title: [The value of aimed biopsy in gastroscopy].
abstract: The introduction of the fiberscops with the possibility of the aimed biopsy has considerably improved the diagnostic evidence of gastroscopy, though there exists a whole series of technical problems in the histological ascertainment. Though all regions of the stomach are accessible to the biopsy forceps, the histological findings cannot always be ascertained clearly histologically. Of 105 carcinomata of the stomach and the oesophagus only 84 were verified clearly histologically. Of 101 ulcers appearing benign five proved to be malignant in histological respect. In 14 scars in two cases a carcinoma could be proved. Altogether from 27 polyps appearing benign bioptic material was taken, which in all cases confirmed the primary diagnosis, nevertheless at the operation one polyp proved to be malignant. In 105 cases endoscopically the diagnosis of a carcinoma was made, but in seven cases it was a benign ulcer clearly confirmed by the operation. It is reported on some own experiences concerning the improvement of the result of the aimed biopsy.
