Background: Endoanal ultrasound (EAUS) and magnetic resonance imaging (MRI) of the pelvis are commonly employed for imaging of perianal fistulae, sinuses, and abscesses. The present study was conducted to assess role of transcutaneous perianal ultrasonography in assessment of perianal fistulae with MRI correlation. Materials & Methods: 74 cases of perianal fistulae of both genders underwent perianal sonography and MRI examinations. Results: Out of 74 patients, males were 44 and females were 30. Type was intersphincteric in 38, transsphincteric in 36 and suprasphincteric in 1. The difference was significant (P< 0.05). St. James’s classification showed grade I in 30, grade II in 16, grade III in 10, grade IV in 14 and grade V in 4 cases. The difference was significant (P< 0.05). Detection of primary fistulous and sinus tract was positive on TPUS and MRI in 74 cases, detection of secondary tracts/ramifications was positive on 8 cases on TPUS and 9 cases on MRI, detection of abscess was seen in 11 cases on TPUS and 10 cases on MRI and detection of internal opening was seen in 70 cases in TPUS and 72 cases of MRI. Conclusion: TPUS is an effective imaging modality in the evaluation of perianal fistulae. It has high sensitivity and specificity in diagnosing and classifying perianal fistulae and abscess comparable with MRI.
