Objective To study the efficacy of endoscopic retrograde cholangio-pancreatography (ERCP) and endoscopic nasobiliary drainage (ENBD) in the diagnosis and treatment of bile leakage after laparoscopic cholecystectomy (LC).Methods The clinical data of 9 patients with bile leakage after LC were analyzed retrospectively.Results The procedure of ERCP was successful in all 9 patients.Bile leakage was treated successfully by ENBD in 8 patients with no further complication,and 1 patient was treated surgically because of biliary ductal injury.Conclusions ERCP is recommended as a safe and efficacious option to detect and treat bile leakage after LC.ENBD combined with percutaneous drainage of abdominal collections can cure bile leakage after LC.
