Video-assisted thoracic surgery lobectomy (VATS), open thoracotomy, and the robot for lung cancer.
Video-assisted thoracic surgery (VATS) lobectomy provides a minimally invasive approach for the management of early-stage lung cancer. Questions about the safety of VATS lobectomy and its adequacy as a cancer operation compared with open thoracotomy have hindered its universal acceptance among thoracic surgeons. Evidence suggests that VATS lobectomy can be safely performed and is an adequate cancer operation for early-stage non-small cell lung cancer. However, adequately powered well-balanced studies comparing VATS with open thoracotomy for lobectomy are lacking in the literature.

Randomized Controlled Trial
Retrograde hot-shot cardioplegia in patients with left ventricular hypertrophy undergoing aortic valve replacement.
Intermittent antegrade cold-blood cardioplegia followed by terminal warm-blood cardioplegic reperfusion or hot-shot is reported to reduce myocardial injury in the setting of coronary surgery. The efficacy of this cardioplegic technique in patients with left ventricular hypertrophy secondary to aortic stenosis remains uncertain. ⋯ The terminal retrograde hot-shot reperfusion does not add any extra benefit to antegrade cold-blood cardioplegia in preventing myocardial injury in patients with left ventricular hypertrophy undergoing aortic valve replacement. Nevertheless, it appears to reduce ischemic stress in the right ventricle. There was no difference in clinical outcome between groups.

The generation of thrombin and its procoagulant activity are upregulated during cardiopulmonary bypass (CPB). Thrombophilia associates with increased basal thrombin generation and might therefore propagate thrombin generation during CPB. The objective of this study was to test whether preoperative thrombophilic variables associate with increased generation of thrombin or its procoagulant activity during and after CPB. ⋯ Preoperative thrombophilic variables do not associate with perioperative thrombin generation or its procoagulant activity in patients undergoing CABG. Our results do not support routine thrombophilia screening before CABG.
