Endoscopic treatment of postoperative biliary fistulas.

Background: Biliary fistula is one of the most common complications of liver and biliary tract surgeries. Endoscopic retrograde cholangiopancreatography (ERCP) is used for the diagnosis and treatment of biliary fistulas. In this study, we aimed to analyze the contribution of ERCP in this regard.

Methods: Patients who underwent ERCP for biliary fistulas following liver and biliary tract surgery between January 2012 and December 2017 were included in this study. The demographic characteristics of the patient, surgical procedure, localization of the biliary fistula, classification of biliary duct injury, and success of ERCP were retrospectively evaluated.

Results: In total, 90 patients (37 male and 53 female) with a diagnosis of biliary fistula underwent ERCP. Common biliary duct (CBD) cannulation was achieved in 87 patients using ERCP. In five patients, the proximal part of the biliary tract was not visualized, and complete injury of CBD was considered. In ERCP, contrast extravasation was detected in the cystic duct in 44 patients: CBD, eight patients; liver bed, four patients; hepatic duct bifurcation, two patients; the right hepatic canal, seven patients; and the left hepatic canal, two patients.

Conclusion: ERCP is an effective method for the diagnosis and treatment of biliary diseases. The diagnosis and treatment of postoperative biliary fistulas with ERCP reduces surgery cost, morbidity, and mortality.
