G.I. specialist said I need surgery due to Crohn s disease. I have been treated for colitis / crohn s with Entyvio, 4 treatments, and Stelara, 2 treatments, did not result in remission. MY QUESTION: 6 years ago a surgeon implanted large mesh, about 7x10 due to 2 cm hernia. DOES THE MESH become obstruction for surgery to remove entire colon, stoma, affix bag?
