The broad-spectrum antibiotic piperacillin-tazobactam used as perioperative prophylaxis significantly reduced surgical site infection (SSI) in patients undergoing open pancreatoduodenectomy (PD, or the Whipple procedure) compared with the standard-of-care cefoxitin, according to results from the first-ever registry-linked surgical clinical trial conducted in North America. The findings, published in JAMA on April 20, support using piperacillin-tazobactam as a standard of care for this patient population.
