摘　　要：目的探讨胆肠Roux-Y吻合术后空肠桥袢结石的CT与MRI表现。方法回顾性分析5例经手术证实的胆肠Roux-Y吻合术后空肠桥袢结石的影像资料及临床表现,影像检查包括CT检查5例,MRI检查2例。结果5例皆有反复发作的右上腹痛,伴寒颤、高热3例,伴皮肤、巩膜轻度黄染1例。5例CT像上均见右上腹肠腔内圆形"树轮"状高密度结石影,结石及以上区域肠管扩张,无气-液平面。2例胆管积气。1例肝内胆管内有结石。MRI检查的2例示胆总管局部扭曲,吻合口下方肠管内示混杂信号结石,1例肝内胆管结石与积气并存。结论胆肠Roux-Y吻合术后桥袢结石CT与MRI均能明确诊断,MRCP对结石的定位判断更直观。Objective To investigate CT and MRI manifestation of jejunum loop stone after cholangiojejunos tomy. Methods The imaging data and clinical information of 5 patients with jejunum loop stone after cholangiojejunostomy con- firmed by surgery were analyzed retrospectively. 5 patients underwent CT examination, 2 patients underwent MRI examina- tion. Results All the 5 patients had recurrent episodes of abdominal pain, 3 patients accompanied with chill and hyper- pyrexia, 1 patients accompanied with mild cutaneous and scleral jaundice. Round ＂ concentric circle＂ high density stones were seen on CT in the right upper quadrant intestine of all 5 patients, without intestinal dilatation and air fluid level above the stone level of intestinal canal. 2 patients underwent MRI examination could be seen local choledochus distortion and mixed signal intensity stone below the stomas level of intestinal canal, 1 patient accompanied with intrahepatie bile duct stone and gas. Conclusion Jejunum loop stone after cholangiojejunostomy could be definitely diagnosed on CT and MRI, MRCP was more direct viewing for the location of stones.
