[The practicability of the gravlee-jet-wash-technique--results of a laboratory (author's transl)].

The matter of examination were 171 jet-wash-proofs of 166 patients. In working up the material we aimed to get "sedimentsmears" and "specimens" by the aid of the cellbloc-technique. In the case of seventeen patients there was no material to be evaluated. Counting the 13 cases which were found necessary to be repeated because the quantity of material was too little, 17,5% of the cases finally could not be diagnosed. Using the histology of curettage, or the surgery preparations of 148 patients, we had something to compare with the results of the jet-wash-proofs. 11 out of 13 endometrial carcinomata (84,6%) were registered by the aid of the jet-wash-technique; this was contrasted with two false positive results out of 148 cases. The reasons of false positive and false negative results are being discussed. The efficiency of the jet-wash-technique depends on the prooftaking method, the way the material is worked up, and the kind of the dammage of the endometrium. The results show, that the use of a jet-washer is now, after a phase of learning, a diagnostical completion for the recognition of the endometrial carcinoma in high risk patients.
