Purpose: the aim of the present study was to evaluate the role of hysteroscopic endometrial ablation in the treatment of menorrhagia. Methods: two hundred patients were submitted to hysteroscopic endometrial ablation between April 1991 and April 1999. The surgery was performed in a private hospital under spinal anesthesia. In the first four years we used 1.5% glycine as a distension medium and in the last four years we used mannitol 3%. The follow-up ranged from 8 months to 8 years. Results: relief of the symptomatology was achieved in 180 (90%) patients. One episode of uterine perfuration, two cases of moderate liquid overload and five of hematometra were recorded. The histologic evaluation of the resected endometrium showed proliferative activity in 104 patients (52%) and secretory activity in 34 (17%). Endometrial hyperplasia was found in 20 patients (10%). The patients submitted to resection showed a smaller uterine cavity and fibrous synechia, whereas in patients submitted to endometrial destruction the uterine cavity was small but without synechia. Two patients had moderade hypervolemia during the procedure, for which clinical treatment was successful. Conclusions: Hysteroscopic endometrial ablation showed to be a safe and effective procedure as treatment of menorrhagia.
