摘要
目的 :分析MRCP在Mirizzi综合征的诊断价值及影像特点。方法 :对经MRI和MRCP检查的 15例Mirizzi综合征患者 ( 8例手术证实 ,7例临床随访证实 )进行回顾性分析。结果 :15例中 2例为胆囊切除术后 ,13例伴慢性胆囊炎 ;Ⅰ型 7例 ,表现为胆囊管或胆囊颈部结石压迫肝总管 ,造成以上部位扩张 ,胆总管不扩张 ,Calot三角区结构清楚 ;Ⅱ型8例表现为胆囊管或胆囊颈部结石压迫肝总管 ,造成以上部位扩张 ,胆总管不扩张 ,Calot三角区结构不清楚。 15例肝内胆管形态均呈枯枝状。结论 :MRCP可提高Mirizzi综合征的术前诊断符合率 ,对选择合适的术式 ,避免医源性胆道损伤有很大意义。
Objective:To evaluate the diagnostic value and imaging character of MRCP for Mirizzi syndrome.Methods:15 cases of Mirizzi syndrome that underwent MRI and MRCP (8 cases confirmed by operation and 7 cases by follow up investigation) were retrospectively analysed.Results:In 15 patients, two cases were observed after tcholecystectomy and other 13 cases were accompanied by chronic cholecystitis. There were 7 cases of typeⅠ Mirizzi syndrome, in which the typical manifestation was the common hepatic duct compressed by calculus located in the cystic duct or the gallbladder neck, and the bile ducts above the obstruction were dilated but common bile duct was not, and the structure of the Calot triangular area was clear. In the 8 cases of Ⅱ type, besides the manifestation mentioned above,Calot triangular area was not well displayed.All 15 cases of both types demonstrate deadwoods like biliary tree.Conclusion:MRCP can improve preoperative diagnostic accuracy of Mirizzi syndrome. It is significant in operation selection and avoiding iatrogenic bile duct injury.
