Summary Esophageal high-resolution manometry (HRM) is the gold standard for evaluating esophageal motility disorders but can be limited by patient intolerance. With increasing use of glucagon-like peptide-1 receptor agonists (GLP-1RAs) for obesity and type 2 diabetes, delayed gastric emptying raises concerns for HRM feasibility and safety. This study assessed HRM tolerability in patients on GLP-1RAs. We conducted a retrospective case–control study of adult patients who underwent HRM at our tertiary care center between January 2014 and November 2024. Patients actively taking GLP-1RAs during HRM were identified as cases, while an equal number of consecutive eligible patients not on GLP-1RAs served as controls. Patients with established gastrointestinal dysmotility, prior foregut surgery, esophageal mechanical obstruction, large hiatal hernias, malignancy, or recent opioid use were excluded. From a prospective database of 7194 HRM attempts, 83 cases and 83 matched controls were identified. Among 166 patients, 15 (9.0%) had incomplete HRM due to intolerance, with similar rates between GLP-1RA users and controls (10.84% vs. 7.2%, P = 0.59). Predictors of incomplete HRM included younger age (44.9 ± 17.4 vs. 60.4 ± 13.7 years, P < 0.01), globus (P = 0.02), dyspepsia (P = 0.02), and depression (P = 0.04). No aspiration or adverse events occurred in either group. Duration of HRM before abortion was similar between cases and controls. GLP-1RA use was not associated with increased risk of HRM abortion or adverse events, suggesting these medications do not significantly impact HRM feasibility or safety.

Purpose of review Metabolic and bariatric surgery (MBS) and endoscopic bariatric therapies (EBT) are being increasingly utilized for the management of obesity. They work through multiple mechanisms, including restriction, malabsorption, and changes in the gastrointestinal hormonal and motility. Recent findings Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) cause decrease in leptin, increase in GLP-1 and PYY, and variable changes in ghrelin (generally thought to decrease). RYGB and LSG lead to rapid gastric emptying, increase in small bowel motility, and possible decrease in colonic motility. Endoscopic sleeve gastroplasty (ESG) causes decrease in leptin and increase in GLP-1, ghrelin, and PYY; and delayed gastric motility. Summary Understanding mechanisms of action for MBS and EBT is critical for optimal care of patients and will help in further refinement of these interventions.

Abstract Background and study aims Endoscopic sleeve gastroplasty (ESG) is performed in clinical practice by gastroenterologists and bariatric surgeons. Given the increasing regulatory approval and global adoption, we aimed to evaluate real-world outcomes in multidisciplinary practices involving bariatric surgeons and gastroenterologists across the United States. Patients and methods We included adult patients with obesity who underwent ESG from January 2013 to August 2022 in seven academic and private centers in the United States. Patient and procedure characteristics, serious adverse events (SAEs), and weight loss outcomes up to 24 months were analyzed. SPSS (version 29.0) was used for all statistical analyses. Results A total of 1506 patients from seven sites included 235 (15.6%) treated by surgeons and 1271 (84.4%) treated by gastroenterologists. There were no baseline differences between groups. Gastroenterologists used argon plasma coagulation for marking significantly more often than surgeons (P<0.001). Surgeons placed sutures in the fundus in all instances whereas gastroenterologist placed them in the fundus in less than 1% of the cases (P<0.001>). Procedure times were significantly different between groups, with surgeons requiring approximately 20 minutes more during the procedure than gastroenterologists (P<0.001). Percent total body weight loss (%TBWL) and percent responders achieving >10 and >15% TBWL were similar between the two groups at 12, 18, and 24 months. Rates of SAEs were low and similar at 1.7% for surgeons and 2.7% for gastroenterologists (P>0.05). Conclusions Data from a large US cohort show significant and sustained weight loss with ESG and an excellent safety profile in both bariatric surgery and gastroenterology practices, supporting the scalability of the procedure across practices in a multidisciplinary setting.

Goals: We aim to describe the weight loss outcomes of patients with celiac disease (CeD) taking antiobesity medications (AOMs) and compare it with the weight loss outcomes of patients without CeD taking AOMs. Background: Increasing rates of obesity and obesity-associated comorbidities have been previously reported in patients with CeD on a gluten-free diet. The effectiveness of AOMs in this population has not been previously described. Methods: In our retrospective cohort study, we matched 39 patients with treated CeD to 78 patients without CeD based on sex and AOM. We assessed the weight loss outcomes at 3, 6, and 12 months after starting the AOM in both cohorts and analyzed if there was a differential response when comparing by type of AOM [injectable glucagon-like peptide 1 (GLP-1) receptor agonists vs. oral non-GLP-1 AOMs]. Results: Both cohorts had similar baseline demographic and anthropometric characteristics. At 12 months, the CeD cohort had a nonsignificantly inferior total body weight loss percentage compared with the cohort without CeD (6.5% vs. 9.5%, P=0.13). The CeD cohort had a similar proportion of patients achieving a total body weight loss percentage of ≥5% than the cohort without CeD (72.7% vs. 72.1%, P=1.00). No significant difference was observed when comparing the weight loss outcomes of injectables (GLP-1 receptor agonists) to oral AOMs. The proportion of patients reporting side effects was similar for both groups, regardless of the type of AOM. Conclusion: Patients with CeD taking AOMs had similar weight loss outcomes to patients without CeD. Hence, AOMs can be a safe and effective therapy for weight management in patients with CeD.
