[Biliary-colonic fistulas. Analysis of 2 cases and literature review].

BACKGROUND

Bilioenteric fistulas are entities whose etiology can be diverse.

OBJECTIVE

The aim of this paper was to present two cases of biliary-colonic fistulas with different presentations and to review existing literature regarding etiology, diagnosis, and management of these patients.

METHODS

Two cases of biliary-colonic fistulas were reviewed.

RESULTS

Case 1. A 48-year-old woman presented with lower gastrointestinal bleeding secondary to cholecystocolonic fistula in context of cholelithiasis. Case 2. A 60-year-old woman with multiple hepatic abscess associated with biliary-colonic fistula secondary to adenocarcinoma of gallbladder.

CONCLUSIONS

Biliary-colonic fistulas are recognized complications of cholelithiasis. Association with neoplasia is less frequent. Preoperative diagnosis is difficult and management must be surgical.
