BACKGROUND/AIMS: Endoscopic treatment of biliary leakages after cholecystectomy, though widely accepted, has some restrictions. The efficacy and safety of endoscopic treatments in this patient group are evaluated in this study, and the problem of biliary stricture development in time after biliary ductal injuries is also emphasized. METHODS: Seventy-four patients (20 male, 54 female, mean age 50.9+/-21 years) referred for ERCP between 1992-2002 were included in the study. Minor leakages (cystic duct leaks, accessory bile duct leaks) were managed by nasobiliary drainage +/- endoscopic sphincterotomy; major leakages were managed by nasobiliary drainage +/- endoscopic sphincterotomy +/- stenting. RESULTS: Twenty-seven patients with cystic duct leaks and 6 patients with accessory bile duct leaks were successfully treated with nasobiliary drainage. Endoscopic treatment could not be performed on patients with total bile duct obstruction (7 patients) and aberrant bile duct injury (7 patients). All leakages from main bile ducts were closed (27 patients). Six of 27 patients had strictures at the beginning and they were treated by stenting. Twenty-one patients had no strictures at the beginning. Eight of 21 were treated by stenting and only 1 of them developed biliary stricture. Seven of 13 patients who had been treated by nasobiliary drainage developed biliary strictures. There were no mortalities due to procedure. CONCLUSIONS: ERCP is an effective and safe method for diagnosis and management of bile leakages after cholecystectomy. Stricture development in the main bile duct leakages was an important complication.
