Role of magnetic resonance imaging in diagnosis of perianal fistula: bridging the radiological and surgical divide.

Abstract

Objective: To determine the accuracy of magnetic resonance imaging in diagnosis and classification of perianal fistulae taking surgical findings as gold standard. Study Design: Prospective Cross Sectional study. Setting: Department of Radiology, Liaquat University of Medical and Health Sciences, Jamshoro. Period: 01-12-2021 to 31-08-2023. Methods: The non-probability consecutive sampling technique was used in this study. After taking the informed consent the MR imaging was be done to diagnose and classify the perianal fistula which was correlated with surgical findings. All the data will be entered and analyzed on SPSS version 21. Results: In this study the mean age of the patients was 42.25±13.44 years, the male to female ratio of the patients was 1.5:1. The sensitivity, specificity and diagnostic accuracy of MRI was 92.94%, 91.76% and 92.35% respectively taking surgical findings as gold standard. Conclusion: MRI has high diagnostic accuracy in evaluation of perianal fistulae and it helps in bridging the radio surgical divide.
