MRI EVALUATION OF PERIANAL FISTULAS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 86
Abstract
BACKGROUND Magnetic resonance imaging accurately demonstrates the anatomy of the perianal region fistulas, their relationship with ischiorectal fossa, classifying fistulas into five types. Magnetic resonance imaging depicts infectious foci in the perianal region and helps to reduce postoperative recurrence. The aim of the study is to evaluate the role of magnetic resonance imaging (MRI) in viewing and classifying perianal fistulas. MATERIALS AND METHODS This study is a descriptive study with 30 patients referred from Surgery Department. MRI was performed and was correlated with operative findings. A GE 1.5 Tesla MRI scanner was used. RESULTS 18 cases had intersphincteric fistula, 8 cases had trans-sphincteric type, 2 cases had suprasphincteric and 2 cases had extrasphincteric types. Abscess collections have been found in 15% patients. CONCLUSION MRI is a reliable diagnostic modality in the classification of perianal fistulas and can be an excellent diagnostic guide for successful surgical interventions with the aim to reduce the number of recurrences. Its advantage is that fistulas and abscesses are visible without the need to apply any contrast medium
