| 1 | Novel image-enhanced endoscopy with i-scan technology显示文摘i-scan technology is the newly developed imageenhanced endoscopy technology from PENTAX,Japan.This consists of three types of algorithms:surface enhancement (SE),contrast enhancement (CE),and tone enhancement (TE).SE enhances light-dark contrast by obtaining luminance intensity data for each pixel and applying an algorithm that allows detailed observation of a mucosal surface structure.CE digitally adds blue color in relatively dark areas,by obtaining luminance intensity data for each pixel and applying an algorithm that allows detailed observation of subtle irregularities around the surface.Both enhancement functions work in real time without impairing the original color of the organ,therefore,SE and CE are suitable for screening endoscopy to detect gastrointestinal tumors at an early stage.TE dissects and analyzes the individual RGB components of a normal image.The algorithm then alters the color frequencies of each component and recombines the components to a single,new color image.This is designed to enhance minute mucosal structures and subtle changes in color.TE works in real time and consists of three modes such as TE-g for gastric tumors,TE-c for colonic tumors,and TE-e for esophageal tumors.TE is suitable mainly for detailed examination of the lesions that are detected in a screening endoscopy.i-scan technology leads us to easier detection,diagnosis and treatment of gastroi ntestinal diseases. | Shinya Kodashima Mitsuhiro Fujishiro | 2010 | World Journal of Gastroenterology2010，16，9： | 35 |
| 2 | Bleeding after endoscopic submucosal dissection: Risk factors and preventive methods显示文摘Endoscopic submucosal dissection(ESD) has become widely accepted as a standard method of treatment for superficial gastrointestinal neoplasms because it enables en block resection even for large lesions or fibrotic lesions with minimal invasiveness, and decreases the local recurrence rate. Moreover, specimens resected in an en block fashion enable accurate histological assessment. Taking these factors into consideration, ESD seems to be more advantageous than conventional endoscopic mucosal resection(EMR), but the associated risks of perioperative adverse events are higher than in EMR. Bleeding after ESD is the most frequent among these adverse events. Although post-ESD bleeding can be controlled by endoscopic hemostasis in most cases, it may lead to serious conditions including hemorrhagic shock. Even with preventive methods including administration of acid secretion inhibitors and preventive hemostasis, post-ESD bleeding cannot be completely prevented. In addition high-risk cases for post-ESD bleeding, which include cases with the use of antithrombotic agents or which require large resection, are increasing. Although there have been many reports about associated risk factors and methods of preventing post-ESD bleeding, many issues remain unsolved. Therefore, in this review, we have overviewed risk factors and methods of preventing post-ESD bleeding from previous studies. Endoscopists should have sufficient knowledge of these risk factors and preventive methods when performing ESD. | Yosuke Kataoka Yosuke Tsuji Yoshiki Sakaguchi Chihiro Minatsuki Itsuko Asada-Hirayama Keiko Niimi Satoshi Ono Shinya Kodashima Nobutake Yamamichi Mitsuhiro Fujishiro Kazuhiko Koike | 2016 | World Journal of Gastroenterology2016，22，26： | 16 |
| 3 | Curative ESD for intraepithelial esophageal carcinoma with leiomyoma mimicking submucosal invasive carcinoma显示文摘This case report presents a 65-year-old man who developed early esophageal cancer with leiomyoma treated by endoscopic submucosal dissection(ESD).There have been several reports of co-existing superficial esophageal cancer and leiomyoma treated by endoscopic mucosal resection.However,there is no previous report describing the co-existing lesion treated by ESD.In order to determine treatment strategies for esophageal cancer,accurate endoscopic evaluation of the cancerous depth is essential.In the present case,the combination of endoscopic ultrasonography and narrow-band imaging system with magnifying endoscopy was extremely useful to evaluate the superficial esophageal cancer with leiomyoma,which lead to the appropriate treatment,ESD. | Keiko Niimi Shinya Kodashima Satoshi Ono Osamu Goto Nobutake Yamamichi Mitsuhiro Fujishiro | 2009 | World Journal of Gastrointestinal Endoscopy2009，1，1： | 3 |

| 9 | Sessile serrated adenoma detection rate is correlated with adenoma detection rate显示文摘AIM To investigated the association between adenoma detection rate(ADR) and sessile serrated ADR(SSADR) and significant predictors for sessile serrated adenomas(SSA) detection.METHODS This study is a retrospective, single-center analysis. Total colonoscopies performed by the gastroenterologists at the University of Tokyo Hospital between January and December 2014 were retrospectively identified. Polyps were classified as low-grade or high-grade adenoma, cancer, SSA, or SSA with cytological dysplasia, and the prevalence of each type of polyp was investigated. Predictors of adenoma and SSA detection were examined using logistic generalized estimating equation models. The association between ADR and SSADR for each gastroenterologist was investigated by calculating a correlation coefficient weighted by the number of each gastroenterologist's examination.RESULTS A total of 3691 colonoscopies performed by 35 gastroenterologists were assessed. Overall, 978 (26.5%) low-and 84 (2.2%) high-grade adenomas, 81 (2.2%) cancers, 66 (1.8%) SSAs, and 2 (0.1%) SSAs with cytological dysplasia were detected. Overall ADR was 29.5%(men 33.2%, women 23.8%) and overall SSADR was 1.8%(men 1.7%, women 2.1%). In addition, 672 low-grade adenomas (68.8% of all the detected lowgrade adenomas), 58 (69.9%) high-grade adenomas, 29 (34.5%) cancers, 52 (78.8%) SSAs, and 2 (100%) SSAs with cytological dysplasia were found in the proximal colon. Adenoma detection was the only significant predictor of SSA detection (adjusted OR: 2.53, 95%CI: 1.53-4.20; P < 0.001). The correlation coefficient between ADR and SSADR weighted by the number of each gastroenterologist's examinations was 0.606(P < 0.001).CONCLUSION Our results demonstrated that ADR is correlated to SSADR. In addition, patients with adenomas had a higher prevalence of SSAs than those without adenomas. | Daisuke Ohki Yosuke Tsuji Tomohiro Shinozaki Yoshiki Sakaguchi Chihiro Minatsuki Hiroto Kinoshita Keiko Niimi Satoshi Ono Yoku Hayakawa Shuntaro Yoshida Atsuo Yamada Shinya Kodashima Nobutake Yamamichi Yoshihiro Hirata Tetsuo Ushiku Mitsuhiro Fujishiro Masashi Fukayama Kazuhiko Koike | 2018 | World Journal of Gastrointestinal Oncology2018，10，3： | 2 |
