A case of gallstone ileus of colon with cholecystcolic fistula

Abstract

A gallstone ileus with cholecystocolic fistula is very rare. An 81-year-old woman was introduced to our hospital for gallstone ileus. She was admitted to the previous hospital, complaining of vomit and abdominal pain. An abdominal CT showed ileus and a gallstone in the sigmoid colon. Transanal discharge was expected, but the stone was not defecated and she was introduced to our hospital for operation. Cholecystotransversecolic fistula and impacted gallstone in sigmoid colon were confirmed. We performed cholecystectomy, closure of fistula, partial sigmoidectomy, and colostomy. Her postoperative course was uneventful. We report this rare case with review of the literature.
