Long-term Outcomes of Elective EUS-guided Gallbladder Drainage After Percutaneous Transhepatic Gallbladder Drainage

BackgroundEndoscopic ultrasound (EUS)-guided gallbladder drainage (GBD) has gained increasing popularity as an alternative treatment approach for acute cholecystitis in high-risk patients. We report the procedural and long-term outcomes of elective EUS-GBD using self-expandable metallic stents (SEMSs) after percutaneous transhepatic (PTGBD) cholecystitis.MethodsBetween April 2015 January 2017, 15 patients at study institution underwent PTGBD. SEMSs were placed all patients, external catheter was removed one week procedure. Procedural measured retrospectively.ResultsBoth technical clinical success rates 93.3% (14/15). Two (13.3%) developed adverse events, with distal stent migration patient (6.7%) asymptomatic pneumoperitoneum other (6.7%). Cholecystitis recurred only who experienced migration. None cholecystectomy. The median duration patency 544 days (18-1006 days), without any deaths. overall rate 86.7% (13/15).ConclusionThus, PTGBD exhibited favorable outcomes, indicating that this is effective severe comorbidities preclude open surgical
