MRCP诊断胆囊管变异的临床价值

目的 利用磁共振胆胰管成像 (MRCP) 观察胆囊管的正常解剖及变异, 探讨胆囊管变异与胆囊结石的相关性.方法 回顾性分析符合纳入标准的371例MRCP检查患者, 比较胆囊管变异与正常胆囊管发生胆囊结石的差异.结果 371例患者出现胆囊管变异63例, 其中22例存在复合变异, 共85个变异点, 变异率为16.98%.胆囊管变异者发生胆囊结石53例, 胆囊管无变异者发生胆囊结石182例.结论 MRCP可清晰显示胆囊管各种变异, 且胆囊管变异患者发生胆囊结石几率较无变异者高.

The Value and Discussion of Cystic Duct Variation Diagnosed by MRCP

Objective To observe the normal anatomy and variation of cystic duct by MRCP, and to explore the correlation between anatomic variation and gallbladder stones. Me thods To have a retrospective analysis of 371 MRCP patients which meet the requirement of imaging, and to compare the differences between anatomic variation and gallbladder stones with normal cystic duct. Re s ults Among 371 patients, 63 had anatomic variations, A among which, 22 had compound variations with 85 variation points in total.The percentage of mutation rate was16.98%. 53 patients with variation of cystic duct had gallbladder stones, and 182 patients without variation of cystic duct had gallbladder stones. Conclus ions MRCP can clearly display different variations of cystic duct, and the patients with variation of cystic duct have higher risks in gallbladder stones than the patients without variations.
