| 1 | 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 |
| 2 | Acute pancreatitis successfully diagnosed by diffusion-weighted imaging: A case report显示文摘Diffusion-weighted imaging (DWI) is an established diagnostic method of acute stroke. The latest advances in magnetic resonance imaging (MRI) technology have greatly expanded the utility of DWI in the examination of various organs. Recent studies have revealed the usefulness of DWI for imaging of the liver, kidney, ovary, and breast. We report a patient with acute pancreatitis detected by DWI and discussed the efficacy of DWI in diagnosing acute pancreatitis. A 50-year old man presented with a primary complaint of abdominal pain. We performed both DWI and computed tomography (CT) for this patient. The signal intensity in a series of DWI was measured and the apparent diffusion coefficient (ADC) values were calculated to differentiate inflammation from normal tissue. Two experienced radiologists evaluated the grade of acute pancreatitis by comparing the CT findings. Initially, the pancreas and multiple ascites around the pancreas produced a bright signal and ADC values were reduced on DWI. As the inflammation decreased, the bright signal faded to an iso-signal and the ADC values returned to their normal level. There was no difference in the abilities of DWI and CT images to detect acute pancreatitis. However, our case indicates that DWI can evaluate the manifestations of acute pancreatitis using no enhancement material andhas the potential to replace CT as a primary diagnostic strategy for acute pancreatitis. | Satoshi Shinya Takamitsu Sasaki Yoshifumi Nakagawa Zhang Guiquing Fumio Yamamoto Yuichi Yamashita | 2008 | World Journal of Gastroenterology2008，14，35： | 16 |
| 3 | Efficacy of long-term rifaximin treatment for hepatic encephalopathy in the Japanese显示文摘BACKGROUND Hepatic encephalopathy(HE)is a complication of liver cirrhosis and can result in neuropsychological and neuromuscular dysfunctions in patients.Rifaximin,an antibiotic,has been reported to decrease the occurrence of overt HE and also improve cognitive function in studies from Europe and the United States of America.There is not enough evidence of the relationship between the long-term use of rifaximin and its clinical effects in the Japanese.AIM To determine the clinical effects of long-term rifaximin therapy in decompensated liver cirrhosis patients,with overt HE or hyperammonemia.METHODS In this single-center retrospective observational cohort study,we reviewed the data of 38 patients who had taken rifaximin at the dose of 1200 mg/d for more than 24 wk.The primary outcome measured was the efficacy of long-term rifaximin use,and secondary outcome measured was the safety of its long-term use as determined by its influence on portosystemic shunts as well as Escherichia coli-related infections.Moreover,we compared the prognosis between the rifaximin group and control cases,matched for hepatic elasticity assessed by magnetic resonance ela-stography,age,and Child-Pugh classification.RESULTS Of the 38 patients included in the study,12(31.6%)had overt HE,27(71.1%)had complications of esophageal varices,and 9(23.7%)had hepatocellular carcinoma(HCC).The control group was matched for age,Child-Pugh classification,liver stiffness,and presence of HCC.The median of serum ammonia level before treatment was 104μg/dL(59-297),and 2 wk after treatment,it significantly decreased to 85μg/dL(34-153)(P=0.002).A significantly low value of 80.5μg/dL(44-150)was maintained 24 wk after treatment.The long-term use of rifaximin did not cause a decline in liver function.Diarrhea occurred in 2 patients,who improved with the administration of probiotics,and there were no cases of aborted rifaximin therapy owing to adverse events.In patients with Child C,the survival was short,but there was no significant difference compared with that of the control group.CONCLUSION Rifaximin therapy improves overt HE.The long-term use of rifaximin in the Japanese is effective and safe. | Shinya Nishida Koichi Hamada Noriyuki Nishino Daizo Fukushima Ryota Koyanagi Yoshinori Horikawa Yoshiki Shiwa Satoshi Saitoh | 2019 | World Journal of Hepatology2019，11，6： | 3 |
| 4 | 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 |

| 10 | 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 |

| 19 | miR-23a promotes invasion of glioblastoma via HOXD10-regulated glial-mesenchymal transition显示文摘Glioblastoma is the most aggressive and invasive brain tumor and has a poor prognosis;elucidating the underlying molecular mechanisms is essential to select molecular targeted therapies.Here,we investigated the effect of microRNAs on the marked invasiveness of glioblastoma.U373 glioblastoma cells were infected with 140 different microRNAs from an OncomiR library,and the effects of the invasion-related microRNAs and targeted molecules were investigated after repeated Matrigel invasion assays.Screening of the OncomiR library identified miR-23a as a key regulator of glioblastoma invasion.In six glioblastoma cell lines,a positive correlation was detected between the expression levels of miR-23a and invasiveness.A luciferase reporter assay demonstrated that homeobox D10(HOXD10)was a miR-23a-target molecule,which was verified by high scores from both the PicTar and miRanda algorithms.Forced expression of miR-23a induced expression of invasion-related molecules,including uPAR,RhoA,and RhoC,and altered expression of glial-mesenchymal transition markers such as Snail,Slug,MMP2,MMP9,MMP14,and E-cadherin;however,these changes in expression levels were reversed by HOXD10 overexpression.Thus,miR-23a significantly promoted invasion of glioblastoma cells with polarized formation of focal adhesions,while exogenous HOXD10 overexpression reversed these phenomena.Here,we identify miR-23a-regulated HOXD10 as a pivotal regulator of invasion in glioblastoma,providing a novel mechanism for the aggressive invasiveness of this tumor and providing insight into potential therapeutic targets. | Kazuhiro Yachi Masumi Tsuda Shinji Kohsaka Lei Wang Yoshitaka Oda Satoshi Tanikawa Yusuke Ohba Shinya Tanaka | 2018 | Signal Transduction and Targeted Therapy2018，3，1： | 1 |
