Manar T Alaat E Essawy

Objectives: This study was conducted to assess the diagnostic accuracy of magnetic resonance imaging (MRI) in perianal fistula in comparison to the operative findings with a description of the technique, illustration of relevant normal anatomy, and examples of various fistula types. This study is based on a retrospective analysis of 56 patients with a clinical diagnosis of perianal fistula. MRI finding was correlated with the surgical finding in 52 patients which is highly significant (P=0.003). Fallacies of MRI were observed in 4 patients with recurrent fistulae. Conclusions: MRI is useful in successful treatment of perianal fistulae by reliable assessment of fistula anatomy and correct assessment of the extent of the disease and its relation to the sphincter complex.
