13例医源性肝外胆管狭窄的处理

目的:探讨医源性胆管损伤的预防及发生肝外胆管狭窄后的手术重建.方法:对13例医源性肝外胆管狭窄的诊断及处理结果进行分析.结果:13例医源性胆管损伤的病人,治愈11例,死亡2例.结论:①影像学检查是了解胆管狭窄病灶的重要手段.B超应为首选,但对于狭窄段的病变程度和范围则有欠缺,MKCP检查能补充B超不足之处,此两项检查能全面显示肝内外胆管树病变部位、程度和范围,以达到完善诊断.②胆管炎发作期间首先要控制感染,经非手术处理症状无改善者应果断采取急诊胆道外引流手术.③肝外胆管狭窄的手术技术要求胆肠合口直径>2.5cm,吻合口无张力,血运良好,空肠袢长度40～45cm,无扭曲悬吊.对于胆管扩张,缝合技术可靠,吻合口足够大者可不置放T管支架引流,但胆管扩张不明显,管壁增厚僵硬,炎症未得到控制或行左右肝管成形,左肝管扩大切开者应置放T管或Y形支架管,时间不少于6个月.

THE SURGICAL MANAGEMENT OF 13 CASES OF IATROGENIC EXTRAHEPATIC BILE DUCT STRICTURE

Objective:To study the prevention and operational treatment of iatrogenic extrahepatic bile duct stricture.Methods:A retrospective of 13 patients suffered iatrogenic extrahepatic bile duct stricture was conducted. In this study, the methods for diagnosis and treatment were reviewed and analyzed.Results:11 out of 13 cases were cured,whereas 2 patients died .Conclusions:Firstly,imaging examination plays an important role in diagnosis of extrahepatic bile duct stricture.Ultrasound should be the first choice,wh...
