Journal ArticleDOI
Linked color imaging (LCI), a novel image-enhanced endoscopy technology, emphasizes the color of early gastric cancer
Hiromitsu Kanzaki,Ryuta Takenaka,Yoshiro Kawahara,Daisuke Kawai,Yuka Obayashi,Yuki Baba,Hiroyuki Sakae,Tatsuhiro Gotoda,Yoshiyasu Kono,Ko Miura,Masaya Iwamuro,Seiji Kawano,Takehiro Tanaka,Hiroyuki Okada +13 more
TL;DR: LCI had a larger ΔE than WLI, which may allow easy recognition and early detection of gastric cancer, even for inexperienced endoscopists.
Journal ArticleDOI
Increase in antibiotic resistant Helicobacter pylori in a University Hospital in Japan.
Chihiro Kageyama,Mayu Sato,Hiroyuki Sakae,Yuka Obayashi,Yoshiro Kawahara,Takehiko Mima,Osamu Matsushita,Kenji Yokota,Motowo Mizuno,Hiroyuki Okada +9 more
TL;DR: Genetic analysis for resistant strains is not clinically effective in cases of amoxicillin resistance, and MIC measurement should be considered via several methods for effective eradication therapy.
Journal ArticleDOI
Postoperative bleeding risk after gastric endoscopic submucosal dissection during antithrombotic drug therapy.
Yoshiyasu Kono,Yuka Obayashi,Yuki Baba,Hiroyuki Sakae,Tatsuhiro Gotoda,Ko Miura,Hiromitsu Kanzaki,Masaya Iwamuro,Seiji Kawano,Yoshiro Kawahara,Takehiro Tanaka,Hiroyuki Okada +11 more
TL;DR: The safety of gastric endoscopic submucosal dissection (ESD) in the antithrombotic drug users remains controversial.
Journal ArticleDOI
Evaluation of the Usefulness and Convenience of the Kyoto Classification of Gastritis in the Endoscopic Diagnosis of the Helicobacter Pylori Infection Status
Hiroyuki Sakae,Masaya Iwamuro,Yuki Okamoto,Yuka Obayashi,Yuki Baba,Kenta Hamada,Tatsuhiro Gotoda,Makoto Abe,Yoshiyasu Kono,Hiromitsu Kanzaki,Seiji Kawano,Yoshiro Kawahara,Takehiro Tanaka,Hiroyuki Yanai,Hiroyuki Okada +14 more
TL;DR: A brief mini-lecture on the Kyoto Classification of Gastritis improved the accuracy in the endoscopic diagnosis of gastritis, indicating that understanding this classification is useful for the prompt diagnosis of H. pylori infection during esophagogastroduodenoscopy.
Journal ArticleDOI
Risk Factors for Gastric Cancer after the Eradication of Helicobacter pylori Evaluated Based on the Background Gastric Mucosa: A Propensity Score-matched Case-control Study
Yuka Obayashi,Seiji Kawano,Hiroyuki Sakae,Makoto Abe,Yoshiyasu Kono,Hiromitsu Kanzaki,Masaya Iwamuro,Yoshiro Kawahara,Takehiro Tanaka,Hiroyuki Yanai,Hiroyuki Okada +10 more
TL;DR: A continuous high level of inflammation of the background gastric mucosa may be a risk factor for gastric cancer onset after H. pylori eradication, according to a multivariate analysis.
