QIU Mei-ying

Abstract：Objective:To investigate the recurrence-prevention effect of oral Desogestrel and Ethinylestradiol Tablets(Marvelon) or Levonorgestrel-releasing Intrauterine System(Mirena) after hysteroscopic endometrial polypectomy.Method:247 patients who received hysteroscopic endometrial polypectomy and were confirmed with endometrial polyp by postoperative pathological examination,were enrolled into this study.The patients were divided into three groups. Marvelon group(n=84) was given Marvelon Tablets three to six months after the operation.Mirena group (n=81) received Levonorgestrel-releasing Intrauterine System after the operation.And control group(n=82) received no treatment after hysteroscopic endometrial polyectomy.The three groups were followed 12 months after the procedure,and the recurrence rate and menstruation of three groups were compared.Result:The recurrence rate of marvelon group was 5.95%,mirena group was 3.70%,control group was 18.29%,control group had significantly higher recurrence rate than marvelon group and mirena group(P<0.05).There was no statistical significance between marvelon group and mirena groups(P>0.05).The control group had lower proportion of low menstruation volume in three,six,twelve months after the operation than marvelon and mirena group(P<0.01).Conclusion:Oral Marvelon tablets or Levonorgestrel-releasing Intrauterine System after hysteroscopy for endometrial polys siginificantly decreases the recurrence rate and the menstruation volume.
