Objective.A retrospective study of short and long term results of transcervical endomyometrial resection for menorrhagia.Material and methods.Patient data were collected from all 104 premenopausal women who had undergone a transcervical endomyometrial resection due to severe menorrhagia in 1990-95. Almost 40% had submucous fibromas that were resected together with the endometrium. A questionnaire about gynecological symptoms was mailed to all 104 women. Ninety-seven (93%) women answered the questionnaire.Results.The mean follow-up period was 29 months. The following short-term complications were encountered: fluid overload in four, one uterine perforation and one major bleeding. The long-term complications included: three hematometra and one pregnancy ending in a spontaneous abortion. Glandular hyperplasia of the endometrium without atypia was found in two cases, and adenomyosis in 31 (29%) cases. Twenty-one women (21%) became amenorrhoic after the treatment, whereas forty-nine (51%) had minimal menstrual bleeding. Eleven women (11%) suffered from dysmenorrhea. Due to dysmenorrhea and/or persistent menorrhagia thirteen (12.5%) underwent a hysterectomy, generally within one year after the resection. The histological examinations showed adenomyosis in three cases, fibromas in four and fibromas and adenomyosis in three cases.Conclusions.In our hands hysteroscopic transcervical endomyometrial resection was a safe and effective treatment for menorrhagia in spite of the fact that amenorrhea was not always achieved. However, dysmenorrhea appeared in 11% of the women. The reason for this remains to be studied. Correct selection criteria is important to get optimal results and reduce the treatment failure.
