1Spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein显示文摘Preservation of the spleen at distal pancreatectomy has recently attracted considerable attention.Since our first successful trial,spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein for tumors of the pancreas and chronic pancreatitis has been performed more frequently.The technique for spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein are outlined.The splenic vein is identified behind the pancreas and within the thin connective tissue membrane.The connective tissue membrane is cut longitudinally above the splenic vein.An important issue is to remove the splenic vein from the body of the pancreas toward the spleen,since a different approach may be very difficult.The pancreas is preferably removed from the splenic artery toward the head of the pancreas itself.This procedure is much easier than removing the pancreas from the vein side.One patient had undergone distal gastrectomy for duodenal ulcer,with reconstruction by Billroth Ⅱ tehcnique.If distal pancreatectomy with splenectomy had been performed for the lesion of the distal pancreas at the time,the residual stomach would also have to be resected.The potential damage done to the patient by reconstruction of the gastrointestinal tract in combination with distal pancreatectomy and splenectomy would have been much greater than with distal pancreatectomy only with preservation of the spleen and residual stomach.Benign lesions as well as low-grade malignancy of the body and tail of the pancreas may be a possible indication for this procedure.Wataru Kimura Toshiyuki Moriya Jinfeng Ma Yukinori Kamio Toshihiro Watanabe Mitsukiro Yano Hiroto Fujimoto Koji Tezuka Ichiro Hirai Akira Fuse 2007World Journal of Gastroenterology2007,13,10:24
2Current status of function-preserving surgery for gastric cancer显示文摘Recent advances in diagnostic techniques have allowed the diagnosis of gastric cancer(GC)at an early stage.Due to the low incidence of lymph node metastasis and favorable prognosis in early GC,function-preserving surgery which improves postoperative quality of life may be possible.Pylorus-preserving gastrectomy(PPG)is one such function-preserving procedure,which is expected to offer advantages with regards to dumping syndrome,bile reflux gastritis,and the frequency of flatus,although PPG may induce delayed gastric emptying.Proximal gastrectomy(PG)is another functionpreserving procedure,which is thought to be advantageous in terms of decreased duodenogastric reflux and good food reservoir function in the remnant stomach,although the incidence of heartburn or gastric fullness associated with this procedure is high.However,these disadvantages may be overcome by the reconstruction method used.The other important problem after PG is remnant GC,which was reported to occur in approximately 5%of patients.Therefore,the reconstruction technique used with PG should facilitate postoperativeendoscopic examinations for early detection and treatment of remnant gastric carcinoma.Oncologic safety seems to be assured in both procedures,if the preoperative diagnosis is accurate.Patient selection should be carefully considered.Although many retrospective studies have demonstrated the utility of function-preserving surgery,no consensus on whether to adopt functionpreserving surgery as the standard of care has been reached.Further prospective randomized controlled trials are necessary to evaluate survival and postoperative quality of life associated with function-preserving surgery.Takuro Saito Yukinori Kurokawa Shuji Takiguchi Masaki Mori Yuichiro Doki 2014World Journal of Gastroenterology2014,20,46:17
3Usefulness of anti-ulcer drugs for the prevention and treatment of peptic ulcers induced by low doses of aspirin显示文摘AIM:To investigate the usefulness of anti-ulcer drugs for the prevention and treatment of low-dose aspirin- induced peptic ulcer. METHODS:Upper gastrointestinal endoscopy was performed in 68 patients receiving daily low-dose aspirin(81 or 100 mg/day).The endoscopic findings were classified according to the Lanza score,and the scores were compared between groups categorized according to the concomitant use of anti-ulcer drugs and the types of drugs used.In another study,31 hemorrhagic peptic ulcer patients who had been receiving low-dose aspirin were enrolled.The patients were randomly classified into the proton pump inhibitor (PPI)-treated group and the H2 receptor antagonist (H2RA)-treated group.The administration of low-dose aspirin was continued concomitantly,and endoscopic examinations were performed 8 wk later. RESULTS:The Lanza scores(mean±SD)of the gastro-mucosal lesions were 1.0±1.9 and 1.9±2.3 in 8 and 16 patients receiving prevention therapy with a PPI and an H2RA,respectively.Both scores were significantly smaller than the scores in 34 patients who were not receiving prevention therapy(4.7±1.0)and in 10 patients receiving cytoprotective anti-ulcer drugs (4.3±1.6).In the prospective study,18 and 13 patients received a PPI and an H2RA,respectively.Endoscopic examinations revealed that the tissue in the region of the gastro-mucosal lesions had reverted to normal in all patients in the PPI-treated group and in 12 patients (92%)in the H2RA-treated group;no significant differences were observed between the groups. CONCLUSION:H2RA therapy was effective for both the prevention and treatment of low-dose aspirin- induced peptic ulcer,similar to the effects of PPIs, while cytoprotective anti-ulcer drugs were ineffective in preventing ulceration.Sayaka Nakashima Shinichi Ota Shin Arai Kiyoko Yoshino Mie Inao Keiko Ishikawa Nobuaki Nakayama Yukinori Imai Sumiko Nagoshi Satoshi Mochida 2009World Journal of Gastroenterology2009,15,6:11

5Multi-temporal monitoring of wheat growth by using images from satellite and unmanned aerial vehicle显示文摘Recently near-ground remote sensing using unmanned aerial vehicles(UAV)witnessed wide applications in obtaining field information.In this research,four Rapideye satellite images and eight RGB images acquired from UAV were used from early June to the end of July,2015 covering two experimental winter wheat fields,in order to monitor wheat canopy growth status and analyze the correlation among satellite images based normalized difference vegetation index(NDVI)with UAV’s RGB images based visible-band difference vegetation index(VDVI)and ground variables of the sampled grain protein contents.Firstly,through image interpretation of UAV’s multi-temporal RGB images with fine spatial resolution,the wheat canopy color changes could be intuitively and clearly monitored.Subsequently,by monitoring the changes of satellite images based NDVI as well as VDVI values and UAV’s RGB images based VDVI values,the conclusions were made that these three vegetation indices demonstrated the same and synchronized trend of increasing at the early stage of wheat growth season,reaching up to peak values at the same timing,and starting to decrease since then.The results of the correlation analysis between NDVI of satellite images and sampled grain protein contents show that NDVI has good predicative capability for mapping grain protein content before ripening growth stage around June7,2015,while the reliability of using satellite image based NDVI to predict grain protein contents becomes worse as ripening stage approaches.The regression analysis between UAV’s RGB image based VDVI and satellite image based VDVI as well as NDVI showed good coefficients of determination.It is concluded that it is feasible and practical to temporally complement satellite remote sensing by using UAV’s RGB images based vegetation indices to monitor wheat growth status and to map within-field spatial variations of grain protein contents for small scale farmlands.Du Mengmeng Noguchi Noboru Itoh Atsushi Shibuya Yukinori 2017International Journal of Agricultural and Biological Engineering2017,10,5:3

7Coupling physics in machine learning to predict properties of high-temperatures alloys显示文摘High-temperature alloy design requires a concurrent consideration of multiple mechanisms at different length scales.We propose a workflow that couples highly relevant physics into machine learning(ML)to predict properties of complex high-temperature alloys with an example of the 9–12 wt% Cr steels yield strength.We have incorporated synthetic alloy features that capture microstructure and phase transformations into the dataset.Identified high impact features that affect yield strength of 9Cr from correlation analysis agree well with the generally accepted strengthening mechanism.Jian Peng Yukinori Yamamoto Jeffrey A.Hawk Edgar Lara-Curzio Dongwon Shin 2020npj Computational Materials2020,,1:2
8Easy fixation effects the prevention of Peterson’s hernia and Roux stasis syndrome显示文摘BACKGROUND Laparoscopic distal gastrectomy(LDG)for gastric cancer has been progressed and popular in Japan,since it was first described in 1994.Several reconstruction methods can be adopted according to remnant stomach size,and balance of pros and cons.Roux-en-Y(R-Y)reconstruction is a one of standard options after LDG.Its complications include Petersen’s hernia and Roux stasis syndrome.Here we report our ingenious attempt,fixation of Roux limb and duodenal stump,for decreasing the development of Petersen’s hernia and Roux stasis syndrome.AIM To develop a method to decrease the development of Petersen’s hernia and Roux stasis syndrome.METHODS We performed ante-colic R-Y reconstruction after LDG.After R-Y reconstruction,we fixed Roux limb onto the duodenal stump in a smooth radian.Via this small improvement in Roux limb,Roux limb was placed to the right of the ligament of Treitz.This not only changed the anatomy of the Petersen’s defect,but it also kept a fluent direction of gastrointestinal anastomosis and avoided a cross-angle after jejunojejunostomy.31 patients with gastric cancer was performed this technique after R-Y reconstruction.Clinical parameters including clinicopathologic characteristics,perioperative outcomes,postoperative complication and follow-up data were evaluated.RESULTS The operative time was(308.0±84.6 min).This improvement method took about 10 min.Two(6.5%)patients experienced pneumonia and pancreatitis,respectively.No patient required reoperation or readmission.All patients were followed up for at least 3 year,and none of the patients developed postoperative complications related to internal hernia or Roux stasis syndrome.CONCLUSION This 10 min technique is a very effective method to decrease the development of Petersen’s hernia and Roux stasis syndrome in patients who undergo LDG.Jian-Zhong Wu Hajime Orita Shun Zhang Hiroyuki Egawa Yukinori Yube Sanae Kaji Shinichi Oka Tetsu Fukunaga 2020World Journal of Gastrointestinal Surgery2020,12,8:2
