[Evaluation of biliary stenting therapy for malignant biliary stricture at our hospital]

The clinical results of biliary stenting therapy for non-resectable malignant biliary stricture were assessed for patency periods and survival periods in consideration of the types of stents and disease. The subjects were 51 patients with non-resectable malignant biliary stricture due to disease of the pancreas and biliary tract treated at our hospital between April 2001 and March 2005. No significant differences were observed in the patency periods and survival periods among the various types of stents. In regard to the type of disease, the survival period for biliary tract cancer was longer (616 +/- 246 days) than those for other diseases. There was no difference in the number of times of stenting among the various stents, and jaundice was effectively reduced. No patients in our series died of failure to reduce jaundice. We therefore considered it necessary to choose a proper stent indwelling route and a stent type according to stricture site, disease type and PS (performance status) at the time of stenting. The usefulness of the biliary stenting therapy for non-resectable malignant biliary stricture was suggested.
