Neomycin and Metronidazole Hydrochloride With or Without Polyethylene Glycol in Reducing Infection in Patients Undergoing Elective Colorectal Surgery

PRIMARY OBJECTIVES: I. To estimate the difference in rates of surgical site infection following elective colorectal resections in patients given a preoperative mechanical bowel prep with oral antibiotics as compared to preoperative oral antibiotics alone. SECONDARY OBJECTIVES: I. To determine rates of post-operative clostridium difficile infection, adynamic ileus, cardiopulmonary complications, urinary tract infection, length of stay and mortality in patients given preoperative oral antibiotics with a mechanical bowel prep versus preoperative antibiotics alone.
