The University of Pittsburgh Medical Center does small bowel replacement (but you have to be very, very ill to qualify). Not sure what they do with ileo-cecal valves.
My ileo-cecal valve was removed 2001. Very healthy before removal. After removal I daily experience fatigue, flu-like symptoms - especially upon waking, 4-10 bms/day (mostly very loose and urgent) and live on a very limited diet of mostly white rice, avocado, sweet potatoes (Stokes are my favorite) and soup broth - - otherwise symptoms worsen. In 2001, I was 5' 10" and 150 lbs of muscle - today I am 123 lbs. I appear yellow in sunlight and have high bilirubin but the medical profession says its a red herring. Things that help: IBgard (OTC enteric coated peppermint oil); Visbiome (probiotic); herbal teas (elderberry, cats claw, nettles, echinacae, astragalus and several others); other items most naturopaths recommend; sticking to my limited diet; and keeping stress low (meditation helps). The road is challenging and there may not be anyone around you who understands - the ill ones have their own challenges and the healthy ones have a different focus. I wish you a quick and full recovery - - however - - if that does not happen - - I wish you strength and courage to bear your illness as best you can.
