I can understand your frustration of nothing has worked so far. My son had an ileocecectomy last year because high dose remicade and mtx were unable to completely clear a chronic area of inflammation at the ileocecal valve. My son was asymptomatic from the active disease but unable to gain weight and the narrowing at the ic valve was concerning.
Our hope was that after surgery the remicade could control everything (it had been effective with symptoms and other areas in the TI excluding the area at the ic valve). Unfortunately, when he started remicade back after surgery he had developed antibodies. We moved to humira and three months in his colonoscopy showed visually pristine bowels. But, the biopsies showed inflammation at the cellular level present at the surgical site. He'll have another scope done in December and we're hoping for the best.
