The aim of this study was to analyze the patency of expandable metallic stents in @entity5 and to evaluate the efficacy of adjuvant therapy accompanied by biliary stenting. We analyzed 29 @entity1 in whom bile duct stenting was performed for @entity5 . Their types of disease were: hilar @entity513 (n = 8), @entity1086 (n = 11), and @entity3123 (n = 10). Initially, 46 expandable metallic stents were placed in 29 @entity1 . In 23 of the 29 @entity1 , adjuvant therapy was administered. Seventeen @entity1 underwent radiotherapy, and 16 @entity1 received various systemic chemotherapies. In principle, @entity221 was performed twice a week, simultaneously with radiotherapy. @entity1 survival and the probability of stent patency were calculated using actuarial life table analysis. There was no significant difference in stent patency among the @entity1 according to @entity66 . @entity221 did not influence the stent patency rate. The median stent patency time was significantly greater in the chemo-radiation group than in the no-adjuvant therapy group: 182 days versus 68 days, respectively (P = 0.017). Moreover, a significant increase was seen in the median survival time in the chemo-radiation group: 261 days versus 109 days (P = 0.0337). Complications occurred in 9 @entity1 (31.0%). @entity432 occurred in 6 @entity1 (20.7%), with all of these @entity1 managed successfully using a transhepatically placed new expandable metallic stent, employing the stent-in-stent method. Stent migration occurred in 2 @entity1 after radiotherapy. Adjuvant therapies such as radiotherapy and systemic chemotherapy, in combination with stent insertion, resulted in an increase in the patency period of expandable metallic stents and in increased @entity1 survival time.
