Treatment of premalignant lesions of the uterine cervix by means of moderate heat thermosurgery using the SEMM coagulator.

71 patients suffering from premalignant lesions of the uterine cervix and who were treated by the SEMM coagulator, is presented. The results are good, and at least equal to cryosurgery. The time of follow-up has been more than 2 years for 57 of the patients and more than 3 years for 39. Only in two cases has there been persistence or recurrence of suspicious cytology requiring new treatment, in one of them by conization and in the other by cryosurgery. One patient was hysterectomized for other reasons 2 years post-treatment, but no sign of persisting malignant or premalignant changes were found in the specimen. The method is judged to be a valuable alternative to conization and cryosurgery.
