Diagnostic accuracy of endoscopic gastrobiopsy in carcinoma of the stomach. A histopathological review of 101 cases

摘要: 101 gastrobioptic series from 93 consecutive patients with a final diagnosis of carcinoma the stomach were reviewed. 20 false negative cases found. Of these, ten missed because erroneous histopathological interpretation, two too few sections, and eight was not represented in biopsies. The frequency negatives slightly larger ulcerating carcinomas than polypoid diffusely spreading carcinomas, mainly due to seven being by pathologist. There no correlation between histological type. rate significantly higher cases, where number biopsies taken below seven. misinterpretations actually positive four. Attempts increase yield should be based on only an evaluation biopsy technique, but also analysis method interpretation.
