title: Laparoscopic management of gallstone presenting as obstructive gangrenous appendicitis.
abstract: We present an unusual case of a 55-year-old man with symptoms of recurrent appendicitis. Laparoscopy revealed a 1.5 cm gallstone impacted at the base of the appendix, leading to gangrenous appendicitis. This patient did not have any features of gallstone ileus. On imaging he had an inflammatory mass in the region of the right iliac fossa with a hyperintense shadow in the cecal area which was reported as an appendicolith. There was no demonstrable cholelithiasis or biliary-enteric fistula. There were dense omental adhesions in the pericholecystic area on laparoscopy. The case was successfully managed by laparoscopic appendectomy with retrieval of the gallstone. No surgery was undertaken for the gallbladder. Diagnosis was confirmed by biochemical analysis of the stone, which contained calcium bilirubinate and cholesterol. A gallstone obstructing the appendicular lumen is a very rare etiology of gangrenous perforation of the appendix peritonitis. This case was successfully managed laparoscopically.
