Prolonged antibiotics after pancreatoduodenectomy reduce abdominal infections in patients with positive bile cultures: a dual-center cohort study

Article / Letter to editor
Background: Abdominal infections account for substantial morbidity after pancreatoduodenectomy. Contaminated bile is the presumed main risk factor, and prolonged antibiotic prophylaxis might prevent these complications. This study compared organ/space infection (OSIs) rates in patients receiving perioperative versus prolonged antibiotic prophylaxis after pancreatoduodenectomy.Methods: Patients undergoing pancreatoduodenectomy in two Dutch centers between 2016 and 2019 were included. Perioperative prophylaxis was compared prolonged prophylaxis (cefuroxime and metronidazole for five days). The primary outcome was an isolated OSI: an abdominal infection without concurrent anastomotic leakage. Odds ratios (OR) were adjusted for surgical approach and pancreatic duct diameter.Results: OSIs occurred in 137 out of 362 patients (37.8%): 93 patients with perioperative and 44 patients with prolonged prophylaxis (42.5% versus 30.8%, P = 0.025). Isolated OSIs occurred in 38 patients (10.5%): 28...Show moreBackground: Abdominal infections account for substantial morbidity after pancreatoduodenectomy.

Isolated OSIs occurred in 38 patients (10.5%): 28 patients with perioperative and 10 patients with prolonged prophylaxis (12.8% versus 7.0%, P = 0.079). Bile cultures were obtained in 198 patients (54.7%). Patients with positive bile cultures showed higher isolated OSI rates with perioperative compared to prolonged prophylaxis (18.2% versus 6.6%, OR 5.7, 95% CI: 1.3-23.9).Conclusion: Prolonged antibiotics after pancreatoduodenectomy are associated with fewer isolated OSIs in patients with contaminated bile and warrant confirmation in a randomised controlled trial (Clinicaltrials.gov NCT0578431).Show less
