Journal ArticleDOI
Long-Term Outcome and Metastatic Risk After Endoscopic Resection of Superficial Esophageal Squamous Cell Carcinoma
Takeshi Yamashina,Ryu Ishihara,Kengo Nagai,Noriko Matsuura,Fumi Matsui,Takashi Ito,Mototsugu Fujii,Sachiko Yamamoto,Noboru Hanaoka,Yoji Takeuchi,Koji Higashino,Noriya Uedo,Hiroyasu Iishi +12 more
TL;DR: The long-term risk of metastasis after ER was mainly associated with the depth of invasion, and this risk should be taken into account when considering the indications for ER.
Journal ArticleDOI
Intralesional steroid injection to prevent stricture after endoscopic submucosal dissection for esophageal cancer: a controlled prospective study.
Noboru Hanaoka,Ryu Ishihara,Yoji Takeuchi,Noriya Uedo,Koji Higashino,Takashi Ohta,Hiromitsu Kanzaki,Masao Hanafusa,Kengo Nagai,Fumi Matsui,Hiroyasu Iishi,Masaharu Tatsuta,Yuri Ito +12 more
TL;DR: A single session of intralesional steroid injections showed promising results for the prevention of stricture after ESD for esophageal cancer.
Journal ArticleDOI
Effect of a proton pump inhibitor or an H2-receptor antagonist on prevention of bleeding from ulcer after endoscopic submucosal dissection of early gastric cancer: a prospective randomized controlled trial.
Noriya Uedo,Yoji Takeuchi,Takuya Yamada,Ryu Ishihara,Hideharu Ogiyama,Sachiko Yamamoto,Motohiko Kato,Koichi Tatsumi,Eriko Masuda,Chie Tamai,Shunsuke Yamamoto,Koji Higashino,Hiroyasu Iishi,Masaharu Tatsuta +13 more
TL;DR: PPI therapy more effectively prevented delayed bleeding from the ulcer created after ESD than did H2RA treatment.
Journal ArticleDOI
Hepatocellular carcinoma arising from non-cirrhotic nonalcoholic steatohepatitis.
Natsuko Kawada,Kazuho Imanaka,Tsukasa Kawaguchi,Chie Tamai,Ryu Ishihara,Takashi Matsunaga,Kunihito Gotoh,Terumasa Yamada,Yasuhiko Tomita +8 more
TL;DR: This study indicates HCC might arise frequently from non-cirrhotic NASH and warrant regular screening for HCC, while further studies are needed to confirm this observation.
Journal ArticleDOI
Prediction of the invasion depth of superficial squamous cell carcinoma based on microvessel morphology: magnifying endoscopic classification of the Japan Esophageal Society
Tsuneo Oyama,Haruhiro Inoue,Miwako Arima,Kumiko Momma,Tai Omori,Ryu Ishihara,Dai Hirasawa,Manabu Takeuchi,Akihisa Tomori,Kenichi Goda +9 more
TL;DR: It is proposed that the newly developed JES magnifying endoscopic classification is useful in estimating the invasion depth of superficial esophageal squamous cell carcinoma.
