Effects of Pre_Operation Desogestrel Estradiol in Endometrial Preparation at Hysteroscopic Polypectomy

Abstract

Background: Hysteroscopic surgery is a common gynecologic process in many conditions. Endometrial thinning is the main successful key for this process associated with many preoperative preparations. This study aimed to evaluate DE (Desogestrel-estradiol) to reduce endometrial thickness in comparison with the control group. Materials and Methods: This Randomized clinical trial was done on the patients candidate for polypectomy that were randomly divided into two groups of intervention and control; the first group received DE OCP (oral contraceptive pill with 30 microgram Ethinyl estradiol + 150 micro gram Desogestrel) once daily from the 1st to 5th day of the menstrual cycle for 21 days and then in the first day of next menstruation cycle, the drug was used up to one day before hysteroscopy done in the 5th to 8th day of the cycle. The second group received no drugs. Hysteroscopy was done in the early follicular phase in both groups and all the subjects received one dosage of Misoprostol a night before surgery. Results: There were no significant differences between the parity, polyp size, and BMI (Body Mass Index) in the two groups. The mean duration of surgery, mean endometrial thickness before hysteroscopy, the quality of endometrial tissue, and surgeon satisfaction were significantly difference between the two groups. However, the quality of the surgeon’s vision in the intervention group was better than the control group but there was no significant difference between the two groups. Conclusion: Pre-operation endometrial thinning by oral contraceptives such as DE could be an effective method and reduce the duration of surgery.
