1Total pancreatectomy: Short- and long-term outcomes at a high-volume pancreas center显示文摘AIM To identify the current indications and outcomes of total pancreatectomy at a high-volume center. METHODS A single institutional retrospective study of patients undergoing total pancreatectomy from 1995 to 2014 was performed.RESULTS One hundred and three patients underwent totalpancreatectomy for indications including: Pancreatic ductal adenocarcinoma(n = 42, 40.8%), intraductal papillary mucinous neoplasms(n = 40, 38.8%), chronic pancreatitis(n = 8, 7.8%), pancreatic neuroendocrine tumors(n = 7, 6.8%), and miscellaneous(n = 6, 5.8%). The mean age was 66.2 years, and 59(57.3%) were female. Twenty-four patients(23.3%) underwent a laparoscopic total pancreatectomy. Splenic preservation and portal vein resection and reconstruction were performed in 24(23.3%) and 18 patients(17.5%), respectively. The 90 d major complications, readmission, and mortality rates were 32%, 17.5%, and 6.8% respectively. The 1-, 3-, 5-, and 7-year survival for patients with benign indications were 84%, 82%, 79.5%, and 75.9%, and for malignant indications were 64%, 40.4%, 34.7% and 30.9%, respectively.CONCLUSION Total pancreatectomy, including laparoscopic total pancreatectomy, appears to be an appropriate option for selected patients when treated at a high-volume pancreatic center and through a multispecialty approach.Hazem M Zakaria John A Stauffer Massimo Raimondo Timothy A Woodward Michael B Wallace Horacio J Asbun 2016World Journal of Gastrointestinal Surgery2016,8,9:3
2用可调式涡轮增压技术降低排放并改善扭矩特性显示文摘目前,欧洲80%的轿车柴油机已采用涡轮增压。随着排放标准的日益严格,在不久的将来,涡轮增压机型有望接近100%。目前的一个主要热点是在高速柴油机上采用可调式涡轮增压技术(VGT)。在一台1.8L直喷式柴油机上做了大量的稳态试验研究,旨在对可调式涡轮增压发动机与配置带放气阀增压器的基准发动机进行比较,以观其潜在的益处。在欧洲试验循环中对排放产物十分重视的部分负荷工况下,分别控制可调增压器的叶片位置和废气再循环(EGR)阀的位置,以优化排放指标。在不牺牲固定式增压发动机的燃油耗、烟度的前提下,在一些间断工况点测得的NO_X减少到45%。在满足最高爆发压力、烟度和涡轮前温度限制条件下,可调增压发动机与装有固定增压基准发动机相比最大扭矩提高了10%。Hawley J G Wallace F J Cox A 栾敏 董复兴 2000国外内燃机2000,,3:3
