[Comparison of YAG and CO2 laser excisional conization for the treatment of uterine cervical neoplasia].
Thirty-nine patients with cervical neoplasia who were treated by CO2 laser excisional conization were compared with a group of 37 patients whose diagnosis and age were similar were treated by YAG laser excisional conization. Every operation in our series was performed on an outpatient basis. The differences between two groups were statistically significant: The CO2 laser group revealed the advantages in the healing periods from treatment to the end of epithelization (p less than 0.01: T test) and irradiation time (p less than 0.001). There was no difference in the blood loss during the operation. Both initial cure rates were 100% during the follow-up period of 21 to 65 months. During and post operations, more patients required additional measures such as sutures for uncontrollable bleeding in the CO2 laser group. In conclusion, both methods are felt to be good diagnostic and also therapeutic procedures for cervical neoplasia on an outpatient basis.
