Biliary Colon: A Rare Cholelithiasis complication

Abstract

Cholecystocolic fistula is a rare complication of biliary lithiasis. Clinical presentation is variable and nonspecific.
The authors describe a clinical case of a patient with low mechanical obstruction caused by impaction in the sigmoid colon of a gallstone from a cholecystolic fistula.
In view of the unsuccessful attempt to remove the calculus through colonoscopy, a laparotomy, with enterotomy was performed after mobilization of the calculus and removal of the calculation and lateral colostomy, without intraoperative complications.
The choice of the surgical technique and the prognosis are inevitably conditioned by the general state and associated co-morbidities.
