METHODS BB staining method and steps:Othe examinee was injected IM 20 mg of Anisodamini Hydromidum;②he took a cup of BB solution;③after 40-60 min he was examined with the endoscope.All of the examinee were also examined with the rou- tine endoscope. RESULTS Sixteen of 54 patients were demonstrated to suffer from early gastric cancer,the detecting rate of early cancer being 29.4%.Among these,15 cases were discovered by BB endoscopy,and only 5 cases by the routine endoscopy.The for- mer is more sensitive in discovering early gastric cancer than the latter(P<0.01)o In addition,the BB endoscopy increases the positive rate of biopsy from 70.4%(38/54)to 94.4%(51. 54),which is clearly supperior in the diagnosis of gastric can- cer to that by routine endoscopy(P<0.01). CONCLUSIONS The BB chromo-endoscopy is more useful in following up the gastric precancerous lesion than the routine endoscopy.展开更多

These voids are not lined with epithelia. There are few reported cases about colon, duodenum and skin. Because there is only one case report about pseudolipomatosis in the stomach, we reevaluated 909 endoscopic biopsies taken from gastric corpus to check the presence of pseudolipomatosis. We determined pseudolipomatosis foci in 3 percent (n=27) of biopsies. In two cases there were pseudolipomatosis foci in endoscopic biopsies having otherwise normal histologic findings, while there were pseudolipomatosis foci in endoscopic biopsies of 25 patients with gastritis. H pylori was found in 85 % of biopsies having pseudolipomatosis foci. In this study, we presented some histopathologic characteristics of pseudolipomatosis seen in gastric mucosa.展开更多
