Background
Optimal preoperative biliary drainage for patients with pancreatic cancer before pancreatoduodenectomy remains unclear. This study aimed to investigate the comparison of efficacy and safety between a metallic stent (MS) and a plastic stent (PS).
Methods
Comparative studies on the use of MS and PS for pancreatic cancer before pancreatoduodenectomy were systematically searched using the MEDLINE and Web of Science databases. Pre- and postoperative data also were extracted. Random-effects meta-analyses were performed to compare post-endoscopic retrograde cholangiopancreatography (ERCP) complications as well as intra- and postoperative outcomes between the two arms of the study, and pooled odds ratios (ORs) or mean differences (MDs) were calculated with 95 percent confidence intervals (CIs).
Results
The study analyzed 12 studies involving 683 patients. Insertion of MS was associated with a lower incidence of re-intervention (OR, 0.06; 95% CI 0.03–0.15; P < 0.001), increased post-ERCP adverse events (OR, 2.22; 95% CI 1.13–4.36; P = 0.02), and similar operation time (MD, 18.0 min; 95% CI –29.1 to 65.6 min; P = 0.46), amount of blood loss (MD, 43.0 ml; 95% CI –207.1 to 288.2 ml; P = 0.73), and surgical complication rate (OR, 0.78; 95% CI 0.53–1.15; P = 0.21). The cumulative stent patency rate after 3 months was higher in the MS group than in the PS group (70–100 % vs 30.0–45.0 %).
Conclusion
For biliary drainage in patients with pancreatic cancer during this era of multidisciplinary treatment, MS use might be the first choice because MS provides a more durable biliary drainage and a similar risk of postoperative outcomes compared with PS.
