经体表高频超声在肛周脓肿和肛瘘诊断中的应用

目的:回顾分析经体表高频超声诊断肛周脓肿和肛瘘的价值.方法:应用6～14MHz高频探头,对89例肛周脓肿和(或)肛瘘患者在肛门周围进行超声检查并与手术结果对比分析.结果:本组中,经体表高频超声对肛周脓肿诊断的灵敏度94.3%,特异度100%,阳性预测值100%,对肛瘘诊断的灵敏度85.4%,特异度95.1%,阳性预测值95.3%.结论:经体表高频超声能方便、直接、无痛苦、较为准确地诊断肛周脓肿和肛瘘.

Use of Surface High-frequency Ultrasound in Diagnosis of Perianal Abscess and Anal Fistula

Purpose: To discuss the value of surface high-frequency ultrasound in diagnosis of perianal abscess and anal fistula. Methods: Eighty-nine cases of perianal abscess and anal fistula patients were enrolled in the study. High-frequency probe (6 ～ 14 MHz) was used for the ultrasonography exam of them. Comparative analysis was done between the features of the ultrasonography and the surgical results. Results: The sensitivity, specificity and positive predictive value of the diagnosis of perianal abscess and anal fistula by high-frequency ultrasound were 94.3% , 100% , 100% , and 85.4% , 95.1% , 95.3 % , respectively. Conclusion: High-frequency ultrasound can diagnosis of perianal abscess and anal fistula more accurately.
