A Rare Case of Cholecystoduodenal and Cholecystocolic Fistula with Gallstone Ileus.

Cholecystoduodenal and cholecystocolic fistula (CCF) is a rare condition, occurring in patients with cholelithiasis. Multiple complex fistulas are even rare. This is a case study done to detail such a rare case, very few such cases have been reported in the past studies, with cholecystoduodenal and CCF with gallstone ileus. We present the case of an 80-year-old, female diagnosed with intestinal obstruction. Intraoperatively, the gallbladder (GB) fundus forms a CCF and the body of the GB with the first part of the duodenum forms cholecystoduodenal fistula. Gallstone ileus found impacted in jejunum 35 cm distal to DJ junction. Resection of fistula tracts with primary repair of the transverse colon was done with Graham's patch repair of duodenum and fundus first cholecystectomy. Cholecysto-duodeno-colic fistulas complicated with gallstone ileus are very rare. In the case of gallstone ileus, the surgical treatment is an emergency and the only therapeutic option.
