Background and Aim: Presently, the differential diagnosis of gastric adenoma and well‐differentiated adenocarcinoma by endoscopy is very difficult. We carried out magnifying endoscopy with narrow band imaging (NBI) in lesions that required discrimination between gastric adenoma and well‐differentiated adenocarcinoma, and prospectively evaluated whether the tumor typing that we propose is useful for...
Background Endoscopic resection was recommended as treatment for mucosal epithelium or lamina propria mucosae lesions not exceeding two-thirds of the circumference. The aim of this study was to verify the outcomes of endoscopic resection and surgery for early and superficial carcinoma of the esophagus. Methods Endoscopic submucosal dissection (ESD) was performed for 56 cases of early and superficial...
Tissue factor (TF) is an initiation cofactor of the extrinsic pathway of coagulation. Although the overexpression of TF antigen and mRNA have been previously demonstrated in atherosclerotic lesions using both immunohistochemical and in situ hybridization techniques, it still remains unclear as to whether TF activity is overexpressed in atherosclerotic plaque in vivo. In thoracic aortas obtained...
