目的 :评价术中胆道造影胆道探查的指征意义。方法 :术中采用由胆囊管或胆总管注射 2 0 %～ 3 0 %胆影葡胺造影。结果 :胆囊结石术中胆道造影 186例 ,结石阳性 70例占 3 7 63 % ,其中胆囊管开口变异 1例 ,假阳性 4例 ;116例结石阴性 ,假阴性 3例。结论 :胆道造影结果表明可以及时发现结石阳性病人和胆道变异病人 ,切开胆总管探查取石 ,避免术后结石的残留和术中胆道损伤 ;同时对阴性病人免遭胆总管的探查 ,避免术后并发症的发生
Objective: To evaluate the significance of intraoperative cholangiography and biliary tract exploration. Methods: Intraoperative use of cystic duct or common bile duct injection of 20% ~ 30% bile meglumine contrast. Results: There were 186 cases of cholecystolithiasis choledochography, 70 cases of stones were 373%, including 1 cases of cystic duct opening variation, 4 cases of false positive results, 116 cases of stone negative and 3 cases of false negative results. Conclusion: The results of cholangiography showed that patients with positive stones and biliary tract abnormalities could be found in time. The common bile duct exploration was performed to avoid the postoperative residual stones and intraoperative biliary tract injury. At the same time, the negative patients were excluded from the common bile duct exploration and postoperative Complications occur
