hummmm..... i'm not sure, Christine.. isn't the anus a bit more than just an opening..? frankly, i don't know much about this - like you, i'm just now learning about this whole fistula situation.. you mentioned a hematoma, so i went and read some about this. from what i understood it's an internal bleeding of the tissues, so it makes sense and i guess it could be that's what it is and it's not a fistula at all, esp now that i'm finally assimilate that you in fact don't have a rectum..
for me, after 2 mons of lots of mucous and gas from my vagina and while i get my cycle - the blood goes from my vagina to my rectum (i still have my rectum), i asked a colorectal surgeon (my BIL's friend - a colorectal surgeon at UCLA), so he said it sounds like a fistula. but all of a sudden my symptoms have stopped almost completely, so he said it could be b/c i have an ileostomy, stools are not passing through the rectum, that's why my symptoms are minor.. (i'm in israel and i only consult with him through my BIL/sister by phone, so he can't really examine me).
so since you also have an ileostomy and esp since you don't even have a rectum, it makes more sense the cause for your symptoms is a hematoma and not a r/v fistula, i mean after all, if you don't have a rectum, then you can't have a recto-vaginal fistula....
gosh, there are so many deseased and conditions.... it's confusing, isn't it..? :/ but i'm sure your dr and you will figure it out eventuall!
