| 1 | Efficacy of mosapride citrate with polyethylene glycol solution for colonoscopy preparation显示文摘AIM:To evaluate the efficacy and safety of adjunctive mosapride citrate for bowel preparation before colonoscopy. METHODS:We conducted a randomized,double-blind, placebo-controlled study with mosapride in addition to polyethylene glycol(PEG)-electrolyte solution.Of 250 patients undergoing colonoscopy,124 were randomized to receive 2 L PEG plus 15 mg of mosapride citrate (mosapride group),and 126 received 2 L PEG plus placebo(placebo group).Patients completed a questionnaire reporting the acceptability and tolerability of the bowel preparation process.The efficacy of bowel preparation was assessed by colonoscopists using a 5-point scale based on Aronchick's criteria.The primary end point was optimal bowel preparation rates(scores of excellent/good/fair vs poor/inadequate). RESULTS:A total of 249 patients were included in the analysis.In the mosapride group,optimal bowel preparation rates were significantly higher in the left colon compared with the placebo group(78.2%vs 65.6%,P<0.05),but not in the right colon(76.5%vs 66.4%,P=0.08).After excluding patients with severe constipation,there was a significant difference in bowel preparation in both the left and right colon(82.4%vs 66.7%,80.8%vs 67.5%,P<0.05,P<0.01).The incidence of adverse events was similar in both groups. Among the subgroup who had previous colonoscopy experience,a significantly higher number of patients in the mosapride group felt that the current preparation was easier compared with patients in the placebo group(34/72 patients vs 24/74 patients,P<0.05). CONCLUSION:Mosapride citrate may be an effective and safe adjunct to PEG-electrolyte solution that leads to improved quality of bowel preparation,especially in patients without severe constipation. | Masahiro Tajika Yasumasa Niwa Vikram Bhatia Hiroki Kawai Shinya Kondo Akira Sawaki Nobumasa Mizuno Kazuo Hara Susumu Hijioka Kazuya Matsumoto Yuji Kobayashi Akira Saeki Asana Akabane Koji Komori Kenji Yamao | 2012 | World Journal of Gastroenterology2012，18，20： | 21 |
| 2 | Cytomegalovirus infection in severe ulcerative colitis patients undergoing continuous intravenous cyclosporine treatment in Japan显示文摘AIM: To investigate active cytomegalovirus (CMV) infection following the cyclosporine A (CyA) treatment of steroid-refractory ulcerative colitis (UC).METHODS: Twenty-three patients with severe UC not responding to steroid therapy (male 14, and female 9) enrolled at Nagoya University Hospital from 1999 to 2005. They received continuous intravenous infusion of CyA (average 4 mg/kg per day) for 1 mo. Serum and colonic biopsy samples were collected before CyA treatment and 4 d, 10 d, 20 d, and 30 d after treatment. Patients were evaluated for CMV by using serology (IgM antibody by ELISA), quantitative real-time PCR for CMV DNA, and histopathological assessment of hematoxylin and eosin (HE)-stained colonic biopsies. CMV infection was indicated by positive results in any test. RESULTS: No patients had active CMV infection before CyA treatment. Eighteen of 23 UC patients treated with CyA were infected with active CMV (IgM antibody in 16/23 patients, 69.6%; CMV DNA in 18/23 patients, 78.2%; and inclusion bodies in 4/23 patients, 17.3%). There was no difference in the active CMV-infection rate between males and females. Active CMV infection was observed after approximately 8 d of CyA treatment, leading to an exacerbation of colitis. Fifteen of these 18 patients with active CMV infection (83.3%) required surgical treatment because of severe deteriorating colitis. Treatment with ganciclovir rendered surgery avoidable in three patients. CONCLUSION: Our results suggest that active CMVinfection in severe UC patients treated with CyA is associated with poor outcome. Further, ganciclovir is useful for treatment of CMV-associated UC after immuno-suppressive therapy. | Masaaki Minami Michio Ohta Teruko Ohkura Takafumi Ando Naoki Ohmiya Yasumasa Niwa Hidemi Goto | 2007 | World Journal of Gastroenterology2007，13，5： | 13 |
| 3 | Clinical utility of the platelet-lymphocyte ratio as a predictor of postoperative complications after radical gastrectomy for clinical T2-4 gastric cancer显示文摘AIM To identify simple and sensitive markers for postoperative complications after gastrectomy, the predictive values were compared among candidate preoperative factors. METHODS Three-hundred and twelve patients with previously untreated clinical T2-4 gastric cancer who underwent a D2 standard gastrectomy(distal gastrectomy or total gastrectomy) were included in the analysis.Correlations between 21 parameters that can be determined by preoperative routine blood tests and clinically relevant postoperative complications(grade Ⅱ or higher according to the Clavien-Dindo classification) were evaluated. The optimal cutoff values and clinical significance of the selected markers were further evaluated by subgroup analyses according to age, body mass index, operative procedure and clinical disease stage.RESULTS Sixty-six patients(21.1%) experienced grade Ⅱ or higher postoperative complications. The plateletlymphocyte ratio(PLR, total lymphocyte count/platelet count × 100) exhibited the highest area under the curve value(0.639) for predicting postoperative complications among the 21 parameters, and the optimal cutoff value was determined to be 0.71(sensitivity = 70%, specificity = 56%). In the univariate analysis, the odds ratio of a low PLR for the occurrence of postoperative complications was 2.94(95%CI: 1.66-5.35, P < 0.001), and a multivariate binomial logistic analysis involving other potential risk factors identified a low PLR as an independent risk factor for postoperative complications(OR = 3.32, 95%CI: 1.82-6.25, P < 0.001). In subgroups classified according to age, body mass index, operative procedure and clinical disease stage, the low PLR group exhibited an increased incidence of postoperative complications. CONCLUSION The preoperative PLR is a simple and useful predictor of complications after curative gastrectomy in patients with clinical T2-4 gastric cancer. | Kenichi Inaoka Mitsuro Kanda Hiroaki Uda Yuri Tanaka Chie Tanaka Daisuke Kobayashi Hideki Takami Naoki Iwata Masamichi Hayashi Yukiko Niwa Suguru Yamada Tsutomu Fujii Hiroyuki Sugimoto Kenta Murotani Michitaka Fujiwara Yasuhiro Kodera | 2017 | World Journal of Gastroenterology2017，23，14： | 13 |
| 4 | Antibody markers in the diagnosis of inflammatory boweldisease显示文摘Inflammatory bowel disease(IBD), including Crohn's disease and ulcerative colitis, is a chronic intestinal inflammation of unknown etiology. The diagnosis of IBD is based on endoscopic, radiologic and histopathologic criteria. Recently, the search for a noninvasive marker that could augment or replace part of this diagnostic process has become a focus of IBD research. In this review, antibody markers, including microbial antibodies, autoantibodies and peptide antibodies, will be described, focusing on their common features. At present, no single marker with qualities that are satisfactory for the diagnosis and treatment of IBD has been identified, although panels of some antibodies are being evaluated with keen interest. The discovery of novel IBD-specific and sensitive markers is anticipated. Such markers could minimize the use of endoscopic and radiologic examinations and could enable clinicians to implement individualized treatment plans designed to improve the long-term prognosis of patients with IBD. | Keiichi Mitsuyama Mikio Niwa Hidetoshi Takedatsu Hiroshi Yamasaki Kotaro Kuwaki Shinichiro Yoshioka Ryosuke Yamauchi Shuhei Fukunaga Takuji Torimura | 2016 | World Journal of Gastroenterology2016，22，3： | 12 |
| 5 | Can mosapride citrate reduce the volume of lavage solution for colonoscopy preparation?显示文摘AIM:To evaluate the possibility of reducing the volume of polyethylene glycol(PEG)-electrolyte solution using adjunctive mosapride citrate for colonoscopy preparation. METHODS:This was a single-center,prospective, randomized,investigator-blinded,non-inferiority study involving 252 patients of both sexes,aged from 20 to 80 years,scheduled for screening or diagnostic colonoscopy in our department.A total of 126 patients was randomized to receive 1.5 L PEG-electrolyte solution plus 15 mg of mosapride(1.5 L group),and 126 received 2 L PEG-electrolyte solution plus 15 mg of mosapride(2 L group).Patients completed a questionnaire on the acceptability and tolerability of the bowel preparation process.The efficacy of bowel preparation was assessed using a 5-point scale based on the Aronchick scale.The primary end point was adequate bowel preparation rates(score of excellent/good/fair) vs(poor/inadequate).Acceptability and tolerability,as well as disease detection,were secondary end points. RESULTS:A total of 244 patients was included in the analysis.There were no significant differences between the 2 L and 1.5 L groups in age,sex,body mass index, number of previous colonoscopies,and the preparation method used previously.The adequate bowel preparation rates were 88.5%in the 2 L group and 82.8%in the 1.5 L group[95%lower confidence limit(LCL)for the difference=-14.5%,non-inferiority P=0.019]in the right colon.In the left colon,the adequate bowel preparation rates were 89.3%in the 2 L group and 81.1%in the 1.5 L group(95%LCL=-17.0%,non-inferiority P=0.066).Compliance,defined as complete (100%)intake of the PEG solution,was significantly higher in the 1.5 L group than in the 2 L group(96.8% vs 85.7%,P=0.002).The proportion of abdominal distension(none/mild/moderate/severe)was significantly lower in the 1.5 L group than in the 2 L group (36/65/22/3 vs 58/48/18/2,P=0.040).Within the subgroup who had undergone colonoscopy previously, a significantly higher number of patients in the 1.5 L group than in the 2 L group felt that the current preparation was easier than the previous one(54.1%vs 28.0%,P=0.001).The disease detection rate was not significantly different between the two groups. CONCLUSION:Although the 1.5 L group had better acceptability and tolerability,15 mg of mosapride may be insufficient to compensate for a 0.5-L reduction of PEG solution. | Masahiro Tajika Yasumasa Niwa Vikram Bhatia Shinya Kondo Tsutomu Tanaka Nobumasa Mizuno Kazuo Hara Susumu Hijioka Hiroshi Imaoka Koji Komori Kenji Yamao | 2013 | World Journal of Gastroenterology2013，19，5： | 8 |
| 6 | Clinical relevance of fluorodeoxyglucose positron emission tomography/computed tomography and magnifying endoscopy with narrow band imaging in decision-making regarding the treatment strategy for esophageal squamous cell carcinoma显示文摘BACKGROUND Recent advances in endoscopic technology,especially magnifying endoscopy with narrow band imaging(ME-NBI)enable us to detect superficial esophageal squamous cell carcinoma(ESCC),but determining the appropriate method of resection,endoscopic resection(ER)vs surgical resection,is often challenging.Recently,several studies have reported that 18F-fluorodeoxyglucose positron emission tomography(FDG-PET)is a useful indicator for decision-making regarding treatment for superficial ESCC.Although,there are not enough reports on association between FDG-PET uptake and clinicopathological characteristics of superficial ESCC.And,there are not enough reports on evaluating the usefulness of combination of FDG-PET and ME-NBI for determining the treatment strategy for superficial ESCC.This study evaluated clinical relevance of FDG-PET and ME-NBI in decision-making regarding the treatment strategy for ESCC.AIM To investigate the association between FDG uptake and the clinicopathological characteristics of superficial ESCC and its usefulness of combination of FDG-PET and ME-NBI for determining the treatment strategy for superficial ESCC.METHODS A database of all patients with superficial ESCC who had undergone both MENBI and FDG-PET for pre-treatment staging at Aichi Cancer Center Hospital between January 2008 and November 2018 was retrospectively analyzed.FDG uptake was defined positive or negative whether the primary lesion was visualized or could be distinguished from the background,or not.The invasion depth of ESCC was classified according to the Japan Esophageal Society.Primary endpoint is to evaluate the association between FDG uptake and clinicopathological characteristics of superficial ESCC.Secondary endpoint is to investigate the efficacy of combination of FDG-PET and ME-NBI for determining the treatment strategy for superficial ESCC.RESULTS A total of 82 lesions in 82 patients were included.FDG-PET showed positive uptake in 29(35.4%)lesions.Univariate analysis showed that uptake of FDG-PET had significant correlations with circumferential extension(P=0.014),pathological depth of tumor invasion(P<0.001),infiltrative growth pattern(P<0.001),histological grade(P=0.002),vascular invasion(P=0.001),and lymphatic invasion(P<0.001).On multivariate analysis,only depth of tumor invasion was independently correlated with FDG-PET/computed tomography visibility(P=0.018).The sensitivity,specificity,positive predictive value(PPV),negative predictive value(NPV),and accuracy of Type B2 in ME-NBI for the invasion depth of T1a muscularis mucosae and T1b upper submucosal layer were 68.4%/79.4%/50.0%/89.3%/76.8%,respectively,and those of Type B3 for the depth of T1b middle and deeper submucosal layers(SM2 and SM3)were 46.7%/100%/100%/89.3%/90.2%,respectively.On the other hand,those of FDGPET for SM2 and SM3 were 93.3%/77.6%/48.2%/98.1%/80.5%,respectively,whereas,if the combination of positive FDG uptake and type B2 and B3 was defined as an indicator for radical esophagectomy or definitive chemoradiotherapy,the sensitivity,specificity,PPV,NPV,and accuracy were 78.3%/91.5%/78.3%/91.5%/87.8%,respectively.CONCLUSION FDG uptake was correlated with the invasion depth of superficial ESCC.Combined use of FDG-PET and ME-NBI,especially with the microvascular findings of Type B2 and B3,is useful to determine whether ER is indicated for the lesion. | Kazuhiro Toriyama Masahiro Tajika Tsutomu Tanaka Makoto Ishihara Yutaka Hirayama Sachiyo Onishi Nobumasa Mizuno Takamichi Kuwahara Nozomi Okuno Shinpei Matsumoto Eiichi Sasaki Tetsuya Abe Yasushi Yatabe Kazuo Hara Keitaro Matsuo Tsuneo Tamaki Yasumasa Niwa | 2019 | World Journal of Gastroenterology2019，25，46： | 7 |
| 7 | Use of color Doppler ultrasonography in the diagnosis of anomalous connection in pancreatobiliary disease显示文摘AIM: To estimate the detectability of anomalous connection in pancreatobiliary disease (ACPBD) cases, measuring gallbladder wall blood flow (GWBF).METHODS: In the retrospective study, we enrolled 42subjects with gallbladder wall thickening. GWBF velocity was determined as an average value of the peak velocity of color signals on the gallbladder wall, three times in each case. Based on the findings on endoscopic ultrasonography (EUS) or endoscopic retrograde cholangiopancreatography (ERCP), the 42 subjects were divided into 11 cases with ACPBD and 31 cases without ACPBD. In the prospective study, the subjects were 92 cases with gallbladder wall thickening. Using the cut-off level of the flow velocity obtained in the retrospective study, the usefulness of measuring GWBF velocity in diagnosing ACPBD was evaluated.RESULTS: In the retrospective study, imaging of GWBF was obtained in 40 of the 42 subjects. The mean GWBF velocity of the ACPBD cases was 29.4±3.9 cm/s(mean±SD), which was significantly different (P<0.0001;95% CI 5.48-13.2) from that of the without ACPBD cases(20.1±5.9 cm/s). Based on this result, we prepared a receiver operating characteristic curve, and the cut-off level appropriate for diagnosing ACPBD was estimated to be 25 cm/s. In the prospective study, GWBF was detected in 86 of the 92 subjects. Based on the EUS or ERCP findings, the 92 subjects were divided into 15 cases with ACPBD and 77 cases without ACPBD. When a cut-off level of 25 cm/s was employed, ACPBD could be diagnosed with a sensitivity of 87.0% (13/15) and a specificity of87.3% (62/71).CONCLUSION: Measurement of GWBF velocity, which is less invasive and provides objective values, is very useful for diagnosing ACPBD prior to the development of malignant tumors in cases with gallbladder wall thickening. | Hiroki Kawashima Yoshiki Hirooka Akihiro Itoh Senju Hashimoto Terutomo Itoh Kazuo Hara Akira Kanamori Naoki Ohmiya Yasumasa Niwa Hidemi Goto | 2005 | World Journal of Gastroenterology2005，11，7： | 7 |
| 8 | Combined choriocarcinoma, neuroendocrine cell carcinoma and tubular adenocarcinoma in the stomach显示文摘We described a patient with adenocarcinoma of the stomach combined with choriocarcinoma and neuroendocrine cell carcinoma. An 85-year-old man visited our hospital because of appetite loss. Gastric fiberscopy revealed a large tumor occupying the cardial region and anterior wall of the gastric body. The patient underwent total gastrectomy with lymphnode dissection and partial resection of the liver. Choriocarcinoma, small cell carcinoma and tubular adenocarcinoma existed in the gastric tumor. The choriocarcinomatous foci contained cells positive for beta-subunit of human chorionic gonadotropin (B-hCG) and human placental lactogen mainly in syncytiotrophoblastic cells. The small cell carcinomatous foci contained cells positive for synaptophysin, neuron-specific enolase (NSE), and chromogranin A. The prognosis for gastric adenocarcinoma with choriocarcinoma and neuroendocrine cell carcinoma is exceedingly poor. This patient died about 2 mo after the first complaint from hepatic failure. This is the first reported case of gastric cancer with these three pathological features. | Yasumitsu Hirano Takuo Hara Hiroshi Nozawa Kaeko Oyama Naohiro Ohta Kenji Omura Go Watanabe Hideki Niwa | 2008 | World Journal of Gastroenterology2008，14，20： | 6 |

| 10 | endoscopic ultrasonography-guided biliary drainage:Who,when,which,and how?显示文摘Both endoscopic ultrasonography(EUS)-guided choledochoduodenostomy( EUS- CDS) and EUS-guided hepaticogastrostomy(EUS-HGS) are relatively well established as alternatives to percutaneous transhepatic biliary drainage(PTBD). Both EUSCDS and EUS-HGS have high technical and clinical success rates(more than 90%) in high-volume centers. Complications for both procedures remain high at 10%-30%. Procedures performed by endoscopists who have done fewer than 20 cases sometimes result in severe or fatal complications. When learning EUSguided biliary drainage(EUS-BD), we recommend a mentor's supervision during at least the first 20 cases. For inoperable malignant lower biliary obstruction, a skillful endoscopist should perform EUS-BD before EUS-guided rendezvous technique(EUS-RV) and PTBD. We should be select EUS-BD for patients having altered anatomy from malignant tumors before balloon-enteroscope-assisted endoscopic retrograde cholangiopancreatography, EUS-RV, and PTBD. If both EUS-CDS and EUS-HGS are available, we should select EUS-CDS, according to published data. EUSBD will potentially become a first-line biliary drainage procedure in the near future. | Kazuo Hara Kenji Yamao Nobumasa Mizuno Susumu Hijioka Hiroshi Imaoka Masahiro Tajika Tutomu Tanaka Makoto Ishihara Nozomi Okuno Nobuhiro Hieda Tukasa Yoshida Yasumasa Niwa | 2016 | World Journal of Gastroenterology2016，22，3： | 4 |

| 12 | Risk of ileal pouch neoplasms in patients with familial adenomatous polyposis显示文摘Restorative proctocolectomy is the most common surgical option for patients with familial adenomatous polyposis(FAP). However,adenomas may develop in the ileal pouch mucosa over time,and even carcinoma in the pouch has been reported. We therefore reviewed the prevalence,nature,and treatment of adenomas and carcinoma that develop after proctocolectomy in the ileal pouch mucosa in patients with FAP. In 25 reports that were reviewed,the incidence of adenomas in the ileal pouch varied from 6.7% to 73.9%. Several potential factors that favor the development of pouch polyposis have been investigated,but many remain controversial. Nevertheless,it seems certain that the age of the pouch is important. The risk appears to be 7%to 16% after 5 years,35% to 42% after 10 years,and75% after 15 years. On the other hand,only 21 cases of ileal pouch carcinoma have been recorded in the literature to date. The diagnosis of pouch carcinoma was made between 3 to 20 years(median,10 years) after pouch construction. Although the risk of malignant transformation in ileal pouches is probably low,it is not negligible,and the long-term risk cannot presently be well quantified. Regular endoscopic surveillance,especially using chromoendoscopy,is recommended. | Masahiro Tajika Yasumasa Niwa Vikram Bhatia Tsutomu Tanaka Makoto Ishihara Kenji Yamao | 2013 | World Journal of Gastroenterology2013，19，40： | 4 |

| 15 | 疑似小肠出血患者经胶囊内镜和双球囊肠镜检查结果的初步比较显示文摘Background and study aims: Capsule endoscopy (CE) and double-balloon enteroscopy (DBE) have been introduced as modalities for examining the entire small bowel. The aim of the present study was to assess the clinical effects of CE and DBE to consider the roles of CE and DBE and the indications for the procedures in patients with suspected small-bowel bleeding. Patients and methods: Between June 2004 and January 2005,32 patients in whom a site of bleeding in the gastrointestinal tract had not been identified were enrolled in the study. Twenty-eight patients were examined with both methods. Bleeding sources were categorized as either A1 lesions (immediate hemostatic procedures required) or A2 lesions (close observation required). CE and DBE were evaluated with regard to whether or not they were capable of accessing the entire small bowel and provided a diagnosis, and the access and diagnostic rates were calculated. Results: On CE, 13 patients were diagnosed with A1 lesions and six with A2 lesions; on DBE, 11 had A1 lesions and one had an A2 lesion. The access rate for the entire small intestine on CE was 90.6% (29 of 32), significantly higher than with DBE at 62.5% (10 of 16; P < 0.05). The diagnostic rate on CE was 59.4% (19 of 32), higher than with DBE at 42.9% (12 of 28; P = 0.30), but not significantly different. Among patients with A1 lesions who were diagnosed with DBE, histological diagnoses were obtained in six of the 11, and three patients were treated. Conclusions: In many suspected small-bowel bleeding cases, CE should be selected for the initial diagnosis and DBE for treatment or histopathological diagnosis after detection of the bleeding site on | Nakamura M.

| 16 | Autonomic nervous system network and liver regeneration显示文摘To date, various signal transducers, cytokines, growth factors, and hormones have been reported to play an important role in homeostasis of various organs. Various cells and organs are involved in the hepatic regeneration process, which proceeds as a result of the coordination of many factors. While these factors are well known to be involved in the liver regeneration after the liver injury, however, as the details of such mechanisms have not been sufficiently elucidated, the practical applicability of hepatic regeneration based on the action of these and cytokines growth factors is still unclear. In terms of the involvement of the autonomic nervous system in hepatic regeneration, cell proliferation resulting from direct signal transduction to the liver has also been reported and recent studies focusing on the inter-organ communication via neural network opened a novel aspect of this field for therapeutic applicability. Therefore, the appropriate understanding of the relationship between autonomic neural network and liver regeneration through various organs including brain, afferent nerve, efferent nerve, etc. is essential. This mini-review explains the principle of neural system involved in the inter-organ communication and its contribution on the liver regeneration upon the liver injury reviewing recent progress in this field. | Kenya Kamimura Ryosuke Inoue Takuro Nagoya Norihiro Sakai Ryo Goto Masayoshi Ko Yusuke Niwa Shuji Terai | 2018 | World Journal of Gastroenterology2018，24，15： | 3 |

| 18 | Magnifying chromoscopy, a novel and useful technique for colonoscopy in ulcerative colitis显示文摘Ulcerative colitis (UC) is a chronic inflammatory bowel disorder characterized by exacerbations and remissions. The degree of inflammation as assessed by conventional colonoscopy is a reliable parameter of disease activity. However, even when conventional colonoscopy suggests remission and normal mucosal findings, microscopic abnormalities may persist, and relapse may occur later. Patients with long-standing, extensive ulcerative colitis have an increased risk of developing colorectal cancer. Ulcerative colitis-associated colorectal cancer is characterized by an early age at onset, poorly differentiated tumor cells, mucinous carcinoma, and multiple lesions. Early detection of dysplasia and colitic cancer is thus a prerequisite for survival. A relatively new method, magnifying chromoscopy, is thought to be useful for the early detection and diagnosis of dysplasia and colitic cancer, as well as the prediction of relapse. | Takafumi Ando Hironao Takahashi Osamu Watanabe Osamu Maeda Kazuhiro Ishiguro Daisuke Ishikawa Motofusa Hasegawa Naoki Ohmiya Yasumasa Niwa Hidemi Goto | 2007 | World Journal of Gastroenterology2007，13，18： | 3 |
