RESUMEN
BACKGROUND: As resources into gynecological surgical simulation training increase, research showing an association with improved clinical outcomes is needed. OBJECTIVE: To evaluate the association between surgical simulation training for total laparoscopic hysterectomy (TLH) and rates of intraoperative vascular/visceral injury (primary outcome) and operative time. SEARCH STRATEGY: We searched Medline OVID, Embase, Web of Science, Cochrane, and CINAHL databases from the inception of each database to April 5, 2022. Selection Critera: Randomized controlled trials (RCTs) or cohort studies of any size published in English prior to April 4, 2022. DATA COLLECTION AND ANALYSIS: The summary measures were reported as relative risks (RR) or as mean differences (MD) with 95% confidence intervals using the random effects model of DerSimonian and Laird. A Higgins I2 >0% was used to identify heterogeneity. We assessed risk of bias using the Cochrane Risk of Bias tool 2.0 (for RCTs) and the Newcastle Ottawa Scale (for cohort studies). MAIN RESULTS: The primary outcome of this systematic review and meta-analysis was to evaluate the impact of simulation training on the rates of vessel/visceral injury in patients undergoing TLH. Of 989 studies screened 3 (2 cohort studies, 1 randomized controlled trial) met the eligibility criteria for analysis. There was no difference in vessel/visceral injury (OR 1.73, 95% CI 0.53-5.69, p=0.36) and operative time (MD 13.28, 95% CI -6.26 to 32.82, p=0.18) when comparing before and after simulation training. CONCLUSION: There is limited evidence that simulation improves clinical outcomes for patients undergoing TLH.
