摘要
目的探讨肛瘘的超声表现及其临床诊断价值。方法回顾性分析腔内超声检查确诊为肛瘘的357例患者的超声图像表现,评价肛瘘与内外括约肌的关系、肛瘘的分型以及瘘管及内、外口的显示,并与手术结果进行对照。结果超声检查均能清晰显示瘘管。单纯性肛瘘患者超声诊断肛瘘位置、内口、外口、分型与手术结果的符合率均为100%(205/205),复杂性肛瘘患者的分别为95.4%(145/152)、85.5%(130/152)、100%(152/152)、84.9%(129/152)。超声诊断肛瘘位置、内口及分型与手术结果符合率均明显高于术前触诊检查结果[98.0%(350/357)vs68.1%(243/357),93.8%(335/357)vs60.5%(216/357),93.6%(334/357)vs57.4%(205/357),P<0.05]。结论对于肛瘘,经直肠超声是一种重要的术前诊断方法,具有较高的临床应用价值。
Objective To investigate sonographic characteristics and clinic value of perianal fistulas.Methods The clinical transrectal ultrasound and sonographic features of perianal fistula in357 patients were restrospectively analyzed.To evaluate the relationships among the fistula together with the internal or the external sphincter,the types of the fistula,the fistula positions,the internal and external openings were compared with surgical results.Results Fistula could be shown by ultrasound examination.Compared w...
