Randomized Controlled Trial Clinical Trial
When to remove a chest tube? A randomized study with subsequent prospective consecutive validation.
Operative procedures on the pleural space are usually managed by chest tube drainage. Timing for removing the tube is empirically established, with wide variation among surgeons. Our objective was to evaluate the effectiveness and safety of establishing a volume of 200 mL/d of uninfected drainage as a threshold for removal of chest tube, as compared with more frequently used volumes of 100 and 150 mL/d. ⋯ Increasing the threshold of daily drainage to 200 mL before removing the chest tube did not markedly affect drainage, hospitalization time, or overall costs, nor did it increase the likelihood of major pleural fluid reaccumulation. This volume (200 mL/d) could be recommended for chest tube withdrawal decision for uninfected pleural fluid with no evidence of air leaks.

Randomized Controlled Trial Clinical Trial
Assessment of basic endoscopic performance using a virtual reality simulator.
The objective of this study was to evaluate the effect of supervised training using a state-of-the-art virtual reality (VR) genitourinary endoscopy simulator on the basic endoscopic skills of novice endoscopists. ⋯ Students trained on the VR simulator demonstrated statistically significant improvement on repeat testing, but the control group showed no improvement. Endourologic training using VR simulation facilitates performance of basic endourologic tasks and might translate into better performance in the operating room.

Comparative Study
Split liver transplantation and risk to the adult recipient: analysis using matched pairs.
The technique of liver splitting is an effective way of increasing the donor pool and reducing pediatric waiting list mortality. But the procedure is still not fully accepted because of concerns that it may cause complications in adult recipients. ⋯ SLT, using the extended right hepatic lobe, does not notably differ from WLT with regard to initial graft function, postoperative complications, or patient and graft survival. Based on this, the liver can be considered a paired organ, and mandatory splitting of good-quality livers can be recommended.
