The recent Southampton consensus guideline and two previous international consensus meetings held in Louisville and morioka in 2008 and 2014,respectively have recommended laparoscopic liver resection(LLR)as a standard procedure for selected patients with colorectal liver metastases(CRLM)(1-3).The Oslo-CoMet and LapOpHuva studies are the only two randomized controlled trials(RCTs)that have provided solid evidence showing that LLR is a safer,less invasive,and more cost-effective approach with higher health-related quality of life and oncological outcomes equivalent to those of open liver resection(OLR)for patients with CRLM(4-6).

AIM:To investigate whether a stapled technique is superior to the conventional hand-sewn technique for gastro/duodenojejunostomy during pylorus-preserving pancreaticoduodenectomy(PpPD).METHODS:In October 2010,we introduced a mechanical anastomotic technique of gastro-or duodenojejunostomy using staplers during *** compared clinical outcomes between 19 patients who underwent PpPD with a stapled gastro/duodenojejunostomy(stapled anastomosis group)and 19 patients who underwent PpPD with a conventional hand-sewn duodenojejunostomy(hand-sewn anastomosis group).RESULTS:The time required for reconstruction was significantly shorter in the stapled anastomosis group than in the hand-sewn anastomosis group(186.0±29.4 min vs 219.7±50.0 min,P=0.02).In addition,intraoperative blood loss was significantly less(391.0±212.0 mL vs 647.1±482.1 mL,P=0.03)and the time to oral intake was significantly shorter(5.4±1.7d vs 11.3±7.9 d,P=0.002)in the stapled anastomosis group than in the hand-sewn anastomosis *** were no differences in the incidences of delayed gastric emptying and other postoperative complications between the ***:These results suggest that stapled gastro/duodenojejunostomy shortens reconstruction time during PpPD without affecting the incidence of delayed gastric emptying.

Familial adenomatous polyposis is associated with a high incidence of malignancies in the upper gastrointestinal tract (particularly ampullary adenocarcinomas). However, few reports have described a correlation between familial adenomatous polyposis and gallbladder neoplasms. We present a case of a 60-year-old woman with familial adenomatous polyposis who presented with an elevated mass in the neck of the gallbladder (measuring 16 mm × 8 mm in diameter) and multiple small cholecystic polyps. She had undergone a total colectomy for ascending colon cancer associated with familial adenomatous polyposis 22 years previously. The patient underwent laparoscopic cholecystectomy under a preoperative diagnosis of multifocal gallbladder polyps. Pathologic examination of the resected gallbladder revealed more than 70 adenomatous lesions, a feature consistent with adenoma of the gallbladder. This case suggests a requirement for long-term surveillance of the biliary system in addition to the gastrointestinal tract in patients with familial adenomatous polyposis.

In the past few years, a new technology, biotechnology, has come into practical use internationally. It is prospective that application of biotechnology in the field of food production may lead to improved food quality and productivity.　　Modern biotechnology, through the use of recombinant DNA techniques, has been used for food production for some time now. Therefore, particular attention should be paid to the safety of foods and food additives produced by recombinant DNA techniques. For this reason, Japan set out the “Guideline for Safety Assessment of Foods and Food Additives Produced by Recombinant DNA Techniques” and “Guideline for Manufacturing Foods and Food Additives Produced by Recombinant DNA Techniques,” in 1991.

The fusion hindrance,which is also denominated by the term extra-push,is studied on mass-symmetric systems by the use of the liquid drop model with the two-center *** the idea that the fusion hindrance exists only if the liquid drop barrier(saddle point) is located at the inner side of the contact point after overcoming the outer Coulomb barrier,the reactions in which two barriers are overlapped with each other are *** is shown that there are many systems where the fusion hindrance does not exist for the atomic number of projectile or target nucleus Z 43,while for Z> 43,all of the mass-symmetric reactions are fusion-hindered.

A new complex plant for carbonization and composting of municipal wastes proposed for Gero City is introduced. The separated combustible waste and non-separated combustible waste are carbonized in two fluidized carbonization furnaces in the plant, and the coke produced is used in steelworks. The separated garbage and forest-wastes are mixed with dried septic-tank sludge to produce high quality compost for farms. This use of waste materials in the complex plant considerably lowers the amount of waste going to land-fills, and in addition, creates lower total emission of dioxins and carbon dioxide into the environment.
