How to treat remnant cholecystitis after subtotal cholecystectomy: two case reports.

backgroundSubtotal cholecystectomy in patients with severe acute cholecystitis is considered a "bailout" option when the safety of the bile duct cannot be guaranteed. However, subtotal cholecystectomy has a long-term risk of remnant cholecystitis. The appropriate management of remnant cholecystitis has not been fully elucidated. CASE PRESENTATION: Case 1 was a 66-year-old man who had undergone subtotal cholecystectomy 14 years prior to the development of remnant cholecystitis. We first performed endoscopic gallbladder drainage to minimize inflammation, and then proceeded with elective surgery. We performed a reconstituting procedure for the residual gallbladder due to significant adhesions between the cystic and common bile ducts. Case 2 was a 56-year-old man who had undergone subtotal cholecystectomy for abscess-forming perforated cholecystitis 2 years prior to the development of remnant cholecystitis. He underwent endoscopic drainage followed by complete remnant cholecystectomy 4 months later.

conclusionEndoscopic gallbladder drainage is a useful strategy to improve inflammation and reduce the risk of bile duct injury during remnant cholecystectomy.
