DIAGNOSTIC ROLE OF MRI IN THE PRE-OPERATIVE EVALUATION OF PERIANAL FISTULA

Abstract

Background- Ano-rectal fistulas are chronic inflammations of perianal tissues with a connection between the skin of the perineum and the anal canal.

Methods- This prospective  study was conducted in 35 patients during the period of one year and patients fulfilling inclusion and exclusion criteria was included in the study and was include data collection, data organization, presentation, data analysis and data interpretation. 

Results- Out of 35 patients examined with MRI, classification of fistula was done according to St. James’s University Hospital Classification of  perianal fistula. 13 patients (37.14%) had Grade 1 fistula, 8 patients (11.14%) had Grade 2 fistula, 4 patients (11.4%) had Grade 3 fistula, 6 patients (17.14%) had Grade 4 fistula and 4 patients (11.4%) had Grade 5.

Conclusion-Magnetic Resonance Imaging (MRI) was highly accurate in assessment of surgically important parameters of perianal fistulae.
