自身免疫性萎缩性胃炎或萎缩性胃体胃炎(ACG)与胃腺癌和类癌以及食管、胰腺和结肠等消化器官恶性肿瘤的发生有关。本研究对比观察口服与内镜下十二指肠灌注聚乙二醇(PEG)600(分子量414～766)后吸收情况,探讨ACG患者胃粘膜通透性的变化。
Autoimmune atrophic gastritis or atrophic gastritis (ACG) is associated with the development of gastric adenocarcinoma and carcinoid as well as malignant tumors of digestive organs such as esophagus, pancreas and colon. This study compared the oral and endoscopic duodenal perfusion of polyethylene glycol (PEG) 600 (molecular weight 414 ~ 766) after the absorption of gastric mucosal permeability in patients with ACG changes.
