[Studies on pregnancy after CO2 laser conization for cervical intraepithelial neoplasia].
One hundred and sixteen patients with cervical intraepithelial neoplasia were treated by CO2 laser excisional conization, from 1985 to 1987. All operations in this series were performed in the outpatient unit. 1) In this series, 83.6% (97 out of 116) were patients with CIN and 44.0% (51 out of 116) were patients under the age 39 who can be pregnant. 2) There was no remaining in the 16 materials out of 44 obtained by hysterectomy due to cervical dysplasia and carcinoma in situ (CIS). 3) In our series, 10.3% (6 out of 58) of the women with dysplasia or CIS (surgical margin negative) required two treatments respectively to eradicate their disease from 9 months to 16 months after laser conization. 4) None of 72 women developed postoperative cervical stenosis and cervical infection. 5) Much of the epithelial cover, although originating from columnar cells, became squamous epithelium by 28 days. 6) There were 5 pregnancies in 72 patients, from 5 months to 13 after laser conization. From our studies, a CO2 laser conization for treating CIN preserved the architecture of the cervix, permitting adequate colposcopic and cytological follow-up, and preserved cervical function, so that fertility is not affected and so that there is no interference with pregnancy.
