| 1 | Optimal treatment for Siewert type Ⅱ and Ⅲ adenocarcinoma of the esophagogastric junction: A retrospective cohort study with long-term follow-up显示文摘AIM To determine the optimal treatment strategy for Siewert type Ⅱ and?Ⅲ?adenocarcinoma of the esophagogastric junction.METHODS We retrospectively reviewed the medical records of 83 patients with Siewert type?Ⅱ?and?Ⅲ?adenocarcinoma of the esophagogastric junction and calculated both an index of estimated benefit from lymph node dissection for each lymph node(LN) station and a lymph node ratio(LNR: ratio of number of positive lymph nodes to the total number of dissected lymph nodes). We used Cox proportional hazard models to clarify independent poor prognostic factors. The median duration of observation was 73 mo.RESULTS Indices of estimated benefit from LN dissection were as follows, in descending order: lymph nodes(LN) along the lesser curvature, 26.5; right paracardial LN, 22.8; left paracardial LN, 11.6; LN along the left gastric artery, 10.6. The 5-year overall survival(OS) rate was 58%. Cox regression analysis revealed that vigorous venous invasion(v2, v3)(HR = 5.99; 95%CI: 1.71-24.90) and LNR of > 0.16(HR = 4.29, 95%CI: 1.79-10.89) were independent poor prognostic factors for OS.CONCLUSION LN along the lesser curvature, right and left paracardial LN, and LN along the left gastric artery should be dissected in patients with Siewert type?Ⅱ?or?Ⅲ?adenoca rcinoma of the esophagogastric junction. Patients with vigorous venous invasion and LNR of > 0.16 should be treated with aggressive adjuvant chemotherapy to improve survival outcomes. | Kei Hosoda Keishi Yamashita Hiromitsu Moriya Hiroaki Mieno Masahiko Watanabe | 2017 | World Journal of Gastroenterology2017，23，15： | 19 |
| 2 | Trend in gastric cancer:35 years of surgical experience in Japan显示文摘AIM:To investigate the trend in gastric cancer surgery in the context of rapid therapeutic advancement in Japan and East Asia.METHODS:A retrospective analysis was performed on 4163 patients who underwent gastric resection for gastric cancer with histological confirmation between 1971 and 2007 at the surgical unit in Kitasato University Hospital,to determine the trend in gastric cancer requiring surgery.RESULTS:Gastric cancer requiring surgical resection increased in our hospital,but the incidence adjusted for population was constant during the observed pe-riod.Interestingly,the ratio of diffuse type/intestinal type gastric cancer was unexpectedly unchanged,and that of advanced/early gastric cancer(EGC)was,however,markedly reduced,while the actual incidence of potentially curative advanced gastric cancer tended to decrease.The incidence of EGC requiring surgery tended to increase as a whole,which is consistent with increased prevalence of endoscopic surveillance.As a result,overall survival and mortality of gastric cancer requiring gastric resection has recently markedly improved.CONCLUSION:In Japan,planned interventions may improve surgical gastric cancer mortality,but an unexpected trend of persistent existence of intestinal type cancer suggests the need for more robust medical intervention. | Keishi Yamashita Shinichi Sakuramoto Masayuki Nemoto Tomotaka Shibata Hiroaki Mieno Natsuya Katada Shiroh Kikuchi Masahiko Watanabe | 2011 | World Journal of Gastroenterology2011，17，29： | 11 |
| 3 | 为用离合器切割器的食道的小粒的房间肿瘤的内视镜的 submucosal 解剖显示文摘 Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate.The shortcomings of this method are the deficiencies of fixing the knife to the target lesion,and of compressing it.These shortcomings can lead to major complications such as perforation and bleeding.To reduce the risk of complications related to ESD,we developed a new grasping type scissors forceps (Clutch Cutter,Fujifilm,Japan) which can grasp and incise the targeted tissue using an electrosurgical current.Esophagogastroduodenoscopy on a 59-year-old Japanese man revealed a 16mm esophageal submucosal nodule with central depression.Endoscopic ultrasonography demonstrated a hypoechoic solid tumor limited to the submucosa without lymph node involvement.The histologic diagnosis of the specimen obtained by biopsy was granular cell tumor.It was safely and accurately resected without unexpected incision by ESD using the CC.No delayed hemorrhage or perforation occurred.Histological examination confirmed that the granular cell tumor was completely excised with negative resection margin.We report herein a case of esophageal granular cell tumor successfully treated by an ESD technique using the CC. | Keishi Komori Kazuya Akahoshi Yoshimasa Tanaka Yasuaki Motomura Masaru Kubokawa Soichi Itaba Terumasa Hisano Takashi Osoegawa Naotaka Nakama Risa Iwao Masafumi Oya Kazuhiko Nakamura | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，1： | 8 |
| 4 | Prognostic factors associated with mortality in patients with gastric fundal variceal bleeding显示文摘AIM To determine the prognostic factors associated with mortality in patients with gastric fundal variceal (GFV) bleeding.METHODS In total, 42 patients were endoscopically diagnosed with GFV bleeding from January 2000 to March 2014. We retrospectively reviewed the patients' medical records and assessed their history, etiology of liver cirrhosis, disease conditions, treatment options for GFV bleeding, medications administered before and after onset of GFV bleeding, blood test results(hemoglobin, albumin, and bilirubin concentrations), and imaging results(including computed tomography and abdominal ultrasonography). We also assessed the prognostic factors associated with short-term mortality(up to 90 d) and long-term mortality in all patients.RESULTS Multivariate analysis showed that prophylactic administration of antibiotics was an independent prognostic factor associated with decreases in short-term mortality (OR = 0.08, 95%CI: 0.01-0.52) and longterm mortality (OR = 0.27, 95%CI: 0.08-0.91) in patients with GFV bleeding. In contrast, concurrent hepatocellular carcinoma (HCC) and regular use of proton pump inhibitors (PPI) were independent prognostic factors associated with increases in shortterm mortality(HCC: OR = 15.4, 95%CI: 2.08-114.75; PPI: OR = 12.76, 95%CI: 2.13-76.52) and long-term mortality (HCC: OR = 7.89, 95%CI: 1.98-31.58; PPI: OR = 10.91, 95%CI: 2.86-41.65) in patients with GFV bleeding. The long-term overall survival rate was significantly lower in patients who regularly used PPI than in those who did not use PPI(P = 0.0074).CONCLUSION Administration of antibiotics is associated with decreased short- and long-term mortality, while concurrent HCC and regular PPI administration are associated with increased short- and long-term mortality. | Keishi Komori Masaru Kubokawa Eikichi Ihara Kazuya Akahoshi Kazuhiko Nakamura Kenta Motomura Akihide Masumoto | 2017 | World Journal of Gastroenterology2017，23，3： | 7 |
| 5 | The effect of exposure to normbaric hypoxia on the body weight in rats显示文摘为了确定大鼠的体重是否在标准气压缺氧环境下会减轻,本实验将12只5周龄Wis-tar大鼠移高至海拔2260m并使之持续暴露于含10%O2的低氧小低压舱内(相当于在海拔5000m)20日。在基线每5日测一次体重。由于标准气压缺氧环境可影响血循环功能,所以在大鼠移入高原前后20天,分别对其肺动脉压和血红蛋白浓度进行了测定。基线处体重为(222.4±20.7)g,而与基线处相比。大鼠体重在移高5、10、15和20天后明显下降,分别下降了(4.88±SD)%、(7.67土SD)%、(11.05±SD)%和(11.9±SD)%,差异显著(P<0.05)。基线处大鼠的平均肺动脉压为(21.3±2.5)mmHg,低氧暴露20天后肺动脉压明显增高[(45.3±5.8)mmHg,P<0.001]。血红蛋白浓度在基线处的平均值为(14.5±3.2)g/L,而在低氧暴露20天后明显增加[(22.6±5.4)g/L,P<0.001]。该结果显示,模拟高海拔可使大鼠体重明显下降,这与先前报道的人体试验结果相似。结果也进一步说明,标准气压下持续的低氧环境对肺动脉压和血红蛋白浓度可产生实质性影响。 | Yi Lina Keishi Kubo Ge Rili Benjamin Levine Tony Babb | 2005 | 青海医学院学报2005，26，3： | 6 |
| 6 | Segmental gastrectomy with radical lymph node dissection for early gastric cancer显示文摘AIM: To describe a new surgical technique and evaluate the early results of segmental gastrectomy (SG) with modified D2 lymph node (LN) dissection for early gastric cancer (EGC). METHODS: Fourteen patients with EGC underwent SG with modified D2 dissection from 2006 to 2008. Their operative results and postoperative courses were compared with those of 17 patients who had distal gastrectomy (DG) for EGC during the same period. RESULTS: Operating time, blood loss, and hospital stay were similar between the 2 groups. Postoperative complications developed significantly more frequently in the DG group than in the SG group. Mean number of dissected LNs per each station in the SG group was comparable with that in the DG group. Postoperative recovery of body weight was significantly better in the SG group than in the DG group. The incidence of reflux esophagitis and gastritis after surgery was less frequent in the SG group than in the DG group.CONCLUSION: SG with modified D2 LN dissection may be a new function-preserving gastrectomy that is feasible for treatment of EGC with possible LN involvement. | Takeru Matsuda Kunihiko Kaneda Manabu Takamatsu Keishi Aishin Masahide Awazu Akiko Okamoto Katsunori Kawaguchi | 2010 | World Journal of Gastroenterology2010，16，41： | 6 |
| 7 | An unusual enteropathy-associated T-cell lymphoma with MYC translocation arising in a Japanese patient:A case report显示文摘Enteropathy-associated T-cell lymphoma(EATL) is a rare peripheral T-cell lymphoma classified into 2 types,with or without celiac disease,based on histology.Type 2 EATL is less commonly associated with celiac disease,in which cells are characterized by being monomorphic and small-to medium-sized.Cells are characterized by CD8 and CD56 expression and c-MYC oncogene locus gain.We present an atypical case of type 2 EATL in the jejunum,with human T-lymphotropic virus-1 that was CD4-CD8+ CD56-CD30-CD25-TIA-1+ and granzyme B+ on immunohistological staining.It also displayed translocation of chromosome 8p24(c-MYC),as determined by fluorescent in situ hybridization.Mucosal spreading and intraepithelial invasion by lymphoma with villous atrophy were detected adjacent to the mucosal layer.The lymphoma may be derived from intraepithelial CD8+ T cells,similar to celiac disease. | Kenji Okumura Masahiko Ikebe Tatsuro Shimokama Morishige Takeshita Nao Kinjo Keishi Sugimachi Hidefumi Higashi | 2012 | World Journal of Gastroenterology2012，18，19： | 3 |

| 10 | Macroscopic appearance of TypeⅣand giant Type Ⅲ is a high risk for a poor prognosis in pathological stage Ⅱ/Ⅲ advanced gastric cancer with postoperative adjuvant chemotherapy显示文摘AIM To evaluate whether a high risk macroscopic appearance(Type Ⅳ and giant Type Ⅲ) is associated with a dismal prognosis after curative surgery, because its prognostic relevance remains elusive in pathological stage Ⅱ/Ⅲ(p Stage Ⅱ/Ⅲ) gastric cancer.METHODS One hundred and seventy-two advanced gastric cancer(defined as pT2 or beyond) patients with p Stage Ⅱ/Ⅲ who underwent curative surgery plus adjuvant S1 chemotherapy were evaluated, and the prognostic relevance of a high-risk macroscopic appearance was examined. RESULTS Advanced gastric cancers with a high-risk macroscopic appearance were retrospectively identified by preoperative recorded images. A high-risk macroscopic appearance showed a significantly worse relapse free survival(RFS)(35.7%) and overall survival(OS)(34%) than an average risk appearance(P = 0.0003 and P < 0.0001, respectively). A high-risk macroscopic appearance was significantly associated with the 13^(th) Japanese Gastric Cancer Association(JGCA) pT(P = 0.01), but not with the 13^(th) JGCA pN. On univariate analysis for RFS and OS, prognostic factors included 13^(th) JGCA p Stage(P < 0.0001)and other clinicopathological factors including macroscopic appearance. A multivariate Cox proportional hazards model for univariate prognostic factors identified highrisk macroscopic appearance(P = 0.036, HR = 2.29 for RFS and P = 0.021, HR = 2.74 for OS) as an independent prognostic indicator. CONCLUSION A high-risk macroscopic appearance was associated with a poor prognosis, and it could be a prognostic factor independent of 13^(th) JGCA stage in p Stage Ⅱ/Ⅲ advanced gastric cancer. | Keishi Yamashita Akira Ema Kei Hosoda Hiroaki Mieno Hiromitsu Moriya Natsuya Katada Masahiko Watanabe | 2017 | World Journal of Gastrointestinal Oncology2017，9，4： | 2 |
