Combined Laparoscopic Uterine Artery Occlusion and Myomectomy versus Laparoscopic Myomectomy: A Direct-Comparison Meta-Analysis of Short- and Long-Term Outcomes in Women with Symptomatic Leiomyomas

To ascertain the efficacy and safety of laparoscopic uterine artery occlusion (LUAO) during laparoscopic myomectomy (LM) on intra- and postoperative morbidity and to assess its impact on leiomyoma recurrence rates. MEDLINE, Scopus, Web of Science, and Cochrane Database were searched for relevant references from inception until December 2018, in line with PRISMA guidelines. Two authors screened for study eligibility and extracted data. Randomized controlled trials (RCTs) and observational studies (OSs) comparing short- and long-term morbidity of LM with or without LUAO were included. The modified Jadad score and the methodologic index for nonrandomized studies were used to evaluate the quality of RCTs and OSs, respectively. Twelve studies encompassing 750 LM and 873 LUAO-LM cases were included in the meta-analysis. The studies were of moderate quality. LUAO-LM appears to significantly decrease intraoperative blood loss, postoperative hemoglobin drop, and blood transfusion rate. A trend toward shorter hospital length of stay was demonstrated, whereas no significant difference in operation duration was observed. The combined procedure seemingly contributes to lower recurrence rate. No LUAO-related complications were reported. Moderate to high heterogeneity was observed for few outcomes. This is the first meta-analysis to date to provide a convincing overview of efficacy and safety of LUAO-LM. Although a medium risk of bias warrants some caution with interpretation of the results, LUAO-LM seemingly improves intra- and postoperative outcomes in women with symptomatic leiomyomas.
