    Abstract:
    Biliary leaks and injuries are not an uncommon occurrence following laparoscopic cholecystectomy. Bile leaks associated with the biliary anatomic variant of a low-inserting right segmental hepatic duct can be particularly difficult to diagnose in that results of endoscopic retrograde cholangiography (ERC) are usually interpreted as "normal" with no leaks demonstrated. The aim of this study was to describe a single institution's experience with nine patients with biliary leaks associated with this anatomic variant and to discuss their management. A retrospective analysis of the hospital records of all patients with bile duct injuries managed at a single institution between 1980 and July 1998, inclusive, was performed. Nine patients were identified as having an isolated right segmental hepatic duct injury associated with a biliary leak. Seven (78%) of the nine patients had undergone a laparoscopic cholecystectomy, whereas the remaining two patients (22%) had undergone an open cholecystectomy. All of the patients had undergone endoscopic retrograde cholangiography at outside institutions, the results of which had been interpreted as normal with no apparent leaks. The median interval from the time of cholecystectomy to referral was 1.4 months. All patients were managed with initial percutaneous access of the involved right segmental biliary system, with placement of a percutaneous transhepatic stent. After the biliary leak was controlled, all patients underwent Roux-en-Y hepaticojejunostomy to the isolated biliary segment. All patients had an uncomplicated postoperative course. There were no postoperative anastomotic leaks. Postoperative stenting was maintained for a mean of 8 months. Six (67%) of the nine patients had a long-term successful outcome with minimal or no symptoms. In three patients, recurrent symptoms with pain and/or cholangitis developed at a mean of 34 months. All three patients underwent percutaneous cholangiography, which demonstrated an anastomotic stricture, and all were managed with percutaneous balloon dilatation with a successful outcome. Currently eight (89%) of the nine patients are asymptomatic, with a mean follow-up of 70.4 months (range 12 to 226 months). One patient had intermittent right upper quadrant pain with normal liver function tests but has not required intervention. Isolated right segmental hepatic ductal injury with biliary leakage is an uncommon complication following laparoscopic cholecystectomy. A diagnostic dilemma is created by the presence of a bile leak with a normal endoscopic retrograde cholangiogram. Management begins with percutaneous access of the transected isolated ductal system followed by reconstruction as a Roux-en-Y hepaticojejunostomy.
