METHODS: Consecutive HCC patients who underwent LT were studied retrospectively and analyzed according to the use of IBS or not. Demographic and surgical data were collected from a departmental prospective maintained database. Statistical analyses were performed using the Fisher's exact test and the Wilcoxon rank sum test to examine covariate differences between patients who underwent IBS and those who did not. Univariate and multivariate Cox regression models were developed to evaluate recurrence and death,and survival probabilities were estimated using the Kaplan-Meier method and compared by the log-rank test.RESULTS: Between 2002 and 2012,158 consecutive patients who underwent LT in the same medical center and by the same surgical team were identified. Among these patients,122(77.2%) were in the IBS group and 36(22.8%) in the non-IBS group. The overall survival(OS) and recurrence free survival(RFS) at 5 years were 59.7% and 83.3%,respectively. No differences in OS(P=0.51) or RFS(P=0.953) were detected between the IBS and non-IBS groups. On multivariate analysis for OS,degree of tumor differentiation remained as the only independent predictor. Regarding patients who received IBS,no differences were detected in OS or RFS(P=0.055 and P=0.512,respectively) according to the volume infused,even when outcomes at 90 d or longer were analyzed separately(P=0.518 for both outcomes).CONCLUSION: No differences in RFS or OS were detected according to IBS use. Trials addressing this question are justified and should be designed to detect small differences in long-term outcomes.展开更多

About 25000 LTs are performed annually in the world. The potential for intraoperative bleeding is quite variable. However, massive bleeding is common and requires blood transfusion. Allogeneic blood transfusion has an immunosuppressive effect and an impact on recipient survival, in addition to the risk of transmission of viral infections and transfusion errors, among others.Techniques to prevent excessive bleeding or to use autologous blood have been proposed to minimize the negative effects of allogeneic blood transfusion.Intraoperative reinfusion of autologous blood is possible through previous selfdonation or blood collected during the operation. However, LT does not normally allow autologous transfusion by prior self-donation. Hence, using autologous blood collected intraoperatively is the most feasible option. The use of intraoperative blood salvage autotransfusion(IBSA) minimizes the perioperative use of allogeneic blood, preventing negative transfusion effects without negatively impacting other clinical outcomes. The use of IBSA in patients with cancer is still a matter of debate due to the theoretical risk of reinfusion of tumor cells. However, studies have demonstrated the safety of IBSA in several surgical procedures, including LT for hepatocellular carcinoma. Considering the literature available to date, we can state that IBSA should be routinely used in LT, both in patients with cancer and in patients with benign diseases.展开更多

那么,油田采油系统效率现状如何？是否能开发一种方案彻底解决其存在的费电问题？正是油田和商家们关注和迫切希望破解的难题。危难之际,NOBLE传出喜讯,他们研发出了NOBLE OIL WELL ENERGY SAVER（抽油机节电器）,在一定程度上克服了传统抽油机浪费电的现象。展开更多
