胆道支架位置对治疗低位恶性梗阻性黄疸的影响

目的 比较胆道支架跨与不跨十二指肠壶腹部放置治疗低位恶性梗阻性黄疸患者的临床预后差异.方法 分析本院符合条件的56例恶性梗阻性黄疸患者的临床资料,其中支架跨十二指肠壶腹部放置31例,支架不跨十二指肠壶腹部放置25例,比较2组患者间支架置入术后4~7 d总胆红素下降率、胆道感染率及支架再阻塞率等方面的差异.结果 跨壶腹部组与不跨壶腹部组的生存期分别为(180.3±142.5) d、(178.6±137.7) d(P=0.840).2组患者术后4~7 d总胆红素下降率为42.0%±43.6%、41.4%±28.7%(P=0.950);治疗成功率分别为93.5%、92.0%(P=1.0).跨壶腹部组术后胆道感染7例(22.6%),不跨壶腹部组术后胆道感染5例(20.0%)(P=0.815).2组患者支架再阻塞率分别为22.6%、28.0%(P=0.642).结论 2种支架置入方式均是治疗低位胆道梗阻安全、有效的方法;与支架非跨壶腹部放置相比,支架跨壶腹部放置未增加胆道感染及支架再狭窄发生率.

The impact of the location of biliary stent on treatment of lower malignant biliary obstruction

Objective To compare the difference in clinical prognosis of patients with low malignant obstructive jaundice treated by percutaneous biliary stent insertion across or above the duodenal papilla.Methods 56 patients with malignant biliary obstruction were reviewed retrospectively.Stents were placed above the duodenal papilla in 31 cases (group A) and across the duodenal papilla in 25 cases (group B).Total bilirubin reduction rate after 4-7 days of the procedure, biliary infection rate and stent occlusion rate were evaluated and compared between two groups.Results Mean survival periods were 180.3±142.5 days for group A and 178.6±137.7 days for group B (P=0.840).Total bilirubin level was decreased by 42.0±43.6% for group A and by 41.4±28.7% for group B after 4-7 days of the procedure(P=0.950);clinical success rates were 93.5% for group A and 92.0% for group B (P=1.0).Post-procedure cholangitis occurred in 7 cases (22.6%) in group A and 5 cases (20.0%) in group B (P=0.815).Stent occlusion rates were 22.6% and 28.0% for group A and group B (P=0.642).Conclusion For patients with lower malignant biliary obstruction, both of the two modalities of stent placement are safe and effective treatment.Stent placement across the duodenal papilla do not increase the development of stent occlusion or cholangitis compared with stent placement above the duodenal papilla.
