Advanced cancer in the esophagus is a serious and fatal disease that invades locally to deeper layers of the esophageal wall with significant risk of nodal metastasis and invasion of adjacent organs. One reliable method of avoiding this is to detect lesions at an early stage of esophageal cancer and then to resect them locally. A major advantage of(More)
Recent developments in image-enhancement technology have enabled clear visualization of the microvascular structure of the esophageal mucosa. In particular, intrapapillary capillary loops (IPCLs) are observed as brown loops on magnification endoscopy with narrow-band imaging (NBI). IPCLs demonstrate characteristic morphological changes according to the(More)
Progress in magnifying endoscopy has allowed endoscopic atypia to be evaluated on the basis of the presence or the absence of microvascular hyperplasia in a tumor. We focused our attention on intra-epithelial papillary capillary loops (IPCLs) and studied 20 cases of esophageal neoplasia (IPCL type III, 10 cases; IPCL type IV, 10 cases) and 99 vessels (IPCL(More)
NBI magnifying imaging with crystal violet (CV-NBI magnifying imaging) makes recognition of micro-vascular pattern and grandular structure in the gastric mucosa better. NBI image emphasizes micro-vascular structure in mucosal surface. Magnification endoscopy with crystal violet staining delineates surface grandular structure better than without it. Crystal(More)
