Subject identification will be carried out by the attending surgeon on call, eligibility will be evaluated, and patients will be approached for study participation. A consent for the study will be obtained from the subject or a legally authorized representative. 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). The patient will be given a consent form as soon as they are identified as a potential candidate by the surgeon-on-call. Once the patient and/or the legal representative have signed the consent form, the patient will be considered accrued to the study.
