| 1 | Effectiveness of probiotic therapy for the prevention of relapse in patients with inactive ulcerative colitis显示文摘AIM: to evaluate the effectiveness of probiotic therapy for suppressing relapse in patients with inactive ulcerative colitis(UC).METHODS: Bio-Three tablets, each containing 2 mg of lactomin(Streptococcus faecalis T-110), 10 mg of Clostridium butyricum TO-A, and 10 mg of Bacillus mesentericus TO-A, were used as probiotic therapy.Sixty outpatients with UC in remission were randomly assigned to receive 9 Bio-Three tablets/day(BioThree group) or 9 placebo tablets/day(placebo group)for 12 mo in addition to their ongoing medications.Clinical symptoms were evaluated monthly or on the exacerbation of symptoms or need for additional medication. Fecal samples were collected to analyze bacterial DNA at baseline and 3-mo intervals. Terminal restriction fragment length polymorphism and cluster analyses were done to examine bacterial components of the fecal microflora.RESULTS: Forty-six patients, 23 in each group,completed the study, and 14 were excluded. The relapse rates in the Bio-Three and placebo groups were respectively 0.0% vs 17.4% at 3 mo(P = 0.036), 8.7%vs 26.1% at 6 mo(P = 0.119), and 21.7% vs 34.8%(P = 0.326) at 9 mo. At 12 mo, the remission rate was 69.5% in the Bio-Three group and 56.6% in the placebo group(P = 0.248). On cluster analysis of fecal flora, 7 patients belonged to cluster Ⅰ, 32 to cluster Ⅱ,and 7 to cluster Ⅲ.CONCLUSION: Probiotics may be effective formaintaining clinical remission in patients with quiescent UC, especially those who belong to cluster Ⅰ on fecal bacterial analysis. | Yasushi Yoshimatsu Akihiro Yamada Ryuichi Furukawa Koji Sono Aisaku Osamura Kentaro Nakamura Hiroshi Aoki Yukiko Tsuda Nobuo Hosoe Nobuo Takada Yasuo Suzuki | 2015 | World Journal of Gastroenterology2015，21，19： | 21 |
| 2 | Multicenter study of endoscopic preoperative biliary drainage for malignant distal biliary obstruction显示文摘AIM: To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal biliary obstruction.METHODS: Multicenter retrospective study was conducted in patients who underwent plastic stent(PS) or nasobiliary catheter(NBC) placement for resectable malignant distal biliary obstruction followed by surgery between January 2010 and March 2012. Procedurerelated adverse events, stent/catheter dysfunction(occlusion or migration of PS/NBC, developmentof cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution(bilirubin level < 3.0 mg/d L) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis.RESULTS: In total, 419 patients were included in the study(PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients(46%), bile duct cancer in 172(41%), gallbladder cancer in three(1%), and ampullary cancer in 50(12%). The median serum total bilirubin was 7.8 mg/d L and 324 patients(77%) had ≥ 3.0 mg/d L. During the median time to surgery of 29 d [interquartile range(IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio(SHR) = 4.76; 95%CI: 2.44-10.0, P < 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method(PS or NBC).CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored. | Naoki Sasahira Tsuyoshi Hamada Osamu Togawa Ryuichi Yamamoto Tomohisa Iwai Kiichi Tamada Yoshiaki Kawaguchi Kenji Shimura Takero Koike Yu Yoshida Kazuya Sugimori Shomei Ryozawa Toshiharu Kakimoto Ko Nishikawa Katsuya Kitamura Tsunao Imamura Masafumi Mizuide Nobuo Toda Iruru Maetani Yuji Sakai Takao Itoi Masatsugu Nagahama Yousuke Nakai Hiroyuki Isayama | 2016 | World Journal of Gastroenterology2016，22，14： | 18 |
| 3 | Branched-chain amino acid treatment before transcatheter arterial chemoembolization for hepatocellular carcinoma显示文摘AIM:To examine the significance of branched-chain amino acid (BCAA) treatment before transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).METHODS:This study included 99 patients who underwent TACE therapy for HCC at our hospital and were followed up without treatment for at least 6 mo between January 2004 and January 2010.They were divided into 2 groups:those receiving BCAA granules (n=40) or regular diet (n=59,control).Data obtained were retrospectively analyzed (prior to TACE,and 1 wk,1,3,and 6 mo after TACE) in terms of nutritional condition and clinical laboratory parameters (serum albumin level and Child-Pugh score),both of which are determinants of hepatic functional reserve.RESULTS:The BCAA group comprised 27 males and 13 females with a mean age of 69.9 ± 8.8 years.The patients of the BCAA group were classified as follows:Child-Pugh A/B/C in 22/15/3 patients,and Stage Ⅱ/Ⅲ /ⅣA HCC in 12/23/5 patients,respectively.The controlgroup comprised 32 males and 27 females with a mean age of 73.2 ± 10.1 years.In the control group,9 patients had chronic hepatitis,Child-Pugh A/B/C in 39/10/1 patients,and StageⅠ/Ⅱ/Ⅲ/ⅣA HCC in 1/11/35/12 patients,respectively.Overall,both serum albumin level and Child-Pugh score improved significantly in the BCAA group as compared with the control 3 and 6 mo after TACE (P < 0.05).Further analysis was performed by the following categorization:(1) child-Pugh classification;(2) liver cirrhosis subgroup with a serum albumin level > 3.5 g/dL;and (3) epirubicin dose.A similar trend indicating a significant improvement of all variables in the BCAA group was noted (P < 0.05).CONCLUSION:Treatment with BCAA granules in patients who have undergone TACE for HCC is considered useful to maintain their hepatic functional reserve. | Hiroki Nishikawa Yukio Osaki Tadashi Inuzuka Haruhiko Takeda Jun Nakajima Fumihiro Matsuda Shinichiro Henmi Azusa Sakamoto Tetsuro Ishikawa Sumio Saito Ryuichi Kita Toru Kimura | 2012 | World Journal of Gastroenterology2012，18，12： | 16 |
| 4 | Comparison of endoscopic stenting for malignant biliary obstruction: A single-center study显示文摘AIM: To evaluate the efficacy and safety of single-step endoscopic placement of self-expandable metallic stents(SEMS) for treatment of obstructive jaundice.METHODS: A retrospective study was performed among 90 patients who underwent transpapillary biliary metallic stent placement for malignant biliary obstruction(MBO) between April 2005 and October 2012. The diagnosis of primary disease and MBO was based on abdominal ultrasound, computed tomography, magnetic resonance imaging, endoscopic ultrasound, endoscopic retrograde cholangiopancreatography with brush cytology, biopsy, and/or a combination of these modalities. The type of SEMS(covered or non-covered, 8 mm or 10 mm in diameter) was determined by the endoscopist. Ninety patients were divided into two groups: group 1(49 patients) who underwent a singlestep SEMS placement and group 2(41 patients) who underwent a two-step SEMS placement. The technical success rate, complication rate, stent patency, and patient survival rate were compared between the groups. In addition, to identify the clinical prognostic factors associated with patient survival, the following variables were evaluated in Cox-regression analysis: gender, age, etiology of MBO(pancreatic cancer or nonpancreatic cancer), clinical stage(Ⅳb; with distant metastases or Ⅳa >; without distant metastases), chemotherapy(with or without), patency of the stent, and the use of single-step or two-step SEMS. RESULTS: Immediate technical success was achieved in 93.9%(46/49) in group 1 and in 95.1%(39/41) in group 2, with no significant difference(P = 1.0). Similarly, there was no difference in the complication rates between the groups(group 1, 4.1% and group 2, 4.9%; P = 0.62). Stent failure was observed in 10 cases in group 1(20.4%) and in 16 cases in group 2(39.0%). The patency of stent and patient survival revealed no difference between the two groups with Kaplan-Meier analysis, with a mean patency of 111 ± 17 d in group 1 and 137 ± 19 d in group 2(P = 0.91), and a mean survival of 178 ± 35 d in group 1 and 222 ± 23 d in group 2(P = 0.57). On the contrary, the number of days of hospitalization associated with first-time SEMS placement in group 1 was shorter when compared with that number in group 2(28 vs 39 d; P < 0.05). Multivariate analysis revealed that a clinical stage of Ⅳa >(P = 0.0055), chemotherapy(P = 0.0048), and no patency of the stent(P = 0.011) were independent prognostic factors associated with patient survival.CONCLUSION: Our results showed that single-step endoscopic metal stent placement was safe and effective for treating obstructive jaundice secondary to various inoperable malignancies. | Ryuichi Yamamoto Masatomo Takahashi Yasuyo Osafune Katsuya Chinen Shingo Kato Sumiko Nagoshi Koji Yakabi | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，9： | 12 |
| 5 | Clinical impact of surveillance for head and neck cancer in patients with esophageal squamous cell carcinoma显示文摘AIM To evaluate the clinical impact of surveillance for head and neck(HN) region with narrow band imaging(NBI) in patients with esophageal squamous cell carcinoma(ESCC).METHODS Since 2006, we introduced the surveillance for HN region using NBI for all patients with ESCC beforetreatment, and each follow-up. The patients with newly diagnosed stage Ⅰ to Ⅲ ESCC were enrolled and classified into two groups as follows: Group A(no surveillance for HN region); between 1992 and 2000), and Group B (surveillance for HN region with NBI; between 2006 and 2008). We comparatively evaluated the detection rate of superficial head and neck squamous cell carcinoma (HNSCC), and the serious events due to metachronous advanced HNSCC during the follow-up.RESULTS A total 561 patients(group A: 254, group B: 307) were enrolled. Synchronous superficial HNSCC was detected in 1 patient (0.3%) in group A, and in 12 (3.9%) in group B (P=0.008). During the follow up period, metachronous HNSCC were detected in 10 patients(3.9%) in group A and in 30 patients(9.8%) in group B(P = 0.008). All metachronous lesions in group B were early stage, and 26 patients underwent local resection, however, 6 of 10 patients (60%) in group A lost their laryngeal function and died with metachronous HNSCC.CONCLUSION Surveillance for the HN region by using NBI endoscopy increase the detection rate of early HNSCC in patients with ESCC, and led to decrease serious events related to advanced metachronous HNSCC. | Hiroyuki Morimoto Tomonori Yano Yusuke Yoda Yasuhiro Oono Hiroaki Ikematsu Ryuichi Hayashi Atsushi Ohtsu Kazuhiro Kaneko | 2017 | World Journal of Gastroenterology2017，23，6： | 12 |
| 6 | Synthetic Evaluation of Steady-state Power Quality Based on Combination Weighting and Principal Component Projection Method显示文摘With integration of renewable energy and use of non-linear loads in power systems,the power quality problem is increasingly attracting attention of researchers.In China,standards for individual power quality indexes are set.However,when evaluating power quality in practice,individual indexes cannot directly reflect a comprehensive level of power quality.In this paper,a comprehensive analysis of various indexes is conducted to obtain a unified parameter for describing the characteristics of power quality from an overall perspective.First,weight values of power quality indexes are calculated by combining the subjective and objective weight.Then,based on the principal components of the projection method,projection values of boundary data and data to be evaluated are obtained.Finally,using these projection values,a grade range for power quality data is located.A practical case study is presented to show the validity of the proposed method for evaluating power quality. | Jidong Wang Wenjie Pang Lipeng Wang Xipin Pang Ryuichi Yokoyama | 2017 | CSEE Journal of Power and Energy Systems2017，3，2： | 11 |
| 7 | Lentinan prolonged survival in patients with gastric cancer receiving S-1-based chemotherapy显示文摘AIM:To examine whether administration of lentinan,purifiedβ-1,3-glucan,can prolong survival in advanced gastric cancer patients receiving S-1-based chemotherapy.METHODS:Since 2004,78 patients with metastatic or recurrent gastric cancer have received S-1-based chemotherapy as first-line treatment.Survival,side effects,and the ratio of granulocytes/lymphocytes(G/L ratio)were compared between 2 groups of patients who received chemo-immunotherapy using lentinan and chemotherapy alone.RESULTS:Median overall survival was significantly longer in the former group than in the latter group[689 d(95%CI:431-2339 d)vs 565 d(95%CI:323-662 d),P=0.0406].In addition,the G/L ratio in patients who received lentinan was maintained around or below 2,which was significantly lower than that in patients who received chemotherapy alone(P<0.001).CONCLUSION:Chemo-immunotherapy with lentinan offers a significant advantage over S-1-based chemotherapy alone in terms of survival in patients with advanced gastric cancer. | Kenji Ina Ryuichi Furuta Takae Kataoka Satoshi Kayukawa Takashi Yoshida Takaya Miwa Yoshitaka Yamamura Yuuki Takeuchi | 2011 | World Journal of Clinical Oncology2011，2，10： | 10 |

| 9 | Crosstalk between angiogenesis, cytokeratin-18, and insulin resistance in the progression of non-alcoholic steatohepatitis显示文摘AIM: To elucidate the possible crosstalk between angiogenesis, cytokeratin-18 (CK-18), and insulin resistance (IR) especially in patients with non-alcoholic steatohepatitis (NASH).METHODS: Twenty-eight patients with NASH and 11 with simple fatty liver disease (FL) were enrolled in this study and underwent clinicopathological examination. The measures of angiogenesis, CK-18, and IR employed were CD34-immunopositive vessels, CK-18immunopositive cells, and homeostasis model assessment of IR (HOMA-IR), respectively. The correlations of these factors with NASH were elucidated.RESULTS: Significant development of hepatic neovascularization was observed only in NASH, whereas almost no neovascularization could be observed in FL and healthy liver. The degree of angiogenesis was almost parallel to liver fibrosis development, and both parameters were positively correlated. Similarly, CK-18expression and HOMA-R were signifi cantly increased in NASH as compared with FL and healthy liver. Furthermore, CK-18 and HOMA-IR were also positively correlated with the degree of neovascularization. CONCLUSION: These results indicate that the crosstalk between angiogenesis, CK-18, and IR may play an important role in the onset and progression of NASH. | Mitsuteru Kitade Hitoshi Yoshiji Ryuichi Noguchi Yasuhide Ikenaka Kosuke Kaji Yusaku Shirai Masaharu Yamazaki Masahito Uemura Junichi Yamao Masao Fujimoto Akira Mitoro Masahisa Toyohara Masayoshi Sawai Motoyuki Yoshida Chie Morioka Tatsuhiro Tsujimoto Hideto Kawaratani Hiroshi Fukui | 2009 | World Journal of Gastroenterology2009，15，41： | 9 |

| 11 | Serum angiotensin-converting enzyme level for evaluating significant fibrosis in chronic hepatitis B显示文摘AIM To evaluate the diagnostic performance of angiotensinconverting enzyme(ACE)on significant liver fibrosis in patients with chronic hepatitis B(CHB). METHODS In total,100 patients with CHB who underwent liver biopsy in our hospital were enrolled,and 70 patients except for 30 patients with hypertension,fatty liver or habitual alcoholic consumption were analyzed.We compared histological liver fibrosis and serum ACE levels and evaluated the predictive potential to diagnose significant liver fibrosis by comparison with several biochemical marker-based indexes such as the aspartate aminotransferase(AST)-to-platelet ratio index(APRI),the fibrosis index based on four factors(FIB-4),the Mac-2 binding protein glycosylation isomer(M2BPGi)level and the number of platelets(Plt). RESULTS Serum ACE levels showed moderately positive correlation with liver fibrotic stages(R2=0.181).Patients with significant,advanced fibrosis and cirrhosis(F2-4)had significantly higher serum ACE levels than those with early-stage fibrosis and cirrhosis(F0-1).For significant fibrosis(≥F2),the 12.8 U/L cut-off value of ACE showed 91.7%sensitivity and 75.0%specificity.The receiver-operating characteristic(ROC)curves analysis revealed that the area under the curve(AUC)value of ACE was 0.871,which was higher than that of APRI,FIB-4,M2BPGi and Plt. CONCLUSION The serum ACE level could be a novel noninvasive,easy,accurate,and inexpensive marker of significant fibrosis stage in patients with CHB. | Ryuichi Noguchi Kosuke Kaji Tadashi Namisaki Kei Moriya Mitsuteru Kitade Kosuke Takeda Hideto Kawaratani Yasushi Okura Yosuke Aihara Masanori Furukawa Akira Mitoro Hitoshi Yoshiji | 2017 | World Journal of Gastroenterology2017，23，36： | 6 |

| 13 | GIS-based Frequency Ratio and Logistic Regression Modelling for Landslide Susceptibility Mapping of Debre Sina Area in Central Ethiopia显示文摘Ethiopia has a mountainous landscape which can be divided into the Northwestern and Southeastern plateaus by the Main Ethiopian Rift and Afar Depression. Debre Sina area is located in Central Ethiopia along the escarpment where landslide problem is frequent due to steep slope, complex geology, rift tectonics, heavy rainfall and seismicity. In order to tackle this problem, preparing a landslide susceptibility map is very important. For this, GISbased frequency ratio(FR) and logistic regression(LR) models have been applied using landslide inventory and the nine landslide factors(i.e. lithology, land use, distance from river & fault, slope, aspect, elevation, curvature and annual rainfall). Database construction, weighting each factor classes or factors, preparing susceptibility map and validation were the major steps to be undertaken. Both models require a rasterized landslide inventory and landslide factor maps. The former was classified into training and validation landslides. Using FR model, weights for each factor classes were calculated and assigned so that all the weighted factor maps can be added to produce a landslide susceptibility map. In the case of LR model, the entire study area is firstly divided into landslide and non-landslide areas using the training landslides. Then, these areas are changed into landslide and non-landslide points so as to extract the FR maps of the nine landslide factors. Then a linear relationship is established between training landslides and landslide factors in SPSS. Based on this relationship, the final landslide susceptibility map is prepared using LR equation. The success-rate and prediction-rate of FR model were 74.8% and 73.5%, while in case of LR model these were 75.7% and 74.5% respectively. A close similarity in the prediction and validation rates showed that the model is acceptable. Accuracy of LR model is slightly better in predicting the landslide susceptibility of the area compared to FR model. | Matebie METEN Netra Prakash BHANDARY Ryuichi YATABE | 2015 | Journal of Mountain Science2015，12，6： | 6 |
| 14 | A hybrid multi-objective optimization method considering optimization problems in power distribution systems显示文摘Various kinds of new engineering technologies have been studied to realize the low-carbon and sustainable power supply systems all over the world.In actual implementation of these technologies,mostly,there are multiple objectives with trade off relationships among each other,and also various constraints in the achievement of these objectives.Therefore,it should be essential to solve multiobjective optimization problems effectively in the applications of these new technologies in power systems.This paper proposes an improved method to realize multiobjective optimization for critical challenges in advanced power systems.To realize that,in an optimal dispersed generation installation problem,that is,one of effective measures for low-carbon power systems,various optimization methods and their combination methods are evaluated and a hybrid method for evolutionary algorithms was developed.The method can provide improved results compared with other state-of-the-art multi-objective optimization methods. | Ken KURODA Hideki MAGORI Tomiyasu ICHIMURA Ryuichi YOKOYAMA | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，1： | 5 |
| 15 | Combined treatment of vitamin K_2 and angiotensin-converting enzyme inhibitor ameliorates hepatic dysplastic nodule in a patient with liver cirrhosis显示文摘Although it is well known that the hepatocellular carcinoma (HCC) is an ominous complication in patients with liver cirrhosis, there has been no approved drug to prevent the development of HCC to date. We previously reported that the combined treatment of vitamin K2 (VK) and angiotensin-converting enzyme inhibitor (ACE-I) significantly suppressed the experimental hepatocarcinogenesis. A 66-year-old Japanese woman with hepatitis C virus (HCV)-related liver cirrhosis developed a dysplastic nodule in the liver detected by enhanced computed tomography along with elevation of the tumor markers, namely, alpha-fetoprotein (AFP) and lectin-reactive demarcation (AFP-L3), suggesting the presence of latent HCC. After oral administration of VK and ACE-I, the serum levels of both AFP and AFP-L3 gradually decreased without any marked alteration of the serum aminotransferase activity. After one-year treatment, not only the serum levels of AFP and AFP-L3 returned to the normal ranges, but also the dysplastic nodule disappeared. Since both VK and ACE-I are widely used without serious side effects, this combined regimen may become a new strategy for chemoprevention against HCC. | Hitoshi Yoshiji Ryuichi Noguchi Masaharu Yamazaki Yasuhide Ikenaka Masayoshi Sawai Masatoshi Ishikawa Hideto Kawaratani Tsuyoshi Mashitani Mitsuteru Kitade Kosuke Kaji Masahito Uemura Junichi Yamao Masao Fujimoto Akira Mitoro Masahisa Toyohara Motoyuki Yoshida Hiroshi Fukui | 2007 | World Journal of Gastroenterology2007，13，23： | 5 |
| 16 | Evaluation of endoscopic biliary stenting for obstructive jaundice caused by hepatocellular carcinoma显示文摘AIM:To review the usefulness of endoscopic biliary stenting for obstructive jaundice caused by hepatocellular carcinoma and identify problems that may need to be addressed.METHODS:The study population consisted of 36 patients with obstructive jaundice caused by hepatocellular carcinoma(HCC)who underwent endoscopic biliary stenting(EBS)as the initial drainage procedure at our hospital.The EBS technical success rate and drainage success rate were assessed.Drainage was considered effective when the serum total bilirubin level decreased by 50%or more following the procedure compared to the pre-drainage value.Survival time after the procedure and patient background characteristics were assessed comparatively between the successful drainage group(group A)and the non-successful drainage group(group B).The EBS stent patency duration in the successful drainage group(group A)was also assessed.RESULTS:The technical success rate was 100%for both the initial endoscopic nasobiliary drainage and EBS in all patients.Single stenting was placed in 21 patients and multiple stenting in the remaining 15 patients.The drainage successful rate was 75%and the median interval to successful drainage was 40 d(2-295 d).The median survival time was 150 d in group A and 22 d in group B,with the difference between the two groups being statistically significant(P<0.0001).There were no statistically significant differences between the two groups with respect to patient background characteristics,background liver condition,or tumor factors;on the other hand,the two groups showed statistically significant differences in patients without a history of hepatectomy(P=0.009)and those that received multiple stenting(P=0.036).The median duration of stent patency was 43 d in group A(2-757 d).No early complications related to the EBS technique were encountered.Late complications occurred in 13 patients(36.1%),including stent occlusion in 7,infection in 3,and distal migration in 3.CONCLUSION:EBS is recommended as the initial drainage procedure for obstructive jaundice caused by HCC,as it appears to contribute to prolongation of survival time. | Gen Sugiyama Yoshinobu Okabe Yusuke Ishida Fumihiko Saitou Ryuichi Kawahara Hiroto Ishikawa Hiroyuki Horiuchi Hisafumi Kinoshita Osamu Tsuruta Michio Sata | 2014 | World Journal of Gastroenterology2014，20，22： | 4 |
| 17 | 发电不确定性条件下电动汽车对智能家居能量管理的贡献(英文)显示文摘光伏、风电等可再生能源的大规模接入给电力系统的运行带来了诸多问题,如由发电过剩引起的电网反向潮流、电网频率和节点电压调节容量的不足。作为解决可再生能源出力波动性引起的不确定性问题的方法之一,采用电动汽车作为储能装置,即所谓的V2H(vehicle to house)或者V2G(vehicle to grid),将发挥重要作用,因此有必要建立电动汽车应用评估方法。以配有光伏发电装置和一辆电动汽车的某智能家居为例,定量评估了电动汽车电池充放电对光伏发电输出功率的家庭内部使用比例、家庭用电成本和CO2排放量的影响。分析结果表明,通过光伏发电装置和电功汽车电池的有效配合使用,可以减少反向潮流和CO2排放。最后,通过仿真分析论证了多辆电动汽车对含有多栋智能家居的智能化小区能量管理的贡献。 | Ryuichi YOKOYAMA Kouichirou YOSHIMI Takahiko MASUDA Haruhiko KONDOU | 2011 | 电力系统自动化2011，35，22： | 4 |

| 19 | Double balloon enteroscopy to retrieve an accidentally swallowed dental reamer deep in the jejunum显示文摘Accidentally swallowed foreign objects are not uncommon but difficult to manage without complications. We describe the case of a 68 year old man who accidentally a swallowed sharp-pointed dental reamer that had reached deep in his jejunum. Double balloon enteroscopic retrieval was performed with polypectomy snare but the reamer was entangled in the wire loop of the snare and penetrated the jejunal wall. After releasing the reamer by pushing and pulling the snare for approximately 30 min, the reamer was retrieved with biopsy forceps. This is the first report of double balloon enteroscopic removal of a dental reamer. Furthermore, this is a novel case with regard to decision making in situations when sharp objects are swallowed. | Shingo Kato Kazuhito Kani Hidehiko Takabayashi Ryuichi Yamamoto Koji Yakabi | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，4： | 4 |
| 20 | Case of pediatric traditional serrated adenoma resected via endoscopic submucosal dissection显示文摘Traditional serrated adenoma(TSA)is a type of serrated polyp of the colorectum and is thought to be a precancerous lesion.There are three types of serrated polyps,namely,hyperplastic polyps,sessile serrated adenomas/polyps,and TSAs.TSA is the least common of the three types and accounts for about 5% of serrated polyps.Here we report a pediatric case of TSA that was successfully resected by endoscopic submucosal dissection(ESD).This rare case report describes a pediatric patient with no family history of colonic polyp who was admitted to our hospital with hematochezia.On colonoscopy,we found a polypoid lesion measuring 10 mm in diameter in the lower rectum.We selected ESD as a surgical option for en bloc resection,and histopathological examination revealed TSA.The findings in this case suggest that TSA with precancerous potential can occur in children,and that ESD is useful for treating this lesion. | Sonoko Kondo Hirohito Mori Noriko Nishiyama Takeo Kondo Ryuichi Shimono Hitoshi Okada Takashi Kusaka | 2017 | World Journal of Gastroenterology2017，23，24： | 4 |
