Benefits of endoscopic drainage for external bile leakage after cholecystectomy

We reported the benefits of Endoscopic Nasobiliary Drainage (ENBD) for external bile leakage after cholecystectomy. We performed ENBD in seven patients with postoperative bile leakage. Six of seven patients (85.7%) were successfully treated within 10days. One patient was failed to be cannulated into common bile duct and repeat surgery was performed. We could evaluate successful drainage from a point of view of the bile volume of the leakage and ENBD during the first two days. It is useful that the side hole at the tip of drainage tube is placed at the proximal of the fistula. ENBD is considerd the first choice of treatment for external bile leakage after cholecystectomy.
