Comparison between the Accuracy of Endoanal Ultrasonography and Body Coil MRI in Preoperative Assessment of Internal Opening of Perianal Fistula Complex
Abstract Background and Aim: Surgery for anal fistula is a commonly performed practice. Integral part of fistula surgery is identification of the internal opening if high recurrence rate is to be diminished. In this study, accuracy of endoanal ultrasound versus body coil M.R.I in detection of the internal fistula opening was evaluated by comparing both modalities with the intra operative findings as a standard reference
