Impact of Antibiotic Prophylaxis Change on Surgical Site Infections After Pancreaticoduodenectomy

Sponsor: Central Hospital, Nancy, France

Summary

Patients undergoing pancreaticoduodenectomy after preoperative biliary drainage are at increased risk of surgical site infections (SSI) due to bile colonization. Recent guidelines recommend the use of piperacillin/tazobactam instead of cephalosporins for antibiotic prophylaxis in this population. However, the relevance of this strategy may depend on local microbiological ecology. This monocentric ambispective cohort study aims to compare SSI rates between two periods: before and after implementation of piperacillin/tazobactam prophylaxis. The study also evaluates microbiological profiles of bile cultures, antibiotic susceptibility, and postoperative antibiotic exposure. The primary hypothesis is that adaptation of antibiotic prophylaxis to local ecology may optimize outcomes while limiting unnecessary exposure to broad-spectrum antibiotics.
