摘要: We herein report a case of gastric hyperplastic polyps after argon plasma coagulation (APC) for antral vascular ectasia (GAVE) in the antrum 65-year-old man with liver cirrhosis and hypergastrinemia induced by long-term proton pump inhibitor (PPI) use. Two years APC therapy, endoscopy demonstrated multiple angle. A polyp biopsy indicated foveolar epithelium hyperplasia, which was diagnosed as polyps. One year switching to an H2 blocker antagonist, revealed that GAVE had disappeared, normal gastrin levels suggesting PPI-induced caused disappeared discontinuing PPIs.
