Mortality Rates in Benign Laparoscopic and Robotic Gynecologic Surgery: A Systematic Review and Meta-analysis.

OBJECTIVE: To review mortality rates in benign gynecologic minimally invasive laparoscopic and robotic surgery (MIS) and the rates associated with commonly performed MIS procedures. DATA SOURCES: An electronic-based search was performed on PubMed, Embase, Scopus, Web of Science, and Cochrane Database for articles published in the last 10 years in English, French, German, Spanish, and Italian. METHODS OF STUDY SELECTION: All MIS articles in benign gynecology reporting operative mortality (within 30 days) were reviewed. TABULATION, INTEGRATION, AND RESULTS: The articles identified through the aforementioned search criteria were independently evaluated by the first 2 authors. The Newcastle-Ottawa scale for observational studies and Cochrane risk-of-bias assessment tool for randomized controlled trials were used to assess the risk of bias. Meta-analysis was applied to calculate pooled mortality rates using the inverse-variance method. Twenty-one articles (124 216 patients) were included. Operative mortality from any benign MIS (laparoscopy and robotics) procedure was 1:6456 (95% confidence interval [CI]: 1:3946-1:10 562). Studies were then grouped based on the surgical procedure. The mortality rate for hysterectomy (119 721 patients), sacrocolpopexy, and adnexal surgery and diagnostic laparoscopy was 1:6814 (95% CI: 1:4119-1:11 275), 1:1246 (95% CI: 1:36-1:44 700), and 1:2245 (95% CI: 1:45-1:113 372), respectively. Eighteen articles reported operative mortality for laparoscopic surgery and 4 for robotic surgery. CONCLUSION: Operative mortality in benign minimally invasive gynecologic surgery is low, and mortality for laparoscopic and robotic approaches appears to be similar.
