| 1 | Pathophysiological and clinical aspects of gastric hyperplastic polyps显示文摘Gastric polyps become a major clinical problem because of high prevalence and tendency to malignant transformation of some of them. The development of gastric hyperplastic polyps results from excessive proliferation of foveolar cells accompanied by their increased exfoliation, and they are macroscopically indistinguishable from other polyps with lower or higher malignant potential. Panendoscopy allows detection and differentiation of gastric polyps, usually after obtaining histopathological biopsy specimens. Unremoved gastric hyperplastic polyps may enlarge and sometimes spontaneously undergo a sequential progression to cancer. For this reason, gastric hyperplastic polyps larger than 5 mm in size should be removed in one piece. After excision of polyps with atypical focal lesion, endoscopic surveillance is suggested depending on histopathological diagnosis and possibility of confirming the completeness of endoscopic resection. Because of the risk of cancer development also in gastric mucosa outside the polyp, neighboring fragments of gastric mucosa should undergo microscopic investigations. This procedure allows for identification of patients who can benefit most from oncological endoscopic surveillance. If Helicobacter pylori(H. pylori) infection of the gastric mucosa is confirmed, treatment strategies should include eradication of bacteria, which may prevent progression of intestinal metaplasia. The efficacy of H. pylori eradication should be checked 3-6 mo later. | Adam Roman Markowski Agnieszka Markowska Katarzyna Guzinska-Ustymowicz | 2016 | World Journal of Gastroenterology2016，22，40： | 42 |
| 2 | 增生性胃息肉伴局灶癌显示文摘This paper reports a rare case of early adenocarcinoma within the gastric hyperplastic polyp,that was completely resected during an endoscopic procedure,and discusses current recommendations in such cases.Endoscopic resection of polyps with focal dysplasia or cancer is commonly indicated,as long as the procedure can be performed safely.After complete excision of a polyp with atypical focal lesion,endoscopic surveillance is suggested.The frequency of surveillance endoscopy should depend on the precise histopathological diagnosis and possibility of confirming the completeness of the endoscopic resection.If the completeness of the procedure is confirmed both macro-and microscopically,gastric resection does not have to be performed.A follow-up esophago-gastroduodenoscopy should be performed at 1 year and then at 3 years. | Adam Roman Markowski Katarzyna Guzinska-Ustymowicz | 2016 | Gastroenterology Report2016，4，2： | 1 |
