Abstract | INTRODUCTION:
Metal stenting can be used as a primary treatment option for alleviating malignant hilar biliary obstruction (MHBO) symptoms. Although many studies have focused on the topic of unilateral or bilateral stenting for MHBO, there is a clear need for a study comparing these two stenting types in patients with a single type of cancer. AIM: MATERIAL AND METHODS: The PubMed, Embase, and Cochrane Library databases were searched to identify all relevant studies. This meta-analysis was conducted using RevMan v5.3. RESULTS: We initially identified 154 studies, seven of which were included in the final meta-analysis. These studies contained 524 HCCA patients treated by either unilateral (n = 215) or bilateral (n = 309) stent insertion. No significant differences were observed between groups in rates of technical success (OR = 0.93; 95% CI: 0.34-2.54, p = 0.88), clinical success (OR = 1.03; 95% CI: 0.49-2.15, p = 0.94), stent dysfunction (OR = 1.47; 95% CI: 0.91-2.39, p = 0.12), or survival (HR = 0.85; 95% CI: 0.50-1.42, p = 0.53). However, the unilateral group exhibited significantly lower complication rates (OR = 0.34; 95% CI: 0.13-0.88, p = 0.03). Significant heterogeneity was found in the endpoint of survival. Funnel plot analysis did not suggest any publication bias relating to the selected study endpoints. CONCLUSIONS: Compared to bilateral metal stenting, unilateral metal stenting could provide a similar clinical efficacy for patients with HCCA with a lower complication rate.
