Diagnostic Utility of MRI in the Evaluation and Surgical Management of Primary Anorectal Fistulas: A Prospective Observational Study

Abstract

Background: Accurate diagnosis and classification of primary anorectal fistulas are essential 
for successful surgical treatment. Magnetic Resonance Imaging (MRI) is increasingly used as 
a preoperative tool to assess fistulous tracts, internal openings, and associated complications. 
Objective: To evaluate the effectiveness of MRI in diagnosing, grading, and assessing 
primary anorectal fistulas and to correlate MRI findings with intraoperative surgical 
outcomes.
