ReviewLung cancer resection volume: is procedure volume really an indicator of quality?
The majority of lung cancer resection studies indicate that hospital and surgeon procedure volume are inversely associated with mortality. It makes intuitive sense that performing large numbers of these procedures leads to better outcomes. ⋯ This review will examine the methodology used in the volume-outcome relationship literature and highlight important areas of concern. Careful examination of the literature demonstrates that lung cancer resection volume is not strongly associated with mortality and should not be used as a proxy measure for quality.

Thoracoscopic mediastinal lymph node dissection for lung cancer.
Mediastinal lymph node staging is an important component of the assessment and management of patients with operable non-small cell lung cancer and is necessary to achieve complete resection. During minimally invasive surgery, performance of an equivalent oncologic resection, including adequate lymph node dissection similar in extent to open thoracotomy, is absolutely necessary. ⋯ In our series, we removed about 25 lymph nodes per case in both complete VATS and R-VATS. A thorough lymph node dissection in lung cancer is possible with either VATS or R-VATS technique without oncological compromise.

Extrapleural catheters: an effective alternative for treating postoperative pain for thoracic surgical patients.
Pain control is an important aspect of video-assisted thoracoscopic surgery (VATS) procedures. Offering an effective and low-risk method of postoperative pain control is thus vital to a patient's recovery. Hotta and colleagues report the results of a clinical study comparing efficacy of epidurals vs extrapleural catheters in VATS procedures. They found that extrapleural catheters provided equivalent postoperative pain relief when compared to thoracic epidural catheters.

Multicenter StudyThe role of papillary muscle relocation in ischemic mitral valve regurgitation.
Aim of our study was to compare the results of combined approach papillary muscles relocation (PPMr) + mitral annuloplasty (MA) vs only restrictive annuloplasty (RA) in ischemic mitral regurgitation, guided by 3-dimensional (3D) echocardiography. Sixty-nine patients with severe ischemic mitral regurgitation who had PPMr + MA and coronary artery bypass grafting were matched 1:1 with patients who underwent isolated RA and coronary artery bypass grafting. A comprehensive pre- and postoperatory 2-dimensional and 3D transesophageal echocardiographic examination followed by a 3D offline assessment of the mitral valve apparatus was performed. ⋯ Recurrent mitral regurgitation equal to or greater than moderate occurred in 2 (2.8%) and 8 (11.5%) in PPMr + MA group and RA group, respectively (P < 0.02). The PPMr promoted a significant reversal in left ventricle remodeling compared with the isolated RA. PPMr + MA reduce the tenting area and the coaptation depth with respect to RA, with less incidence of recurrent mitral regurgitation.
