OBJECTIVE
This study aims to investigate the diagnostic value of three-dimensional pelvic ultrasound in the preoperative assessment of anal fistula compared with findings of MRI and surgery.
METHODS
A total of 67 patients (62 males) with suspected anal fistula were analyzed retrospectively. Preoperative three-dimensional pelvic ultrasound and magnetic resonance imaging were performed in all patients. The number of internal openings and the type of fistula were recorded. The accuracy of three-dimensional pelvic ultrasound was determined by comparing these parameters with surgical outcomes.
RESULTS
At surgery, 5 (6%) were extrasphincteric, 10 (12%) were suprasphincteric, 11 (14%) were intersphincteric, and 55 (68%) were transsphincteric. There was no significant difference in the accuracy of pelvic 3D US and MRI, based on internal openings (97.92%, 94.79%), anal fistulas (97.01%, 94.03%), and those under Parks classification (97.53%, 93.83%).
CONCLUSION
Three-dimensional pelvic ultrasound is a reproducible and accurate method for determining the type of fistula and detecting internal openings and anal fistulas.
目的
本研究旨在探讨三维骨盆超声在肛瘘术前评估中的诊断价值，并与 MRI 和手术结果进行比较。
方法
回顾性分析了 67 例（62 例男性）疑似肛瘘的患者。所有患者均行术前三维骨盆超声和磁共振成像检查。记录内口数量和瘘管类型。通过与手术结果比较，确定三维骨盆超声的准确性。
结果
手术中，5 例（6%）为括约肌外瘘，10 例（12%）为括约肌上瘘，11 例（14%）为括约肌间瘘，55 例（68%）为经括约肌瘘。基于内口（97.92%、94.79%）、肛瘘（97.01%、94.03%）和 Parks 分类（97.53%、93.83%），三维骨盆超声和 MRI 的准确性无显著差异。
结论
三维骨盆超声是一种可重复、准确的方法，可用于确定瘘管类型和检测内口及肛瘘。
