Subgroup analysis: robotic
Three studies included robotic surgery. Similar to the overall
population, the robotic approach was as safe as the MS approach with
similar early post-operative outcomes (supplementary table 3); LOS was
significantly reduced in the robotic group (SMD -0.91, 95% CI -1.58,
-0.24, p<.01), yet heterogeneity was detected
(p<0.01); given the limited robotic sample size, no analysis
at follow-up could be carried out.
