Preoperative antibiotics should be administered to all patients. Single- and multiple-drug regimens, as discussed in Medical Care, are appropriate choices. However, for patients with more extensive contamination, a single-drug regimen (with either imipenem/cilastin or piperacillin/tazobactam) or a multiple-drug regimen (with ampicillin, gentamicin, and metronidazole) may be warranted for peritonitis. Bowel preparation is usually possible for nonemergent situations.
