Hello I am new to this forum. I really just have a question. The question is has anybody had experience using Humira to treat bowel to bladder fistulas? I was diagnosed with this fistula about two and a half months ago. I also have 35 centimeters active Crohn's disease. The surgeon wants to do surgery but my question is is this something that can be treated relatively successfully with you Humira? I have been on Remicade for 3 years and built up antibodies to the drug so this is why they want to switch if I choose to do it.I don't know how much information I need to put on here but I'm 43 years old and have had Crohn's since I was 13 having a major surgery at 17 removing approximately 3 feet of intestine. Have been on and off prednisone since and like I said started Remicade 3 years ago.any thoughts would be great i just want to see what people's thoughts are of Humira and its success rate. Cheers and blessings
