Management of postoperative bile leakage with endoscopic sphincterotomy (EST) and a naso-biliary drain (NBD)

Abstract

Between July 1987 and December 1990, 13 patients with postoperative bile leakage were treated with endoscopic sphincterotomy and a naso-biliary drain. All the leaks healed in two weeks, except for one (intrahepatic) that needed two months to heal in association with percutaneous management. The non-surgical treatment of bile leakage is the preferred approach on account of the superior safety, efficacy and cost-effectiveness as compared with surgical repair, which is associated with significant morbidity, mortality and costs. The treatment of choice has to be endoscopic, which is much easier and safer than the transhepatic approach, especially in the non-dilated duct, while another advantage over radiology includes the possibility for rapid definitive treatment of distal obstruction (e.g. residual stones). A leak from an extrahepatic duct heals rapidly, while a leak from an intrahepatic duct takes longer to heal and sometimes needs associated percutaneous drainage. Finally, the authors propose treating an extrahepatic bile leak merely with naso-biliary drainage without cutting the papilla, and an intrahepatic bile leak with endoscopic sphincterotomy, nasobiliary drainage and a bilio-duodenal endoprosthesis.
