Patients will be randomized to receive a complete MBP or not prior to their surgical procedure. All patients will use 1 fleets enema the night before surgery and one the morning of surgery to ensure that the rectum is empty of all stool. This will be done since some surgeons use a rectal probe in the rectum to help with manipulation during the procedure. Stool in the rectal vault could contaminate the surgical field and lead to an infection.
