Abstract We conducted a systematic review and meta-analysis to assess the safety and effectiveness of robotic vs laparoscopic hysterectomy in women with benign uterine disease, as determined by randomized studies. We searched MEDLINE, EMBASE, the Cochrane Library, ClinicalTrials.gov , and Controlled-Trials.com from study inception to October 9, 2014, using the intersection of the themes “robotic” and “hysterectomy.” We included only randomized and quasi-randomized controlled trials of robotic vs laparoscopic hysterectomy in women for benign disease. Four trials met our inclusion criteria and were included in the analyses. We extracted data, and assessed the studies for methodological quality in duplicate. For meta-analysis, we used random effects to calculate pooled risk ratios (RRs) and weighted mean differences. For our primary outcome, we used a modified version of the Expanded Accordion Severity Grading System to classify perioperative complications. We identified 41 complications among 326 patients. Comparing robotic and laparoscopic hysterectomy, revealed no statistically significant differences in the rate of class 1 and 2 complications (RR, 0.66; 95% confidence interval [CI], 0.23–1.89) or in the rate of class 3 and 4 complications (RR, 0.99; 95% CI, 0.22–4.40). Analyses of secondary outcomes were limited owing to heterogeneity, but showed no significant benefit of the robotic technquie over the laparoscopic technique in terms of length of hospital stay (weighted mean difference, −0.39 day; 95% CI, −0.92 to 0.14 day), total operating time (weighted mean difference, 9.0 minutes; 95% CI, −31.27 to 47.26 minutes), conversions to laparotomy, or blood loss. Outcomes of cost, pain, and quality of life were reported inconsistently and were not amenable to pooling. Current evidence demonstrates neither statistically significant nor clinically meaningful differences in surgical outcomes between robotic and laparoscopic hysterectomy for benign disease. The role of robotic surgery in benign gynecology remains unclear.
