of dress, and other clues can provide insights into mental health status.
“Occasionally, I think you do have to have an in-person visit, especially when you’re developing a rapport with someone,” Dr. Viton said.
Claire McArdle, a licensed clinical social worker in Fort Collins, Colo., noted that virtual care from an outside provider may also impede the collaboration needed to effectively address mental illness.
In her 11 years in primary care at Associates in Family Medicine, Ms. McArdle had countless interactions with colleagues seeking support when managing a complex case. “I’m coaching providers, front desk staff, and nursing staff on how to interact with patients [with] behavioral health needs,” she said, citing the multitude of nonmedical factors that need to be considered, such as family relationships and patient preferences.
These unscheduled conversations with colleagues throughout the day are impossible to have when sharing a case with an unknown, remote peer.
Ms. McArdle speaks from experience. She recently resigned from Associates in Family Medicine to start her own private therapy practice after her former employer was acquired by VillageMD, a national provider that terminated employment of most other social workers in the practice and began outsourcing mental health care to Mindoula Health, a virtual provider.
Dr. Sieber offered a similar perspective on in-person collaboration as the psychiatric specialist at his center. He routinely offers on-site support for both providers and patients, serving as “another set of eyes and ears” when there is a concern about patient safety or directly managing care when a patient is hospitalized for mental illness.
While virtual solutions may fall short of in-person management, they can offer care at a scale and cost impossible through traditional practice.
This could even be free. Zero-cost, automated software now allows individuals who are uninsured or unable to afford care at least one avenue to manage their mental health concerns.
For example, Bliss is a free, 8-session, interactive online therapy program for depression that was created by the Centre for Interactive Mental Health Solutions. The program offers a tool for monitoring mood and quizzes to test understanding of personal mental health management, among other features.
More advanced programs are emerging as artificial intelligence (AI) enables dialogues between humans and machines. This is the case with Woebot, an app that asks the user about their mood throughout the day, and responds with evidence-based strategies for managing concerns, all for free at press time.

Study explains link between fatty liver and CRC liver metastasis
according to the authors of new research.
These findings support the previously reported link between fatty liver and colorectal cancer (CRC) liver metastasis, and suggest that CRC patients with nonalcoholic fatty liver disease (NAFLD) may respond differently to treatment than CRC patients without NAFLD, wrote lead author Zhijun Wang, MD, PhD, of Cedars-Sinai Medical Center, Los Angeles, and colleagues, in their paper.
“Obesity and NAFLD are the significant risk factors for CRC,” the investigators explained, in Cell Metabolism. “A growing body of epidemiological evidence indicates that fatty liver increases the occurrence of CRC liver metastasis and the local recurrence after resection of CRC liver metastases, thereby worsening prognosis ... There is an urgent need to understand the molecular mechanisms of metastasis in patients with fatty liver to manage those patients effectively.”
To this end, Dr. Wang and colleagues conducted a series of experiments involving mice, cell cultures, and human sera. They found that fatty liver increases risk of CRC liver metastasis via extracellular vesicles (EVs) that contain procarcinogenic miRNAs. As these EVs transfer microRNAs from fatty liver hepatocytes to metastatic cancer cells, YAP activity increases, which, in turn, suppresses immune activity within the tumor microenvironment, promoting growth of CRC metastasis.
Beyond the increased risk of liver metastasis presented by fatty liver, the investigators suggested that NAFLD may cause “more complex” metastatic tumor microenvironments, potentially explaining “diverse responses” to cancer therapies among patients with CRC and liver metastases.
“In summary, our study demonstrates that the pre- and prometastatic liver environment of fatty liver is induced by procarcinogenic EVs and results in an immunosuppressive tumor microenvironemnt, in which YAP plays an important role,” the investigators concluded. “Our study provides new insight into [the] distinct liver tumor microenvironment in patients with fatty liver and without fatty liver, which may contribute to the aggressiveness of metastatic tumors and weak responses to anticancer therapy in patients with fatty liver. Additional studies are warranted to develop precision medicine for treating patients with CRC and liver metastasis.”
One of the study authors disclosed relationships with Altimmune, Cytodyn, Novo Nordisk, and others. The other investigators had no relevant financial disclosures.

Incidence rates were higher for cohorts that underwent HCC surveillance versus those that did not undergo surveillance, suggesting that such programs offer significant benefit, lead author Daniel Q. Huang, MBBS, of the University of California, San Diego, and colleagues reported.
“A systematic review of the incidence of HCC among patients with alcohol-associated cirrhosis has not been reported,” the investigators wrote in Clinical Gastroenterology and Hepatology, prompting the present research.
Previous studies have described a broad range of annual incidence findings for HCC in this population, from 0.6% to 5.6%, suggesting that a systematic approach was needed.
To this end, Dr. Huang and colleagues analyzed data from 18 studies that involved 148,333 patients with alcohol-associated cirrhosis. The primary analysis aimed to determine cumulative incidence rates over time, while the secondary analysis characterized the impact of participation in HCC surveillance programs.
“This meta-analysis used reconstructed individual participant data, which is considered to be the gold standard for reporting survival data because it accounts for censoring of events,” the investigators noted. “The current study provides important data that are useful for clinical practice and clinical trial design.”
The cumulative incidence rates of HCC were 1%, 3%, and 9% at 1 year, 5 years, and 10 years, respectively. Among 12 of the risk factors studied, smoking, diabetes, and decompensation were all significantly associated with rate of HCC.
“Therefore, patients with alcohol-associated cirrhosis should be screened for diabetes to identify the patients at high risk for HCC development,” the investigators wrote. “In addition, patients with alcohol-associated cirrhosis should be advised to stop smoking, while patients with hepatic decompensation should be monitored carefully for the development of HCC if clinically appropriate.”
The secondary analysis showed that HCC incidence rates were higher among patients participating in HCC surveillance programs than those who did not participate (18.6 vs. 4.8 per 1,000 person-years; P = .001).
“Patients with alcohol-associated cirrhosis are known to have lower HCC surveillance rates, which may be related to poor disease awareness, clinic time constraints caused by other active medical issues, and provider beliefs regarding the likelihood of adherence,” the investigators noted.
Increased efforts are needed to promote surveillance in this population, they added, suggesting a range of communication pathways, including social media, traditional news outlets, and direct mailing.
Dr. Huang and colleagues also suggested that the findings should be validated in large prospective studies.
The study was funded by the National Institute on Alcohol Abuse and Alcoholism, the National Institute of Environmental Health Sciences, the National Center for Advancing Translational Sciences, and others. Dr. Huang disclosed funding from the Singapore Ministry of Health’s National Medical Research Council.
The association between cirrhosis and hepatocellular carcinoma (HCC) risk is well known and therefore routine surveillance is recommended by the American Association for the Study of Liver Diseases. More recent data has shown alcohol use to be an independent risk factor for HCC along with various other cancers.
Quite frequently, the focus of management in patients with alcohol-associated liver disease is alcohol cessation to prevent further decompensation, with screening often being overlooked. Previous studies have shown, however, that earlier detection is associated with improved survival. Another interesting finding of this study was that those patients who had concomitant smoking use, diabetes, and hepatic decompensation were more likely to develop HCC. When managing patients with alcohol related liver disease, confounding risk factors should be mitigated (that is, encouragement of smoking cessation, enhanced screening for diabetes, and more rigorous screening in decompensated patients).
This study brings to light the need for improved screening and concomitant risk factor mitigation for hepatocellular carcinoma given higher rates of detection in those undergoing surveillance. Larger, prospective studies are needed, however, to validate the findings in this study given the recent overall increase in rates of alcohol-associated liver disease.

Clinical Practice Update: Alpha-gal syndrome often causes GI issues without anaphylaxis, skin changes
according to an American Gastroenterological Association clinical practice update.
Although the allergic response is best known for a combination of anaphylaxis, skin changes, and gastrointestinal symptoms that occurs within hours of consuming mammalian-derived food products, health care providers should know that many patients experience gastrointestinal distress in the absence of other clinical signs, lead author Sarah K. McGill, MD, MSc, of the University of North Carolina at Chapel Hill, and colleagues reported.
“It is important for gastroenterologists to be aware of this condition and to be capable of diagnosing and treating it in a timely manner,” the investigators wrote in Clinical Gastroenterology and Hepatology.
To this end, Dr. McGill and colleagues drafted the present clinical practice update, covering pathogenesis, clinical manifestations, diagnosis, and management.
“The allergy in alpha-gal syndrome is to galactose alpha-1,3-galactose, an oligosaccharide on the cells of all nonprimate mammals,” the investigators wrote. “Surprisingly, sensitization to alpha-gal, that is, the process by which human beings develop IgE antibodies to the sugar, is understood to occur after the bite of a tick or parasitic infection. In the United States, the Lone Star tick, an ectoparasite whose principal host is deer, is strongly implicated.”
Gastrointestinal focused clinical research is scarce, the investigators noted, citing two observational studies involving 375 patients positive for alpha-gal IgE. Almost half of these patients (40.7%) had gastrointestinal symptoms alone. Across the entire population, the most common gastrointestinal symptoms were abdominal pain (71%) and vomiting (22%). About three out of four patients reported improvement on an alpha-gal avoidance diet.
“Clinicians should consider alpha-gal syndrome in the differential diagnosis of patients with unexplained gastrointestinal symptoms of abdominal pain, diarrhea, nausea, and vomiting, particularly those who live or have lived in an alpha-gal–prevalent area,” the investigators wrote.
In the United States, these areas span the domain of the Lone Star tick, including most of the East Coast, the central Midwest, the South, and all of Texas. Overseas, alpha-gal syndrome has been reported in Japan, Australia, Western Europe, and South Africa.
Clinical suspicion should be increased in patients with a history of tick bite, engagement in outdoor activities, and awakening in the night with gastrointestinal distress (because of the delay between allergen ingestion and symptom onset). Workup should include serum testing for alpha-gal IgE antibodies, according to the update. Serum positivity alone, however, is not sufficient for diagnosis. Alpha-gal syndrome must be confirmed by symptom resolution or improvement upon adherence to an alpha-gal avoidance diet for at least a month.
“During this time, patients may want to avoid eating at restaurants, which can easily cross-contaminate food, and processed food, which may contain alpha-gal in additives,” Dr. McGill and colleagues wrote.
Patients with alpha-gal syndrome who accidentally consume alpha-gal should take 25-50 mg of diphenhydramine and ensure access to a self-injectable epinephrine if symptoms progress, particularly if respiratory compromise occurs, they added.

AGA clinical practice update addresses role of endoscopic ultrasound–guided gallbladder drainage in acute cholecystitis
according to a recent clinical practice update by the American Gastroenterological Association.
The update, written by Shayan S. Irani, MD, of Virginia Mason Medical Center, Seattle, and colleagues, also covers techniques and outcomes of EUS-GBD and provides suggestions for training and patient selection.
“In this clinical practice update, we comment on the role of EUS-GBD (compared with ET-GBD [endoscopic treatment via transpapillary gallbladder drainage] and PT [percutaneous transhepatic]-GBD) in the management of acute cholecystitis, and describe its indications, contraindications, procedural considerations, and associated adverse events,” the authors wrote in Clinical Gastroenterology and Hepatology.
Dr. Irani and colleagues noted that EUS-GBD is a valuable alternative to PT-GBD, which can have a significant morbidity, and ET-GBD has been associated with relatively lower technical and clinical success rates in the presence of obstructing pathology of the cystic duct. Advances in lumen-apposing metal stents have further improved outcomes in EUS-GBD, as demonstrated by multiple case series and comparative trials.
According to the update, EUS-GBD is suggested in three scenarios: for draining the gallbladder in patients with acute cholecystitis who are at high risk for surgery, for removing percutaneous cholecystostomy drains in patients who cannot undergo cholecystectomy, and for draining malignant biliary obstruction in patients who have not responded to other treatments. EUS-GBD is contraindicated in patients with significant coagulopathy, large-volume uncontrolled ascites, or gallbladder perforation.
Dr. Irani and colleagues also noted that, between the three main techniques mentioned above, EUS-GBD has the lowest risk of recurrent cholecystitis, whereas ET-GBD and PT-GBD present slightly lower mortality rates.
While the update provides technical guidance on performing EUS-GBD, Dr. Irani and colleagues make clear that EUS-GBD is a highly specialized procedure that requires sufficient training to optimal results.
“Performing the procedure has an associated learning curve and requires advanced EUS training,” they wrote. “Two recent publications have suggested that the minimum number of procedures to gain competency should be approximately 19-25 procedures.”
Addressing unmet needs, Dr. Irani and colleagues suggested that more research is needed to standardize patient selection, procedure technique, and stent follow-up evaluation.
Ongoing studies aim to address whether endoscopic management of cholecystitis and symptomatic gallstones could become a mainstream treatment in the future, they wrote, but “we are still a long way from abandoning standard of care with cholecystectomy.”
This clinical practice update was commissioned by the AGA. Dr. Irani is a consultant for Boston Scientific, ConMed, and GORE; one coauthor received research support from Boston Scientific and Olympus and is a consultant and speaker for Boston Scientific, Cook, Medtronic, Olympus and ConMed.

PNPLA3 genotype predicts cirrhosis in NAFLD
while those with this genotype who also have diabetes and indeterminate Fibrosis-4 (FIB4) scores may have the same risk of cirrhosis as patients with a high FIB4, according to investigators.
These findings suggest that NAFLD patients with indeterminate FIB4 and metabolic risk factors should routinely undergo PNPLA3 genotyping, lead author Vincent L. Chen, MD, of the University of Michigan, Ann Arbor, and colleagues reported.
“Whether incorporating genetics into risk stratification results in meaningful improvement over clinical predictors, such as FIB4, diabetes, and obesity status, is unknown,” the investigators wrote in Gastroenterology. “Improved understanding of how genetics influences the rate of disease progression and how it interacts with established risk factors for advanced liver disease is crucial for genetic testing to be applicable in clinical practice.”
To evaluate the risk presented by the PNPLA3 p.I148M variant, Dr. Chen and colleagues analyzed data from two independent cohorts with 7,893 patients and 46,880 patients each.
They first characterized the relationship between PNPLA3 genotype and cirrhosis via univariable and multivariable analyses. These efforts revealed that the genotype predicted cirrhosis in both cohorts, with associations also detected for well-documented clinical risk factors, including diabetes, obesity, and high ALT. Of note, PNPLA3 genotype demonstrated an additive effect for cirrhosis when detected in conjunction with these risks.
Further analysis revealed that homozygous carriers of PNPLA3 p.I148M with indeterminate FIB4 scores (1.3-2.67) and diabetes had an incidence rate of cirrhosis on par with patients who had high-risk FIB4 (greater than 2.67).
The effects of the risk allele were also made evident by comparing patients with diabetes and indeterminate FIB4 based on presence or absence of the marker – those testing positive for h PNPLA3 p.I148M had 2.9-4.8 times greater risk of cirrhosis. Conversely, patients with FIB4 scores less than 1.3, regardless of other risk factors, had little change in cirrhosis rate regardless of PNPLA3 status.
“We found that PNPLA3 genotyping in conjunction with clinical risk factors may improve risk stratification in patients with NAFLD,” the investigators concluded. “Although it may be possible to develop more complex polygenic risk scores for cirrhosis, these findings suggest that genotyping of PNPLA3 alone, which is less expensive than genomewide genotyping and easier to understand, may have similar clinical applicability for NAFLD.”
Dr. Chen and colleagues therefore recommended that NAFLD patients with metabolic risk factors (particularly diabetes) and indeterminate FIB4 routinely undergo PNPLA3 genotyping, with referral to hepatology if positive for two risk alleles.
The study was supported by the American Association for the Study of Liver Diseases, National Institutes of Health, and the University of Michigan department of internal medicine. The investigators disclosed no conflicts of interest.
Nonalcoholic fatty liver disease (NAFLD) is becoming globally a leading cause of cirrhosis and related complications, namely decompensation and hepatocellular carcinoma. Since NAFLD affects a large fraction of the population, and especially people with obesity, type 2 diabetes and metabolic comorbidities, it is difficult to identify those at risk of cirrhosis and liver-related versus more frequent cardiometabolic events. The first step in risk stratification is based on the calculation of simple liver fibrosis scores, such as the FIB4, but this too often leads to indeterminate results requiring additional testing.
These results will contribute to establish referral pathways to identify persons at high risk of liver disease, even at a young age. This may enable preventive programs based on intensified lifestyle and diabetes management, specific treatments for fibrotic NAFLD once these become available, and close surveillance for complications. What’s more, therapeutic approaches directly targeting liver PNPLA3 p.I148M are already under clinical evaluation to prevent disease progression specifically in this high-risk group.

Luca Valenti, MD, is an associate professor of internal medicine in pathophysiology and transplantation at the Università degli Studi di Milano. He is head of the Precision Lab and Biological Resource Center Unit. Dr. Valenti has no relevant disclosures.
while those with this genotype who also have diabetes and indeterminate Fibrosis-4 (FIB4) scores may have the same risk of cirrhosis as patients with a high FIB4, according to investigators.
These findings suggest that NAFLD patients with indeterminate FIB4 and metabolic risk factors should routinely undergo PNPLA3 genotyping, lead author Vincent L. Chen, MD, of the University of Michigan, Ann Arbor, and colleagues reported.
“Whether incorporating genetics into risk stratification results in meaningful improvement over clinical predictors, such as FIB4, diabetes, and obesity status, is unknown,” the investigators wrote in Gastroenterology. “Improved understanding of how genetics influences the rate of disease progression and how it interacts with established risk factors for advanced liver disease is crucial for genetic testing to be applicable in clinical practice.”
To evaluate the risk presented by the PNPLA3 p.I148M variant, Dr. Chen and colleagues analyzed data from two independent cohorts with 7,893 patients and 46,880 patients each.
They first characterized the relationship between PNPLA3 genotype and cirrhosis via univariable and multivariable analyses. These efforts revealed that the genotype predicted cirrhosis in both cohorts, with associations also detected for well-documented clinical risk factors, including diabetes, obesity, and high ALT. Of note, PNPLA3 genotype demonstrated an additive effect for cirrhosis when detected in conjunction with these risks.
Further analysis revealed that homozygous carriers of PNPLA3 p.I148M with indeterminate FIB4 scores (1.3-2.67) and diabetes had an incidence rate of cirrhosis on par with patients who had high-risk FIB4 (greater than 2.67).
The effects of the risk allele were also made evident by comparing patients with diabetes and indeterminate FIB4 based on presence or absence of the marker – those testing positive for h PNPLA3 p.I148M had 2.9-4.8 times greater risk of cirrhosis. Conversely, patients with FIB4 scores less than 1.3, regardless of other risk factors, had little change in cirrhosis rate regardless of PNPLA3 status.
“We found that PNPLA3 genotyping in conjunction with clinical risk factors may improve risk stratification in patients with NAFLD,” the investigators concluded. “Although it may be possible to develop more complex polygenic risk scores for cirrhosis, these findings suggest that genotyping of PNPLA3 alone, which is less expensive than genomewide genotyping and easier to understand, may have similar clinical applicability for NAFLD.”
Dr. Chen and colleagues therefore recommended that NAFLD patients with metabolic risk factors (particularly diabetes) and indeterminate FIB4 routinely undergo PNPLA3 genotyping, with referral to hepatology if positive for two risk alleles.
The study was supported by the American Association for the Study of Liver Diseases, National Institutes of Health, and the University of Michigan department of internal medicine. The investigators disclosed no conflicts of interest.

Liquid albuterol shortage effects reduced by alternative drugs, similar shortages may be increasingly common
The shortage of 0.5% albuterol sulfate inhalation solution, first reported by the FDA last October, gained increasing attention earlier this month when Akorn Pharmaceuticals – one of just two companies making the product – shut down after years of financial and regulatory troubles.
The other manufacturer, Nephron Pharmaceuticals, is producing 0.5% albuterol “as fast as possible” to overcome the shortage, CEO Lou Kennedy said in a written comment.
Meanwhile, the more commonly used version of liquid albuterol, with a concentration of 0.083%, remains in “good supply from several manufacturers,” according to an FDA spokesperson.
Still, headlines concerning the shortage have caused “a bit of a panic” for patients with asthma and parents with asthmatic children, according to David R. Stukus, MD, professor of clinical pediatrics in the division of allergy and immunology at Nationwide Children’s, Columbus, Ohio.
Much of the media coverage has lacked context, causing unnecessary worry, he said, as the shortage only affects one type of albuterol generally reserved for inpatient and emergency use.
“The shortage has not impacted our albuterol inhalers thus far,” Dr. Stukus said in an interview. “So I certainly don’t want people with asthma to panic that they’re going to run out of their inhaler anytime soon.”
Even infants and toddlers can use inhalers
Although Dr. Stukus noted that certain patients do require nebulizers, such as those with conditions that physically limit their breathing, like muscular dystrophy, most patients can use inhalers just fine. He said it’s a “pretty common misconception, even among medical professionals,” that infants and toddlers need nebulizers instead.
“In our institution, for example, we rarely ever start babies on a nebulizer when we diagnose them with asthma,” Dr. Stukus said. “We often just start right away with an inhaler with a spacer and a face mask.”
The shortage of liquid albuterol may therefore have a silver lining, he suggested, as it prompts clinicians to reconsider their routine practice.
“When situations like this arise, it’s a great opportunity for all of us to just take a step back and reevaluate the way we do things,” Dr. Stukus said. “Sometimes we just get caught up with inertia and we continue to do things the same way even though new options are available, or evidence has changed to the contrary.”
Nathan Rabinovitch, MD, professor of pediatrics in the division of pediatric allergy and clinical immunology at National Jewish Health, Denver, said that his center had trouble obtaining liquid albuterol about 2 weeks ago, so they pivoted to the more expensive levalbuterol for about a week and a half, until their albuterol supply was restored.
While Dr. Rabinovitch agreed that most children don’t need a nebulizer, he said about 5%-10% of kids with severe asthma should have one on hand in case their inhaler fails to control an exacerbation.
Personal preferences may also considered, he added.
“If [a parent] says, ‘I like to use the nebulizer. The kid likes it,’ I’m fine if they just use a nebulizer.”
One possible downside of relying on a nebulizer, however, is portability, according to Kelly O’Shea, MD, assistant professor in the division of allergy and clinical immunology at the University of Michigan, Ann Arbor.
“If you’re out at the park or out at a soccer game with your kids, and they are having trouble breathing ... and they need their albuterol, you don’t have that ability if you are tied to a nebulizer,” Dr. O’Shea said in an interview. “As long as a parent feels comfortable – they feel like [their child] can get deep breaths in, I agree that you can use [an inhaler] in the infant and toddler population.”
She also agreed that a nebulizer may serve as a kind of second step if an inhaler isn’t controlling an exacerbation; however, she emphasized that a nebulizer should not be considered a replacement for professional care, and should not give a false sense of security.
“I caution parents to make sure that when they need it, they also take the next step and head over to the emergency room,” Dr. O’Shea said.
Generic drug shortages becoming more common
While the present scarcity of liquid albuterol appears relatively mild in terms of clinical impact, it brings up broader concerns about generic drug supply, and why shortages like this are becoming more common, according to Katie J. Suda, PharmD, MS, professor of medicine and pharmacy, and associate director, center for pharmaceutical policy and prescribing at the University of Pittsburgh.
“Drug shortages continue to increase in frequency, and the duration and severity of the shortages are also getting worse,” Dr. Suda said in an interview.
The reasons for these shortages can be elusive, according to 2022 report by the American Society of Health-System Pharmacists, which found that more than half of shortages came with no explanation from manufacturers.
The same report showed that only 5% of shortages were due to a “business decision,” but this factor is likely more central than publicly stated.
A recent FDA analysis on drug shortages, for instance, lists “lack of incentives to produce less profitable drugs,” as the first “root cause,” and Dr. Suda agrees.
“It’s important that we have generic medicines to decrease costs to our health systems, as well as for our patients,” Dr. Suda said. “But frequently, with those generic products, the price is driven so low that it increases the risk of a shortage.”
The drive to maintain profit margins may motivate companies to cut corners in production, Dr. Suda explained. She emphasized that this connection is speculative, because motivations are effectively unknowable, but the rationale is supported by past and present shortages.
Akorn Pharmaceuticals, for example, received a warning letter from the FDA in 2019 because of a variety of manufacturing issues, including defective bottles, questionable data, and metal shavings on aseptic filling equipment.
When a manufacturer like Akorn fails, the effects can be far-reaching, Dr. Suda said, noting their broad catalog of agents. Beyond liquid albuterol, Akorn was producing cardiac drugs, antibiotics, vitamins, local anesthetics, eye products, and others.
Drug shortages cause “a significant strain on our health care system,” Dr. Suda said, and substituting other medications increases risk of medical errors.
Fortunately, the increasing number of drug shortages is not going unnoticed, according to Dr. Suda. The FDA and multiple other organizations, including the ASHP, American Medical Association, and National Academies of Sciences, Engineering, and Medicine, are all taking steps to ensure that essential medicines are in steady supply, including moves to gather more data from manufacturers.
“I hope that a lot of the efforts that are moving forward ... will help us decrease the impact of shortages on our patients,” Dr. Suda said.

Review explores the boundaries of endoscopic resection for esophageal adenocarcinoma
A growing body of evidence shows that deeper and larger tumors can be safely removed with endoscopy instead of surgery when individual patient risk is taken into account, according to a review by Eva P.D. Verheij, a doctoral candidate at Amsterdam University Medical Center, and colleagues.
“Management of patients with superficial esophageal adenocarcinoma (EAC) is becoming less invasive and more patient-tailored,” the researchers wrote in Techniques and Innovations in Gastrointestinal Endoscopy. “In the future, watchful waiting may be a valid alternative to surgery in selected cases.”
The investigators examined new advances that have been made in the management of superficial esophageal adenocarcinomas by endoscopy, and they address how guidelines may be falling short in light of newly published evidence.
Surgery is usually the first choice for the management of advanced esophageal adenocarcinoma. “Endoscopic treatment has become the cornerstone for early cancer confined to the mucosa,” the authors wrote.
“For low-risk submucosal EAC, which only invades the superficial submucosa (sm1, i.e. less than 500 mcm) without any other risk factors, endoscopic treatment as an alternative to surgery is gaining acceptance because multiple studies have demonstrated a very low risk of lymph node metastases (less than 2% for these lesions),” the investigators wrote. Although surgical resection with lymphadenectomy is currently the recommended treatment for cases with deep submucosal invasion, poor differentiation, or lymphovascular invasion, the investigators suggested that even these tumors may be within an endoscopist’s reach.
While the rate of lymph node metastasis for such patients has been reported to be as high as 46%, more recent endoscopic studies show a metastasis rate range of up to 20% after 23-63 months of follow-up.
“One possible explanation for the discrepancy in lymph node metastases rates between surgical and endoscopic studies could be the different preparation of slides for histopathological assessment,” the investigators wrote. “In general, the cuts in surgical specimen are made with wider intervals (±5 mm) than the cuts in endoscopic resection specimens (2-3 mm), with additional cuts in case of submucosal invasion. The hypothesis is that this wider interval may result in missing the area with the deepest tumor infiltration. This could result in an underdiagnosis of the actual invasion depth, and therefore an overestimation of the associated lymph node metastases risk.” A study published in August 2022 in Gastrointestinal Endoscopy found an annual metastases risk of 6.9% in patients with high-risk T1a EAC.
“Given its invasiveness and associated morbidity and mortality, esophagectomy may be overtreatment in those patients who will not develop lymph node metastases,” the investigators wrote. “Given the technical advances in endoscopy that enable us to radically remove large EACs, and to perform more meticulous follow-up, it might be time to swing the pendulum and only send those patients for surgery who have an indisputable indication for surgery, instead of performing esophagectomy as a prophylactic treatment.”
To truly find the limits of endoscopic resection for EAC, however, more research is needed.
“Ongoing studies are necessary to evaluate the lymph node metastases risk on an individual basis, using presence of histological risk factors. By predicting the risk of lymph node metastases, and considering patients’ wishes and condition, one might decide to perform esophagectomy or watchful waiting with strict endoscopic follow-up. In high-risk cases, we may use sentinel node navigated surgery in the future as an extra safety check before deciding on optimal management,” the authors wrote.
The investigators disclosed relationships Medtronic, C2 Therapeutics/Pentax Medical, MicroTech, and Aqua Medical.
Barrett’s esophagus (BE) is the only known precursor lesion to esophageal adenocarcinoma, a cancer with rising incidence and stage-dependent survival. Early detection of BE-related neoplasia provides the opportunity to intervene through endoscopic eradication therapy and avoid the morbidity associated with esophagectomy. Verheji and colleagues, a group from a robust BE expert center in the Netherlands, provide a comprehensive and detailed overview of the role of endoscopic therapy for superficial esophageal adenocarcinoma (EAC), which is gaining popularity. In this review, they nicely highlight the benefits of this approach as a minimally invasive, organ-preserving, safe, and effective treatment option.

A growing body of evidence shows that deeper and larger tumors can be safely removed with endoscopy instead of surgery when individual patient risk is taken into account, according to a review by Eva P.D. Verheij, a doctoral candidate at Amsterdam University Medical Center, and colleagues.
“Management of patients with superficial esophageal adenocarcinoma (EAC) is becoming less invasive and more patient-tailored,” the researchers wrote in Techniques and Innovations in Gastrointestinal Endoscopy. “In the future, watchful waiting may be a valid alternative to surgery in selected cases.”
The investigators examined new advances that have been made in the management of superficial esophageal adenocarcinomas by endoscopy, and they address how guidelines may be falling short in light of newly published evidence.
Surgery is usually the first choice for the management of advanced esophageal adenocarcinoma. “Endoscopic treatment has become the cornerstone for early cancer confined to the mucosa,” the authors wrote.
“For low-risk submucosal EAC, which only invades the superficial submucosa (sm1, i.e. less than 500 mcm) without any other risk factors, endoscopic treatment as an alternative to surgery is gaining acceptance because multiple studies have demonstrated a very low risk of lymph node metastases (less than 2% for these lesions),” the investigators wrote. Although surgical resection with lymphadenectomy is currently the recommended treatment for cases with deep submucosal invasion, poor differentiation, or lymphovascular invasion, the investigators suggested that even these tumors may be within an endoscopist’s reach.
While the rate of lymph node metastasis for such patients has been reported to be as high as 46%, more recent endoscopic studies show a metastasis rate range of up to 20% after 23-63 months of follow-up.
“One possible explanation for the discrepancy in lymph node metastases rates between surgical and endoscopic studies could be the different preparation of slides for histopathological assessment,” the investigators wrote. “In general, the cuts in surgical specimen are made with wider intervals (±5 mm) than the cuts in endoscopic resection specimens (2-3 mm), with additional cuts in case of submucosal invasion. The hypothesis is that this wider interval may result in missing the area with the deepest tumor infiltration. This could result in an underdiagnosis of the actual invasion depth, and therefore an overestimation of the associated lymph node metastases risk.” A study published in August 2022 in Gastrointestinal Endoscopy found an annual metastases risk of 6.9% in patients with high-risk T1a EAC.
“Given its invasiveness and associated morbidity and mortality, esophagectomy may be overtreatment in those patients who will not develop lymph node metastases,” the investigators wrote. “Given the technical advances in endoscopy that enable us to radically remove large EACs, and to perform more meticulous follow-up, it might be time to swing the pendulum and only send those patients for surgery who have an indisputable indication for surgery, instead of performing esophagectomy as a prophylactic treatment.”
To truly find the limits of endoscopic resection for EAC, however, more research is needed.
“Ongoing studies are necessary to evaluate the lymph node metastases risk on an individual basis, using presence of histological risk factors. By predicting the risk of lymph node metastases, and considering patients’ wishes and condition, one might decide to perform esophagectomy or watchful waiting with strict endoscopic follow-up. In high-risk cases, we may use sentinel node navigated surgery in the future as an extra safety check before deciding on optimal management,” the authors wrote.
