[A case of gallstone ileus which the cholecystoduodenal fistula closed spontaneously after laparoscopic-assisted simple enterolithotomy].

A 47-year-old woman complaining of diarrhea and vomiting was admitted on the suspicion of gallstone ileus 4 days after onset. Upper gastrointestinal radiography by Gastrografin showed a cholecystoduodenal fistula. Laparoscopic-assisted simple enterolithotomy was performed. The omentum was severely adherent to the gall bladder and fistula, though biliary surgery was not performed. Without second look operation, for cholecystoduodenal fistula closed spontaneously.
