Safety and efficacy of endoscopic ultrasound‐guided gallbladder drainage combined with endoscopic retrograde cholangiopancreatography in the same session

Abstract

BACKGROUND AND AIM: Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is an emerging option for acute cholecystitis in non-surgical candidates. Combining endoscopic retrograde cholangiopancreatography (ERCP) for common bile duct stones with EUS-GBD in a single session might become a non-surgical management strategy to comprehensively treat gallstone disease in selected patients. METHODS: Single-center retrospective cohort study comparing outcomes between EUS-GBD alone (group A) and single-session ERCP combined with EUS-GBD (group B). Consecutive patients who underwent EUS-GBD with a lumen-apposing metal stent (LAMS) between June 2011 and August 2018 were analyzed. Exclusion criteria were subjects included in randomized clinical trials, patients who had had ERCP within 5 days of EUS-GBD, patients in whom ERCP or EUS-GBD was carried out for salvage of one or the other procedure, and patients who underwent concurrent EUS-guided biliary drainage. RESULTS: One hundred and nine consecutive patients underwent EUS-GBD with LAMS during the study period. Seventy-one patients satisfied the inclusion criteria and 34 patients were in group A and 37 in group B. Baseline characteristics were similar in both groups. There were no significant differences in technical (97.1% vs 97.3%; P = 0.19) and clinical success rates (88.2% vs 94.6%; P = 0.42) of EUS-GBD in group A versus group B. Rate of adverse events was similar in both groups, five (14.7%) in group A versus five (13.5%) in group B. CONCLUSIONS: Single-session EUS-GBD combined with ERCP has comparable rates of technical and clinical success to EUS-GBD alone. A combined EUS-GBD and ERCP procedure does not appear to increase adverse events and makes possible comprehensive treatment of gallstone disease by purely endoscopic means.
