Duration of Perioperative Antibiotics in Pancreatoduodenectomy

The goal of this clinical trial is to compare two perioperative antibiotic prophylaxis regimens in adult patients undergoing pancreatoduodenectomy (PD) or pylorus-preserving pancreatoduodenectomy (PPPD). The main question it aims to answer is: Is a single preoperative dose of cefazolin non-inferior to the conventional extended regimen (preoperative cefoxitin followed by 3 days of postoperative cefotaxime plus metronidazole) in preventing surgical site infection? Researchers will compare the single-dose cefazolin regimen with the conventional extended regimen to determine whether the shorter regimen results in a comparable rate of postoperative surgical site infection. Participants will be randomized 1:1 to one of the two regimens and followed for 30 days after surgery for surgical site infection and other infectious complications.
