摘要
目的探讨B超、磁共振胆胰管成像（MRCP）、内镜逆行胰胆管造影术（ERCP）在胆总管结石诊断中的价值。方法收集2005年8月至2007年10月怀疑为胆总管结石且同时行B超、MRCP、ERCP的患者384例，对3种检查方法进行比较分析。结果384例患者中，最后经ERCP确诊胆总管结石者370例；B超诊断胆总管结石者268例，其中8例为假阳性，诊断准确率为70．3％（260／370）；MRCP诊断362例，其中6例为假阳性，诊断准确率96．2％（356／370）。有7例患者MRCP发现有胆总管结石和胆总管扩张，ERCP造影仅发现胆总管扩张，但在用取石网篮和取石气囊清理胆道时取出小结石。结论B超对于胆总管结石的诊断具有一定的准确率，可作为最基本的检查手段，MRCP和ERCP对于胆总管结石的诊断具有较高的一致性，MRCP可部分替代诊断性ERCP，联合应用MRCP和ERCP可提高胆管结石诊断准确率。
Objective To compare the diagnostic value study the technique of uhrasonography, magnetic resonance cholangiopancreatography（MRCP） and endoscopic retrograde cholangiopancreatography （ERCP） in common duct stones. Methods Three hundreds and eighty-four patients suspected common duct stones from August 2005 to October 2（107 were undergone abdominal uhrasonography,MRCP and ERCP. Results There was stone in common duct in 370 and no stones in 14 of 384 patients. Ultrasonography indicated stones 268 cases,8 false positive result was among them. MRCP diagnosed stones in 362 cases and false positive result in 6 cases, ERCP diagnosed stones 370 cases. The diagnostic accuracy of uhrasonography, MRCP and ERCP was 70.3% （260/370）, 96. 2% （ 356/370 ） and 100% respectively. Conclusions The diagnostic accuracy of uhrasonography for common duct stone was little higher, US should be used as a primary checking method. There was higher concordance between MRCP and ERCP for common duct stone. Combination of MRCP and ERCP can improve diagnostic accuracy of common duct stone.
