摘要
目的分析经直肠腔内超声在诊断肛瘘方面的临床价值。方法采用5~10 MHz直肠腔内小凸阵与线阵探头相结合的诊断方法,回顾性分析30例肛瘘手术患者的超声声像图,并与临床体检、手术结果相对照。结果腔内超声诊断肛瘘内口符合率低,为9.7%,管道与伴随积液符合率高,为93.8%和100.0%。结论腔内超声能清晰显示瘘管走向,检出体检不易发现的隐匿性积液,对降低手术复发率有很高的临床价值。
Objective To analyze the clinical value of transrectal ultrasound in the diagnosis of anal fistula.Methods A total of 30 inpatients was enrolled in this study.Transrectal ultrasound with 5-10 MHz convex and linear transducers was performed in all cases before operation.Ultrasound findings were analyzed and compared with clinical,surgical and pathological findings.Results The coincidence of detectiing internal opening of anal fistula with transrectal ultrasound was low(9.7%),however,the coincidence of detecting tracts of anal fistula was 93.8%,and the coincidence of detecting fluid collections was 100% with transrectal ultrasound.Conclusion Transrectal ultrasound can delineate the anal fistula track,identify the occult purulent fluid collection hard to locate by physical examination,which is highly valuable clinically.
