Abstract:
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.
