Surgical therapy of iatrogenic lesions of biliary tract.

Iatrogenic injuries of the biliary tract have increased in incidence over the past decade with the introduction of laparoscopic cholecystectomy. Although a number of factors have been identified with a higher risk of injury (male gender, complicated gallstone disease, aberrant anatomy) and a number of technical steps have been emphasized to avoid these injuries, the incidence of bile duct injuries has reached a steady-state at least double the rate observed with open cholecystectomy. Most patients sustaining a bile duct injury are recognized in the weeks following laparoscopic cholecystectomy. Careful preoperative preparation should include control of sepsis by draining any bile collections or fistulas and complete cholangiography. Long-term results are best achieved in specialized hepatobiliary centers performing biliary reconstruction with a Roux-en-Y hepaticojejunostomy. Success rates over 90% have been reported from several centers to date with intermediate follow-up.
