Laser vaporization of the cervix for the management of cervical intraepithelial neoplasia

The incidence of cervical-uterine cancer is very high in many countries of Latin America and the rales of mortality, statistically have shown its social importance. This malignancy emerges very often as a progressive disease beginning from intrauterine changes to invasive processes. Therefore surgeon’s aim is to detect and treat these lesions in their very early phase when the cure of 100% is still possible. The author studied prospectively 21 patients with intraepithelial cervical neoplasia. The patients were screened by citology and had their diagnosis confirmed by histopathological examinations after colposcopic biopsy. The therapy employed was the vaporization with CO2 laser. The criteria for patients selection were: 1) The safe evidence of the changed area after colposcopy eliminating the possibility of a invasive lesion. 2) The inicial cervical neoplasia should be limited to the ectocervix without extension forward the cervical canal. 3) The correspondence among citology, colposcopy and histology. The use of the CO2 laser with microscope has made the procedure more precise which is applied in outpatient basis. No anesthetic has been needed and the operative time was 15 minutes on average. The final healing was completed after the third week and no special postoperative care has been necessary. Two cases had slight vaginal bleeding on 5th and 10th postoperative days but stopped after vaginal tamponing for 24 hours. The colposcopies and operations were done by the senior author. One patient had a second procedure on the 5th month of follow up. Another had at the 26th month of follow up a recurrency and is scheduled to accomplish the treatment. The other twenty are under close control with no recurrencies. The results showed a 95% rate of cure according to the world literature. Concluding the employment of the CO2 laser or the treatment of the intraepethelial cervical neoplasia has been suggested as an useful alterna tive to be: fast, painless, low costing and with low rates of complications. Late effects to fertility and cervical competence have not been observed. Additionally the minor thermal damage and the possibility of new procedures could be pointed as advantages of a method that carries a high incidence of cure.
