Abstract
Background and study aims
We investigated the effect of semaglutide, a glucagon-like peptide-1 (GLP-1) agonist therapy, on retained gastric contents during endoscopy through a retrospective case-control study.
Patients and methods
We performed a retrospective case-control study to evaluate the effect of semaglutide on rates of retained gastric contents (RGC) visualized during esophagogastroduodenoscopy (EGD). Cases and controls were matched using multidimensional propensity score matching: age, gender, body mass index, and EGD indication. Pairs were analyzed using McNemar testing and Mann-Whitney non-parametric tests.
Results
Of the patients on GLP-1 therapy at time of EGD, 12.5% had RGC, compared with 1.3% in the control group (confidence interval [CI] 7.2% to 17.7%, P < 0.0001). Approximately 23% of patients prescribed GLP-1 therapy for weight loss had RGC at time of EGD compared with the control group (CI 13.4% to 32.6%, P < 0.0001). Only 2.6% of patients prescribed GLP-1 therapy for diabetes had RGC at time of EGD compared with the control group (CI -0.9% to 6.1%, P = 0.5). Patients receiving GLP-1 therapy with RGC at time of EGD did not differ from non-RGC patients in dosing of GLP-1 agonist (P = 0.23) or duration of GLP-1 agonist use prior to EGD (P = 0.98).
Conclusions
Semaglutide use appears to increase risk of having retained gastric contents visualized during endoscopy. Patients on semaglutide for weight loss appear to have a greater risk of RGC compared with patients on semaglutide for glycemic control. This observation may have clinical implications for management of GLP-1 agonist use prior to endoscopy.
