Abstract:
Objective To investigate the relationship between the pathology of gastric polyp tissues and the precancerous and malignant transformations of its background mucosa by endoscopic biopsy. Methods From 2003 to 2008,1825 patients were diagnosed with gastric polyps in our hospital by gastroscopy and pathological examination. We classified the lesions and then analyzed the relationship between pathological changes of gastric polyp tissues and the precancerous and malignant transformations of its background mucosa by endoscopic biopsy. Results In this study,the detection rate of gastric polyps was 4.3% (1825/42 003). The lesions included fundic gland polyps (FGP,62.5%,1141/1825),hyperplasia polyps (HPP,32.2%,587/1825),adenoma (0.8%,14/1825),inflammatory polyps (IP,1.7%,31/1825),and coincident polyps (two types of polyps were found in one case,2.8%,52/1825). The rates of intestinal metaplasia (IM,5.3%,31/587) and dysplasia (6.8%,40/587) in HPP tissue were higher than those in FGP tissues (0.2%,2/1141 and 0.4%,4/1141,P
