The American Gastroenterological Association (AGA) has issued a rapid clinical practice update on the use of glucagon-like peptide 1 (GLP-1) receptor agonists prior to endoscopy.
The update was partly prompted by consensus-based perioperative guidance issued by the American Society of Anesthesiologists in June 2023, which advises withholding GLP-1 receptor agonists before endoscopy. This recommendation has caused some anesthesia providers to cancel or postpone endoscopic procedures, or even elect general endotracheal intubation over standard sedation.
“Many facilities and medical centers are now struggling to revise preprocedural protocols for patients taking this class of medications despite the lack of high-level evidence regarding how to proceed,” the panelists wrote in Clinical Gastroenterology and Hepatology. “Important questions include whether these preprocedural changes are necessary, if they truly mitigate periprocedural aspiration, or if the delays instituted by following this guidance might further compound the major problem currently faced nationwide: that of large numbers of patients awaiting endoscopic procedures because of delays from the COVID-19 pandemic, reduction in the recommended age threshold to start colorectal cancer screening in 2018, and workforce challenges.”
The rapid clinical practice update, commissioned and approved by the AGA, includes background on the relationship between GLP-1 receptor agonists and endoscopic procedures, followed by clinical strategies for patients taking these medications.
Lead panelist Jana G. Al Hashash, MD, MSc, AGAF, of Mayo Clinic, Jacksonville, Florida, and colleagues began by noting that GLP-1 receptor agonists have been associated with increased gastric residue in patients with diabetes, and among nondiabetic patients, increased gastric retention of solids but not liquids. Delayed gastric emptying and increased residual gastric contents may be more common among patients on GLP-1 agonists who have vomiting, nausea, dyspepsia, or abdominal bloating, they added.
The above findings “imply an increased risk of aspiration in patients receiving GLP-1 receptor agonist medications who present for procedures that require sedation,” the panelists wrote, but more data is needed to support this hypothesis.
Yet the implications for endoscopic risk are still unclear.
Residual liquid in the stomach, at least, is “less of an issue,” according to the update, since “it is easily removed during an esophagogastroduodenoscopy, and this is the first maneuver performed by endoscopists on entering the stomach.”
While residual solids in the stomach could theoretically increase risk of aspiration, other patients with gastroparesis, such as those taking opioids, are not routinely given “special dietary precautions or medication adjustments” prior to endoscopy, Dr. Al Hashash and colleagues wrote. Even patients with severe gastroparesis who are undergoing gastric peroral endoscopic myotomy (which depends upon an empty stomach), are only required to stop ingesting solid foods the day before the procedure, they noted.
“It is appropriate that the ASA’s perioperative suggestions for patients on GLP-1 [receptor agonists] are labeled ‘consensus-based guidance on perioperative management,’ because there is clearly insufficient published evidence for a robust systematic review and guideline,” they wrote. “As such, the ASA’s suggestions are expert opinions, which may inform but should not replace clinical judgment.”
, for whom withholding these medications “might provide more risk than benefit.”
Withholding GLP-1 receptor agonists may be safe and reasonable for patients taking them solely for weight loss, but “this should not be considered mandatory or evidence-based,” as it remains unclear whether withholding one dose is enough to restore normal gastric motility.
“Generally, in patients on GLP-1 receptor agonists who have followed standard perioperative procedures (typically an 8-hour solid-food fast and a 2-hour liquid fast) and who do not have symptoms of nausea, vomiting, dyspepsia, or abdominal distention, we advise proceeding with upper and/or lower endoscopy,” the panelists concluded.
The rapid clinical practice update was commissioned and approved by the AGA. The update panelists disclosed relationships with Apollo Endosurgery, Medtronic, Boston Scientific, and others.
