Abstract
Three hundred and eighteen women with dysplasia, carcinoma in situ (CIS) and microinvasive carcinoma (MIC) were treated by CO2laser excision conization. One hundred and ninety eight patients (62.2%) were performed laser conization in the outpatient unit. Two hundred and fifteen patients (67.6%) after conization were followed up by cytology, colposcopy and histology. The recurrence rate after lyear was 3.4%. Postoperative bleeding rate was 1.7% in the inpatient laser conization group, while 10.6% in the outpatient group because of the lack of bed rest at home. Bed rest at home for a few days after conization must be insisted on in the outpatient group. Twenty one women after conization had given birth (after 24th week). Six of these cases (28.5%) were delivered preterm. Laser conization seemed to increase the risk of preterm delivery in subsequent pregnancies. Pregnant women with prior conization need careful antenatal care. These results suggested that CO2 laser conization was a highly effective method treating early cervical neoplasia, although we have to consider some complications.
