急性阑尾炎早期动态演变中的超声监测

Dynamic evolution of acute appendicitis monitored by ultrasonography

目的探讨彩色多普勒超声对不同时期急性阑尾炎诊断中的价值。方法 246例诊断急性阑尾炎患者急诊行彩色多普勒超声检查,明确阑尾炎的表现形式,按不同的发病时间分类,并与手术结果进行对照研究。结果 246例急性阑尾炎患者中,经超声准确诊断者232例,诊断符合率94.31%,其中发病时间12h内的阑尾炎患者24例,超声准确诊断20例,诊断符合率83.33%,12～24h内的阑尾炎患者64例,超声准确诊断59例,诊断符合率92.19%;24～72h内的阑尾炎患者122例,超声准确诊断118例,诊断符合率96.72%;超过72h的阑尾炎患者36例,超声准确诊断35例,诊断符合率97.22%。结论彩色多普勒超声在不同时期急性阑尾炎中的特征性表现,有利于明确诊断阑尾炎严重程度,指导临床治疗。

Objective To explore the clinic application value of color Doppler ultrasound in the diagnosis of acute appendicitis at different stages. Methods Two hundred and forty-six patients with acute appendicitis were examined by color Doppler ultrasound and classified according to the different stages. Results 232 patients were diagnosed by color Doppler ultrasound,and the accurate rate was 94.31%.Within 12 h, 20 patients were diagnosed by color Doppler ultrasound,and the accurate rate was 83.33%.During 12 h and 24 h, 59 patients were diagnosed by color Doppler ultrasound, and the accurate rate was 92.19%. During 24 h and 72 h, 118 patients were diagnosed by color Doppler ultrasound, and the accurate rate was 96.72%. Beyond 72 h, 35 patients were diagnosed by color Doppler ultrasound,and the accurate rate was 97.22%. Conclusion The appearance of color Doppler ultrasound in different phases of the acute appendicitis is good to diagnose the acute appendicitis and direct the clinic treatment.
