Abstract: Objective: To evaluate the efficacy and safety of preoperative biliary drainage (PBD) compared to immediate surgery (IS) in patients with resectable pancreatic ductal adenocarcinoma and obstructive jaundice. Methods: Systematic review and meta-analysis of randomized controlled trials (RCTs) identified in PubMed, EMBASE, and Cochrane databases. Quantitative synthesis used the DerSimonian-Laird random-effects model in R Studio software. The primary outcome was severe postoperative morbidity (Clavien-Dindo >= III). Results: Four RCTs involving 419 patients were included. The meta-analysis demonstrated that PBD is associated with a significantly higher risk of severe complications (RR 1.71; 95% CI: 1.38-2.12; p < 0.0001) and surgical site infections (RR 2.68; 95% CI: 1.77-4.07), with no reduction in 30-day mortality. Conclusion: Immediate surgery should be the standard of care for resectable pancreatic head cancer. Preoperative biliary drainage should be limited to cases of acute cholangitis or when surgical delay exceeds four weeks, given the significant increase in infectious morbidity without survival benefit.
