To the Editor:Extensive liver resection represents a life-saving intervention in patients with primary or secondary liver *** advances made in the field of chemotherapy and surgical techniques have translated into a greater number of patients who are older and with more complex comorbidities presenting for major liver surgery[1]and thus having an increased risk of perioperative mortality.

BACKGROUND Given its size and location,the liver is the third most injured organ by abdominal *** to recent advances,it is unanimously accepted that the nonoperative management is the current mainstay of treatment for hemodynamically stable ***,those patients with hemodynamic instability that generally present with severe liver trauma associated with major vascular lesions will require surgical ***,an associated injury of the main bile ducts makes surgery compulsory even in the case of hemodynamic stability,thereby imposing therapeutic challenges in the tertiary referral hepato-biliopancreatic centers’*** SUMMARY We present the case of a 38-year-old male patient with The American Association for the Surgery of Trauma grade V liver injury and an associated right branch of portal vein and common bile duct avulsion,due to a crush *** patient was referred to the nearest emergency hospital and because of the hemorrhagic shock,damage control surgery was performed by means of ligation of the right portal vein branch and right hepatic artery,and hemostatic ***,the patient was referred immediately to our tertiary hepato-bilio-pancreatic *** performed depacking,a right hepatectomy and Roux-en-Y *** the 9th postoperative day,the patient developed a high output anastomotic bile leak that required a redo of the *** postoperative period was marked by a surgical incision site of incomplete evisceration that was managed non-operatively by negative wound *** follow-up was optimal,with no complications at 55 *** In conclusion,the current case clearly supports that a favorable outcome in severe liver trauma with associated vascular and biliary injuries is achieved thru proper therapeutic management,conducted in a tertiary referral hepato-bilio-pancreatic center,where a stepwise and complex surgical approach is mandatory.

以前一些飞行任务试验数据的分析表明,太阳敏感器读数异常可能是由地球反照干扰引起的。过去有一份太阳敏感器研究报告对这种效应提出了详细的数学模型。这模型既可用来研究漫反射影响,又可用来研究镜面反射影响,并且可根据受干扰的太阳敏感器测量结果、卫星位置与近似的姿态信息来提高太阳角的测量精度。根据此模型预估,漫反射光会使粗太阳敏感器(CSS)产生高达10°的误差,使精太阳敏感器(FSS)产生5″～10″测量误差,具体影响取决于卫星的轨道与姿态。只要被太阳照射的一部分地球表面出现在敏感器视场中,这些敏感器的精度就受影响。数字式太阳敏感器(DSS)对地球反照干扰的响应方式不同。多数时间里DSS的测量结果不受影响,但在一些短暂时间周期里,地球反照可能引起误差。此误差是敏感器最低有效位的许多倍,可超过1°。为了验证与改进此模型,本文把模型预估值与热带降雨量测量卫星(TRMM)的粗太阳敏感器测量值进行比较,讨论了降低与减轻地球反照影响的方法。粗太阳敏感器的误差大致与地球反照系数成比例。采用仅对紫外辐射敏感的光电池可把实际的地球反照影响减小到千分之一,可以有效地消除由地球反照干扰引起的全部误差。
