Preoperative medical treatment with danazol or GnRHa reduced intraoperative fluid absorption and operating time for hysteroscopic endometrial resection, myomectomy, and metroplasty, with GnRHa also showing a trend toward increased amenorrhea.

Abstract

The evidence of the efficacy of preoperative medical treatment with danazol, gonadotrophin releasing-hormone agonists (GnRHa) or progestins in facilitating surgery and improving the long-term results of myomectomy, hysteroscopic metroplasty and endometrial resection has been reviewed. Sixteen randomized and non-randomized controlled clinical trials, published in the English literature between 1990 and 1996, were identified. In all studies comparing GnRHa or danazol versus no treatment, fluid absorption during surgery was less in subjects who underwent medical treatment independently of the drug used and the type of intervention, the reduction ranging from 142 to 572 ml. A reduction in operating time (between 2 and 25 min) was observed in both the danazol and GnRHa-treated groups in comparison with untreated controls, regardless of the type of operation (endometrial resection, myomectomy or metroplasty). With regard to long-term results, amenorrhoea tended to be more frequent in patients who received GnRHa: the pooled odds ratio (OR) of amenorrhoea for GnRHa-treated women compared with untreated controls was 2.0 [95% confidence interval (CI), 1.1-3.8]. In studies comparing GnRHa with danazol, no marked differences were observed in mean operating time, but the OR of amenorrhoea at 6-12 months after surgery was 1.9 (95% CI 1.0-3.3).
