Endoscopic diagnosis and treatment of biliary leak in patients following liver transplantation: a prospective clinical study.

Abstract

Endoscopic nasobiliary catheter or plastic stent placement is a safe and effective treatment for bile duct stricture occurring after bile leak resolution in most liver transplantation patients. Nasobiliary catheter combined with plastic stent placement may be the best choice for treating bile leak, because, theoretically, it may prevent the serious condition resulting from accidental nasobiliary catheter dislocation, and it may have prophylactic effects on upcoming bile duct stricture, although this should be further confirmed.
