[Cholecystic fistula with atypical symptoms].

We report a patient with spontaneous cholecystocolonis fistula secondary to cholelithiasis. A 93 year-old woman was admitted because of weight loss, diarrhoea and upper abdominal pain. Ultrasound examination revealed air in the biliary tract and cholescientigraphy revealed a fistula between the gallbladder and right colon. Using endoscopic retrograde cholangiopancreatography a calculus was extracted from the bile duct and the symptoms disappeared.
