| 1 | 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 |
| 2 | Factors associated with the overall survival of elderly patients with hepatocellular carcinoma显示文摘AIM:To identify the factors associated with overall survival of elderly patients with hepatocellular carcinoma(HCC).METHODS:A total of 286 patients with HCC(male/female:178/108,age:46-100 years),who were diagnosed and treated by appropriate therapeutic procedures between January 2000 and December 2010,were enrolled in this study.Patients were stratified into two groups on the basis of age:Elderly(≥ 75 years old) and non-elderly(< 75 years old).Baseline clinical characteristics as well as cumulative survival rates were then compared between the two groups.Univariate and multivariate analyses were used to identify the factors associated with prolonged overall survival of patients in each group.Cumulative survival rates in the two groups were calculated separately for each modified Japan Integrated Stage score(mJIS score) category by the Kaplan-Meier method.In addition,we compared the cumulative survival rates of elderly and non-elderly patients with good hepatic reserve capacity(≤ 2 points as per mJIS).RESULTS:In the elderly group,the proportion of female patients,patients with absence of hepatitis B or hepatitis C viral infection,and patients with coexisting extrahepatic comorbid illness was higher(56.8% vs 31.1%,P < 0.001;27.0% vs 16.0%,P = 0.038;33.8% vs 22.2%,P = 0.047;respectively) than that in the nonelderly group.In the non-elderly group,the proportion of hepatitis B virus(HBV)-infected patients was higher than that in the elderly group(9.4% vs 0%,P = 0.006).The cumulative survival rates in the elderly group were 53.7% at 3 years and 32.9% at 5 years,which were equivalent to those in the non-elderly group(55.9% and 39.4%,respectively),as shown by a log-rank test(P = 0.601).In multivariate analysis,prolonged survival was significantly associated with the extent of liver damage and stage(P < 0.001 and P < 0.001,respectively),but was not associated with patient age.However,on individual evaluation of factors in both groups,stage was significantly(P < 0.001) associated with prolonged survival.Regarding mJIS scores of ≤ 2,the rate of female patients with this score was higher in the elderly group when compared to that in the non-elderly group(P = 0.012) and patients ≥ 80 years of age tended to demonstrate shortened survival.CONCLUSION:Survival of elderly HCC patients was associated with liver damage and stage,but not age,except for patients ≥ 80 years with mJIS score ≤ 2. | Hideki Fujii Yoshito Itoh Naoki Ohnishi Masafumi Sakamoto Tohru Ohkawara Yoshihiko Sawa Koichi Nishida Yasuo Ohkawara Kanji Yamaguchi Masahito Minami Takeshi Okanoue | 2012 | World Journal of Gastroenterology2012，18，16： | 4 |
| 3 | Screening for hilar biliary invasion in ampullary cancer patients显示文摘BACKGROUND The treatment for ampullary cancer is pancreatoduodenectomy or local ampullectomy.However,effective methods for the preoperative investigation of hilar biliary invasion in ampullary cancer patients have not yet been identified.AIM To determine the necessity of and an appropriate method for investigating hilar biliary invasion of ampullary cancer.METHODS Among 43 ampullary cancer patients,34 underwent endoscopic treatment(n=9)or surgery(n=25).The use of imaging findings(thickening and enhancement of the bile duct wall on contrast-enhanced computed tomography,irregularity on endoscopic retrograde cholangiography,thickening of the entire bile duct wall on intraductal ultrasonography(IDUS),and partial thickening of the bile duct wall on IDUS)and biliary biopsy results for diagnosing hilar biliary invasion of ampullary cancer was compared.RESULTS Hilar invasion was not observed in every patient.Among the patients who did not undergo biliary stent insertion,the combination of partial thickening of the bile duct wall on IDUS and biliary biopsy results showed the highest accuracy(100%)for diagnosing hilar biliary invasion.However,each imaging method and biliary biopsy yielded some false-positive results.CONCLUSION Although some false-positive results were obtained with each method,the combination of partial thickening of the bile duct wall on IDUS and biliary biopsy results was useful for diagnosing hilar biliary invasion of ampullary cancer.However,hilar invasion of ampullary cancer is rare;therefore,the investigation of hilar biliary invasion of ampullary cancer might be unnecessary. | Tadayuki Takagi Mitsuru Sugimoto Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Jun Nakamura Mika Takasumi Minami Hashimoto Tsunetaka Kato Ryoichiro Kobashi Takumi Yanagita Yuko Hashimoto Shigeru Marubashi Takuto Hikichi Hiromasa Ohira | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，9： | 2 |

| 10 | Can the wet suction technique change the efficacy of endoscopic ultrasound-guided fine-needle aspiration for diagnosing autoimmune pancreatitis type 1? A prospective single-arm study显示文摘BACKGROUND Other than surgery,endoscopic ultrasound-guided fine-needle aspiration(EUSFNA)is the only procedure for histologically diagnosing autoimmune pancreatitis(AIP).However,adequate specimens are difficult to obtain.Recently,more adequate specimens were reported to be obtained with EUS-FNA with a wet suction technique(WEST)than with conventional EUS-FNA.AIM To histologically diagnose AIP by EUS-FNA with a WEST.METHODS Eleven patients with possible type 1 AIP between February 2016 and August 2018 underwent EUS-FNA with a WEST(WEST group),with four punctures by 19 or 22 G needles.As a historical control,23 type 1 AIP patients who underwent no fewer than four punctures with 19 or 22 G needles were enrolled(DRY group).Patient characteristics and histological findings were compared between the two groups.RESULTS Three histopathological factors according to the International Consensus Diagnostic Criteria were significantly greater in the WEST group than the DRY group[lymphoplasmacytic infiltrate without granulocytic infiltration:9(81.8%)vs 6(26.1%),P=0.003,storiform fibrosis:5(45.5%)vs 1(4.3%),P=0.008,abundant(>10 cells/HPF)IgG4-positive cells:7(63.6%)vs 5(21.7%),P=0.026].Level 1 or level 2 histopathological findings were observed more often in the WEST group than in the DRY group[8(72.7%)vs 3(13.0%),P=0.001].CONCLUSION EUS-FNA with a WEST was more successful than standard EUS-FNA in histologically diagnosing AIP. | Mitsuru Sugimoto Tadayuki Takagi Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Ko Watanabe Jun Nakamura Hitomi Kikuchi Mika Takasumi Minami Hashimoto Tsunetaka Kato Takuto Hikichi Kenji Notohara Hiromasa Ohira | 2020 | World Journal of Clinical Cases2020，8，1： | 1 |

| 15 | Appropriate number of biliary biopsies and endoscopic retrograde cholangiopancreatography sessions for diagnosing biliary tract cancer显示文摘BACKGROUND Biliary ductal cancer(BDC) is a lethal disease; however, diagnosing BDC is challenging. Biliary biopsies are performed to pathologically diagnose BDC, but the appropriate parameters for biliary biopsy [number of biliary biopsies, number of endoscopic retrograde cholangiopancreatography(ERCP) sessions, etc.] are unknown.AIM To clarify what constitutes an adequate method for biliary biopsy.METHODS In total, 95 patients who underwent endoscopic biliary biopsy without choledochoscopy and who were pathologically diagnosed with BDC were enrolled in this study. The patients were divided into two groups. Seventy-six patients who were diagnosed by biliary biopsy were defined as the positive group(P group), and nineteen patients who were not diagnosed by biliary biopsy were defined as the negative group(N group). The patient characteristics and ERCP-related procedures were compared between the P and N groups.RESULTS The numbers of ERCP sessions and biliary biopsies were significantly different between the two groups [ERCP sessions(one/two), P group 72/4 vs N group15/4, P value = 0.048; number of biliary biopsies, P group 2(1-6) vs N group 2(1-7), P value = 0.039]. In a multivariate analysis, fewer than 2 ERCP sessions was an independent factor influencing the positivity of the biliary biopsies.CONCLUSION This study clarified that ERCP and biliary ductal biopsy should only be performed once. If biliary cancer is not pathologically diagnosed after the first ERCP session, other methods(Endoscopic ultrasonography-guided fine needle aspiration or choledochoscopy-guided biliary ductal biopsy) should be employed. | Tadayuki Takagi Mitsuru Sugimoto Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Ko Watanabe Jun Nakamura Hitomi Kikuchi Mika Takasumi Minami Hashimoto Takuto Hikichi Hiromasa Ohira | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，3： | 1 |

| 17 | Pancreatic stents to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis: A meta-analysis显示文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP)plays a major role in the investigation and treatment of pancreaticobiliary diseases.However,post-ERCP pancreatitis(PEP)is a severe adverse effect.Prior meta-analyses have shown that prophylactic PS was useful for preventing PEP.However,abstract reports and patients who underwent endoscopic ampullectomy were included in the previous analyses.In addition,two meta-analyses involved non-randomized controlled trials(RCTs).The efficacy of PS for preventing severe PEP was different in each meta-analysis.Therefore,we performed the current metaanalysis,which included only full-text articles,and added new findings.AIM To reveal the efficacy of prophylactic pancreatic stent(PS)placement for preventing PEP.METHODS We searched the MEDLINE,Cochrane Library and PubMed databases for related RCTs.Among the reports retrieved,11 studies were included in this metaanalysis.All full-text articles were published between 1993 and 2016.A total of 1475 patients were enrolled in the included studies;of these patients,734 had a PS inserted,and 741 did not have a PS inserted.PEP and severe PEP occurrence were evaluated in this meta-analysis.RESULTS PEP was observed in all studies and occurred in 39(5.3%)patients who received a PS.On the other hand,PEP occurred in 141(19%)patients who did not receive a PS.The occurrence of PEP was significantly lower in the patients who underwent PS placement than in the patients who did not receive a PS(OR=0.32;95%CI:0.23-0.45;P<0.001).In addition,the occurrence of severe PEP was evaluated.Notably,the occurrence of severe PEP was not observed in the stent group;however,the occurrence of severe PEP was observed in 8(1.3%)patients who did not have a PS inserted.Severe PEP occurred significantly less often in the stent group than in the no stent group(OR=0.24;95%CI:0.06-0.94;P=0.04).CONCLUSION In conclusion,prophylactic PS placement is useful for preventing PEP and severe PEP. | Mitsuru Sugimoto Tadayuki Takagi Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Ko Watanabe Jun Nakamura Hitomi Kikuchi Mika Takasumi Minami Hashimoto Takuto Hikichi Hiromasa Ohira | 2019 | World Journal of Meta-Analysis2019，7，5： | 1 |

| 19 | Present Status of the Nd:YAG Thomson Scattering System Development for Time Evolution Measurement of Plasma Profile on Heliotron J显示文摘A new high repetition rate Nd:YAG Thomson scattering system is developed for the Heliotron J helical device.A main purpose of installing the new system is the temporal evolution measurement of a plasma profile for improved confinement physics such as the edge transport barrier (H-mode) or the internal transport barrier of the helical plasma.The system has 25 spatial points with ~10mm resolution.Two high repetition Nd:YAG lasers (>550mJ@ 50Hz) realize the measurement of the time evolution of the plasma profile with ~10ms time intervals.Scattered light is collected by a large concave mirror (D=800 mm,f/2.25) with a solid angle of ~100 mstr and transferred to interference filter polychromators by optical fiber bundles in a staircase form.The signal is amplified by newly designed fast preamplifiers with DC and AC output,which reduces the low frequency background noise.The signals are digitized with a multi-event QDC,fast gated integrators.The data acquisition is performed by a VME-based system operated by the CINOS. | Takashi MINAMI Shohei ARAI Naoki KENMOCHI Hiroaki YASHIRO Chihiro TAKAHASHI Shinji KOBAYASHI Tohru MIZUUCHI Shinsuke OHSHIMA Satoshi YAMAMOTO Hiroyuki OKADA Kazunobu NAGASAKI Yuji NAKAMURA Kiyoshi HANATANI Shigeru KONOSHIMA Fumimichi SANO | 2013 | Plasma Science and Technology2013，15，3： | 0 |
| 20 | Prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis using pancreatic stents: A review of efficacy, diameter and length显示文摘Although endoscopic retrograde cholangiopancreatography (ERCP) is an important procedure for the diagnosis and treatment of pancreaticobiliary diseases, post-ERCP pancreatitis (PEP) is the most frequent adverse event that can sometimes be fatal. However, prophylactic pancreatic stent (PS) insertion has been performed to prevent PEP in high-risk patients. In some randomized controlled trials (RCTs) and meta-analyses, the efficacy of prophylactic PS insertion has been shown to prevent PEP. In addition, several types of stents have been used to decrease PEP. In this review, we introduce the details of these RCTs and meta-analyses and reveal the specifications for stent placement, for example, the stent diameter and length and the pancreatic region into which the stent should be inserted. | Mitsuru Sugimoto Tadayuki Takagi Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Ko Watanabe Jun Nakamura Hitomi Kikuchi Mika Takasumi Minami Hashimoto Takuto Hikichi Hiromasa Ohira | 2019 | World Journal of Meta-Analysis2019，7，6： | 0 |
