Significance of bile leaks complicating conservative surgery for liver hydatidosis.

Abstract

Hepatic hydatidosis presents a challenge in liver surgery, and there is still controversy regarding the appropriate surgical technique. A high incidence of postoperative bile leaks is reported as a significant disadvantage of conservative surgical procedures. The purpose of this study was to examine the incidence and clinical importance of bile leakage in patients being treated exclusively by a conservative surgical technique. From January 1985 to November 2000 a total of 187 patients were operated on at our department for hepatic hydatidosis. They were subjected to the standard conservative surgical technique (wide unroofing and cyst drainage). A total of 18 complications were related to bile leakage (10%), 3 of them bile abscesses (1 drained surgically and 2 percutaneously), 1 case of bile peritonitis due to an accessory bile duct in the gallbladder bed (treated surgically), and 14 fistulas (1 bronchobiliary and 13 biliocutaneous). Five of the fistulas, including the bronchobiliary one, were treated successfully by endoscopy; and the remaining nine healed after conservative treatment. Bile leakage, representing a significant complication following conservative operations for hepatic hydatidosis, can be effectively treated conservatively or endoscopically, not justifying more aggressive surgical approaches.
