  • Title: [The value of fiber gastroscopy and targeted gastrobiopsy in the diagnosis of stomach ulcers and tumors].
    Author: Kratzsch KH, Kubisch H, Fürstenau M, Winkelvoss H, Büttner W.
    Journal: Z Gesamte Inn Med; 1979 Oct 01; 34(19):265-7. PubMed ID: 543175.
    Abstract:
    In 2,000 patients the fiber-gastroscopic and bioptic findings were tested with the help of control examinations, results of operations and course observations. Here the fibergastroscopic diagnosis tumour was confirmed in 89.4%. 13 times a wrong diagnosis of tumour was made. Here different substrates were in question (ventricular ulcers, polypous hyperblastic mucous membrane and others). 11 carcinomas were gastroscopically not recognized as tumour. In 25 cases (20%) of the histological investigation of bioptically taken tissue did not result in a confirmation of the fiber-gastroscopic diagnosis of tumour. But 19 times of them the histology was falsely negative. The supplementation of the gastroscopy by biopsy resulted in a right diagnosis in 93.6%. By control examinations a further increase of the accuracy to 96.8% could be reached.
