目的通过术后经T管胆道造影,研究肝外胆管的解剖情况,以期对胆道手术提供一些帮助。方法对86例经T管胆道造影片的仔细测量,得到相关数据,如T管长臂下缘至胆总管下端的长度,胆总管汇人十二指肠的部位。结果86例造影片中T管长臂下缘至胆总管下端的长度为3．9～11．1 cm;72例胆总管汇入十二指肠降部的中下部,2例汇入十二指肠横部;有21例胆胰管同时显影。结论T管长臂下缘至胆总管下端的长度基本能反映出十二指肠球部上缘至胆总管下端的长度。对胆道外科手术提供一些帮助,减少术中探查引起的并发症。
Objective To study the anatomy of extrahepatic bile duct through postoperative T-tube cholangiography in order to provide some help for biliary tract surgery. Methods Totally 86 cases of T-tube cholangiography were carefully measured to obtain the relevant data, such as the length from the lower edge of the T-tube to the lower end of the common bile duct, and the site of human common duodenum. Results The length of the lower edge of the long arm of T tube to the lower end of the common bile duct in 86 patients was 3.9 ~ 11.1 cm. 72 common bile duct vessels merged into the middle and lower part of the descending part of the duodenum, The transverse section of the bowel; 21 cases of pancreatic duct at the same time development. Conclusion The length of the lower edge of the T-arm to the lower end of the common bile duct basically reflects the length of the upper edge of the duodenal bulb to the lower end of the common bile duct. Biliary surgery to provide some help to reduce the complications caused by intraoperative exploration.
