Objective To discuss the value of biliary stent in treatment of malignant biliary obstruction with different pathways of bile duct stent insertion. Methods Fourty-two cases of malignant biliary obstruction whose biliary stent insertions were through operation (n=18), PTCD (n=17) and ERCP (n=7) respectively were reviewed retrospectively. Results The bile duct stents were successfully inserted in all patients through the malignant obstruction and achieved internal biliary drainage. Compared with the level of the bilirubin before operation, it decreased about 100 μmol/L one week after the stent insertion in all patients. Compared with the levels of glutamic oxalacetic transaminase, glutamic pyruvic transaminase, alkaline phosphatase and glutamyltranspeptidase before operation, they decreased 1 week after the stent insertion （Plt;0.05). The median survival time was 22 weeks. The average survival time was (32.89±33.87) weeks. Two patients died in hospital after PTCD, and the mortality was 4.76%. Complications included 8 cases of cholangitis, 3 cases of bile duct hemorrhage and 2 cases of hepatic failure. Conclusion The bile duct stent insertions through operation, PTCD and ERCP are all effective in relieving the bile duct construction with malignant biliary obstruction. Each method should be chosed according to the systemic and local condition for every patient so as to improve the safety and efficiency, and to decrease the occurrence of complications.
目的 研究直肠癌切除后肠吻合前进行肠腔灌洗的临床作用。方法 对我院2006年6月至2007年2月期间连续56例行直肠癌低位前切除吻合的病例在切除原发灶、行远端封闭吻合前行生理盐水远端肠腔灌洗，收集灌洗前、后2份标本分别涂片行细胞学检查。结果 灌洗前收集液中观察到肿瘤细胞或核异形细胞者7例，中性粒细胞者24例，上皮细胞者4例； 灌洗后所有患者的收集液中均未观察到肿瘤细胞（P＜0.05），19例仍有少许中性粒细胞或上皮细胞。结论 低位直肠癌远端肠腔有可能存在脱落的肿瘤细胞。对直肠癌患者手术切除病灶后吻合前行远端肠腔灌洗的方法简单易行，可以显著减少或清除肠腔内可能残留的肿瘤细胞，从而可避免此类原因所致的局部肿瘤复发，值得提倡。
