Thinking ahead: gallbladder intussusception following transperitoneal percutaneous cholecystostomy tube placement.

Percutaneous cholecystostomy (PC) is a common minimally invasive, image-guided procedure performed primarily on high-risk patients with acute cholecystitis for gallbladder decompression. Herein, we present a case of a patient undergoing PC placement using a transperitoneal approach. On subsequent upsizing attempts, the gallbladder fundus was found to invaginate during advancement of replacement drains, causing gallbladder intussusception.
