The Comparison of Gonadotropin-Releasing Hormone Agonist Therapy and Intraperitoneal Ringer's Lactate Solution in Prevention of Postoperative Adhesion Formation in Rat Models

Abstract

Objective: To evaluate gonadotropin-releasing hormone agonists (GnRH-a) therapy and intraperitoneal Ringer's lactate solution (RL) for the prevention of postsurgical adhesion formation in rat models.Study Design: Forty rats were randomized into four groups: Group I was the control; in group II, RL was applied at the surgery; group III and IV received preoperative subcutaneous injections of the GNRH-a leuprolide acetate and only the diluent of the GNRH-a respectively. A standard lesion was created over the uterus of each rat. Adhesions were scored at relaparotomy 3 weeks later. Analysis of variance (Kruskal-Wallis) and Mann-Whitney U-tests were used for the statistical evaluation.Results: The average adhesion scores were 2.7±0.26, 1.4±0.27, 0.9±0.18, and 2.5±0.34 in groups I, II, III, and IV respectively. There were significant differences between the scores of groups I and II (P<0.01), groups I and III (P<0.001), groups II and IV (P<0.05), and groups III and IV (P<0.01); but not between the scores of groups II and III, and groups I and IV (P>0.05).Conclusion: GNRH-a was successful in reducing postoperative adhesion formation but was not superior to intraperitoneal RL.
