1为表面的胃肠的瘤的移动的内视镜的 submucosal 解剖: 技术评论显示文摘 Endoscopic submucosal dissection (ESD) is now the most common endoscopic treatment in Japan for intramucosal gastrointestinal neoplasms (non-metastatic). ESD is an invasive endoscopic surgical procedure, requiring extensive knowledge, skill, and specialized equipment. ESD starts with evaluation of the lesion, as accurate assessment of the depth and margin of the lesion is essential. The devices and strategies used in ESD vary, depending on the nature of the lesion. Prior to the procedure, the operator must be knowledgeable about the treatment strategy(ies), the device(s) to use, the electrocautery machine settings, the substances to inject, and other aspects. In addition, the operator must be able to manage complications, should they arise, including immediate recognition of the complication(s) and its treatment. Finally, in case the ESD treatment is not successful, the operator should be prepared to apply alternative treatments. Thus, adequate knowledge and training are essential to successfully perform ESD.Noriaki Matsui Kazuya Akahoshi Kazuhiko Nakamura Eikichi Ihara Hiroto Kita 2012World Journal of Gastrointestinal Endoscopy2012,4,4:34

3Removal of diminutive colorectal polyps: A prospective randomized clinical trial between cold snare polypectomy and hot forceps biopsy显示文摘AIM To compare the efficacy and safety of cold snare polypectomy(CSP) and hot forceps biopsy(HFB) for diminutive colorectal polyps.METHODS This prospective, randomized single-center clinical trial included consecutive patients ≥ 20 years of age with diminutive colorectal polyps 3-5 mm from December 2014 to October 2015. The primary outcome measures were en-bloc resection(endoscopic evaluation) and complete resection rates(pathological evaluation). The secondary outcome measures were the immediate bleeding or immediate perforation rate after polypectomy, delayed bleeding or delayed perforation rate after polypectomy, use of clipping for bleeding or perforation, and polyp retrieval rate. Prophylactic clipping after polyp removal wasn't routinely performed.RESULTS Two hundred eight patients were randomized into the CSP(102), HFB(106) and 283 polyps were evaluated(CSP: 148, HFB: 135). The en-bloc resection rate was significantly higher with CSP than with HFB [99.3%(147/148) vs 80.0%(108/135), P < 0.0001]. The complete resection rate was significantly higher with CSP than with HFB [80.4%(119/148) vs 47.4%(64/135), P < 0.0001]. The immediate bleeding rate was similar between the groups [8.6%(13/148) vs 8.1%(11/135), P = 1.000], and endoscopic hemostasis with hemoclips was successful in all cases. No cases of perforation or delayed bleeding occurred. The rate of severe tissue injury to the pathological specimen was higher HFB than CSP [52.6%(71/135) vs 1.3%(2/148), P < 0.0001]. Polyp retrieval failure was encountered CSP(7), HFB(2).CONCLUSION CSP is more effective than HFB for resecting diminutive polyps. Further long-term follow-up study is required.Yoriaki Komeda Hiroshi Kashida Toshiharu Sakurai George Tribonias Kazuki Okamoto Masashi Kono Mitsunari Yamada Teppei Adachi Hiromasa Mine Tomoyuki Nagai Yutaka Asakuma Satoru Hagiwara Shigenaga Matsui Tomohiro Watanabe Masayuki Kitano Takaaki Chikugo Yasutaka Chiba Masatoshi Kudo 2017World Journal of Gastroenterology2017,23,2:20
4Therapeutic efficacy of the Qing Dai in patients with intractable ulcerative colitis显示文摘Ulcerative colitis (UC) is a chronic inflammatory bowel disease that may become intractable when treated with conventional medications such as aminosalicylates, corticosteroids, and azathioprine. The herbal medicine Qing Dai has traditionally been used in Chinese medicine to treat UC patients, but there is a lack of published data on the efficacy of Qing Dai in UC treatment. We report several cases of patients with intractable UC who take Qing Dai in a retrospective observational study. Furthermore, we explore the mechanisms of action of Qing Dai. Nine patients with active UC who received conventional medications but wished to receive Qing Dai as an alternative medication were included in our analysis. The UC severity level was determined based on the clinical activity index (CAI). Additionally, 5 of the 9 patients were endoscopically evaluated according to the Matts grading system. Each patient received 2 g/d of Qing Dai orally and continued taking other medications for UC as prescribed. Electron spin resonance was applied to explore the mechanisms of action of Qing Dai. After 4 mo of treatment with Qing Dai, the CAI score decreased from 8.3 ± 2.4 to 2.4 ± 3.4 (mean ± SD; P < 0.001). Similarly, the endoscopic Matts grade decreased from 3.4 ± 0.5 to 2.2 ± 0.8 (P = 0.02). Six of 7 patients who were on prednisolone upon enrollment in the study were able to discontinue this corticosteroid. Electron spin resonance revealed that Qing Dai possesses strong hydroxyl radical scavenging activity. Qing Dai showed significant clinical and endoscopic efficacy in patients who failed to respond to conventional medications. Scavenging of hydroxyl radicals appears to be a potential mechanism through which Qing Dai acts, but the significance of the scavenging ability of Qing Dai with respect to the anti-inflammatory effect in UC patients warrants further investigation.Hideo Suzuki Tsuyoshi Kaneko Yuji Mizokami Toshiaki Narasaka Shinji Endo Hirofumi Matsui Akinori Yanaka Aki Hirayama Ichinosuke Hyodo 2013World Journal of Gastroenterology2013,19,17:19

8Efficacy of treatment with rebamipide for endoscopic submucosal dissection-induced ulcers显示文摘AIM:To prospectively compare the healing rates of endoscopic submucosal dissection(ESD)-induced ulcers treated with either a proton-pump inhibitor(PPI)or rebamipide.METHODS:We examined 90 patients with early gastric cancer who had undergone ESD.All patients were administered an intravenous infusion of the PPI lansoprazole(20 mg)every 12 h for 2 d,followed by oral administration of lansoprazole(30 mg/d,5 d).After7-d treatment,the patients were randomly assigned to 2 groups and received either lansoprazole(30 mg/d orally,n=45;PPI group)or rebamipide(300 mg orally,three times a day;n=45;rebamipide group).At 4and 8 wk after ESD,the ulcer outcomes in the 2 groups were compared.RESULTS:No significant differences were noted in patient age,underlying disease,tumor location,Helicobacter pylori infection rate,or ESD-induced ulcersize between the 2 groups.At both 4 and 8 wk,the healing rates of ESD-induced ulcers were similar in the PPI-treated and the rebamipide-treated patients(4 wk:PPI,27.2%;rebamipide,33.3%;P=0.5341;8 wk:PPI,90.9%;rebamipide,93.3%;P=0.6710).At 8 wk,the rates of granulation lesions following ulcer healing were significantly higher in the PPI-treated group(13.6%)than in the rebamipide-treated group(0.0%;P=0.0103).Ulcer-related symptoms were similar in the2 treatment groups at 8 wk.The medication cost of 8-wk treatment with the PPI was 10945 yen vs 4889 yen for rebamipide.No ulcer bleeding or complications due to the drugs were observed in either treatment group.CONCLUSION:The healing rate of ESD-induced ulcers was similar with rebamipide or PPI treatment;however,rebamipide treatment is more cost-effective and prevents granulation lesions following ulcer healing.Masaki Takayama Shigenaga Matsui Masanori Kawasaki Yutaka Asakuma Toshiharu Sakurai Hiroshi Kashida Masatoshi Kudo 2013World Journal of Gastroenterology2013,19,34:15
9Enhancement patterns of pancreatic adenocarcinoma on conventional dynamic multi-detector row CT:Correlation with angiogenesis and fibrosis显示文摘AIM:To evaluate retrospectively the correlation between enhancement patterns on dynamic computed tomography (CT) and angiogenesis and fibrosis in pancreatic adenocarcinoma.METHODS: Twenty-three patients with pancreatic adenocarcinoma underwent dynamic CT and tumor resection. In addition to the absolute and relative enhanced value that was calculated by subtracting the attenuation value on pre-contrast from those on contrast-enhanced CT in each phase, we defined one parameter, 'tumor-aorta enhancement ratio', which was calculated by dividing enhancement of pancreatic cancer by enhancement of abdominal aorta in each phase. These enhancement patterns were correlated with the level of vascular endothelial growth factor (VEGF), microvessel density (MVD), and extent of fibrosis.RESULTS: The absolute enhanced value in the arterial phase correlated with the level of VEGF and MVD (P=0.047, P=0.001). The relative enhanced value in arterial phase and tumor-aorta enhancement ratio (arterial) correlated with MVD (P=0.003, P=0.022). Tumor-aorta enhancement ratio (arterial) correlated negatively with the extent of fibrosis (P=0.004). The tumors with greater MVD and higher expression of VEGF tended to show high enhancement in the arterial dominant phase. On the other hand, the tumors with a larger amount of fibrosis showed a negative correlation with the grade of enhancement during the arterial phase.CONCLUSION: Enhancement patterns on dynamic CT correlated with angiogenesis and may be modified by the extent of fibrosis.Yuki Hattori Toshifumi Gabata Osamu Matsui Kentaro Mochizuki Hirohisa Kitagawa Masato Kayahara Tetsuo Ohta Yasuni Nakanuma 2009World Journal of Gastroenterology2009,15,25:15
10Feasibility of cold snare polypectomy in Japan: A pilot study显示文摘AIM: To investigate the feasibility of cold snare polypectomy(CSP) in Japan.METHODS: The outcomes of 234 non-pedunculated polyps smaller than 10 mm in 61 patients who underwent CSP in a Japanese referral center were retrospectively analyzed. The cold snare polypectomies were performed by nine endoscopists with no prior experience in CSP using an electrosurgical snare without electrocautery.RESULTS: CSPs were completed for 232 of the 234 polyps. Two(0.9%) polyps could not be removed without electrocautery. Immediate postpolypectomy bleeding requiring endoscopic hemostasis occurred in eight lesions(3.4%; 95%CI: 1.1%-5.8%), but all were easily managed. The incidence of immediate bleeding after CSP for small polyps(6-9 mm) was significantly higher than that of diminutive polyps(≤ 5 mm; 15% vs 1%, respectively). Three(5%) patients complained of minor bleeding after the procedure but required no intervention. The incidence of delayed bleeding requiringendoscopic intervention was 0.0%(95%CI: 0.0%-1.7%). In total, 12% of the resected lesions could not be retrieved for pathological examination. Tumor involvement in the lateral margin could not be histologically assessed in 70(40%) lesions.CONCLUSION: CSP is feasible in Japan. However, immediate bleeding, retrieval failure and uncertain assessment of the lateral tumor margin should not be underestimated. Careful endoscopic diagnosis before and evaluation of the tumor residue after CSP are recommended when implementing CSP in Japan.Yoji Takeuchi Takeshi Yamashina Noriko Matsuura Takashi Ito Mototsugu Fujii Kengo Nagai Fumi Matsui Tomofumi Akasaka Noboru Hanaoka Koji Higashino Hiroyasu Iishi Ryu Ishihara Henrik Thorlacius Noriya Uedo 2015World Journal of Gastrointestinal Endoscopy2015,7,17:14
11Ratio of mean platelet volume to platelet count is a potential surrogate marker predicting liver cirrhosis显示文摘AIM To provide a simple surrogate marker predictive of liver cirrhosis(LC).METHODS Specimens from 302 patients who underwent resection for hepatocellular carcinoma between January 2006 and December 2012 were retrospectively analyzed. Based on pathologic findings, patients were divided into groups based on whether or not they had LC. Parameters associated with hepatic functional reserve were compared in these two groups using MannWhitney U-test for univariate analysis. Factors differing significantly in univariate analyses were entered into multivariate logistic regression analysis.RESULTS There were significant differences between the LC group(n = 100) and non-LC group(n = 202) in prothrombin activity, concentrations of alanine aminotransferase, aspartate aminotransferase, total bilirubin, albumin, cholinesterase, type Ⅳ collagen, hyaluronic acid, indocyanine green retention rate at 15 min, maximal removal rate of technitium-99 m diethylene triamine pentaacetic acid-galactosyl human serum albumin and ratio of mean platelet volume to platelet count(MPV/PLT). Multivariate analysis showed that prothrombin activity, concentrations of alanine aminotransferase, aspartate aminotransferase, total bilirubin and hyaluronic acid, and MPV/PLT ratio were factors independently predictive of LC. The area under the curve value for MPV/PLT was 0.78,with a 0.8 cutoff value having a sensitivity of 65% and a specificity of 78%.CONCLUSION The MPV/PLT ratio, which can be determined simply from the complete blood count, may be a simple surrogate marker predicting LC.Hiroya Iida Masaki Kaibori Kosuke Matsui Morihiko Ishizaki Masanori Kon 2018World Journal of Hepatology2018,10,1:14

13Endoscopic ultrasonography guided-fine needle aspirationfor the diagnosis of solid pancreaticobiliary lesions:Clinicalaspects to improve the diagnosis显示文摘Endoscopic ultrasonography-guided fine-needle aspiration(EUS-FNA) has been applied to pancreaticobiliary lesions since the 1990 s and is in widespread use throughout the world today. We used this method to confirm the pathological evidence of the pancreaticobiliary lesions and to perform suitable therapies. Complications of EUS-FNA are quite rare, but some of them are severe. Operators should master conventional EUS observation and experience a minimum of 20-30 cases of supervised EUS-FNA on non-pancreatic and pancreatic lesions before attempting solo EUSFNA. Studies conducted on pancreaticobiliary EUSFNA have focused on selection of suitable instruments(e.g., needle selection) and sampling techniques(e.g., fanning method, suction level, with or without a stylet, optimum number of passes). Today, the diagnostic ability of EUS-FNA is still improving; the detection of pancreatic cancer(PC) currently has a sensitivity of 90%-95% and specificity of 95%-100%. In addition to PC, a variety of rare pancreatic tumors can be discriminated by conducting immunohistochemistry on the FNA materials. A flexible, large caliber needle has been used to obtain a large piece of tissue, which can provide sufficient histological information to be helpful in classifying benign pancreatic lesions. EUSFNA can supply high diagnostic yields even for biliary lesions or peri-pancreaticobiliary lymph nodes. This review focuses on the clinical aspects of EUS-FNA in the pancreaticobiliary field, with the aim of providing information that can enable more accurate and efficient diagnosis.Hiroyuki Matsubayashi Toru Matsui Yohei Yabuuchi Kenichiro Imai Masaki Tanaka Naomi Kakushima Keiko Sasaki Hiroyuki Ono 2016World Journal of Gastroenterology2016,22,2:12
14Radiofrequency ablation as treatment for pulmonary metastasis of colorectal cancer显示文摘Radiofrequency ablation(RFA)causes focal coagulation necrosis in tissue.Its first clinical application was reported in 2000,and RFA has since been commonly used in both primary and metastatic lung cancer.The procedure is typically performed using computed tomography guidance,and the techniques for introducing the electrode to the tumor are simple and resemble those used in percutaneous lung biopsy.The most common complication is pneumothorax,which occurs in up to 50%of procedures;chest tube placement for pneumothorax is required in up to 25%of procedures.Other severe complications,such as pleural effusion requiring chest tube placement,infection,and nerve injury,are rare.The local efficacy depends on tumor size,and local progression after RFA is not rare,occurring in 10%or more of patients.The local progression rate is particularly high for tumors>3 cm.Repeat RFA may be used to treat local progression.Short-to mid-term survival after RFA appears promising and is approximately 85%-95%at 1 year and 45%-55% at 3 years.Long-term survival data are sparse.Better survival may be expected for patients with small metastasis,low carcinoembryonic antigen levels,and/or no extrapulmonary metastasis.The notable advantages of RFA are that it is simple and minimally invasive;preserves pulmonary function;can be repeated;and is applicable regardless of previous treatments.Its most substantial limitation is limited local efficacy.Although surgery is still the method of choice for treatment with curative intent,the ultimate application of RFA may be to replace metastasectomy for small metastases.Randomized trials comparing RFA with surgery are needed.Takao Hiraki Hideo Gobara Toshihiro Iguchi Hiroyasu Fujiwara Yusuke Matsui Susumu Kanazawa 2014World Journal of Gastroenterology2014,20,4:12
15Pink-color sign in esophageal squamous neoplasia, and speculation regarding the underlying mechanism显示文摘AIM:To investigate the reasons for the occurrence of the pink-color sign of iodine-unstained lesions. METHODS:In chromoendoscopy, the pink-color sign of iodine-unstained lesions is recognized as useful for the diagnosis of esophageal squamous cell carcinoma. Patients with superficial esophageal neoplasms treated by endoscopic resection were included in the study. Areas of mucosa with and without the pink-color sign were evaluated histologically. The following histologic features that were possibly associated with the pinkcolor sign were evaluated. The keratinous layer and basal cell layer were classified as present or absent. Cellular atypia was classified as high grade, moderate grade or low grade, based on nuclear irregularity, mitotic figures, loss of polarity, chromatin pattern and nuclear/cytoplasmic ratio. Vascular change was assessed based on dilatation, tortuosity, caliber change and variability in shape. Vessels with these four findings were classified as positive for vascular change. Endoscopic images of the lesions were captured immediately after iodine staining, 2-3 min after iodine staining and after complete fading of iodine staining. Quantitative analysis of color changes after iodine staining was also performed. RESULTS:A total of 61 superficial esophageal neoplasms in 54 patients were included in the study. The lesions were located in the cervical esophagus in one case, the upper thoracic esophagus in 10 cases, the mid-thoracic esophagus in 33 cases, and the lower thoracic esophagus in 17 cases. The median diameter of the lesions was 20 mm (range:2-74 mm). Of the 61 lesions, 28 were classified as pink-color sign positive and 33 as pink-color sign negative. The histologic diagnosis was high-grade intraepithelial neoplasia (HGIN) or cancer invading into the lamina propria in 26 of the 28 pink-color sign positive lesions. There was a significant association between pink-color sign positive epithelium and HGIN or invasive cancer (P = 0.0001). Univariate analyses found that absence of the keratinous layer and cellular atypia were significantly associated with the pink-color sign. After Bonferroni correction, there were no significant associations between the pink-color sign and presence of the basal membrane or vascular change. Multivariate analyses found that only absence of the keratinous layer was independently associated with the pink-color sign (OR = 58.8, 95%CI:5.5-632).Quantitative analysis was performed on 10 superficial esophageal neoplasms with both pink-color sign positive and negative areas in 10 patients. Pink-color sign positive mucosa had a lower mean color value in the late phase (pinkish color) than in the early phase (yellowish color), and had similar mean color values in the late and final phases. These findings suggest that pinkcolor positive mucosa underwent color fading from the color of the iodine (yellow) to the color of the mucosa (pink) within 2-3 min after iodine staining. Pink-color sign negative mucosa had similar mean color values in the late and early phases (yellowish color), and had a lower mean color value in the final phase (pinkish color) than in the late phase. These findings suggest that pink-color sign negative mucosa did not undergo color fading during the 2-3 min after iodine staining, and underwent color fading only after spraying of sodium thiosulfate. CONCLUSION:The pink-color sign was associated with absence of the keratinous layer. This sign may be caused by early fading of iodine staining.Ryu Ishihara Hiromitsu Kanzaki Hiroyasu Iishi Kengo Nagai Fumi Matsui Takeshi Yamashina Noriko Matsuura Takashi Ito Mototsugu Fujii Sachiko Yamamoto Noboru Hanaoka Yoji Takeuchi Koji Higashino Noriya Uedo Masaharu Tatsuta Yasuhiko Tomita Shingo Ishiguro 2013World Journal of Gastroenterology2013,19,27:10
16Efficacy of intra-arterial contrast-enhanced ultrasonography during transarterial chemoembolization with drug-eluting beads for hepatocellular carcinoma显示文摘AIM To assess the usefulness of intra-arterial contrastenhanced ultrasonography(IAUS) during transarterial chemoembolization(TACE) with drug-eluting beads(DEB) for hepatocellular carcinoma(HCC).METHODS Thirty two patients with 39 HCC underwent DEB-TACE guided with IAUS, and examined by contrast-enhanced ultrasonography(CEUS) or dynamic CT after DEB-TACE were enrolled in this study. CEUS findings before DEBTACE and IAUS findings were compared. Treatments judged to be complete and incomplete for lesions were appropriate and insufficient, respectively. Findings on CEUS and/or dynamic CT performed 1, 3 and 6 mo after DEB-TACE were evaluated using m RECIST(CR/PR/SD/PD).RESULTS The treatments were complete and incomplete in 26 and 13 lesions, respectively. On imaging evaluation using CEUS and/or dynamic CT one month after treatment, 25 and 1 lesions were judged to be CR and PR, respectively, and at 6 mo after treatment, the results were CR, PR, SD and PD for 24, 1, 0 and 1 of these lesions, respectively, in the 26 completely treated lesions. Of the 13 lesions in which treatment was incomplete, the results on imaging at one month after treatment were CR, PR, SD and PD for 0, 6, 4 and 3 lesions, respectively. The overall CR rate at 6 mo after treatment was 61.5%(24/39).CONCLUSION A combination of DEB-TACE with IAUS can improve the therapeutic effects in patients with HCC.Kazue Shiozawa Manabu Watanabe Takashi Ikehara Shuhei Yamamoto Takashi Matsui Yoshinori Saigusa Yoshinori Igarashi Iruru Maetani 2018World Journal of Hepatology2018,10,1:7
17Role of matricellular proteins in cardiac tissue remodeling after myocardial infarction显示文摘After onset of myocardial infarction(MI),the left ventricle(LV) undergoes a continuum of molecular,cellular,and extracellular responses that result in LV wall thinning,dilatation,and dysfunction.These dynamic changes in LV shape,size,and function are termed cardiac remodeling.If the cardiac healing after MI does not proceed properly,it could lead to cardiac rupture or maladaptive cardiac remodeling,such as further LV dilatation and dysfunction,and ultimately death.Although the precise molecular mechanisms in this cardiac healing process have not been fully elucidated,this process is strictly coordinated by the interaction of cells with their surrounding extracellular matrix(ECM) proteins.The components of ECM include basic structural proteins such as collagen,elastin and specialized proteins such as fibronectin,proteoglycans and matricellular proteins.Matricellular proteins are a class of non-structural and secreted proteins that probably exert regulatory functions through direct binding to cell surface receptors,other matrix proteins,and soluble extracellular factors such as growth factors and cytokines.This small group of proteins,which includesosteopontin,thrombospondin-1/2,tenascin,periostin,and secreted protein,acidic and rich in cysteine,shows a low level of expression in normal adult tissue,but is markedly upregulated during wound healing and tissue remodeling,including MI.In this review,we focus on the regulatory functions of matricellular proteins during cardiac tissue healing and remodeling after MI.Yutaka Matsui Junko Morimoto Toshimitsu Uede 2010World Journal of Biological Chemistry2010,1,5:7

20Measurement of prostaglandin metabolites is useful in diagnosis of small bowel ulcerations显示文摘BACKGROUND We recently reported on a hereditary enteropathy associated with a gene encoding a prostaglandin transporter and referred to as chronic enteropathy associated with SLCO2 A1 gene(CEAS). Crohn's disease(CD) is a major differential diagnosis of CEAS, because these diseases share some clinical features. Therefore, there is a need to develop a convenient screening test to distinguish CEAS from CD.AIM To examine whether prostaglandin E major urinary metabolites(PGE-MUM) can serve as a biomarker to distinguish CEAS from CD.METHODS This was a transactional study of 20 patients with CEAS and 98 patients with CD.CEAS was diagnosed by the confirmation of homozygous or compound heterozygous mutation of SLCO2 A1. We measured the concentration of PGEMUM in spot urine by radioimmunoassay, and the concentration was compared between the two groups of patients. We also determined the optimal cut-off value of PGE-MUM to distinguish CEAS from CD by receiver operating characteristic(ROC) curve analysis.RESULTS Twenty Japanese patients with CEAS and 98 patients with CD were enrolled.PGE-MUM concentration in patients with CEAS was significantly higher than that in patients with CD(median 102.7 vs 27.9 μg/g × Cre, P < 0.0001). One log unit increase in PGE-MUM contributed to 7.3 increase in the likelihood for the diagnosis of CEAS [95% confidence interval(CI) 3.2-16.7]. A logistic regression analysis revealed that the association was significant even after adjusting confounding factors(adjusted odds ratio 29.6, 95%CI 4.7-185.7). ROC curve analysis revealed the optimal PGE-MUM cut-off value for the distinction of CEAS from CD to be 48.9 μg/g × Cre with 95.0% sensitivity and 79.6% specificity.CONCLUSION PGE-MUM measurement is a convenient, non-invasive and useful test for the distinction of CEAS from CD.Yuichi Matsuno Junji Umeno Motohiro Esaki Yoichiro Hirakawa Yuta Fuyuno Yasuharu Okamoto Atsushi Hirano Shigeyoshi Yasukawa Fumihito Hirai Toshiyuki Matsui Shuhei Hosomi Kenji Watanabe Naoki Hosoe Haruhiko Ogata Tadakazu Hisamatsu Shunichi Yanai Shuji Kochi Koichi Kurahara Tsuneyoshi Yao Takehiro Torisu Takanari Kitazono Takayuki Matsumoto 2019World Journal of Gastroenterology2019,25,14:5
