Robotic thyroidectomy versus endoscopic thyroidectomy: a meta-analysis

摘要

BACKGROUND: To conduct a meta-analysis to determine the relative merits of robotic thyroidectomy (RT) and endoscopic thyroidectomy (ET). METHODS: A literature search was performed to identify comparative studies reporting peri-operative outcomes for RT and ET. Pooled odds ratios (ORs) and weighted mean differences (WMDs) with 95% confidence interval (95% CI) were calculated using either a fixed-effects or a random-effects model. RESULTS: Six studies matched the selection criteria, which reported on 2048 subjects, of whom 978 underwent RT and 1070 underwent ET. Comparing the outcomes of RT with ET, this meta-analysis indicated that RT was associated with more complications (WMD = 1.51, 95% CI 1.18 to 1.94) and greater amount of drainage fluid (WMD = 17.10, 95% CI 5.69 to 28.51). Meanwhile, operating time (WMD = 1.50, 95% CI -39.59 to 42.58), conversion (WMD = 0.63, 95% CI 0.07 to 6.17), post-operative hospital stay (WMD = -0.05; 95% CI -0.18 to 0.08), and the number of lymph nodes harvested (WMD = 0.62, 95% CI -0.29 to 1.53) were similar for both procedures. CONCLUSION: The results of this meta-analysis indicated that RT is associated with an increased risk of complications and a greater amount of drainage fluid. Therefore, RT does not appear to have any advantage over ET. Further studies are required to confirm these results.
