Abstract

A systematic review and meta-analysis of randomized controlled trials was performed to estimate the effects on surgical outcomes of pretreatment with gonadotropin-releasing hormone (GnRH) agonist before laparoscopic myomectomy. The electronic bibliographic databases MEDLINE, EMBASE, Web of Knowledge, Scopus, and Cochrane Library, and reference lists from relevant articles were searched for English-language publications describing randomized controlled trials of GnRH agonist pretreatment vs placebo or no treatment before laparoscopic myomectomy. Three studies including 168 participants were identified. Pretreatment with GnRH agonist did not reduce operative time; however, intraoperative blood loss was statistically lowered (mean difference, 60 mL; 95% confidence interval [CI], 39-82). Statistical difference was also observed in postoperative hemoglobin concentration (mean difference, 1.15 g/dL; 95% CI, 0.46-1.83]) and red blood cell count (mean difference, 0.65 × 10(6) cells/mL; 95% CI, 0.16-1.14]) but not serum iron concentration. None of the patients in the studies experienced any major intraoperative or postoperative complications, and only 1 patient in each group required blood transfusion. This study does not show a difference in operative time with GnRH agonist pretreatment, which clarifies the previous conflicting reports on the effect of GnRH agonist therapy on the duration of laparoscopic myomectomy. Furthermore, despite previously reported decreased bleeding conferred by the laparoscopic approach compared with laparotomy, this meta-analysis demonstrates a further reduction in intraoperative blood loss with GnRH agonist pretreatment in patients undergoing laparoscopic myomectomy. Additional high-quality studies with appropriate power and follow-up are needed to corroborate these findings and to evaluate the treatment effects on short- and long-term outcomes such as perioperative complications and fertility.
