fistulas - Lisa

I'm clearly hearing history of "intracutaneous fistulas" dictated, however, when I search for that in both the dictionary and Google, etc., I only find enterocutaneous fistulas, which would make sense as this patient has bowel problems. But someone else is telling me that it's a fistula "within the skin", but I can't find that there is such a thing. Should I just go with entero and quit worrying about it? Thanks for your any input you can send me!
