The American Gastroenterological Association (AGA) has released an expert review and clinical practice update focusing on esophageal dysfunction caused by immune-mediated and infectious diseases.

“Many different disorders can lead to esophageal dysfunction, which is characterized by symptoms including dysphagia, odynophagia, chest pain and heartburn. These symptoms can be caused either by immune or infectious conditions and can either be localized to the esophagus or part of a larger systemic process,” co–first author Emily McGowan, MD, PhD, with the division of allergy and immunology, University of Virginia School of Medicine, Charlottesville, said in an AGA podcast. 

However, without a “high index of suspicion,” these conditions can be overlooked, leading to delays in diagnosis and unnecessary procedures. “With this clinical practice update, we wanted to help providers more readily recognize these conditions so that patients can be diagnosed and treated earlier in the course of their disease,” McGowan explained. 

 

“This is a fantastic review that highlights how many different systemic disorders can affect the esophagus,” Scott Gabbard, MD, gastroenterologist and section head at the Center for Neurogastroenterology and Motility, Cleveland Clinic, Ohio, who wasn’t involved in the review, said in an interview.

“Honestly, for the practicing gastroenterologist, this is one of those reviews that I could envision someone either saving to his or her desktop for reference or printing it and pinning it next to his or her desk,” Gabbard said.

 

Best Practice Advice

The clinical practice update is published in Clinical Gastroenterology and Hepatology. It includes 10 “best practice advice” statements and a table highlighting “important” considerations when evaluating patients with esophageal dysfunction.

The review authors note that esophageal dysfunction may result from localized infections — most commonly Candida, herpes simplex virus, and cytomegalovirus — or systemic immune-mediated diseases, such as systemic sclerosis (SSc), mixed connective tissue disease (MCTD), and eosinophilic esophagitis (EoE).

They advise clinicians to identify if there are risks for inflammatory or infectious possibilities for a patient’s esophageal symptoms and investigate for these disorders as a potential cause of esophageal dysfunction.

Once esophageal infection is identified, it’s important to identify whether accompanying signs and symptoms point to immunocompromise leading to a more systemic infection. Consultation with an infectious disease expert is recommended to guide appropriate treatment, the authors said.

If symptoms fail to improve after therapy for infectious esophagitis, the patient should be evaluated for refractory infection or additional underlying sources of esophageal and immunologic dysfunction is advised.

It’s also important to recognize that patients with EoE who continue to have symptoms of esophageal dysfunction despite histologic and endoscopic disease remission, may develop a motility disorder and evaluation of esophageal motility may be warranted, the authors said. 

In patients with histologic and endoscopic features of lymphocytic esophagitis, treatment of lymphocytic-related inflammation with proton-pump inhibitor (PPI) therapy or swallowed topical corticosteroids and esophageal dilation as needed should be considered.

In patients who present with esophageal symptoms in the setting of hypereosinophilia (absolute eosinophil count > 1500 cells/uL), the authors advise further workup of non-EoE eosinophilic gastrointestinal disease, hypereosinophilic syndrome, and eosinophilic granulomatosis with polyangiitis should be considered, with consultation with an allergy/immunology specialist if helpful.

In patients with rheumatologic diseases, especially SSc and MCTD, it’s important to be aware that esophageal symptoms can occur because of involvement of the esophageal muscle layer, resulting in dysmotility and/or incompetence of the lower esophageal sphincter, they said.

In the setting of Crohn’s disease, some patients can develop esophageal involvement from inflammation, stricturing, or fistulizing changes with granulomas seen histologically. Esophageal manifestations of Crohn’s disease tend to occur in patients with active intestinal disease.

In patients with dermatologic diseases of lichen planus or bullous disorders, dysphagia can occur because of endoscopically visible esophageal mucosal involvement. Esophageal lichen planus, in particular, can occur without skin involvement and can be difficult to define on esophageal histopathology.

The authors also advise clinicians to consider infectious and inflammatory causes of secondary achalasia during initial evaluation.

“Achalasia and EoE might coexist more commonly than what gastroenterologists think, especially in younger patients,” co–first author Chanakyaram Reddy, MD, a gastroenterologist with Baylor University Medical Center, Dallas, Texas, said in the AGA podcast. 

He noted that in a recent population-based study, the estimated relative risk of EoE was over 30-fold higher in patients with achalasia aged ≤ 40 years. 

“In any suspected achalasia case, it would be wise to obtain biopsies throughout the entire esophagus when the patient is off confounding medications such as PPI therapy to establish if significant esophageal eosinophilia is coexistent,” Reddy said.

“If EoE-level eosinophilia is found, it would be reasonable to consider treating medically for EoE prior to committing to achalasia-specific interventions, which often involve permanent disruption of the esophageal muscle layer,” he added.

Gabbard said this review helps the clinician think beyond gastroesophageal reflux disease (GERD) — the most common cause of esophageal dysfunction — and consider other causes for esophageal dysfunction. 

“We are seeing more complex disorders affect the esophagus. It’s not just GERD and you absolutely need a high index of suspicion because you can find varying disorders to blame for many esophageal symptoms that could otherwise be thought to be just reflux,” he said.

This research had no commercial funding. Disclosures for the authors are listed with the original article. Gabbard had no relevant disclosures.

The American Gastroenterological Association (AGA) has released a clinical practice update synthesizing current available evidence and expert opinion on peroral endoscopic myotomy (POEM) to treat achalasia and other esophageal motility disorders.

“Any patient suspected to have achalasia, or difficulty swallowing for that matter, should undergo a comprehensive diagnostic workup, and that should include clinical history, review of medication, as well as tests. The diagnosis should not be based on isolated tests but on the clinical picture as a whole,” first author Dennis Yang, MD, AGAF, with the Center for Interventional Endoscopy, AdventHealth, Orlando, Florida, noted in an AGA podcast about the update.

 

The clinical practice update, published in Gastroenterology, includes 12 “best practice advice” statements.

Since its introduction to clinical practice more than a decade ago, POEM has matured and gained widespread acceptance because of its efficacy and safety profile.

POEM has at least similar outcomes to laparoscopic Heller myotomy and pneumatic dilation for type I and type II achalasia with better results for those with type III achalasia, Yang noted.

“However, besides disease phenotype, we need to remember that choosing the right treatment for the patient is going to be based on multiple factors including patient characteristics as well as local expertise,” Yang added.

In terms of technical considerations, the update states that both anterior and posterior tunnel approaches demonstrate comparable success and postprocedure reflux rates. Tunnel orientation should be tailored to the patient’s surgical history and endoscopist’s preference.

It further states that optimal length of the myotomy in the esophagus and cardia, as it pertains to treatment efficacy and risk for postprocedure reflux, remains to be determined.

Adjunct techniques, including real-time intraprocedure functional luminal impedance planimetry, may be considered to tailor or confirm the adequacy of the myotomy.

Same-day discharge after POEM can be considered in select patients who meet discharge criteria. Patients with advanced age, significant comorbidities, poor social support, and/or access to specialized care should be considered for hospital admission, irrespective of symptoms.

The update notes that specific guidelines on the role and extent of antibiotic prophylaxis before and after POEM are lacking. A single dose of antibiotics at the time of POEM “may be sufficient” for antibiotic prophylaxis.

In terms of immediate post-POEM care, the update notes that the clinical impact of routine esophagram or endoscopy immediately post-POEM remains unclear. Testing can be considered based on local practice preferences and in cases in which intraprocedural events or postprocedural findings warrant further evaluation.

Proton pump inhibitors are recommended immediately following POEM, as gastroesophageal reflux disease (GERD) is common following POEM, occurring in up to 65% of cases.

Routine endoscopic surveillance is advised to monitor GERD, disease progression, and esophageal cancer risk, which is significantly higher in achalasia patients.

“Just like diabetes and hypertension, we need to remember that achalasia is a chronic disease and long-term postprocedural surveillance is strongly encouraged to monitor disease progression as well as potential complications of reflux,” Yang said.

He noted that surveillance should be considered irrespective of patient symptoms because many of these patients may remain asymptomatic.

“Primary gastroenterologists should have a very low threshold in referring the patient back to the POEM endoscopist or any specialized esophageal center because the ideology of symptoms in these patients can be quite difficult to tease out and often require comprehensive diagnostic workup,” Yang said.

Evidence for POEM in esophagogastric outflow obstruction and other nonachalasia spastic motility disorders is limited and should only be considered on a case-by-case basis after other less invasive approaches have been exhausted, the update states.

 

For perspective on the POEM clinical practice update, this news organization spoke with Mouen Khashab, MD, director of therapeutic endoscopy, Johns Hopkins University, Baltimore, Maryland.

“The document is very well written and comprehensive,” Khashab said.

However, Khashab said he would have liked to see greater emphasis on the value or role of a short myotomy in the esophagus and cardia.

“There is level I evidence that the short esophageal myotomy is equivalent to a long esophageal myotomy for type I and II achalasia. When you do a short myotomy, you save procedure time and there is potentially a lower incidence of blown-out myotomy or BOM,” Khashab said.

Khashab also noted that a long myotomy on the gastric side “likely increases the risk of reflux disease, and therefore a limited myotomy on the gastric side likely also is advantageous.”

This research had no commercial funding. Yang serves as a consultant for Boston Scientific, Olympus, FujiFilm, Microtech, Medtronic, 3D-Matrix, and Neptune Medical, and has received research support from Microtech and 3D-Matrix. Khashab had no relevant disclosures.

Brief Introduction to the SGM Communities

The sexual and gender minority (SGM) communities (see Table 1), also termed “LGBTQIA+ community” (lesbian, gay, bisexual, transgender, queer, intersex, asexual, plus — including two spirit) are historically minoritized with unique risks for inequities in gastrointestinal health outcomes.¹ These potential disparities remain largely uninvestigated because of continued systemic discrimination and inadequate collection of sexual orientation and gender identity (SOGI) data,² with the National Institutes of Health Sexual & Gender Minority Research Office (SGMRO) having been instructed to address these failures. There is increased SGM self-identification (7.1% of all people in the United States and 20.8% of generation Z).³ Given the high worldwide prevalence of disorders of gut-brain interaction (DGBIs)and the influence of biopsychosocial determinants of health in DGBI incidence,⁴ it becomes increasingly likely that research in DGBI-related factors in SGM people will be fruitful.

Disorders of Gut-Brain Interaction and the Potential Minority Stress Link in SGM People

DGBIs are gastrointestinal conditions that occur because of brain-gut axis dysregulation. There is evidence that chronic stress and trauma negatively influence brain-gut interaction, which likely results in minority communities who face increased levels of trauma, stress, discrimination, and social injustice being at higher risk of DGBI development.^5-7 Given increased rates of trauma in the SGM community, practicing trauma-informed care is essential to increase patient comfort and decrease the chance of retraumatization in medical settings.⁸ Trauma-informed care focuses on how trauma influences a patient’s life and response to medical care. To practice trauma-informed care, screening for trauma when appropriate, actively creating a supportive environment with active listening and communication, with informing the patient of planned actions prior to doing them, like physical exams, is key.

Trauma-Informed Care: Examples of Verbiage

Asking about Identity

• Begin by introducing yourself with your pronouns to create a safe environment for patient disclosure. Example: “Hello, I am Dr. Kara Jencks, and my pronouns are she/her. I am one of the gastroenterologists here at XYZ Clinic. How would you prefer to be addressed?”
• You can also wear a pronoun lapel pin or a pronoun button on your ID badge to indicate you are someone who your patient can be themselves around.
• The easiest way to obtain sexual orientation and gender identity is through intake forms. Below are examples of how to ask these questions on intake forms. It is important to offer the option to select more than one option when applicable and to opt out of answering if the patient is not comfortable answering these questions.

Sample Questions for Intake Forms

1. What is your sex assigned at birth? (Select one)

• Female
• Male
• Intersex
• Do not know
• Prefer not to disclose

2. What is your gender identity? (Select all that apply)

• Nonbinary
• Gender queer
• Woman
• Man
• Transwoman
• Transman
• Gender fluid
• Two-spirit
• Agender
• Intersex
• Other: type in response
• Prefer not to disclose

3. What are your pronouns? (Select all that apply)

• They/them/theirs
• She/her/hers
• He/him/his
• Zie/zir/zirs
• Other: type in response
• Prefer not to disclose

4. What is your sexual orientation? (Select all that apply)

• Bisexual
• Pansexual
• Queer
• Lesbian
• Gay
• Asexual
• Demisexual
• Heterosexual or straight
• Other: type in response
• Prefer not to disclose

Screening for Trauma

While there are questionnaires that exist to ask about trauma history, if time allows, it can be helpful to screen verbally with the patient. See reference number 8, for additional prompts and actions to practice trauma-informed care.

• Example: “Many patients with gastrointestinal symptoms and disorders have experienced trauma in the past. We do our best to ensure we are keeping you as comfortable as possible while caring for you. Are you comfortable sharing this information? [if yes->] Do you have a history of trauma, including physical, emotional, or sexual abuse? ... Have these experiences impacted the way in which you navigate your healthcare? ... Is there anything we can do to make you more comfortable today?”

General Physical Examination

Provide details for what you are going to do before you do it. Ask for permission for the examination. Here are two examples:

• “I would like to perform a physical exam to help better understand your symptoms. Is that okay with you?”
• “I would like to examine your abdomen with my stethoscope and my hands. Here is a sheet that we can use to help with your privacy. Please let me know if and when you feel any tenderness or pain.”

Rectal Physical Examination

Let the patient know why it would be helpful to perform a rectal exam, what the rectal exam will entail, and the benefits and risks to doing a rectal exam. An example follows:

• “Based on the symptoms you are describing, I think it would be helpful to perform a rectal exam to make sure you don’t have any fissures or hemorrhoids on the outside around the anus, any blockages or major issues inside the rectum, and to assess the strength and ability of your nerves and muscles or the pelvic floor to coordinate bowel movements. There are no risks aside from discomfort. If it is painful, and you would like me to stop, you tell me to stop, and I will stop right away. What questions do you have? Are we okay to proceed with the rectal exam?”
• “Please pull down your undergarments and your pants to either midthigh, your ankles, or all the way off, whatever your preference is, lie down on the left side on the exam table, and cover yourself with this sheet. In the meantime, I will be getting a chaperone to keep us safe and serve as a patient advocate during the procedure.”
• Upon returning to the exam room: “Here is Sara, who will be chaperoning today. Let myself or Sara know if you are uncomfortable or having pain during this exam. I will be lifting up the sheet to get a good look around the anus. [lifts up sheet] You will feel my hand helping to spread apart the buttocks. I am looking around the anus, and I do not see any fissures, hemorrhoids, or anything else concerning. Please squeeze in like you are trying to hold in gas. Please bear down like you are trying to have a bowel movement or let out gas. Okay, now you may feel some cold gel around the anus, and you will feel my finger go inside. Take a deep breath in. Do you feel any pain as I palpate? Please squeeze in like you are trying to hold in gas. Please bear down like you are trying to have a bowel movement or let out gas. I will be stopping the exam now.”
• You would then wash your hands and allow the patient to get dressed, and then disclose the exam findings and the rest of your visit.

Ilan H. Meyer coined the minority stress model when discussing mental health disorders in SGM patients in the early 2000s.⁹ With it being well known that DGBIs can overlap with (but are not necessarily caused by) mental health disorders, this model can easily apply to unify multiple individual and societal factors that can combine to result in disorders of brain-gut interaction (see Figure 1) in SGM communities. Let us keep this framework in mind when evaluating the following cases. 

 

Case Presentations

Case 1

A 56-year-old man (pronouns: he/him) assigned male sex at birth, who identifies as gay, presents to your gastroenterology clinic for treatment-refractory constipation-predominant irritable bowel syndrome. It has impacted his sexual function. Outside hospital records report a normal colonoscopy 1 year ago and an unremarkable abdominal computerized tomography 4 months ago, aside from increased stool burden in the entire colon. He has tried to use enemas prior to sex, though these do not always help. Fiber-rich diet and fermentable food avoidance has not been successful. He is currently taking two capfuls of polyethylene glycol 3350 twice per day, as well as senna at night and continues to have a bowel movement every 2-3 days that is Bristol stool form scale type 1-2 unless he uses enemas. How do you counsel this patient about his IBS-C and rectal discomfort?

After assessing for sexual violence or other potential trauma-related factors, your digital rectal examination suggests that an anorectal defecatory disorder is less likely with normal relaxation and perineal movement. You recommend linaclotide. He notices improvement within 1 week, with improved comfort during anoreceptive sex. 

 

Case 2

A 30-year-old woman (pronouns: she/her) assigned male sex at birth who has sex with men underwent vaginoplasty 2 years ago and is referred to the gastroenterology clinic for fecal incontinence and diarrhea. On review of her anatomic inventory, her vaginoplasty was a penile inversion vaginoplasty (no intestinal tissue was used for creation), and her prostate was left intact. The vaginal vault was created in between the urethra and rectum, similar to the pelvic floor anatomy of a woman assigned female sex at birth. Blood, imaging, and endoscopic workup has been negative. She is also not taking any medications associated with diarrhea, only taking estrogen and spironolactone. The diarrhea is not daily, but when present, about once per week, can be up to 10 episodes per day, and she has a sense of incomplete evacuation regularly. She notes having a rectal exam in the past but is not sure if her pelvic floor muscles have ever been assessed. How do you manage this patient?

To complete her evaluation in the office, you perform a trauma-informed rectal exam which reveals a decreased resting anal sphincter tone and paradoxical defecatory maneuvers without tenderness to the puborectalis muscle. Augmentation of the squeeze is also weak. Given her pelvic floor related surgical history, her symptoms, and her rectal exam, you recommend anorectal manometry which is abnormal and send her for anorectal biofeedback pelvic floor physical therapy, which improves her symptoms significantly. 

Case 3

A 36-year-old woman (pronouns: she/her) assigned female sex at birth, who identifies as a lesbian, has a history of posttraumatic stress disorder and chronic nausea and vomiting that has begun to affect her quality of life. She notes the nausea and vomiting used to be managed well with evening cannabis gummies, though in the past 3 months, the nausea and vomiting has worsened, and she has lost 20 pounds as a result. As symptom predated cannabis usage, cannabis hyperemesis syndrome (CHS) was less likely (an important point as she has been stigmatized during prior encounters for her cannabis usage). Her primary care physician recommended a gastroscopy which was normal, aside from some residual solid food material in the stomach. Her bowel movements are normal, and she doesn’t have other gastrointestinal symptoms. She and her wife are considering having a third child, so she is worried about medications that may affect pregnancy or breast-feeding. How do you manage her nausea and vomiting?

After validating her concerns and performing a trauma-informed physical exam and encounter, you recommend a 4-hour gastric emptying test with a standard radiolabeled egg meal. Her gastric emptying does reveal significantly delayed gastric emptying at 2 and 4 hours. You discuss the risks and benefits of lifestyle modification (smaller frequent meals), initiating medications (erythromycin and metoclopramide) or cessation of cannabis (despite low likelihood of CHS). Desiring to avoid starting medications around initiation of pregnancy, she opts for the dietary approach and cessation of cannabis. You see her at a follow-up visit in 6 months, and her nausea is now only once a month, and she is excited to begin planning for a pregnancy using assisted reproductive technology. 

 

Case 4

A 20-year-old nonbinary intersex individual (pronouns: he/they) (incorrectly assigned female at birth — is intersex with congenital adrenal hyperplasia) presents to the gastroenterology clinic with 8 years of heartburn, acid reflux, postprandial bloating, alternating diarrhea and constipation, nausea, and vomiting, complicated by avoidant restrictive food intake disorder. They have a history of bipolar II disorder with prior suicidal ideation. He has not yet had diagnostic workup as he previously had a bad encounter with a gastroenterologist where the gastroenterologist blamed his symptoms on his gender-affirming therapy, misgendered the patient, and told the patient their symptoms were “all in her [sic] head.”

You recognize that affirming their gender and using proper pronouns is the best first way to start rapport and help break the cycle of medicalized trauma. You then recommend a holistic work up with interdisciplinary management because of the complexity of his symptoms. For testing, you recommend a colonoscopy, upper endoscopy, a gastric emptying test with a 48-hour transit scintigraphy test, anorectal manometry, a dietitian referral, and a gastrointestinal psychology referral. Their anorectal manometry is consistent with an evacuation disorder. The rest of the work up is unremarkable. You diagnose them with anorectal pelvic floor dysfunction and functional dyspepsia, recommending biofeedback pelvic floor physical therapy, a proton-pump inhibitor, and neuromodulation in coordination with psychiatry and psychology to start with a plan for follow-up. The patient appreciates you for helping them and listening to their symptoms. 

 

Discussion

When approaching DGBIs in the SGM community, it is vital to validate their concerns and be inclusive with diagnostic and treatment modalities. The diagnostic tools and treatments for DGBI are not different for patients in the SGM community. Like with other patients, trauma-informed care should be utilized, particularly given higher rates of trauma and discrimination in this community. Importantly, their DGBI is not a result of their sexual orientation or gender identity, and hormone therapy is not the cause of their DGBI. Recommending cessation of gender-affirming care or recommending lifestyle measures against their identity is generally not appropriate or necessary. With increased scrutiny being a reality of SGM people’s existence in recent years, cultural humility is needed to establish the rapport necessary to treat DGBIs among members of the SGM communities.

Brief Introduction to the SGM Communities

The sexual and gender minority (SGM) communities (see Table 1), also termed “LGBTQIA+ community” (lesbian, gay, bisexual, transgender, queer, intersex, asexual, plus — including two spirit) are historically minoritized with unique risks for inequities in gastrointestinal health outcomes.¹ These potential disparities remain largely uninvestigated because of continued systemic discrimination and inadequate collection of sexual orientation and gender identity (SOGI) data,² with the National Institutes of Health Sexual & Gender Minority Research Office (SGMRO) having been instructed to address these failures. There is increased SGM self-identification (7.1% of all people in the United States and 20.8% of generation Z).³ Given the high worldwide prevalence of disorders of gut-brain interaction (DGBIs)and the influence of biopsychosocial determinants of health in DGBI incidence,⁴ it becomes increasingly likely that research in DGBI-related factors in SGM people will be fruitful.

Disorders of Gut-Brain Interaction and the Potential Minority Stress Link in SGM People

DGBIs are gastrointestinal conditions that occur because of brain-gut axis dysregulation. There is evidence that chronic stress and trauma negatively influence brain-gut interaction, which likely results in minority communities who face increased levels of trauma, stress, discrimination, and social injustice being at higher risk of DGBI development.^5-7 Given increased rates of trauma in the SGM community, practicing trauma-informed care is essential to increase patient comfort and decrease the chance of retraumatization in medical settings.⁸ Trauma-informed care focuses on how trauma influences a patient’s life and response to medical care. To practice trauma-informed care, screening for trauma when appropriate, actively creating a supportive environment with active listening and communication, with informing the patient of planned actions prior to doing them, like physical exams, is key.

Trauma-Informed Care: Examples of Verbiage

Asking about Identity

• Begin by introducing yourself with your pronouns to create a safe environment for patient disclosure. Example: “Hello, I am Dr. Kara Jencks, and my pronouns are she/her. I am one of the gastroenterologists here at XYZ Clinic. How would you prefer to be addressed?”
• You can also wear a pronoun lapel pin or a pronoun button on your ID badge to indicate you are someone who your patient can be themselves around.
• The easiest way to obtain sexual orientation and gender identity is through intake forms. Below are examples of how to ask these questions on intake forms. It is important to offer the option to select more than one option when applicable and to opt out of answering if the patient is not comfortable answering these questions.

Sample Questions for Intake Forms

1. What is your sex assigned at birth? (Select one)

• Female
• Male
• Intersex
• Do not know
• Prefer not to disclose

2. What is your gender identity? (Select all that apply)

• Nonbinary
• Gender queer
• Woman
• Man
• Transwoman
• Transman
• Gender fluid
• Two-spirit
• Agender
• Intersex
• Other: type in response
• Prefer not to disclose

3. What are your pronouns? (Select all that apply)

• They/them/theirs
• She/her/hers
• He/him/his
• Zie/zir/zirs
• Other: type in response
• Prefer not to disclose

4. What is your sexual orientation? (Select all that apply)

• Bisexual
• Pansexual
• Queer
• Lesbian
• Gay
• Asexual
• Demisexual
• Heterosexual or straight
• Other: type in response
• Prefer not to disclose

Screening for Trauma

While there are questionnaires that exist to ask about trauma history, if time allows, it can be helpful to screen verbally with the patient. See reference number 8, for additional prompts and actions to practice trauma-informed care.

• Example: “Many patients with gastrointestinal symptoms and disorders have experienced trauma in the past. We do our best to ensure we are keeping you as comfortable as possible while caring for you. Are you comfortable sharing this information? [if yes->] Do you have a history of trauma, including physical, emotional, or sexual abuse? ... Have these experiences impacted the way in which you navigate your healthcare? ... Is there anything we can do to make you more comfortable today?”

General Physical Examination

Provide details for what you are going to do before you do it. Ask for permission for the examination. Here are two examples:

• “I would like to perform a physical exam to help better understand your symptoms. Is that okay with you?”
• “I would like to examine your abdomen with my stethoscope and my hands. Here is a sheet that we can use to help with your privacy. Please let me know if and when you feel any tenderness or pain.”

Rectal Physical Examination

Let the patient know why it would be helpful to perform a rectal exam, what the rectal exam will entail, and the benefits and risks to doing a rectal exam. An example follows:

• “Based on the symptoms you are describing, I think it would be helpful to perform a rectal exam to make sure you don’t have any fissures or hemorrhoids on the outside around the anus, any blockages or major issues inside the rectum, and to assess the strength and ability of your nerves and muscles or the pelvic floor to coordinate bowel movements. There are no risks aside from discomfort. If it is painful, and you would like me to stop, you tell me to stop, and I will stop right away. What questions do you have? Are we okay to proceed with the rectal exam?”
• “Please pull down your undergarments and your pants to either midthigh, your ankles, or all the way off, whatever your preference is, lie down on the left side on the exam table, and cover yourself with this sheet. In the meantime, I will be getting a chaperone to keep us safe and serve as a patient advocate during the procedure.”
• Upon returning to the exam room: “Here is Sara, who will be chaperoning today. Let myself or Sara know if you are uncomfortable or having pain during this exam. I will be lifting up the sheet to get a good look around the anus. [lifts up sheet] You will feel my hand helping to spread apart the buttocks. I am looking around the anus, and I do not see any fissures, hemorrhoids, or anything else concerning. Please squeeze in like you are trying to hold in gas. Please bear down like you are trying to have a bowel movement or let out gas. Okay, now you may feel some cold gel around the anus, and you will feel my finger go inside. Take a deep breath in. Do you feel any pain as I palpate? Please squeeze in like you are trying to hold in gas. Please bear down like you are trying to have a bowel movement or let out gas. I will be stopping the exam now.”
• You would then wash your hands and allow the patient to get dressed, and then disclose the exam findings and the rest of your visit.

• You would then wash your hands and allow the patient to get dressed, and then disclose the exam findings and the rest of your visit.

Ilan H. Meyer coined the minority stress model when discussing mental health disorders in SGM patients in the early 2000s.⁹ With it being well known that DGBIs can overlap with (but are not necessarily caused by) mental health disorders, this model can easily apply to unify multiple individual and societal factors that can combine to result in disorders of brain-gut interaction (see Figure 1) in SGM communities. Let us keep this framework in mind when evaluating the following cases. 

 

Case Presentations

Case 1

A 56-year-old man (pronouns: he/him) assigned male sex at birth, who identifies as gay, presents to your gastroenterology clinic for treatment-refractory constipation-predominant irritable bowel syndrome. It has impacted his sexual function. Outside hospital records report a normal colonoscopy 1 year ago and an unremarkable abdominal computerized tomography 4 months ago, aside from increased stool burden in the entire colon. He has tried to use enemas prior to sex, though these do not always help. Fiber-rich diet and fermentable food avoidance has not been successful. He is currently taking two capfuls of polyethylene glycol 3350 twice per day, as well as senna at night and continues to have a bowel movement every 2-3 days that is Bristol stool form scale type 1-2 unless he uses enemas. How do you counsel this patient about his IBS-C and rectal discomfort?

After assessing for sexual violence or other potential trauma-related factors, your digital rectal examination suggests that an anorectal defecatory disorder is less likely with normal relaxation and perineal movement. You recommend linaclotide. He notices improvement within 1 week, with improved comfort during anoreceptive sex. 

 

Case 2

A 30-year-old woman (pronouns: she/her) assigned male sex at birth who has sex with men underwent vaginoplasty 2 years ago and is referred to the gastroenterology clinic for fecal incontinence and diarrhea. On review of her anatomic inventory, her vaginoplasty was a penile inversion vaginoplasty (no intestinal tissue was used for creation), and her prostate was left intact. The vaginal vault was created in between the urethra and rectum, similar to the pelvic floor anatomy of a woman assigned female sex at birth. Blood, imaging, and endoscopic workup has been negative. She is also not taking any medications associated with diarrhea, only taking estrogen and spironolactone. The diarrhea is not daily, but when present, about once per week, can be up to 10 episodes per day, and she has a sense of incomplete evacuation regularly. She notes having a rectal exam in the past but is not sure if her pelvic floor muscles have ever been assessed. How do you manage this patient?

To complete her evaluation in the office, you perform a trauma-informed rectal exam which reveals a decreased resting anal sphincter tone and paradoxical defecatory maneuvers without tenderness to the puborectalis muscle. Augmentation of the squeeze is also weak. Given her pelvic floor related surgical history, her symptoms, and her rectal exam, you recommend anorectal manometry which is abnormal and send her for anorectal biofeedback pelvic floor physical therapy, which improves her symptoms significantly. 

Case 3

A 36-year-old woman (pronouns: she/her) assigned female sex at birth, who identifies as a lesbian, has a history of posttraumatic stress disorder and chronic nausea and vomiting that has begun to affect her quality of life. She notes the nausea and vomiting used to be managed well with evening cannabis gummies, though in the past 3 months, the nausea and vomiting has worsened, and she has lost 20 pounds as a result. As symptom predated cannabis usage, cannabis hyperemesis syndrome (CHS) was less likely (an important point as she has been stigmatized during prior encounters for her cannabis usage). Her primary care physician recommended a gastroscopy which was normal, aside from some residual solid food material in the stomach. Her bowel movements are normal, and she doesn’t have other gastrointestinal symptoms. She and her wife are considering having a third child, so she is worried about medications that may affect pregnancy or breast-feeding. How do you manage her nausea and vomiting?

After validating her concerns and performing a trauma-informed physical exam and encounter, you recommend a 4-hour gastric emptying test with a standard radiolabeled egg meal. Her gastric emptying does reveal significantly delayed gastric emptying at 2 and 4 hours. You discuss the risks and benefits of lifestyle modification (smaller frequent meals), initiating medications (erythromycin and metoclopramide) or cessation of cannabis (despite low likelihood of CHS). Desiring to avoid starting medications around initiation of pregnancy, she opts for the dietary approach and cessation of cannabis. You see her at a follow-up visit in 6 months, and her nausea is now only once a month, and she is excited to begin planning for a pregnancy using assisted reproductive technology. 

 

Case 4

A 20-year-old nonbinary intersex individual (pronouns: he/they) (incorrectly assigned female at birth — is intersex with congenital adrenal hyperplasia) presents to the gastroenterology clinic with 8 years of heartburn, acid reflux, postprandial bloating, alternating diarrhea and constipation, nausea, and vomiting, complicated by avoidant restrictive food intake disorder. They have a history of bipolar II disorder with prior suicidal ideation. He has not yet had diagnostic workup as he previously had a bad encounter with a gastroenterologist where the gastroenterologist blamed his symptoms on his gender-affirming therapy, misgendered the patient, and told the patient their symptoms were “all in her [sic] head.”

You recognize that affirming their gender and using proper pronouns is the best first way to start rapport and help break the cycle of medicalized trauma. You then recommend a holistic work up with interdisciplinary management because of the complexity of his symptoms. For testing, you recommend a colonoscopy, upper endoscopy, a gastric emptying test with a 48-hour transit scintigraphy test, anorectal manometry, a dietitian referral, and a gastrointestinal psychology referral. Their anorectal manometry is consistent with an evacuation disorder. The rest of the work up is unremarkable. You diagnose them with anorectal pelvic floor dysfunction and functional dyspepsia, recommending biofeedback pelvic floor physical therapy, a proton-pump inhibitor, and neuromodulation in coordination with psychiatry and psychology to start with a plan for follow-up. The patient appreciates you for helping them and listening to their symptoms. 

 

Discussion

When approaching DGBIs in the SGM community, it is vital to validate their concerns and be inclusive with diagnostic and treatment modalities. The diagnostic tools and treatments for DGBI are not different for patients in the SGM community. Like with other patients, trauma-informed care should be utilized, particularly given higher rates of trauma and discrimination in this community. Importantly, their DGBI is not a result of their sexual orientation or gender identity, and hormone therapy is not the cause of their DGBI. Recommending cessation of gender-affirming care or recommending lifestyle measures against their identity is generally not appropriate or necessary. With increased scrutiny being a reality of SGM people’s existence in recent years, cultural humility is needed to establish the rapport necessary to treat DGBIs among members of the SGM communities.
