title: [Treatment of cervical intraepithelial neoplasia using the CO2 laser].
abstract: The use of laser therapy in CIN, is a practical method that has revolutionized the treatment of a very common pathology, that is the cervical neoplasia in its early stages. 86 patients with different stages of cervical intraepithelial neoplasia, were studied. Patients in groups I (45 patients) y II (28 patients), were submitted to a vaporization crater of the whole transformation zone because of having the cervical canal free of lesion. In group III (13 patients), a cylinder of the cervix was done to perform histological study, whether the cervical canal was compromised or not. The cytology control results for group I were excellent; from (45 patients) who came to 3-month check-up 79.1% of the whole presented negative II. For group II (28 patients), in first pap smear two patients (7.1%) had CIN, the rest of smears were reported 66% negative II, and in the 30.6% negative I. For the group III 14.2% (5 patients) of the whole had abnormal results, the rest of the smears 73.5% of the results reported negative II. The incidence of failure for this procedure is similar to that of hysterectomy with the same therapeutic goal .
