Wear N95 masks during endoscopy

Nausea, vomiting, and diarrhea are gastrointestinal symptoms that COVID-19 patients have had, and up to 30% have been reported to have liver symptoms. Because patients with these symptoms may require endoscopy, the American Gastroenterological Association has issued a rapid recommendation document that advises physicians and health care workers to use N95 masks, double gloves, and negative-pressure rooms when performing GI procedures during the COVID-19 pandemic.

The recommendations, published in Gastroenterology (2020. doi: 10.1053/j.gastro.2020.03.072), also cover non–COVID-19 patients and situations where N95 masks should be used, offer guidelines for triaging patients for endoscopy and timing of nonurgent procedures, and evaluate the latest evidence in the incidence of GI and liver manifestations of COVID-19. The guideline panel met in March.

The document includes seven recommendations for use of personal protective equipment by physicians and nurses performing GI procedures. The recommendations and the level of evidence supporting them fall under four categories:

1. Masks, comprising four recommendations: use of N95 masks for upper and lower GI procedures regardless of a patient’s COVID-19 status; no use of only surgical masks in confirmed COVID-19 patients or suspected cases; and use of reused N95 masks when fresh ones aren’t available instead of using a surgical mask only (very low to moderate level of evidence depending on the recommendation).

2. Double-gloving when performing any GI procedure regardless of the patient’s COVID-19 status (moderate quality evidence).

3. When available, a negative-pressure room for any COVID-19 patient or suspect rather than a regular endoscopy room (very low certainty of evidence).

4. Standard cleaning, endoscopic disinfection, and reprocessing protocols regardless of a patient’s COVID-19 status (good practice statement).

For decontamination, the panel noted that commonly used biocidal agents, such as hydrogen peroxide, alcohols, sodium hypochlorite, or benzalkonium chloride have proved effective for decontaminating of coronavirus.

For implementing the PPE recommendations, the panel stated that personnel still need to practice don and doff standard protocols, and that N95 masks should be fitted for each individual.

Other steps include banning personal belongings in the procedure area; minimizing the number of personnel in the room; avoiding change of personnel and keeping nonprocedural personnel out during the procedure; considering use of nursing teams that follow the patient through preprocedure, procedure, and recovery, and considering having endoscopy teams remain together during the day to minimize exposure.

The triage recommendations stated that “trained medical personnel” should review all procedures and categorize them as time-sensitive or not time-sensitive, based on a framework the recommendation includes. In “an open-access endoscopy system” when there isn’t enough information to determine timing for the procedure, the recommendation provides a three-step approach: a phone consult with the referring physician, a telehealth visit with the patient, or a multidisciplinary team approach or virtual disease/tumor board.

“The proposed framework of separating procedures into time-sensitive and non–time-sensitive cases may be useful in determining which procedures if delayed may negatively impact on patient-important outcomes,” wrote Shahnaz Sultan, MD, AGAF, of the University of Minnesota, Minneapolis, and colleagues. The panel noted decision-making should focus on “patient-important outcomes.”

For nonurgent procedures, the panel arrived at a consensus that 8 weeks was an appropriate window for reassessment of deferred procedures, depending on the availability of resources and if the time-sensitivity of the procedure changes.

The panel also attempted to determine the likelihood of GI and liver manifestations of COVID-19 by evaluating published cohort studies. They found that 2%-13.8% of patients had diarrhea, 1%-10.1% had nausea or vomiting, and one study reported 2% had abdominal pain (Am J Gastroenterol. 2020 May;115[5]766-73). What’s more, some studies have shown stool samples positive for SARS-CoV-2 RNA even after respiratory samples were negative.

The evidence on liver manifestations isn’t as robust, but one study reported that 20%-30% of patients had liver injury upon diagnosis of COVID-19 (Gastroenterology. 2020;158:1518-9), and that severe hepatitis has been reported but liver failure seems rare (Lancet. 2020 Feb 15;395[10223]:507-13). “The pattern of liver injury appears to be predominantly hepatocellular, and the etiology remains uncertain but may represent a secondary effect of the systemic inflammatory response observed with COVID-19 disease, although direct viral infection and drug-induced liver injury cannot be excluded,” Dr. Sultan and colleagues noted.

There were no relevant author conflicts of interest. The American Gastroenterological Association (AGA) Institute funded the study.
