Systematic review and meta-analysis of vaginal natural orifice transluminal endoscopic surgery vs laparoscopic hysterectomyAJOG Global Reports at a Glance
Abstract
OBJECTIVE: Because vaginal natural orifice transluminal endoscopic surgery and laparoscopic hysterectomy techniques both aim to decrease tissue injury and postoperative morbidity and mortality and to improve a patient's quality of life, we sought to evaluate the safety and effectiveness of a hysterectomy by vaginal natural orifice transluminal endoscopic surgery and compared that with conventional laparoscopic hysterectomy among women with benign gynecologic diseases. DATA SOURCES: We used Scopus, Medline, ClinicalTrials.Gov, PubMed, and the Cochrane Library and searched from database inception to September 1, 2023. STUDY ELIGIBILITY CRITERIA: We included all eligible articles that compared vaginal natural orifice transluminal endoscopic surgery hysterectomy with any conventional laparoscopic hysterectomy technique without robotic assistance for women with benign gynecologic pathology and that included at least 1 of our main outcomes. These outcomes included estimated blood loss (in mL), operation time (in minutes), length of hospital stay (in days), decrease in hemoglobin level (g/dL), visual analog scale pain score on postoperative day 1, opioid analgesic dose required, rate of conversion to another surgical technique, intraoperative complications, postoperative complications, and requirements for blood transfusion. We included randomized controlled trials and observational studies. Ultimately, 14 studies met our criteria. METHODS: The study quality of the randomized controlled trials was assessed using the Cochrane assessment tool, and the quality of the observational studies was assessed using the ROBINS-I tool. We analyzed data using RevMan 5.4.1. Continuous outcomes were analyzed using the mean difference and 95% confidence intervals under the inverse variance analysis method. Dichotomous outcomes were analyzed using OpenMeta[Analyst] and odds ratios and 95% confidence intervals were reported. RESULTS: The operative time and length of hospitalization were shorter in the vaginal natural orifice transluminal endoscopic surgery cohort. We also found lower visual analog scale pain scores, fewer postoperative complications, and fewer blood transfusions in the vaginal natural orifice transluminal endoscopic surgery group. We found no difference in the estimated blood loss, decrease in hemoglobin levels, analgesic usage, conversion rates, or intraoperative complications. CONCLUSION: When evaluating the latest data, it seems that vaginal natural orifice transluminal endoscopic surgery techniques may have some advantages over conventional laparoscopic hysterectomy techniques.
