Randomized Controlled Trial
Goal-Directed Fluid Therapy Using Stroke Volume Variation for Resuscitation after Low Central Venous Pressure-Assisted Liver Resection: A Randomized Clinical Trial.
The optimal perioperative fluid resuscitation strategy for liver resections remains undefined. Goal-directed therapy (GDT) embodies a number of physiologic strategies to achieve an ideal fluid balance and avoid the consequences of over- or under-resuscitation. ⋯ Stroke volume variation-guided GDT is safe in patients undergoing liver resection and led to less intraoperative fluid. Although the incidence of postoperative complications was similar in both arms, lower intraoperative resuscitation volume was independently associated with decreased postoperative morbidity in the entire cohort. Future studies should target extensive resections and identify patients receiving large resuscitation volumes, as this population is more likely to benefit from this technique.

Deceased-donor kidneys are often exposed to ischemic events from donor instability, as evidenced by acute kidney injury (AKI). Clinicians may be reluctant to transplant kidneys with AKI that also have prolonged cold ischemia time (CIT) for fear of an additional deleterious effect. ⋯ These results suggest that in the setting of a previous ischemic donor event, prolonged CIT has limited bearing on long-term outcomes. This may be important evidence that despite the occurrence of other ischemic events, kidneys with prolonged CIT offer acceptable outcomes to recipients and are a potential source to expand the donor pool.

Ventral hernia repairs are one of the most common procedures performed by the general surgeon. They are also among the most complex procedures performed. We hypothesized that with each surgical failure, subsequent ventral hernia repair becomes more complicated and morbid. ⋯ Previous ventral hernia repair increases the complication profile of repair, creating a vicious cycle of repair, complications, reoperation, and re-repair. Furthermore, long-term outcomes for ventral hernia repair are poor. Future studies should focus on hernia prevention and improving long-term outcomes after hernia repair.

The aim of this study was to investigate the messenger RNA and protein expressions of SET and MYND domain-containing protein 3 (SMYD3) and transforming growth factor-β1 (TGF-β1) in gastric cancer (GC) and to explore the correlations between these proteins and the biologic behavior of GC. ⋯ SET and MYND domain-containing protein 3 expression and TGF-β1 expression in GC tissues were significantly and positively correlated. High expression levels of SMYD3 and TGF-β1 can indicate poor prognoses for GC patients.

The anatomic difficulties that we have to deal with in open surgery for rectal cancer have not been overcome with the laparoscopic approach. In the search for a solution, a change of concept arose: approaching the rectum from below. The main objectives of this study were to show the potential advantages of the hybrid transabdominal-transanal total mesorectal excision (taTME). This approach may improve quality of the mesorectal specimens. Second, proctectomy can be technically easier and more safely performed "down to up," which would result in shorter surgical times, lower conversion rates, and less morbidity. ⋯ Pathologic analysis showed a very good macroscopic quality of TME specimens, which is the most important prognostic factor in rectal cancer. Intraoperative outcomes regarding conversion, surgical times, and intraoperative complications are very satisfactory. Short-term morbidity and oncologic outcomes are as good as in other laparoscopic TME series.
