The aim of this study was to evaluate the short- and long-term outcomes for ESD using indication cri-teria. METHODS A total of 1,105 patients underwent ESD for EGC at six(More)
BACKGROUND/AIMS Interobserver variation by experience was documented for the diagnosis of esophagitis using the Los Angeles classification. The aim of this study was to evaluate whether interobserver agreement can be improved by higher levels of endoscopic experience in the diagnosis of erosive esophagitis. METHODS Endoscopic images of 51 patients with(More)
BACKGROUND/AIMS Mesenteric microvascular thrombosis has been implicated as a contributing factor to the pathogenesis of inflammatory bowel disease (IBD). The aim of the current study was to assess the possibility of subclinical atherosclerosis in patients with IBD by measuring their carotid intima-media thickness (c-IMT). METHODS Thirty-eight patients(More)
