Endoscopic exploration of the small bowel after pelvic radiation has limitations related to strong abdominal adhesion. It is often difficult to demonstrate the findings of radiation enteritis endoscopically, even with video capsule endoscopy (VCE) or double-balloon enteroscopy (DBE). We present our experience with three cases of radiation enteritis that(More)
Endoscopic treatment for superficial non-ampullary duodenal tumors is technically difficult and challenging due to the anatomical characteristics of the duodenum. It is frequently complicated by procedural accidents, such as perforation. Surgical repair has long been the standard treatment for acute iatrogenic gastrointestinal perforation. However,(More)
Double-balloon endoscopy (DBE) has enabled precise diagnosis and endoscopic intervention deep within the small bowel. In this study, we determine the factor related to the risk of endoscopic and clinical recurrences in the diagnosis of postoperative lesions including anastomosis for the patients with Crohn's disease. Forty-eight patients (40 men and 8(More)
Background. Although the usefulness of capsule endoscopy (CE) and double-balloon endoscopy (DBE) for the evaluation of Crohn's disease (CD) is established, their capabilities in the differential diagnosis of small bowel stenosis have not been sufficiently addressed. The present study therefore aimed to retrospectively determine the types of patients for(More)
BACKGROUND/AIMS To confirm the feasibility of using newly developed endoscopic ultrasound (EUS) with Zone sonography™ technology (ZST; Fujifilm Corp.). METHODS Seventy-five patients with pancreatic disorders were enrolled: 45 with intraductal papillary mucinous neoplasm; 15 with ductal carcinoma; five with neuroendocrine tumors; three with serous cystic(More)
BACKGROUND AND STUDY AIMS Endoscopic tissue acquisition techniques using needle-knife and biopsy forceps allow abundant tissue acquisition from upper gastrointestinal subepithelial lesions; however, these techniques cannot capture real-time intratumor information. The aim of this study was to evaluate the feasibility of endoscopic ultrasound-guided forceps(More)
UNLABELLED Double-balloon endoscopy (DBE) is useful for the diagnosis and treatment of small bowel diseases. Although fluoroscopy is used to confirm the position of endoscope at DBE, the endoscopist does not have the knowledge with regard to the radiation exposure dose. In this study, we evaluated the absorbed dose during DBE in patients with suspected or(More)
The patient was a 72 year old man who had been given non-steroidal anti-inflammatory drug (NSAID) for two years. He repeatedly developed small intestinal ileus; therefore, he underwent several imaging examinations, but the cause was not identified. He subsequently underwent a double-balloon endoscopy (DBE). The membranous stenoses were detected in the(More)
Liposomes (LIPO), which are concentric lipid layers alternating with aqueous compartments, have been suggested as a potential carrier for various drugs. In the previous studies, we have demonstrated that anticonvulsant drugs such as valproic acid, phenytoin, and DN-1417 (an analog of thyrotropin-releasing hormone) entrapped into LIPO exert more prominent(More)
