This is a fairly frequent question. Doubtful that colon transplant will occur, although there are some intestinal transplants that include the colon. That said, the reason it is unlikely is that to be a candidate for intestinal transplant, it has to be life preserving. This means that you cannot tolerate TPN anymore, and your intestines are so dysfunctional that you will die otherwise. The fact is that we can live pretty well without a colon, so it is not likely to be a priority. I suppose that if they figure out how to grow a colon from scratch that would actually work, that might be a possibility.
