Electrocoagulation diathermy.

With experience extending over an interval of 25 years, one single application of electrocoagulation diathermy has been substantiated as a most consistent and effective method of eradicating precancerous lesions of the cervix. Although there is a protocol for selection that must be adhered to, the vast majority of patients with CIN lesions are suitable for this method of ablative therapy. Ablation by electrocoagulation diathermy appears to have distinct advantages over other methods because of the following: 1. Very high cure rates (98%) with first-time treatment can be achieved, even for major dysplasia and/or carcinoma in situ. 2. Extensive and deep lesions can be effectively eradicated irrespective of the purported histological severity. 3. Electrodiathermy is capable of eradicating lesions extending into the endocervical canal, providing anatomical limits can be evaluated colposcopically. 4. The technique is simple and rapid. The versatility of the electrodes facilitates eradication of the lesion irrespective of the shape and contour of the cervix. 5. No expensive capital outlay nor costly maintenance of equipment is required. 6. There are no physical hazards for medical personnel. 7. It is cost-effective--the technique is readily adaptable as a true out-patient procedure on a 'walk in, walk out' basis. 8. It has a very low incidence of surgical morbidity and does not jeopardize physiological and reproductive function. 9. For practical purposes, the subsequent risk of development of invasive cancer of the cervix can be effectively eliminated.
