摘要目的：间置空肠胆管十二指肠吻合术，存在着胆肠逆流问题至今仍未能理想地解决，为了解决这一难题，设计了间置空肠远端悬垂法。研究方法：间置空肠远端悬垂法，就是将长2.5 cm左右间置的空肠远端悬垂于十二指肠内2.5 cm。术中测试胆道内压及测定胆汁生化成分并与术后所测的结果作对比；术后作钡餐检查及T管胆道造影，另还进行术后随访观察。结果：临床应用15例胆石症患者，经术后胆道内压力测定均较术前明显下降。术后钡餐检查，令患者取多种体位未见有胆肠逆流的征象出现。胆管造影见间置肠管蠕动良好，不断地将造影剂自胆道推向十二指肠。术后随访14例无反流性胆管炎及结石复发的临床表现。结论：间置空肠远端悬垂胆管十二指肠吻合术，具有强大的防胆肠反流的功能，同时又避免了现存的一些防胆肠反流术式的缺点，在临床上具有广泛的应用前景。

abstractsObjective:Cholangioduodenal reflux is still an unresolved problem in interposed jejunal choledochoduodenostomy (IJC) yet.To settle this problem,we designed IJC with distal suspending (IJCDS).Methods:IJCDS is to insert and suspend the distal end of the 25 cm-ling interposed jejunum to the duodenal cavity,which is about 2.5 cm long.The pressure of the biliary tract and the biochemical composition or the bile were measured during and after the operation and the results were compared.Barium meal and cholangiography through T tube were performed after the operation.Follow-up surveys were also done.Results:The pressure or the biliary tract decreased distinctively after the operation.Barium meals found no cholangioduodenal reflux although the patients had changed many postures.Cholangiography through T tube showed parisaltic or the interposed jejunum and the contrast medium was continuously pushed into the duodenum.Noreflux cholangitis and stone recurrence were found in the follow-up survey in 14 patients.Conclusion:IJCDS has the powerful function on preventing cholangioduodenal reflux.On the other hand,it avods the shortcomings of other reflux-preventing operative pattern.So it had the good prospect to extend its clinical usage.
