Kazuhiro Gono,Takashi Obi,Masahiro Yamaguchi,Nagaaki Ohyama,Hirohisa Machida,Yasushi Sano,Shigeaki Yoshida,Yasuo Hamamoto,Takao Endo +8 more
TL;DR: The results of clinical tests in colonoscopy and esophagoscopy indicated that NBI will be useful as a supporting method for observation of the endoscopic findings of early cancer.
Journal ArticleDOI
Narrow-band imaging in the diagnosis of colorectal mucosal lesions: a pilot study.
TL;DR: It is suggested that in the examination of colonic lesions the NBI system provides imaging features additional to those of both conventional endoscopy and chromoendoscopy.
Journal ArticleDOI

TL;DR: The Japan NBI Expert Team was constituted with the aim of establishing a universal NBI magnifying endoscopic classification for colorectal tumors (JNET classification) in 2011, and consensus was reached on this classification using the modified Delphi method in June 2014.
Journal ArticleDOI

TL;DR: A new illumination method for a medical endoscope: narrow band imaging (NBI), in which the spectral bandwidth of the filtered light is narrowed, which has been shown that NBI can enhance the capillary pattern and the crypt pattern on the mucosa.
Journal ArticleDOI
Small bowel injury by low-dose enteric-coated aspirin and treatment with misoprostol: a pilot study.
Toshio Watanabe,Satoshi Sugimori,Natsuhiko Kameda,Hirohisa Machida,Hirotoshi Okazaki,Tetsuya Tanigawa,Kenji Watanabe,Kazunari Tominaga,Yasuhiro Fujiwara,Nobuhide Oshitani,Kazuhide Higuchi,Tetsuo Arakawa +11 more
TL;DR: Low-dose enteric-coated aspirin frequently damages the small intestine, and misoprostol is effective in the treatment of aspirin-induced enteropathy.
