Application of endoscopic retrograde cholangiopancreatography in treatment of extrahepatic biliary adenoma

Objective To investigate the clinical features of extrahepatic biliary adenoma and the role of endoscopic retrograde cholangiopancreatography( ERCP) in the diagnosis and treatment of extrahepatic biliary adenoma. Methods A retrospective analysis was performed for the clinical manifestations,imaging findings,ERCP treatment,and follow- up data of 7 patients with extrahepatic biliary adenoma who were admitted to Department of Gastroenterology in The People's Hospital of Northern Jiangsu from January 2010 to June 2016. Results Selective ERCP was performed for 7 patients after the exclusion of surgical contraindications. Intraoperative cholangiography showed interruption of different parts of the bile duct,and brush cytology under the guidance of guide wire and bile duct biopsy with ultrafine biopsy forceps were performed for all patients. The pathological examination showed bile duct adenoma. Among these patients,6 were treated with ERCP and 1 was treated with Roux- en- Y choledochojejunostomy after ERCP. Conclusion As a minimally invasive examination,ERCP helps to determine the cause of the disease and evaluate patients' condition. When patients have surgical contraindications or are not willing to choose surgery,ERCP can be used as palliative therapy to relieve their clinical symptoms.
