肝胆管结石术后胆道镜检查与经T管胆道造影176例对比分析

目的评估术后经T管胆道造影和胆道镜检查在肝胆管结石术后的意义。方法对176例肝胆管结石行胆总管探查T管引流术后病人,在T管胆道造影基础上常规辅以胆道镜检查。结果176例病人中,造影检查明确或怀疑有残留结石者共39例,其中胆道镜证实者31例,另外8例胆道镜检查未见结石;造影检查未发现结石的137例病人中,胆道镜检查发现有残留结石者13例。结论经T管胆道造影存在一定的假阴性,联合术后胆道造影和胆道镜检查可进一步降低残余结石的发生率。

Comparative analysis between choledochoscopy and T-cholangiography postoperatively in 176 cases with choledocholithiasis

Objective To determine the value of choledochoscopy and T-cholangiography postoperatively in choledocholithiasis. Methods 176 patients with choledocholithiasis underwent common bile duct exploration-T tube drainge, all of them received T-cholangiography postoperatively; meanwhile choledochoscopy was performed. Results Of the 176 patients, residual duct stones were defined or dubious by T-cholangiography in 39 cases, 31 confirmed by choledochoscopy. In 137 cases without choledocholithiasis found by T-cholangiography, 13 cases were found having residual duct stones by choledochoscopy. Conclusion The pseudo-negative results maybe exist by T-cholangiography in patients with choledocholithiasis. Choledochoscopy combined with T-cholangiography can reduce the recurrence of residual duct stones.
