Gonadotrophin-releasing hormones agonist therapy increases peritoneal fibrinolytic activity and prevents adhesion formation after myomectomy

The aim of this study was to evaluate uterine adhesions after myomectomy and peritoneal fibrinolytic capacity in women treated with gonadotrophin-releasing hormone agonist (GnRHa) before surgery. A prospective observational study comprised 15 infertile women who underwent myomectomy. Before surgery, 10 were treated with buserelin acetate (900 μg/day) for 10 – 12 weeks followed by additional postoperative treatment with GnRHa for 4 weeks (GnRHa group) and five received no treatment (control group). Peritoneal fluid specimens were taken at the beginning of myomectomy and the adhesions were estimated by second-look surgery (caesarean section or laparoscopy). Levels of plasminogen activator (PA) and PA inhibitor (PAI) were determined by enzyme-immunosorbent assays. Pre- and postoperative GnRHa therapy significantly reduced adhesion formation compared with control groups (adhesion scores; 0.2 ± 0.4 vs. 2 ± 1, P < 0.0001). GnRHa group showed a significant decrease in PAI level (P < 0.0001) but no significant ch...
