Use of a Balloon Rectal Catheter in Magnetic Resonance Imaging of Complex Anal Fistula to Improve Detection of Internal Openings

Abstract

Magnetic resonance imaging with BRCC may facilitate detection of internal openings in complex anal fistula.

The treatment of anal fistula: secondACPGBIPosition Statement – 2018

“…Rectal gadolinium‐DTPA (diethylenetriamine penta‐acetic acid) has been used to help to identify tracks, with limited benefit , and saline has been infused into tracks . The insertion of a rectal balloon during scanning may improve the detection of internal openings, although none of these techniques has been widely adopted. Intravenous gadolinium‐DTPA is widely used to provide dynamic contrast enhanced MRI (DCEMRI) with equivalent benefit to images obtained by short tau inversion recovery (STIR) sequences .…”
