[The endoscopic treatment of postcholecystectomy biliary leakage]

Although there is a decrease in the total number of complications observed on performance of laparoscopy cholecystectomy (LC) there does appear to be an increase in biliary tract lesions. Seven cases of postcholecystectomy biliary leakage treated with endoscopic methods are presented. These cases include 4 patients with leakage from the cystic canal stump and 3 with leakage from the common bile duct. In 5 cases the biliary tract lesion occurred following LC, 1 after conventional cholecystectomy and in 1 reconverted LP. CPRE identified the site of the leakage in the 7 patients and in 2 residual choledocholithiasis. In 5 cases treatment consisted in endoscopic papillotomy and placement of biliary endoprosthesis while only papillotomy was performed in 2 patients. In one of these cases CPRE was repeated and the sphincterotomy widened due to persistence of the leakage at 5 days, with the same finally closing at 15 days of the second CPRE. Closure of the biliary leakage was obtained in the other 6 cases in less than 72 hours post-CPRE. No complications secondary to the technique were observed. It was concluded that CPRE together with endoscopic papillotomy and placement of biliary prostheses is an effective and safe treatment for postcholecystectomy biliary leakages of the common bile duct or cystic duct.
