| 1 | Short-and long-term outcomes of endoscopically treated superficial non-ampullary duodenal epithelial tumors显示文摘BACKGROUND It is widely recognized that endoscopic resection(ER) of superficial nonampullary duodenal epithelial tumors(SNADETs) is technically challenging and may carry high risks of intraoperative and delayed bleeding and perforation.These adverse events could be more critical than those occurring in other levels of the gastrointestinal tract. Because of the low prevalence of the disease and the high risks of severe adverse events, the curability including short-and long-term outcomes have not been standardized yet.AIM To investigate the curability including short-and long-term outcomes of ER for SNADETs in a large case series.METHODS This retrospective study included cases that underwent ER for SNADETs at our university hospital between March 2004 and July 2017. Short-term outcomes of ER were measured based on en bloc and R0 resection rates as well as adverse events. Long-term outcomes included local recurrence detected on endoscopic surveillance and disease-specific mortality in patients followed up for ≥ 12 mo after ER.RESULTS In the study, 131 patients with 147 SNADETs were analyzed. The 147 ERs consisted of 136 endoscopic mucosal resections(EMRs)(93%) and 11 endoscopic submucosal dissections(ESDs)(7%). The median tumor diameter was 10 mm.The pathology diagnosis was adenocarcinoma(56/147, 38%), high-grade intraepithelial neoplasia(44/147, 30%), or low-grade intraepithelial neoplasia(47/147, 32%). The R0 resection rate was 68%(93/136) in the EMR group and73%(8/11) in the ESD group, respectively. Cap-assisted EMR(known as EMR-C)showed a higher rate of R0 resection compared to the conventional method of EMR using a snare(78% vs 62%, P = 0.06). No adverse event was observed in the EMR group, whereas delayed bleeding, intraoperative perforation, and delayed perforation in 3, 3, and 5 patients occurred in the ESD group, respectively. One patient with perforation required emergency surgery. In the 43 mo median follow-up period, local recurrence was found in four EMR cases and all cases were treated endoscopically. No patient died due to tumor recurrence.CONCLUSION Our findings suggest that ER provides good long-term outcomes in the patients with SNADETs. EMR is likely to become the safe and reliable treatment for small SNADETs. | Yuko Hara Kenichi Goda Akira Dobashi Tomohiko Richard Ohya Masayuki Kato Kazuki Sumiyama Takehiro Mitsuishi Shinichi Hirooka Masahiro Ikegami Hisao Tajiri | 2019 | World Journal of Gastroenterology2019，25，6： | 9 |
| 2 | A new index for non-invasive assessment of liver fibrosis显示文摘AIM:To construct and evaluate a new non-invasive fibrosis index for assessment of the stage of liver f ibrosis. METHODS:A new f ibrosis index (Fibro-Stiffness index) was developed in 165 of 285 patients with chronic hepatitis C, and was validated in the other 120 patients where liver biopsy was performed. Its usefulness was compared with liver stiffness (LS) measured by FibroScan, the aminotransferase-to-platelet ratio index, the Forns index and the FibroIndex. RESULTS: The Fibro-Stiffness index consists of LS,platelet count and prothrombin time. The values of the Fibro-Stiffness index differed signif icantly between neighboring f ibrosis stages except F0-F1. The area under the receiver operating characteristics curves of the Fibro-Stiffness index for prediction of F≥2 (0.90), F≥ 3 (0.90) and F= 4(0.92) in the estimation group and those for F≥ 3 (0.93) and F =4 (0.97) in the validation group were the highest among the 5 methods examined. The accuracy of the Fibro-Stiffness index had highest values for F≥2, F≥3 and F=4 in both the estimation and validation groups. The diagnostic performance for F= 4 was improved by a combination of the Fibro-Stiffness index with serum hyaluronic acid level. CONCLUSION: The Fibro-Stiffness index was constructed and validated. It showed superior diagnostic performance to other indices for F ≥ 2,3 and 4. | Naohiro Ichino Keisuke Osakabe Toru Nishikawa Hiroko Sugiyama Miho Kato Shiho Kitahara Senju Hashimoto Naoto Kawabe Masao Harata Yoshifumi Nitta Michihito Murao Takuji Nakano Yuko Arima Hiroaki Shimazaki Koji Suzuki Kentaro Yoshioka | 2010 | World Journal of Gastroenterology2010，16，38： | 7 |
| 3 | Exenatide improves hepatic steatosis by enhancing lipid use in adipose tissue in nondiabetic rats显示文摘AIM:To investigate the metabolic changes in skeletal muscle and/or adipose tissue in glucagon-like peptide-1-induced improvement of nonalcoholic fatty liver disease(NAFLD).METHODS:Male Wistar rats were fed either a control diet(control group)or a high-fat diet(HFD).After 4wk,the HFD-fed rats were subdivided into two groups;one group was injected with exenatide[HFD-Ex(+)group]and the other with saline[HFD-Ex(-)group]every day for 12 wk.The control group received saline and were fed a control diet.Changes in weight gain,energy intake,and oxygen consumption were analyzed.Glucose tolerance tests were performed after 8 wk of treatment.Histological assessments were performed in liver and adipose tissue.RNA expression levels of lipid metabolism related genes were evaluated in liver,skeletal muscle,and adipose tissue.RESULTS:Exenatide attenuated weight gain[HFDEx(-)vs HFD-Ex(+)]and reduced energy intake,which was accompanied by an increase in oxygen consumption and a decrease in the respiratory exchange ratio[HFD-Ex(-)vs HFD-Ex(+)].However,exenatide did not affect glucose tolerance.Exenatide reduced lipid content in the liver and adipose tissue.Exenatide did not affect the expression of lipid metabolism-related genes in the liver or skeletal muscle.In adipose tissue,exenatide significantly upregulated lipolytic genes,including hormone-sensitive lipase,carnitine palmitoyltransferase-1,long-chain acyl-CoA dehydrogenase,and acyl-CoA oxidase 1[HFD-Ex(-)vs HFD-Ex(+)].Exenatide also upregulated catalase and superoxide dismutase 2[HFD-Ex(-)vs HFD-Ex(+)].CONCLUSION:In addition to reducing appetite,enhanced lipid use by exenatide in adipose tissue may reduce hepatic lipid content in NAFLD,most likely by decreasing lipid influx into the liver. | Kosuke Tanaka Yuko Masaki Masatake Tanaka Masayuki Miyazaki Munechika Enjoji Makoto Nakamuta Masaki Kato Masatoshi Nomura Toyoshi Inoguchi Kazuhiro Kotoh Ryoichi Takayanagi | 2014 | World Journal of Gastroenterology2014，20，10： | 6 |
| 4 | Distribution of HBV genotypes among HBV carriers in Benin:phylogenetic analysis and virological characteristics of HBV genotype E显示文摘AIM: To determine the distribution of Hepatitis B virus (HBV) genotypes in Benin, and to clarify the virological characteristics of the dominant genotype.METHODS: Among 500 blood donors in Benin, 21 HBsAg-positive donors were enrolled in the study. HBV genotypes were determined by enzyme immunoassay and restriction fragment length polymorphism. Complete genome sequences were determined by PCR and direct sequencing.RESULTS: HBV genotype E (HBV/E) was detected in 20/21 (95.2%), and HBV/A in 1/21 (4.8%). From the age-specific prevalence of HBeAg to anti-HBe seroconversion (SC) in 19 HBV/E subjects, SC was estimated to occur frequently in late teens in HBV/E.The comparison of four complete HBV/E genomes from HBeAg-positive subjects in this study and five HBV/E sequences recruited from the database revealed that HBV/E was distributed throughout West Africa with very low genetic divers ity (nucleotide homology 96.7-99.2%).Based on the sequences in the basic core promoter (BCP)to precore region of the nine HBV/E isolates compared to those of the other genotypes, a nucleotide substitution in the BCP, G1757A, was observed in HBV/E.CONCLUSION: HBV/E is predominant in the Republic of Benin, and SC is estimated to occur in late teens in HBV/E. The specific nucleotide substitution G1757A in BCP, which might influence the virological characteristics,is observed in HBV/E. | Kei Fujiwara Yasuhito Tanaka Etsuro Orito Tomoyoshi Ohno Takanobu Kato Kanji Sugihara Izumi Hasegawa Mayumi Sakurai Kiyoaki Ito Atsushi Ozasa Yuko Sakamoto Isao Arita Ahmed El-Gohary Agossou Benoit Sophie I Ogoundele-Akplogan Namiko Yoshihara Ryuzo Ueda Masashi Mizokami | 2005 | World Journal of Gastroenterology2005，11，41： | 3 |
| 5 | Endoscopic removal of foreign bodies:A retrospective study in Japan显示文摘BACKGROUND The ingestion of foreign bodies(FBs)and food bolus impaction(FBI)in the digestive tract are commonly encountered clinical problems.Methods to handle such problems continue to evolve offering advantages,such as the avoidance of surgery,reduced cost,improved visualization,reduced morbidity,and high removal success rate.However,to date,no studies have evaluated the endoscopic management of FBs in Japan.AIM To elucidate level of safety and efficacy in the endoscopic management of FBs and FBI.METHODS A total of 215 procedures were performed at Keio University Hospital between November 2007 and August 2018.Data were collected from medical charts,and endoscopic details were collected from an endoscopic reporting system.Procedures performed with a flexible gastrointestinal endoscope were only taken into account.Patients who underwent a technique involving FB or FBI from the digestive tract were only included.Data on patient sex,patient age,outpatient,inpatient,FB type,FB location,procedure time,procedure type,removal device type,success,and technical complications were reviewed and analyzed retrospectively.RESULTS Among the 215 procedures,136(63.3%)were performed in old adults(≥60 years),180(83.7%)procedures were performed in outpatients.The most common type of FBs were press-through-pack(PTP)medications[72(33.5%)cases],FBI[47(21.9%)],Anisakis parasite(AP)[41(19.1%)cases].Most FBs were located in the esophagus[130(60.5%)cases]followed by the stomach[68(31.6%)cases].AP was commonly found in the stomach[39(57.4%)cases],and it was removed using biopsy forceps in 97.5%of the cases.The most common FBs according to anatomical location were PTP medications(40%)and dental prostheses(DP)(40%)in the laryngopharynx,PTP(48.5%)in the esophagus,AP(57.4%)in the stomach,DP(37.5%)in the small intestine and video capsule endoscopy device(75%)in the colon.A transparent cap with grasping forceps was the most commonly used device[82(38.1%)cases].The success rate of the procedure was 100%,and complication were observed in only one case(0.5%).CONCLUSION Endoscopic management of FBs and FBI in our Hospital is extremely safe and effective. | Kenji JL Limpias Kamiya Naoki Hosoe Kaoru Takabayashi Yukie Hayashi Xi Sun Ryoichi Miyanaga Kayoko Fukuhara Seiichiro Fukuhara Makoto Naganuma Atsushi Nakayama Motohiko Kato Tadateru Maehata Rieko Nakamura Koichi Ueno Junichi Sasaki Yuko Kitagawa Naohisa Yahagi Haruhiko Ogata Takanori Kanai | 2020 | World Journal of Gastrointestinal Endoscopy2020，12，1： | 3 |

| 7 | 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 |
