[Morphologic evaluation of the potential of fluorescent analysis in the diagnosis of gastric diseases].

A method based on the secondary luminescence of malignant tumours facilitates a more precise taking of biopsies in ulcers and polyps undergoing malignant transformation in carcinoma developing against gastritis background as well as during emergency intraoperative diagnosis. 478 gastroscopies were performed in order to clarify the correlation between fluorescence and the presence of carcinoma in the luminescent biopsies. Biopsies were obtained from both fluorescent and non-fluorescent areas.
