彩色多普勒超声检查早期诊断急性感染性胆囊炎的临床研究
Clinical study of color Doppler ultrasound for early diagnosis of acute cholecystitis infection
目的:探讨彩色多普勒超声检查早期诊断急性感染性胆囊炎的临床价值,以期提高急性感染性胆囊炎诊断水平。方法选择36例急性感染性胆囊炎患者为研究对象(观察组),随机选取同期体检正常者为对照组,观察两组彩色多普勒超声声像图的表现,测量两组肝动脉和胆囊动脉的血流最大峰值流速( Vmax)和阻力指数( RI)。采用ROC曲线观察彩色多普勒超声对该疾病的特异性。结果对照组胆汁透声差、胆囊壁厚、胆囊肿大、超声Murphy阳性发生率分别为25.0%、16.7%、22.2%、8.3%,观察组胆汁透声差、胆囊壁厚、胆囊肿大、超声Murphy阳性发生率分别为72.2%、47.2%、100.0%、94.4%,两组差异均有统计学意义(χ2=4.571、4.571、4.589、5.689,均P<0.05);两组肝动脉和胆囊动脉的Vmax和RI差异有统计学意义(P<0.05)。进行ROC曲线比较,观察组胆囊增大的正确率最高,为90.7%,特异性为90.7%,灵敏度为90.6%,与其他超声指标比较差异无统计学意义(χ2=0.893,P>0.05)。结论彩色多普勒超声检查能显示急性感染性胆囊炎的形态、胆囊壁程度、胆汁透声等情况,可提高对该疾病的诊断价值。
更多Objective To investigate the clinical value of color Doppler ultrasound in the early diagnosis of acute cholecystitis infection ,in order to improve the diagnosis of acute cholecystitis infection .Methods 36 cases with acute cholecystitis infection were selected as the observation group , and during the same period the healthy people were randomly selected as the control group .The color Doppler performance of ultrasound was observed .The hepatic artery blood flow velocity and the maximum peak of the cystic artery (Vmax) and resistance index(RI) were meas-ured.ROC curve was observed to evaluate the specificity of color Doppler ultrasound for the disease .Results The incidence rates of weak bile sound transmission ,gallbladder wall thickness ,gallbladder enlargement ,ultrasound Mur-phy positive in the control group were 25.0%,16.7%,22.2%,8.3%,which in the observation group were 72.2%, 47.2%,100.0%,94.4%,the differences were statistically significant (χ2 =4.571,4.571,4.589,5.689,all P<0.05).The differences in hepatic artery and the cystic artery Vmax and RI were statistically significant between the two groups(P<0.05).ROC curve comparison showed that the correct rate of gallbladder enlargement in the observa -tion group was the highest (90.7%),the specificity was 90.7%,sensitivity was 90.6%,and other indicators of ultra-sound had no significant difference (χ2 =0.893,P>0.05).Conclusion Color Doppler ultrasound can show the form of acute infectious cholecystitis ,gallbladder wall degree of bile through sound etc .,it can improve the diagnostic value of the disease.
