Clinical Report: Improved Anti-Infection Prophylaxis Reduces SSI After Pancreatoduodenectomy
Overview
This single-center study evaluated the impact of a targeted antibiotic prophylaxis protocol combined with extended intraoperative peritoneal lavage (EIPL) and selective digestive tract decontamination (SDD) on surgical site infections (SSI) after pancreatoduodenectomy (PD). The improved protocol significantly reduced the incidence of SSI and other septic complications compared to standard prophylaxis.
Background
Pancreatoduodenectomy (PD) is the only curative option for tumors of the pancreatic head, distal bile duct, or ampulla but carries a high morbidity rate of 30–60%, largely due to postoperative complications including surgical site infections (SSI). SSI after PD occurs in 10–30% of patients, substantially increasing hospital stay, reoperation rates, mortality, and healthcare costs. Preoperative bile duct interventions alter the bile microbiome, often leading to resistant bacterial colonization and higher septic complication rates. Targeted perioperative antibiotic prophylaxis based on local resistance patterns, combined with extended intraoperative peritoneal lavage (EIPL) and selective digestive tract decontamination (SDD), may reduce SSI incidence and improve outcomes.

Key Findings
The improved anti-infection prophylaxis protocol (EAP group) using piperacillin/tazobactam, EIPL, and SDD significantly reduced SSI incidence from 27% to 11% compared to standard prophylaxis.
Intraabdominal abscess rates decreased from 19% in the control group to 8% in the EAP group.
Postoperative pancreatic fistula rates were lower in the EAP group (15%) versus control (22.2%).
Median hospital stay was reduced by 5 days in the EAP group (18 days) compared to control (23 days).
90-day mortality was reduced from 6.3% in the control group to 3.0% in the EAP group.
Targeted antibiotic prophylaxis based on local resistance patterns effectively addressed resistant Enterobacter and Enterococcus species frequently found after bile duct interventions.
Clinical Implications
Implementing a targeted perioperative antibiotic regimen tailored to local microbial resistance, combined with extended intraoperative peritoneal lavage and selective digestive tract decontamination, can significantly reduce SSI and other septic complications after pancreatoduodenectomy. These measures may shorten hospital stays and reduce mortality, improving overall patient outcomes and potentially lowering healthcare costs.
Conclusion
The study demonstrates that an improved anti-infection prophylaxis protocol incorporating targeted antibiotics, EIPL, and SDD effectively decreases surgical site infections and postoperative morbidity after pancreatoduodenectomy. Adoption of such protocols may enhance perioperative management and patient recovery in pancreatic surgery.
