OBJECTIVE: To test non-hysteroscopic thermodestruction of the endometrium for safety and efficiency.
DESIGN: Prospective pilot study from February 1991 to July 1992.
SETTING: University Hospital Nijmegen.
PATIENTS AND METHOD: There were 68 patients aged 30-55 years with menorrhagia, who did not want children but wished to retain the uterus. There were two patients with a subserous myoma but with a normal uterine cavity. Patients with hypergonadotropism, a markedly enlarged uterus, abnormalities at cytological examination of the cervix, adnexal lesions, prolapse, intrauterine lesions and coagulation disorders were excluded. By way of preparation, danazol was administered for 4 weeks before the intervention (36 patients). Three patients with side effects were given lynestrenol. From January 1992, an LH-RH analogue was administered (29 patients) for 6 weeks prior to the intervention or in the patients with a subserous myoma for 12 weeks. Thermodestruction of the endometrium by means of radio waves was carried out according to a standard protocol under general or epidural spinal anaesthesia. The intracavitary temperature measured was 62-65 degrees C, mean duration of the treatment 20 minutes.
RESULTS: The patients were discharged 10-24 hours after the intervention. A non-disturbing watery discharge of 3-6 weeks' duration was reported. Normal activities were resumed after one week. Success (duration of follow-up 3-21 months) was defined as amenorrhoea (6 patients; 9%) or a markedly reduced menstruation or duration of menstruation (48 patients; 70%). Six patients (9%) reported no improvement and of eight patients (12%) with slight, unsatisfactory improvement three were treated again, with success (4%). During the trial period the method was further adjusted and perfected. There were no complications.
CONCLUSION: This preliminary experience shows that thermodestruction with radio waves is simple, safe and efficient.
