Treatment of bile leaks from the cystohepatic ducts after laparoscopic cholecystectomy

The cystohepatic ducts represent accessory bile ducts of variable size which frequently travel within the gallbladder fossa or in the posterior wall of the gallbladder. These ducts can be injured during laparoscopic cholecystectomy and can result in bile collections if transected. Successful treatment by operative means or radiologically guided percutaneous drainage is possible, but endoscopic management has several advantages. We describe cases managed by endoscopic retrograde cholangiopancreatography (ERCP) with stent placement and discuss the advantages of this method. Also discussed is the anatomy of these accessory bile ducts, additional management options, and techniques for avoiding this injury during open or closed cholecystectomy.
