[On the optimal clarification of suspicous findings on the cervix uteri (author's transl)].

In the period 1972--1975 432 conizations were performed. 76,6% of all patients were dismissed healed after conization without necessity of hysterectomy; the duration of stay in hospital after operation was in uncomplicated cases 7,9 days, in complicated cases 9,9 days. In 13,9% complications were registered, mainly bleedings (10,9%). In more than half of the cases with not totaly removed carcinoma in situ the uterus showed rests of the malignant lesion. That indicates that in such situations a hysterectomy should be done in every case. If there was a suspicion of invasive carcinoma an excochleation was performed instead of cone biopsy. The high rate of false negative results in such cases confirms that the conization at the moment seems to be the method of choice in clarification of positive cytologic or colposcopic findings.
