| 1 | Management of hepatitis B virus infection during treatment for hepatitis B virus-related hepatocellular carcinoma显示文摘Although liver resection is considered the most effective treatment for hepatocellular carcinoma(HCC), treatment outcomes are unsatisfactory because of the high rate of HCC recurrence. Since we reported hepatitis B e-antigen positivity and high serum hepatitis B virus(HBV) DNA concentrations are strong risk factors for HCC recurrence after curative resection of HBV-related HCC in the early 2000 s, many investigators have demonstrated the effects of viral status on HCC recurrence and post-treatment outcomes. These findings suggest controlling viral status is important to prevent HCC recurrence and improve survival after curative treatment for HBV-related HCC. Antiviral therapy after curative treatment aims to improve prognosis by preventing HCC recurrence and maintaining liver function. Therapy with interferon and nucleos(t)ide analogs may be useful for preventing HCC recurrence and improving overall survival in patients who have undergone curative resection for HBV-related HCC. In addition, reactivation of viral replication can occur after liver resection for HBV-related HCC. Antiviral therapy can be recommended for patients to prevent HBV reactivation. Nevertheless, further studies are required to establish treatment guidelines for patients with HBVrelated HCC. | Shoji Kubo Shigekazu Takemura Shogo Tanaka Hiroji Shinkawa Takayoshi Nishioka Akinori Nozawa Masahiko Kinoshita Genya Hamano Tokuji Ito Yorihisa Urata | 2015 | World Journal of Gastroenterology2015，21，27： | 19 |
| 2 | Laparoscopic hemicolectomy in a patient with situs inversustotalis显示文摘As among persons with normal anatomy, occasional patients with situs inversus develop malignant tumors. Recently, several laparoscopic operations have been reported in patients with situs inversus. We describe laparoscopic hemicolectomy with radical lymphadenectomy in such a patient. Careful consideration of the mirror-image anatomy permitted safe operation using techniques not otherwise differing from those in ordinary cases. Thus, curative laparoscopic surgery for colon cancer in the presence of situs inversus is feasible and safe. | Yushi Fujiwara Yosuke Fukunaga Masayuki Higashino Shinya Tanimura Masashi Takemura Yoshinori Tanaka Harushi Osugi | 2007 | World Journal of Gastroenterology2007，13，37： | 6 |
| 3 | Role of surgical resection for non-colorectal non-neuroendocrine liver metastases显示文摘It is widely accepted that the indications for hepatectomy in colorectal cancer liver metastases and liver metastases of neuro-endocrine tumors result in relatively better prognoses, whereas, the indications and prognoses of hepatectomy for non-colorectal non-neuroendocrine liver metastases(NCNNLM) remain controversial owing to the limited number of cases and the heterogeneity of the primary diseases. There have been many publications on NCNNLM; however, its background heterogeneity makes it difficult to reach a specific conclusion. This heterogeneous disease group should be discussed in the order from its general to specific aspect. The present review paper describes the general prognosis and risk factors associated with NCNNLM while specifically focusing on the liver metastases of each primary disease. A multidisciplinary approach that takes into consideration appropriate timing for hepatectomy combined with chemotherapy may prolong survival and/or contribute to the improvement of the quality of life while giving respite from systemic chemotherapy. | Nobuyuki Takemura Akio Saiura | 2017 | World Journal of Hepatology2017，9，5： | 6 |
| 4 | Recent traction methods for endoscopic submucosal dissection显示文摘Endoscopic mucosal resection(EMR) is problematic with regard to en bloc and curable resection rates.Advancements in endoscopic techniques have enabled novel endoscopic approaches such as endoscopic submucosal dissection(ESD), which has overcome some EMR problems, and has become the standard treatment for gastrointestinal tumors. However, ESD is technically difficult. Procedure time is longer and complications such as intraoperative perforation and bleeding occur more frequently than in EMR. Recently various traction methods have been introduced to facilitate ESD procedures, such as clip with line, external forceps, clip and snare, internal traction, double scope, and magnetic anchor. Each method must be used appropriately according to the anatomical characteristics. In this review we discuss recently proposed traction methods for ESD based on the characteristics of various anatomical sites. | Kunihiro Tsuji Naohiro Yoshida Hiroyoshi Nakanishi Kenichi Takemura Shinya Yamada Hisashi Doyama | 2016 | World Journal of Gastroenterology2016，22，26： | 6 |

| 6 | Surgery for gastric cancer patients of age 85 and older: Multicenter survey显示文摘AIM To investigate the surgical therapies for gastric cancer(GC) patients of age 85 or older in a multicenter survey.METHODS Therapeutic opportunities for elderly GC patients have expanded in conjunction with extended life expectancy. However, the number of cases encountered in a single institution is usually very small and surgical therapies for elderly GC patients have not yet been standardized completely. In the present study, a total of 134 GC patients of age 85 or older who underwent surgery in 9 related facilities were retrospectively investigated. The relationships between surgical therapies and clinicopathological or prognostic features were analyzed.RESULTS Eighty-nine of the patients(66%) presented with a comorbidity, and 26(19% overall) presented with more than two comorbidities. Radical lymphadenectomy was performed in 59 patients(44%), and no patient received pre- or post-operative chemotherapy. Forty of the patients(30%) experienced perioperative complications, but no surgical or perioperative mortality occurred. Laparoscopic surgery was performed in only 12 of the patients(9.0%). Univariate and multivariate analyses of the 113 patients who underwent R0 or R1 resection identified the factors of p T3/4 and limited lymphadenectomy as predictive of worse prognosis(HR = 4.68, P = 0.02 and HR =2.19, P = 0.05, respectively). Non-cancer-specific death was more common in c Stage Ⅰ patients than in c Stage Ⅱ or Ⅲ patients. Limited lymphadenectomy correlated with worse cancer-specific survival(P = 0.01), particularly in c Stage Ⅱ patients(P < 0.01). There were no relationships between limited lymphadenectomy and any comorbidities, except for cerebrovascular disease(P = 0.07). CONCLUSION N o n- c a n c e r- s p e c i f i c d e a t h w a s n o t n e g l i g i b l e, particularly in c Stage Ⅰ, and gastrectomy with radical lymphadenectomy appears to be an effective treatment for cS tage Ⅱ elderly GC patients. | Hirotaka Konishi Daisuke Ichikawa Hiroshi Itoh Kenichiro Fukuda Naoki Kakihara Manabu Takemura Kaori Okugawa Kiyoshi Uchiyama Masashi Nakata Hiroshi Nishi Toshiyuki Kosuga Shuhei Komatsu Kazuma Okamoto Eigo Otsuji | 2017 | World Journal of Gastroenterology2017，23，7： | 4 |

| 8 | New combination test for hepatitis C virus genotype and viral load determination using Amplicor GT HCV MONITOR test v2.0显示文摘AIM: To develop a new sensitive and inexpensive hepatitis C virus (HCV) combination test (HCV Guideline test) that enables the determination of HCV genotypes 1, 2 and 3,and simultaneous determination of HCV viral load using commercial Amplicor GT HCV MONITOR test v2.0 (microwell version).METHODS: The HCV Guideline test used the PCR product generated in commercial Amplicor GT HCV Monitor test v2.0 for viral load measurement using microwell plate version of Amplicor HCV Monitor and also captured on separate plates containing capture probes and competitive oligonucleotide probes specific for HCV genotypes 1, 2 and 3, The HCV genotype was subsequently determined using the biotin-labeled PCR product and five biotin-labeled HCV-specific probes.RESULTS: The sensitivity of the HCV Guideline test was 0.5 KIU/mL. Specificity of the HCV Guideline test was confirmed by direct sequencing of HCV core region and molecular evolutionary analyses based on a panel of 31 samples. The comparison of the HCV Guideline test and an in-house HCV core genotyping assay using 252 samples from chronic hepatitis C patients indicated concordant results for 97.2% of samples (59.5% genotype 1, 33.7% genotype 2, 6.0% genotype 3, and 0.8% mixed genotypes).Similarly, the HCV Guideline test showed concordance with a serological test, and the serological test failed to assign any serotype in 12.7% of the samples, indicating a better sensitivity of the HCV Guideline test.CONCLUSION: Clinically, both viral load and genotypes (1, 2 and 3) have been found to be major predictors of antiviral therapy outcome regarding chronic hepatitis C based on guidelines and they are, in normal circumstances,performed as separate stand-alone assays. The HCV Guideline test is a useful method for screening large cohorts in a routine clinical setting for determining the treatment regimen and for predicting the outcome of antiviral therapy of chronic hepatitis C. | Motokazu Mukaide Yasuhito Tanaka Hirokazu Kakuda Kei Fujiwara Fuat Kurbanov Eturo Orito Kentaro Yoshioka Kiyotaka Fujise Shoji Harada Takazumi Kozaki Kazuo Takemura Kazumasa Hikiji Masashi Mizokami | 2005 | World Journal of Gastroenterology2005，11，4： | 3 |

| 11 | Image quality and diagnostic performance of free-breathing diffusion-weighted imaging for hepatocellular carcinoma显示文摘AIM To retrospectively evaluate the diagnostic performance of free-breathing diffusion-weighted imaging(FB-DWI) with modified imaging parameter settings for detecting hepatocellular carcinomas(HCCs).METHODS Fifty-one patients at risk for HCC were scanned with both FB-DWI and respiratory-triggered DWI with the navigator echo respiratory-triggering technique(RTDWI).Qualitatively,the sharpness of the liver contour,the image noise and the chemical shift artifacts on each DWI with b-values of 1000 s/mm2 were independently evaluated by three radiologists using 4-point scoring.Wecompared the image quality scores of each observer between the two DWI methods,using the Wilcoxon signed-rank test.Quantitatively,we compared the signal-to-noise ratios(SNRs) of the liver parenchyma and lesion-to-nonlesion contrast-to-noise ratios(CNRs) after measuring the signal intensity on each DWI with a b-factor of 1000 s/mm2.The average SNRs and CNRs between the two DWI methods were compared by the paired t-test.The detectability of HCC on each DWI was also analyzed by three radiologists.The detectability provided by the two DWI methods was compared using Mc Nemar's test.RESULTS For all observers,the averaged image quality scores of FB-DWI were:Sharpness of the liver contour [observer(Obs)-1,3.08 ± 0.81;Obs-2,2.98 ± 0.73;Obs-3,3.54 ± 0.75],those of the distortion(Obs-1,2.94 ± 0.50;Obs-2,2.71 ± 0.70;Obs-3,3.27 ± 0.53),and the chemical shift artifacts(Obs-1,3.38 ± 0.60;Obs-2,3.15 ± 1.07;Obs-3,3.21 ± 0.85).The averaged image quality scores of RTDWI were:Sharpness of the liver contour(Obs-1,2.33 ± 0.65;Obs-2,2.37 ± 0.74;Obs-3,2.75 ± 0.81),distortion(Obs-1,2.81 ± 0.56;Obs-2,2.25 ± 0.74;Obs-3,2.96 ± 0.71),and the chemical shift artifacts(Obs-1,2.92 ± 0.59;Obs-2,2.21 ± 0.85;Obs-3,2.77 ± 1.08).All image quality scores of FB-DWI were significantly higher than those of RT-DWI(P < 0.05).The average SNR of the normal liver parenchyma by FB-DWI(11.0 ± 4.8) was not significantly different from that shown by RT-DWI(11.0 ± 5.0);nor were the lesion-to-nonlesion CNRs significantly different(FB-DWI,21.4 ± 17.7;RT-DWI,20.1 ± 15.1).For all three observers,the detectability of FB-DWI(Obs-1,43.6%;Obs-2,53.6%;and Obs-3,45.0%) was significantly higher than that of RT-DWI(Obs-1,29.1%;Obs-2,43.6%;and Obs-3,34.5%)(P < 0.05).CONCLUSION FB-DWI showed better image quality and higher detectability of HCC compared to RT-DWI,without significantly reducing the SNRs of the liver parenchyma and lesionto-nonlesion CNRs. | Yukihisa Takayama Akihiro Nishie Yoshiki Asayama Kousei Ishigami Daisuke Kakihara Yasuhiro Ushijima Nobuhiro Fujita Ken Shirabe Atsushi Takemura Hiroshi Honda | 2017 | World Journal of Hepatology2017，9，14： | 3 |
| 12 | Effectiveness of clip-and-snare method using pre-looping technique for gastric endoscopic submucosal dissection显示文摘AIM:To evaluate efficacy and safety of clip-and-snare method using pre-looping technique(CSM-PLT)for gastric endoscopic submucosal dissection(ESD).METHODS:In the CSM-PLT method,a clip attached to the lesion side was strangulated with a snare,followed by application of an appropriate tension to the lesion independent of an endoscope.Twenty consecutive lesions were resected by ESD using CSM-PLT(CSM-PLT group)and compared with a control group,including20 lesions that were resected by conventional ESD.The control group was matched based on the size and location of the lesion,presence of pathologic fibrosis,and experience of endoscopists.Total procedure time of ESD,proportion of en bloc resection,and complications were analyzed.RESULTS:The total procedure time for the CSM-PLT group was significantly shorter than that for the control group(38.5 min vs 59.5 min,P=0.023);all lesions were resected en bloc by ESD.There was no significant difference in complications between the two groups.Moreover,there was no complication in the CSM-PLT group.In one large lesion(size:74 mm)that underwentextensive CSM-PLT during ESD,we used an additional CSM-PLT on another edge of the lesion after achieving submucosal resection to the maximum extent possible during initial CSM-PLT.In two lesions,the snare came off the lesion together with the clip after a sudden pull;nevertheless,ESD was successful in all lesions.CONCLUSION:CSM-PLT was an effective and safe method for gastric ESD. | Naohiro Yoshida Hisashi Doyama Ryosuke Ota Yasuhito Takeda Hiroyoshi Nakanishi Kei Tominaga Shigetsugu Tsuji Kenichi Takemura | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，12： | 3 |

| 14 | Hepatitis B virus infection in Indonesia显示文摘Approximately 240 million people are chronically infected with hepatitis B virus(HBV),75% of whom reside in Asia. Approximately 600000 of infected patients die each year due to HBV-related diseases or hepatocellular carcinoma(HCC). The endemicity of hepatitis surface antigen in Indonesia is intermediate to high with a geographical difference. The risk of HBV infection is high in hemodialysis(HD) patients,men having sex with men,and health care workers. Occult HBV infection has been detected in various groups such as blood donors,HD patients,and HIVinfected individuals and children. The most common HBV subgenotype in Indonesia is B3 followed by C1. Various novel subgenotypes of HBV have been identified throughout Indonesia,with the novel HBV subgenotypes C6-C16 and D6 being successfully isolated. Although a number of HBV subgenotypes have been discovered in Indonesia,genotyperelated pathogenicity has not yet been elucidated in detail. Therefore,genotype-related differences in the prognosis of liver disease and their effects on treatments need to be determined. A previous study conducted in Indonesia revealed that hepatic steatosis was associated with disease progression. Pre-S2 mutations and mutations at C1638 T and T1753 V in HBV/B3 have been associated with advanced liver diseases including HCC. However,drug resistance to lamivudine,which is prominent in Indonesia,remains obscure. Although the number of studies on HBV in Indonesia has been increasing,adequate databases on HBV infection are limited. We herein provided an overview of the epidemiology and clinical characteristics of HBV infection in Indonesia. | Shoji Kubo Shigekazu Takemura Shogo Tanaka Hiroji Shinkawa Takayoshi Nishioka Akinori Nozawa Masahiko Kinoshita Genya Hamano Tokuji Ito Yorihisa Urata | 2015 | World Journal of Gastroenterology2015，21，38： | 2 |
