BACKGROUND Crohn's disease (CD) strictures of the small intestine are a feared complication and difficult to treat because of difficulty gaining access to the stricture site. The development of double-balloon endoscopy (DBE) enabled access to the entire small intestine with interventional capabilities. The aim of this study was to assess the long-term… (More)
Barrett's adenocarcinoma may occur in multiple sites, and recurrence and metachronous lesions are the major problems with endoscopic resection. Therefore, early detection of such lesions is ideal to achieve complete resection and obtain improved survival rates with minimally invasive treatment. Laser imaging systems allow multiple modalities of endoscopic… (More)
Conventional endoscopy can miss flat early gastric cancers (0-IIb) because they may not be visible. We treated a patient with synchronous flat early gastric cancers missed by conventional white-light endoscopy (WLE). A 74-year-old Japanese male was referred for endoscopic submucosal dissection (ESD) of a depressed-type early gastric cancer (0-IIc) on the… (More)
High mobility and c-axis orientated ZnO thin films were deposited on glass substrates using RF sputtering method at room temperature. Structural properties of ZnO thin films were investigated by X-ray diffraction (XRD). Surface morphology and roughness were studied with scanning electron microscopy (SEM) and atomic force microscopy (AFM). Electrical… (More)
BACKGROUND AND AIMS The feasibility of endoscopic submucosal dissection (ESD) for large superficial colorectal tumors is undefined. The aim of this study was to assess the outcomes for patients undergoing ESD of superficial colorectal tumors larger than 50 mm. METHODS A total of 472 patients who underwent ESD for superficial colorectal tumors from 2010 to… (More)
