Ruptured cystic artery pseudoaneurysm after long-term transpapillary placement of a gallbladder stent for acute cholecystitis.

Abstract

Endoscopic transpapillary gallbladder drainage (ETGBD), including endoscopic gallbladder stenting (EGBS), has utility in the management of acute cholecystitis in patients considered to be high risk candidates for surgery [1]. A recent meta-analysis reported that the pooled rate of cholecystitis recurrence was 4.6 % following ETGBD in patients with acute cholecystitis [2]. Long-term biliary drainage via EGBS is often performed to prevent the recurrence of cholecystitis in patients with contraindications to cholecystectomy.
