| 1 | Precision surgical approach with lymph-node dissection in early gastric cancer显示文摘The gravest prognostic factor in early gastric cancer is lymph-node metastasis,with an incidence of about 10% overall. About two-thirds of early gastric cancer patients can be diagnosed as node-negative prior to treatment based on clinicpathological data. Thus, the tumor can be resected by endoscopic submucosal dissection. In the remaining third, surgical resection is necessary because of the possibility of nodal metastasis. Nevertheless, almost all patients can be cured by gastrectomy with D1+ lymph-node dissection. Laparoscopic or robotic gastrectomy has become widespread in East Asia because perioperative and oncological safety are similar to open surgery. However, after D1+ gastrectomy,functional symptoms may still result. Physicians must strive to minimize postgastrectomy symptoms and optimize long-term quality of life after this operation.Depending on the location and size of the primary lesion, preservation of the pylorus or cardia should be considered. In addition, the extent of lymph-node dissection can be individualized, and significant gastric-volume preservation can be achieved if sentinel node biopsy is used to distinguish node-negative patients.Though the surgical treatment for early gastric cancer may be less radical than in the past, the operative method itself seems to be still in transition. | Shinichi Kinami Naohiko Nakamura Yasuto Tomita Takashi Miyata Hideto Fujita Nobuhiko Ueda Takeo Kosaka | 2019 | World Journal of Gastroenterology2019，25，14： | 21 |
| 2 | Diagnostic ability of multi-detector spiral computed tomography for pathological lymph node metastasis of advanced gastric cancer显示文摘BACKGROUND The reliability of preoperative nodal diagnosis of advanced gastric cancer by multi-detector spiral computed tomography(MDCT)is still unclear.AIM To examine the diagnostic ability of MDCT more precisely by using data on intranodal pathological metastatic patterns.METHODS A total of 108 patients with advanced gastric cancer who underwent MDCT and curative gastrectomy at Kanazawa Medical University Hospital were enrolled in this study.The nodal sizes measured on computed tomography(CT)images were compared with the pathology results.A receiver-operating characteristic curve was constructed,from which the critical value(CV)was calculated by using the data of the first 69 patients retrospectively.By using the CV,sensitivity and specificity were calculated with prospectively collected data from 39 consecutive patients.This enabled a more precise one-to-one correspondence of lymph nodes between CT and pathological examination by using the size data of lymph node mapping.The intranodal pathological metastatic patterns were classified into the following four types:Small nodular,peripheral,large nodular,and diffuse.RESULTS Although all the cases were clinically suspected as having metastasis,81 had lymph node metastasis and 27 had no metastasis.The number of dissected,detected on CT,and metastatic nodes were,4241,897,and 801,respectively.The CV obtained from the receiver-operating characteristic was 7.6 mm for the long axis.The sensitivity was 91.4%and the specificity was 47.3%in the prospective phase.The large nodular and diffuse metastases were easy to diagnose becausemetastatic nodes with a large axis often exhibit these forms.CONCLUSION The ability of MDCT to contribute to a nodal diagnosis of advanced gastric cancer was examined prospectively with precise size data from node mapping,using a CV of 7.6 mm for the long axis that was calculated from the retrospectively collected data.The sensitivity was as high as 91%,and would be improved when referring to the enhanced patterns.However,its specificity was as low as 47%,because most of metastatic nodes in gastric cancer being small in size.The small nodular or peripheral type metastatic nodes were often small and considered difficult to diagnose. | Zhi-Yong Jiang Shinichi Kinami Naohiko Nakamura Takashi Miyata Hideto Fujita Hiroyuki Takamura Nobuhiko Ueda Takeo Kosaka | 2020 | World Journal of Gastrointestinal Oncology2020，12，4： | 5 |
| 3 | Surgical resection of a solitary para-aortic lymph node metastasis from hepatocellular carcinoma显示文摘Lymph node (LN) metastases from hepatocellular carcinoma (HCC) are considered uncommon. We describe the surgical resection of a solitary para-aortic LN metastasis from HCC. A 65-year-old Japanese man with B-type liver cirrhosis was admitted for the evaluation of a liver tumor. He had already undergone radiofrequency ablation, transcatheter arterial chemoembolization, and percutaneous ethanol injection therapy for HCC. Despite treatment, viable regions remained in segments 4 and 8. We performed a right paramedian sectionectomy with partial resection of the left paramedian section of the liver. Six months later, serum concentrations of alpha-fetoprotein (189 ng/mL) and PIVKA-2 (507 mAU/mL) increased. Enhanced com- puted tomography of the abdomen revealed a tumor (20 mm in diameter) on the right side of the abdominal aorta. Fluorine-18 fluorodeoxyglucose positron emission tomography revealed an increased standard uptake value. There was no evidence of recurrence in other regions. Esophagogastroduodenoscopy and colonoscopy revealed no malignant tumor in the gastrointestinal tract. Para-aortic LN metastasis from HCC was thus diagnosed. We performed lymphadenectomy. Histopathological examination revealed that the tumor was largely necrotic, with poorly differentiated HCC on its surface, which confirmed the suspected diagnosis. After 6 mo tumor marker levels were normal, with no evidence of recurrence. Our experience suggests that a solitary para-aortic LN metastasis from HCC can be treated surgically. | Junji Ueda Hiroshi Yoshida Yasuhiro Mamada Nobuhiko Taniai Sho Mineta Masato Yoshioka Youichi Kawano Tetsuya Shimizu Etsuko Hara Chiaki Kawamoto Keiko Kaneko Eiji Uchida | 2012 | World Journal of Gastroenterology2012，18，23： | 3 |
| 4 | CFD Simulation of Pulsation Noise in a Small Centrifugal Compressor with Volute and Resonance Tube显示文摘The rotational frequency tone noise emitted from the automobile turbocharger is called the pulsation noise. The cause of the pulsation noise is not fully understood, but is considered to be due to some manufacturing errors, which is called the mistuning. The effects of the mistuning of the impeller blade on the noise field inside the flow passage of the compressor are numerically investigated. Here, the flow passage includes the volute and duct located downstream of the compressor impeller. Our numerical approach is found to successfully capture the wavelength of the pulsation noise at given rotational speeds by the comparison with the experiments. One of the significant findings is that the noise field of the pulsation noise in the duct is highly one-dimensional although the flow fields are highly three-dimensional. | Daich Wakaki Yuta Sakuka Yuzo Inokuchi Kosuke Ueda Nobuhiko Yamasaki Akihiro Yamagata | 2015 | Journal of Thermal Science2015，24，1： | 2 |

| 6 | Efficacy of the fat-dissociation method for nodal harvesting in gastric cancer显示文摘BACKGROUND There is an increased need for accurate staging for gastric cancer treatment.Consequently, it is necessary to carefully examine all dissected lymph nodes for precise staging. Recently, the fat-dissociation method has been developed as a quick and accurate method for harvesting dissected lymph nodes of colorectal cancer cases.AIM To investigate the usefulness of the fat-dissociation method for harvesting dissected lymph nodes of gastric cancer cases.METHODS Fifty-six resected specimens from gastric cancer patients who underwent standard curative gastrectomy and lymph node dissection at our hospital were used. Group 2 lymph nodes were separated from each specimen, and the remaining adipose tissue containing the group 1 lymph nodes was used. Some resected specimens were subjected to the fat-dissociation method. One vial of Imofully~? was dissolved in 50 m L of saline and injected into the tissue. The tissue was incubated for 1 h and the dissolved fat was removed. Subsequently, the nodes were identified, picked up with scissors, and mapped. The number of nodes in each lymphatic compartment and duration of lymph node harvest and mapping were compared.RESULTS The fat-dissociation method was used for 24 samples, while the conventional dissection method was used for 32 samples. The total number of harvested lymph nodes was 45.9 in the fat dissociation group and 44.3 in the control group, and there was no significant difference between the two groups. There were also no significant differences in the number of lymph nodes between the two groups based on a comparison of the lymphatic compartments. However, the total median duration of the fat-dissociation method was 38.2 min, reflecting a reduced duration of approximately 60 min compared to the control group.CONCLUSION Based on our results, the fat-dissociation method is effective in shortening the duration of lymph node harvest in gastric cancer surgery. | Shinichi Kinami Toshio Ohnishi Naohiko Nakamura Zhi Yong Jiang Takashi Miyata Hideto Fujita Hiroyuki Takamura Nobuhiko Ueda Takeo Kosaka | 2020 | World Journal of Gastrointestinal Surgery2020，12，6： | 1 |
| 7 | Preoperative liver functional volumetry performed by 3D-99mTc-GSA scintigraphy/vascular fusion imaging using SYNAPSE VINCENT: a preliminary study显示文摘Aim:The present study was designed to evaluate the feasibility of preoperative liver functional volumetry performed by 3D-technetium-99m-diethylenetriaminepentaacetic acid-galactosyl-human serum albumin(99mTc-GSA)scintigraphy/vascular fusion imaging using SYNAPSE VINCENT and to examine the discrepancy between conventional and functional volumetry.Methods:The study group comprised 15 patients who underwent preoperative 3-dimensional(3D)-99mTc-GSA scintigraphy/vascular fusion imaging using SYNAPSE VINCENT software before hepatectomy between July 2014 and August 2015.The diagnosis was hepatocellular carcinoma(n=4),metastatic liver tumor(n=10),or intrahepatic cholangiocarcinoma(n=1).Right hepatectomy was performed in 2 patients,left hepatectomy in 3 patients,right posterior sectionectomy in 3 patients,segmentectomy in 2 patients,and partial hepatectomy in 4 patients.99mTc-GSA scintigraphy and computed tomography(CT)were performed to construct 3D-99mTc-GSA scintigraphy/vascular fused images.The conventional volume ratio of the planned resection region without tumor(%CT),and the functional volume ratio of the planned resection region without tumor(%GSA)were calculated.The discrepancy ratio was calculated as follows:discrepancy ratio=100-%GSA/%CT×100(%).Results:The%GSA(17.9±16.7%)was significantly lower than the%CT(21.5±17.6%)(P<0.036).In all except 2 patients,the%GSA was lower than the%CT.The discrepancy ratio ranged from-4%to 75%(median,20.7%).Conclusion:3D-99mTc-GSA scintigraphy/vascular fused images constructed using SYNAPSE VINCENT were useful for noninvasively performing functional liver volumetry in patients scheduled to undergo various patterns of hepatectomy.In planned resection regions without tumor,the functional volume ratio was about 20%lower than the conventional volume ratio. | Hiroshi Yoshida Hiroshi Makino Tadashi Yokoyama Hiroshi Maruyama Atsushi Hirakata Junji Ueda Yasuhiro Mamada Nobuhiko Taniai Eiji Uchida | 2016 | Hepatoma Research2016，2，1： | 1 |
