目的探讨术中胆管造影在胆道手术中的应用价值。方法对 1 74例术中胆管造影病例进行分析 ,以 2 5 %泛影葡胺 30～ 40 ml对5 7例具有相对胆总管探查指征者经胆囊管残端注入 ,1 35例胆总管探查术后经 T管注入进行 X线造影摄片。结果前者阳性率 31 .5 8% ,后者结石残留率 1 8.75 % ,假阳性率 1 .79%。结论术中胆管造影简便易行 ,准确率较高 ,危险性小 ,如能准确掌握其适应症 ,对减少残石率 ,避免不必要的胆管探查术等具有较高的应用价值
Objective To explore the value of intraoperative cholangiography in biliary tract surgery. Methods One hundred and seventy-four cases of intraoperative cholangiography were analyzed. Fifty-seven patients with signs of relative common bile duct exploration were infused via cystic duct stumps with 30-40 ml of 25% diatrizoate and 35 cases of common bile duct exploration T tube after surgery by X-ray angiography. Results The former positive rate of 31.58%, the latter residual rate of 1 8.75%, false positive rate of 1.79%. Conclusions Intraoperative cholangiography is simple and easy to operate, with high accuracy and low risk. If it can accurately identify its indications, it is of high value in reducing the residual stone rate and avoiding unnecessary bile duct exploration
