No. The large intestine is not transplanted because it's not an organ critical to life and transplantation poses such a risk of immunorejection that it necessitates the use of lifelong anti-immunorejectio therapy. Those drugs in turn make a person signficantly susceptible to serious ilness from what would otherwise be minor infections.quote:the question is: is it possible to have a large intestine transplant,
The enteric nervous system is self-contained in the intestine wall, so it would definnitely come along.quote:I'm not sure how much of the Enteric Nervous System would come with the Colon, or if you could hook the new one up to the old one properly.
These nerves would have no connections to the transplanted section, so unless there was a phantom pain phenonmenon taking place (not that II know about), that would also be "fixed".However, the enteric nervous system is a functional continuum from end to end and that would get disrupted, so the few people who have had can have symptoms that may, in fact, be worse than IBS. For one thing, the brain in the head is needed to expand and empty the stomach and also to initiate defecation. Those things would no longer work properly. Still, the problem of immunorejection and related problems, such as lymphoproliferative disease, are already enough to deal with!quote: (things that light up different when you trigger rectal hypersensitivity in IBSer in PET scan type of things).
