[Diagnostic and therapeutic endoscopic cholangiopancreatography in biliary leak after liver transplantation. Report of 2 cases].

Background: The most common biliary tract complications after orthotopic liver transplantation are anastomotic strictures and bile leaks. These remain important causes of morbidity, frequently prompting surgical approach and/or biliary drainage.

Objective: To report our experience using endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis and management of biliary tract complications in patients with hepatic transplantation.

Patients/methods And Results: We present two patients with hepatic transplantation who developed bile peritonitis secondary to biliary leaks diagnosed by ERCP, both treated with sphincterotomy and biliary endoprostheses. Bile leaks rapidly resolved after endoscopic sphincterotomy and stent placement.

Conclusions: ERCP is a useful diagnostic and therapeutic intervention for post-transplantation biliary tract complications.
