目的应用气囊导管,在纤维胆道镜直视下选择肝内胆管造影,探讨其对肝内胆管结石的诊断价值。方法对80例手术后确诊肝胆管结石患者进行回顾性研究,应用T管造影仍不能确定肝内胆管结石者,通过 T管窦道,应用纤维胆道镜对可疑胆管进行选择造影。结果经确认T管造影漏诊的17例,经气囊导管造影, 漏诊仅1例。结论气囊导管造影法的准确性明显高于T管造影法,对可疑肝内胆管结石者应尽量用气囊导管造影,必要时超选择性胆管造影。
Objective To evaluate the diagnostic value of intrahepatic cholangiography in choledochofiberscope by using balloon catheter. Methods A retrospective study was performed on 80 patients with hepatolithiasis confirmed after operation. T-tube angiography was still not able to confirm intrahepatic bile duct stones. Through choledoch sinus duct, cholecystolithiasis was used to select suspicious cholangiography. Results confirmed by T-tube angiography missed diagnosis of 17 cases, the balloon catheter imaging, missed only 1 case. Conclusions The accuracy of balloon catheterization is obviously higher than that of T tube angiography. For suspected intrahepatic bile duct stones, balloon catheterization should be used as much as possible, and ultraselective cholangiography should be performed if necessary.
