Role Of Magnetic Resonance Imaging In The Preoperative Assessment And Grading Of Anorectal FistulasIn A Tertiary Care Hospital

Anorectal fistulas are complex conditions that significantly impact patients' quality of life. This study evaluates the role of Magnetic Resonance Imaging (MRI) in the preoperative assessment and grading of anorectal fistulas in a tertiary care hospital. Anorectal fistulas are characterized by a pathological connection between the anorectal lumen and an external perineal opening, primarily resulting from infections and gland obstructions. The research involved a descriptive, cross-sectional design, assessing 56 patients referred for MRI fistulograms. MRI was utilized to identify internal and external openings of fistulous tracts, their relationship to the anal sphincter complex, and the presence of complications such as abscesses. The results revealed a predominance of trans sphincteric fistulas (48.2%) and significant correlations between MRI findings and surgical outcomes, with 85.7% showing a strong correlation. MRI's non-invasive nature and ability to provide high-resolution, multi-planar images make it the gold standard for evaluating anorectal fistulas. Furthermore, the study highlights the effectiveness of MRI in enhancing diagnostic certainty and optimizing surgical planning, ultimately contributing to improved patient care and reduced healthcare costs. The findings advocate for the increased use of MRI in managing anorectal fistulas, underscoring its value in clinical practice.
