Özet
Background: Endoluminal radiofrequency ablation (RFA) is a palliative treatment for patients suffering from malignant biliary obstruction (MBO). We aimed to conduct a meta-analysis to evaluate the impact of RFA on stent patency, patient survival, and adverse events. Methods: Major databases were searched through December 2023 for patients who had undergone stenting with or without RFA for extrahepatic MBO. A random-effects model was used for analysis, with results expressed as relative risk ratios (RRs) with 95%CIs. Results: Nine RCTs involving 750 subjects with MBO (374 RFA plus stent vs. 376 stent only) were included. Meta-analysis revealed similar risks of stent patency at 3 months (RR 1.01, 95%CI 0.92-1.11; I (2) = 4%) for RFA plus stenting vs. stent only. Meta-analysis showed improved survival at 6 months (RR 0.84, 95%CI 0.73-0.96; I (2) = 21%; P = 0.01) for RFA plus stenting vs. stent only. Subgroup analysis comparing plastic vs. uncovered metal stents showed that stent patency was unaffected at 3 months (RR 1.06, 95%CI 0.91-1.23; I (2) = 17%). Subgroup analysis showed that patients with cholangiocarcinoma experienced an overall survival benefit with RFA plus stenting vs. stenting alone (P < 0.001); however, stent patency remained unaffected (P = 0.08). An increased incidence of cholecystitis was noted with RFA plus stenting vs. stenting alone (5.1% [95%CI 3.1%-7.8%] vs. 0.3% [95%CI 0.01%-1.5%], respectively). Conclusion: Combining endoluminal RFA and stenting may improve overall survival in patients with MBO. RFA did not significantly impact stent patency.
