Safe Continuation of Glucagon-like Peptide 1 Receptor Agonists at Endoscopy: A Case Series of 57 Adults Undergoing Endoscopic Sleeve Gastroplasty

Abstract

Purpose Glucagon-like receptor agonists (GLP1-RAs) have raised peri-procedural concerns due to their potential to delay gastric emptying. The American Association of Anesthesiologists has advised pausing a single dose before elective endoscopy. However, a subsequent directive from multiple gastroenterology societies underscored the need for further assessment to substantiate this practice. We aimed to evaluate the frequency of serious adverse events and retained gastric products during endoscopic sleeve gastroplasty (ESG) with uninterrupted GLP1-RA use. Materials and methods We conducted a retrospective evaluation of all patients undergoing ESG while on GLP1-RAs at three centers from August 2022 to February 2024. Per standard protocol, all patients had refrained from solid foods for at least 24 h and maintained nil per os for 12 h preceding their ESG. Records were reviewed for patient characteristics and medication type and doses. Primary outcomes included serious adverse events and retained gastric products based on patient records, procedure reports, and procedural videos. Results Fifty-seven consecutive adults (89.5% women, mean age of 44 ± 9 years, mean BMI of 40.1 ± 8.1 kg/m 2 , 35.1% with T2DM, and 26.3% with pre-T2DM) underwent ESG without stopping GLP1-RAs, which included semaglutide (45.6%), liraglutide (19.3%), dulaglutide (22.8%), and tirzepatide (12.3%). During intubation, endoscopy, and recovery, there were no instances of retained gastric solids, pulmonary aspir…
