Bile leak from the accessory biliary duct following laparascopic cholecystectomy

Anatomists and surgeons have described the presence of accessory biliary ducts between the liver and gallbladder. Bile leakage from accessory duct following laparoscopic cholecystectomy (LC) is an unusual post-operative complication. Aim of the study was to assess its incidence, the intraoperative methods helpful for notice the anatomical anomaly and the impact of endoscopic procedure as a suitable treatment. From January 1997 to September 2002, 185 patients underwent LC for symptomatic cholelithiasis in our surgical department. Post-operative bile leakage from accessory biliary duct occurred in two patients (1%): one case from the liver bed of gallbladder (duct of Luschka) and one case from an aberrant cholecystohepatic duct entering Hartmann's pouch. One patient underwent open celiotomy because of unavailability of endoscopic retrograde cholangiopancreatography. The other patient was successfully treated by endoscopic sphincterotomy and nasobiliary tube placement. By careful dissection, accessory ducts were noticed and clipped in three other patients with overall incidence of 2.7%. Meticulous laparoscopic technique aimed to careful recognize all structures during LC is the main policy to contain biliary injury within its nadir incidence. Depending of availability, endoscopic sphincterotomy and nasobiliary drainage allow diagnosis and treatment of bile leakage, preserving the effectiveness of laparoscopic procedure.
