I wasn't sure how to explain it well, so I went digging and found this awesome site on the Mayo Clinic about
RV fistulas and tests for them.
www.mayoclinic.com/health/rectovaginal-fistula/DS01065/DSECTION=tests-and-diagnosisI hope this helps and gives you some ideas! I haven't done any of these personally because mine was low enough that they could see it just doing a vaginal exam (at the bottom of the sphincter muscle). I have a draining seton in mine that I will probably leave there for a while. It almost healed completely last year when I started Remicade, but then I got c. diff. twice and pancreatitis several times, and all of that drama re-
opened it.
