RESULTS OF ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY COMBINED WITH SPHINCTEROTOMY IN TREATMENT OF COMMON BILE DUCT STONES

Background: Common bile duct stone is the popular disease which leads to more severe complication. Endoscopic retrograde cholangiopancreatography is a useful therapy in treatment of common bile duct stone. However, the success of this therapy must depend on several specific impacts including the number of stones, stone diameter, diverticulum and endoscopist. Thus, we have performed this research on two major purposes: 1) to evaluate the results and complication of ERCP in treatment of common bile duct stone; and 2) to determine the influential factors causing failure of this therapy. Patients/Research methods: A total of 64 patients are involved in the treatment at the gastrointestinal endoscopic center. Methods: A cross - sectional study. Result: CBD stone with size from 10 – 20mm makes up the highest proportion of 76.7%. A single stone makes up for the large proportion at 68.7%. The successful rate of CBD is 89.1%. The rate of complication is 10.9%. The influential factor for failure of ERCP: The patients undergoing operation have diverticulum and large stone. Conclusion: ERCP is an effective and safe therapy for treatment CDB stone. Key words: Common bile duct stone, endoscopic retrograde cholangiopancreatography.
