Perforated emphysematous cholecystitis managed by endoscopic transpapillary gallbladder drainage.

An 88-year-old woman with dementia was diagnosed as having perforated emphysematous cholecystitis with localized peritonitis. Because she was at high risk for surgery, gallbladder drainage was required before surgery. Endoscopic transpapillary gallbladder drainage instead of percutaneous transhepatic biliary drainage was performed because bile could leak from the puncture site to free space around the perforated gallbladder. After the insertion of a nasobiliary drainage tube, the gallbladder was drained and cleaned with saline solution. Subsequently, a nasobiliary drainage tube was replaced with a double-pigtail stent because she was at high risk of dislodging the nasobiliary drainage tube. Although clinical improvement was observed, she was treated conservatively without surgery. She was followed up for 6 months without developing cholecystitis. For perforated cholecystitis without developing panperitonitis, endoscopic transpapillary gallbladder drainage would be an effective option as a bridge to surgery for the initial treatment and as an alternative to surgery for long-term management for a later treatment. This is the first reported case of perforated emphysematous cholecystitis with localized peritonitis treated with endoscopic transpapillary gallbladder drainage.
