Okay so i got rid of my j-pouch last july and since then i have had problems with my barbie butt (no rectum/opening) not healing and because it wont heal i keep getting abscesses. My doctor wants to put a wound vac over it. Has anyone ever had a wound vac put on their bottom before? Did it work? Was getting a good seal hard? How long did you have to have it? Were you allowed to work with it? Anything you can tell me about it would be helpful.
