Abstract:
Objective To evaluate the therapeutic effects of endoscopic biliary double stents for advanced malignant hilar biliary obstruction.Methods From January 2007 to December 2010,double stents was attempted in 28 patients (15 men and 13 women,median age 66.4 years (44-88 years),including 9 with Bismuth Ⅱ,8 with type Ⅲa,5 with type Ⅲb and 6 with type Ⅳ.A total of 23 consecutive patients ( 11 men and 12 women,median age 65.8 years (42-83 years) with malignant hilar obstruction undergoing a therapy with single stent were recruited as the control group,including 7 with Bismuth Ⅱ,5 with Ⅲa,6 with Ⅲlb and 5 with Ⅳ.The rates of successful drainage,complications,mean survival time of patients and the average duration of biliary stent patency were compared between the two groups.Results Successful rate of cannulation was both 100％ in the two groups.Successful rate of drainage and complications of double stent group were 96.4％ (27/28) and 17.9％ (5/28),and these two variables of single stent group were 87.0％ (20/23) and 13.0％ (3/23),which were not significantly different (P ＞0.05).23 patients (82.1％ ) in double stent and 19 ( 82.6％ ) in single stent group were followed up.The average duration of stent patency and mean survival time of double stent group were ( 129 ±48.5) d and ( 187 ±94.5) d,which were superior to those of the single stent group,i.e.( 102 ±37.8) d and ( 103 ±98.5) d.Conclusion Double stenting is an effective therapy for malignant hilar obstruction of Bismuth Ⅱ and above.It is superior to single stent method in the mean duration of patency and mean survival time.
