Abstract
A fistula is defined as an abnormal connection between two structures or organs or between an organ and the surface of the body. In case of perianal fistula, it is an abnormal connection between anal canal and perianal skin.
In the past, imaging techniques played a limited role, but now it is increasing, especially the use of MRI. In this study we tried to correlate MRI and intra-operative findings and discussed the usefulness of MRI in surgical management of perianal fistula.
MRI is able to adequately evaluate and classify perianal fistula disease with a high degree of accuracy.
Keywords: fistula-in-ano, MRI, intraoperative findings.
