Diagnostic suction curettage was carried out in 82 women with genital bleeding, in 32 cases without anaesthesia and in 50 cases under general anaesthesia. The accuracy of the findings was checked by conventional curettage or hysterectomy in 75 cases. Dilatation of the endocervix was unnecessary in 81 women. Exact fractionation of the material obtained from the cervix and the body of the uterus was always possible, whereby the separation was just as good as with conventional curettage. The obtained aspirate enabled a histological diagnosis to be made in 80 cases. It was possible to prepare a cytological smear in 2 cases. The tolerance of patients to vacuum curettage carried out without anaesthesia was reasonably good. With Vabra-Duplex disposable set the physician has a device at his disposal which is particularly suitable for women still wishing to have a child and for patients in whom anaesthesia constitutes a risk factor. It appears to be suited for performance as an ambulant procedure.
