彩色超声诊断胆总管结石的价值

Evaluation of color Doppler ultrasound diagnosis of choledocholithiasis

目的探讨彩色超声诊断胆总管结石的价值。方法胆总管结石患者100例术中分别采用彩色超声检查和胆管造影术进行诊断，比较两种检查方法的敏感性、特异性、准确性及检查耗时。结果经手术确诊为胆总管结石90例，占90％。术中彩色超声检查正确诊断者88例，假阴性2例，无假阳性；术中胆管造影术正确诊断者87例，假阴性3例，假阳性2例；两种诊断方法的敏感性、特异性及准确性比较差异均无统计学意义（X^2=0．23、1．25、0．57，均P〉0．05）。术中彩色超声检查时间为12-28min，平均检查耗时（16．57±4．12）min；术中胆管造影术检查时间为12—37min，平均检查耗时（21．09±6．24）min；差异有统计学意义（t=6．53，P〈0．05）。随访5～12个月，无残余结石患者。结论术中彩色超声具有无创、方法简便、安全、省时、可重复性好、成功率高等优点，可为胆总管结石的主要检查手段。

Objective To explore of the color Doppler ultrasound diagnosed choledocholithiasis. Methods 100 cases with choledocholithiasis diagnosed by color ultrasonography and cholangiography were analysed retrospec- tively. The sensitivity, specificity, accuracy and the inspection time of two methods were compared. Results 90 cases were diagnosed after operation,90% in 100 patients. The diagnostic accuracy of Doppler ultrasound was 88 cases,2 false negative cases, no false positive. The diagnostic accuracy of cholangiography was 87 cases, 3 false negative cases, 2 false positive cases. The sensitivity, specificity and accuracy of two groups were not statistically significant （ X2 = 0. 23,1.25,0.57, P 〉 0.05 ）. The inspection time of color ultrasound was 12 - 28min, the average inspection time was （ 16.57 ±4.12） min. The inspection time of cholangiography was 12 ~ 37rain,the average inspection time was （21.09 ± 6.24 ） min. The inspection times of two ways were statistically significant （ t = 6.53 ,P 〈 0. 05 ）. Followed up between 5 months and 2 years,there was no residual gallstone patients. Conclusion Color Doppler ultrasound is a noninva-sire, safe, time-saving, simple, good repeatability, high successful rate, for common bile duct stones in the main exami- nation methods.
