I have a fistula in my small intestines that is draining and filling an abscess in my lower abdomen, and a diseased part of my colon, they want to take out part of my colon, lower intestines and clean out the abscess.....I am worried because I've been feeling good since I've been on entyvio (6months) but the fistula doesn't seem to want to heal and continues to refill the abscess. From what I understand this won't stop until the fistula is healed or taken out. I would like the medicine to do its job and idk if surgery is the next step since it's only been 6 months I've been on it, I'm just overwhelmed with all that is going on.
