If belly pain or diarrhea continues one month after the transplant, the study doctor will want to repeat a stool test for C-diff. Sometimes the patient is not cured and a second transplant is needed. If a second transplant is needed, the same donor can be used if he/she is willing. The second transplant will be done by enema. The donor would have lab (blood and stool tests) done again to be sure she/he does not have any new infections or illness.
