摘要
目的探讨高频彩色多普勒超声诊断肛周脓肿与肛瘘的临床应用价值。方法使用高频彩色多普勒超声对90例肛周脓肿或肛瘘患者进行检查,并将检查结果与手术结果对照。结果肛周脓肿与肛瘘的声像图与周围正常组织有明显的区别,对肛周脓肿的诊断特异度、阳性预测均是100%,灵敏度为94.3%;对肛瘘的诊断特异度与阳性预测值分别为95.1%、95.5%,灵敏度为85.7%。结论高频彩色多普勒超声检查对肛周脓肿的位置、大小、数目、范围及肛瘘瘘管的走行、数目具有很高的诊断价值,且方便、直接、无痛苦、诊断准确、易被患者接受。
Objective To study the clinical value of high-frequency color Doppler ultrasound in diagnosing perianal abscess and anal fistula. Methods Ninety cases of perianal abscess or anal fistula were inspected by high-frequency color Doppler ultrasound.The inspection results were compared with surgical findings. Results There were significantly differences in the sonogram between the tissue with perianal abscess or anal fistula and surrounding normal tissues.The diagnostic specificity of perianal abscess and the positive predictive value were 100%,the sensitivity was 94.3%;the diagnostic specificity of anal fistula the positive predictive value were 95.1% and 95.5%,the sensitivity was 85.7%. Conclusion High-frequency color Doppler ultrasound can ascertain the location,size,number and extent of perianal abscess and clearly estimate the trend and number of anal fistula,and it is simple,direct,painless,with high diagnostic accuracy,easily be accepted by patients.
