In this context, perioperative antibiotic prophylaxis is essential, and recent guidelines recommend the use of piperacillin\u002Ftazobactam in selected high-risk patients.\n\nHowever, piperacillin, like other β-lactam antibiotics, exhibits pharmacokinetic variability that may be exacerbated during major surgery due to factors such as fluid shifts, hypoalbuminemia, and changes in volume of distribution. These alterations may result in suboptimal antibiotic exposure during the perioperative period, potentially compromising prophylactic efficacy.\n\nDespite these concerns, standard dosing regimens remain unchanged across different types of major abdominal surgery, including hepatic and pancreatic procedures, which differ significantly in terms of duration, physiological impact, and intraoperative management.\n\nThe PROPHTAZ study is a prospective, single-center observational pharmacokinetic study designed to evaluate whether standard perioperative administration of piperacillin\u002Ftazobactam achieves predefined pharmacokinetic\u002Fpharmacodynamic (PK\u002FPD) targets in patients undergoing hepatic or pancreatic surgery. The primary objective is to determine the proportion of patients achieving adequate PK\u002FPD exposure during surgery. Secondary objectives include describing perioperative plasma concentrations, assessing pharmacokinetic variability, identifying factors associated with target non-attainment, and comparing outcomes between surgical subgroups.\n\nThis study aims to provide clinically relevant data to assess the adequacy of current prophylactic dosing strategies and to support potential optimization of antibiotic administration in high-risk surgical patients.",[25,26,27],"Antibiotic Prophylaxis","Pancreatic Surgey","Hepatic Surgery",[29,30,31],"PK\u002FPD target atttainment","piperacillin","surgical site infection","NOT_YET_RECRUITING","2026-04-27",{"date":35,"type":36},"2026-04-30","ACTUAL",{"date":38,"type":21},"2026-05-01",{"date":40,"type":21},"2027-05-01",{"name":42,"class":43},"Central Hospital, Nancy, France","OTHER"]
