As this disease process and surgery only occur on an emergency basis, the surgeon on-call (pre-determined by each hospital's call schedule) will assess the patient and he/she will invite the patient to enrol in the study. The decision to undergo loop ileostomy or TAC will be left up to the discretion of the surgeon and the patient. In either case, the patient will be will be given the option to enrol in the study either in the investigational arm (loop ileostomy) or the control arm (TAC). We will concurrently perform a retrospective chart review at all participating sites from 01/2010 to 01/2014 to serve as a historical comparative control group (180 patients estimated). These patients will be identified from hospital databases by discharge and procedure codes. Chart review will be conducted using the same inclusion and exclusion criterias used for the prospective patients. The stable nature and incidence of C.difficile infection in Canada since 2009 and the well-established standard surgical approach (TAC) for FCDC (6) justify the comparison to a historical control.
