Abstract
Objective To evaluate the therapeutic effect and safety of forward-viewing, double- channel endoscope in the process of ERCP in patients with bile duct diseases after Billroth- Ⅱ gastroenteros- tomy. Methods ERCP was applied to 46 patients with bile duct diseases using forward-viewing, double- channel endoscope. All patients had the history of BiUroth- Ⅱ gastroenterostomy. The success rate of selec- tive cannulation, complication rate and the outcome of all the patients were recorded. Results The proce- dure succeeded in 38 patients with a success rate of 82. 6%, and failed in 8. Of all the failing cases, the af- ferent loop couldn＇t be accessed in 6, failure in biliary cannulation in 2. Of 38 successful cases, bile duct stones were successfully removed in 31, metal stents placed for malignant bile duct obstruction in 4, and en- doscopic balloon dilation for benign common bile duct stricture in 3. All patients recovered without complica- tions of perforation, delayed bleeding or pancreatitis. Conclusion For patients with history of Billroth- Ⅱ gastroenterostomy, ERCP with forward-viewing, double-channel endoscope yields to a higher success rate and lower complication rate. Key words: Cholangiopancreatography, endoscopic retrograde; BiUroth- Ⅱ gastroenterostomy; Double-channel endoscope
