Abstract

Background: Pancreaticoduodenectomy can entail a high complication rate, especially in patients who underwent preoperative bile duct drainage through bile duct stenting. Pancreaticoduodenectomy bile duct stenting patients frequently receive prophylactic antibiotic therapy in the postoperative period. However, the exact value and the benefit of prophylactic antibiotic therapy in pancreaticoduodenectomy bile duct stenting patients remains under-investigated and thus unclear. Method: We conducted a retrospective single-center study of pancreaticoduodenectomy bile duct stenting patients between January 2007 and December 2022. Demographic, clinical, laboratory, and pathology data of 370 patients were collected, and intraoperative swab cultures of the bile were obtained from all patients upon transection of the common bile duct. The groups to be investigated were formed on the basis of postoperative antibiotic prophylaxis. Postoperative complications and antibiotic resistance analysis were recorded. Results: Postoperative antibiotic prophylaxis in stented patients after pancreaticoduodenectomy significantly reduced major complications (odds ratio: 0.547 [95% confidence interval 0.327–0.915]; P = .02) such as reoperation (P = .041) and readmission to the intensive care unit (P = .037). Patients with Enterococcus faecalis (odds ratio: 1.699 [95% confidence interval 0.978–2.950];P = .048), Enterococcus faecium (odds ratio: 1.808 [95% confidence interval 1.001–3.264]; P = .050), or Citrobacter (odds ratio: 2.211 [95% confidence interval 1.087–4.497]; P = .029) in their bile had a higher probability of developing wound infections. Appropriate antibiotic prophylaxis, according to the bile duct microbiome, significantly reduced the risk of wound infection (odds ratio: 2.239 [95% confidence interval 1.167–4.298]; P = .015). Conclusion: Postoperative antibiotic prophylaxis in pancreaticoduodenectomy bile duct stenting patients significantly reduced major complications such as intensive care stay and reoperation. Targeted antibiotic treatment according to the biliary microbiome reduced the incidence of wound infections.
