Abstract

Objectives. Determine the relevance between magnetic resonance images and surgery in evaluating the inner hole and the horseshoe – shaped anal fistula. Subjects and Methods. Patients who are diagnosed with horseshoe – shaped anal fistula by taking magnetic resonance and sugery at Viet Duc Hospital from 2016 to 2019. This was a description study with control operation. Results. Among 56 patients including 50 males and 06 females, 62.5 percent of them are detected inner hole by taking anal magnetic resonance with the sensitivity of 100% and the specificity of 100%. The matching rate with surgery on classigyingfistula way is 93.3%. There is a high precision in taking anal magnetic resonance image to locate the inner hole, with the matching rate of 100%. Conclusions. Taking anal magnetic resonance has become the gold standard in anal fistula diagnosis, especially in horseshoe – shaped anal fistula before the surgery (classifying the main fistula tracts, locating the inner hole and defining the widespread injuries).
