The authors report the results of their experience of hysteroscopic endometrial reduction through a retrospective series of 85 patients who underwent surgery between October 1988 and February 1991. The indication consisted of hemorrhage (menorrhagia and metrorrhagia) of endometrial origin in women with a group mean age of 46 years who had no intention of becoming pregnant in the future. The pre-treatment assessment was based on diagnostic hysteroscopy and was intended to eliminate neoplasm of the endometrium or its precursors. The endometrial reduction procedure always preserved an isthmic ring of endometrial tissue. No peroperative complication was reported. The mean duration of surgery was about 39 minutes. With a follow-up period of more than one year, bleeding had disappeared in 78% of cases. The authors conclude that the technic of endometrial resection in the treatment of benign lesions of the endometrium, on condition that the possibility of any disorder calling for laparotomy is ruled out and that there is regular postoperative follow-up.
