Clinical Scorecard: Evaluation of an Improved Anti-Infection Prophylaxis Protocol for Pancreatoduodenectomy: A Single-Center Study
At a Glance
Category
Detail
Condition
Postoperative infections including surgical site infections (SSI) after pancreatoduodenectomy (PD)
Key Mechanisms
Targeted perioperative antibiotic prophylaxis based on local resistance patterns combined with extended intraoperative peritoneal lavage (EIPL) and selective decontamination of the digestive tract (SDD) to reduce SSI
Target Population
Patients undergoing pylorus-preserving or classic pancreatoduodenectomy for pancreatic head, distal bile duct, or ampullary tumors
Care Setting
Surgical and perioperative care in a high-volume tertiary hospital setting
Key Highlights
Pancreatoduodenectomy carries a high morbidity rate (30–60%) with SSI incidence of 10–30%, significantly higher than general abdominal surgery.
Preoperative bile duct interventions alter microbiome and increase risk of resistant bacterial infections, necessitating targeted antibiotic prophylaxis.
Combination of targeted antibiotics (piperacillin/tazobactam), extended intraoperative peritoneal lavage with saline, and selective digestive tract decontamination reduces septic complications.
Guideline-Based Recommendations
Diagnosis
Use CDC definitions for surgical site infection (SSI).
Classify postoperative complications using Clavien-Dindo Classification.
Define postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), and postpancreatectomy hemorrhage (PPH) per ISGPS consensus.
Management
Administer targeted perioperative antibiotic prophylaxis based on local resistance patterns (e.g., piperacillin/tazobactam).
Perform extended intraoperative peritoneal lavage with five liters of saline after reconstruction during PD.
Implement selective decontamination of the digestive tract (vancomycin, colistin, tobramycin, amphotericin B) preoperatively.
Apply WHO-recommended surgical site infection prevention measures including alcohol-based antiseptic skin preparation and povidone-iodine irrigation of subcutaneous tissue.
Monitoring & Follow-up
Monitor for septic complications within 90 days post-surgery.
Assess morbidity and mortality using standardized classifications and definitions.
Perform intraoperative bile duct swab for microbiological examination.
Risks
High risk of SSI due to altered bile duct microbiome and resistant bacteria after preoperative bile duct interventions.
SSI increases hospital stay, reoperation rates, mortality, and healthcare costs.
Patient & Prescribing Data
163 patients undergoing pylorus-preserving or classic pancreatoduodenectomy between 2018 and 2021
Patients receiving targeted antibiotic prophylaxis with piperacillin/tazobactam, extended peritoneal lavage, and SDD showed reduced incidence of superficial and intraabdominal SSI compared to standard prophylaxis with cefuroxime and metronidazole.
Clinical Best Practices
Tailor perioperative antibiotic prophylaxis to local bacterial resistance patterns.
Incorporate extended intraoperative peritoneal lavage with saline to reduce bacterial load.
Use selective digestive tract decontamination preoperatively to minimize septic complications.
Adhere strictly to WHO guidelines for surgical site infection prevention including antiseptic skin preparation and wound handling.
Collect intraoperative bile duct cultures to guide postoperative antibiotic therapy.
