Biliary drainage is a standard procedure for cholangitis or obstructive jaundice due to biliary obstruction. However, criterion for the selection of types of drainage tube is not established. The authors analyzed the types of drainage tube used in the University of Tokyo, Tokyo, Japan, during the month of June 2005, and they treated 63 cases. For drainage for cholangitis (31), the authors used endoscopic naso‐biliary drainage (ENBD) tube in 74.1% and plastic stent in 25.9%. In contrast, for the cholestesis cases (16), the authors used ENBD tube in 37.5% and plastic stent in 63.5%. For the unresectable biliary malignancy cases (8) with improved jaundice, the authors used covered metallic stent in seven distally stricture cases and uncovered metallic stent in one proximally stricture case. The remaining eight cases received plastic stent placement. There were six cases of residual common bile duct stones and two cases of prevention of cholangitis after papillectomy. For the patients with unresectable biliary malignancies at distal portion, the authors consider that covered metallic stent is a standard endoprosthesis. For drainage for cholangitis, the authors used ENBD tube because bile juice flow is able to be checked any time. However, the authors used plastic stent rather than ENBD tube for the drainage of cholestesis. A larger study for selection of drainage tube for these aspects is needed in the future.
