Background:
The impact of preoperative biliary drainage (PBD) on perioperative morbidity and mortality in pancreatic surgery is still under debate. The aim of this study was to investigate outcomes of stented vs. non-stented patients undergoing pancreatoduodenectomy (PD).
Methods:
We retrospectively compared 500 consecutive patients who underwent PBD prior to PD with 500 patients who did not. Ninety-day mortality and morbidity were assessed.
Results:
The overall postoperative morbidity and mortality was 37% and 1.4%, respectively. Major complications (Clavien ≥ III) occurred in 16% of patients. The overall morbidity and mortality was not significantly higher in patients who underwent PBD. However, the rate of wound infection was significantly higher in patients who underwent PBD (19% vs. 9%, P = 0.001). When comparing intraoperative bile cultures of stented patients with and without wound infection, the presence of Enterobacter species (OR 2.4, 95% CI 1.5-4.1, P = 0.001) and Citrobacter species (OR 2.3, 95% CI 1.1-5.2, P = 0.037) in the bile significantly increased the likelihood of wound infection.
Conclusion:
Preoperative biliary drainage is associated with bactobilia and wound infection, but does not affect the overall morbidity and mortality of patients undergoing PD.
