Objective To investigate the effect of the application of magnetic resonance cholangiopancreatography (MRCP) before laparoscopic cholecystectomy(LC) in patients with acute cholecystitis complicated with cholelithiasis.Methods 120 patients diagnosed with acute cholecystitis complicated with cholelithiasis were involved in this research.They all underwent examination with B ultrasound and MRCPbefore LCto find anatomic variations of the bile ducts and common duct stones.Results The images of 2 patients displayed anatomic variations of the cystic duct.1 patient presented common duct stones,and gained laparotomy common bile duct exploration,cholecystectomy and T tube drainage.The rest 23 patients underwent LC.Conclusion The condition and anatomicvariations of the bile ducts can be displayed by routine preoperative examination with MRCP,which helps to reduce opportunities for biliary tract injuries and retaine common duct stones to occur.%目的 探讨腹腔镜胆囊切除术(LC)治疗胆囊结石伴急性胆囊炎术前应用磁共振胰胆管成像(MRCP)进行评估的临床价值.方法 回顾性分析胆囊结石伴急性胆囊炎拟行LC 64例患者的病例资料.所有患者均行B超检查后收治入院,术前行MRCP检查分析肝外胆管变异和排除胆总管结石.结果 2例患者发现胆囊管解剖变异,3例胆总管下端结石患者行开腹胆总管切开取石胆囊切除+"T"管引流术,余61例均行LC.结论 胆囊结石伴急性胆囊炎患者LC术前行MRCP检查,有助于观察肝外胆管变异和胆总管结石情况,减少术中胆管损伤和胆总管结石残余的发生.
