 Gastric endoscopy is considered to be the standard method for detecting gastric cancer, but we are not satisfied with its detection accuracy. A total of 13,717 gastroscopic examinations with gastric biopsy were carried out at our institution between 1997 and 2000. In 427 examinations endoscopic diagnoses differed from histological diagnoses of biopsy specimens. Regarding endoscopic diagnosis, the false negative rate, positive predictive value and efficiency were 36.4%, 48.6% and 96.8%, respectively. Among 270 false positive cases, depressed lesions, minimal lesions, protruded lesions and diffuse lesions were 128,105, 36 and 1, respectively. We consider hyperplastic polyps, gastritis cystica polyposa, submucosal heterotopia of gastric glands, inflammatory fibroid polyps, verrucous gastritis, pseudosarcomatous granulation of the esophagogastric junction and fundic gland polyps to be important non-neoplastic lesions resembling protruded-type gastric cancers. Endoscopists should understand the macroscopic features of these lesions in order to distinguish them from protruded-type gastric cancers.
