[Conization of the uterine cervix. A study of 900 cases].

In the years 1968 till 1982, 900 conisations of uterine cervix were performed, 90% of which were diagnostic interventions. During the follow-up period, the mean age of the patients with carcinoma in situ decreased 4 years, the mean age from patients with microcarcinoma 3.2 years. In 64% the conisation was carried out due to a positive or suspekt smear. Conisations, performed during pregnancy, were not associated with any additional complications for mother or child. Taking a big conus resulted more often in a total extirpation of the neoplastic changes, without increasing the complication rate. The average hospital stay was 8.7 days. It was only prolonged in patients with secondary hemorrhage. 33% of all neoplastic changes were extirpated totally. In 85% of the women who had follow-up only after incomplete extirpation of the neoplasia by conisation, there was no recurrence. The rest did show the neoplasia again, often in a more serious way. The overall complication-rate was 7.4%.
