Review Meta AnalysisIs video-assisted thoracic surgery lobectomy better than thoracotomy for early-stage non-small-cell lung cancer? A systematic review and meta-analysis.
The study aimed to compare the reported oncological outcomes based on satisfactory lymph node dissection (LND) or lymph node sampling (LNS), systemic and loco-regional recurrence rate and long-term survival rate of patients with early-stage non-small-cell lung cancer (NSCLC) who underwent video-assisted thoracic surgery (VATS) lobectomy or thoracotomy lobectomy. A systematic review was conducted using PubMed, EMBASE and OVID-EBMR databases ranging from 1990 to 2011. The studies compared VATS and thoracotomy for patients with NSCLC, with results including LND or LNS where recurrence as well as survival rates were identified. ⋯ Systemic (RR: 0.61; 95% CI: 0.48 to 0.78; P < 0.01) and loco-regional (RR: 0.66; 95% CI: 0.46 to 0.95; P = 0.03) recurrence rates were significantly lower in the VATS group. Moreover, a significantly higher survival rate (RR: 1.09; 95% CI: 1.03 to 1.15; P < 0.01) was also demonstrated by a Forest plot in the VATS group. These results suggest that VATS lobectomy might be an eligible alternative in place of thoracotomy in patients with early-stage NSCLC by reducing recurrence and improving survival rates.

Meta AnalysisMeta-analysis of 5,674 patients treated with percutaneous coronary intervention and drug-eluting stents or coronary artery bypass graft surgery for unprotected left main coronary artery stenosis.
To compare the safety and efficacy of coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI) using drug-eluting stents (DES) in patients with unprotected left main coronary artery (ULMCA) disease. ⋯ CABG surgery remains the best option of treatment for patients with ULMCA disease, with less need of TVR and lower MACCE rates.

Review Meta AnalysisEfficacy of tranexamic acid in paediatric cardiac surgery: a systematic review and meta-analysis.
The benefit-to-risk ratio of using tranexamic acid (TXA) in paediatric cardiac surgery has not yet been determined. This systematic review evaluated studies that compared TXA to placebo in children undergoing cardiac surgery. A systematic search was conducted in all relevant randomized controlled trials. ⋯ There was marked variability in the dosage and infusion schemes used in different studies. This systematic review showed that in paediatric cardiac surgery, the benefit-to-risk ratio associated with the use of TXA cannot be adequately defined. Evidence supporting the routine use of TXA in paediatric cardiac surgery remains weak.

Meta AnalysisThe use of pre-operative brain natriuretic peptides as a predictor of adverse outcomes after cardiac surgery: a systematic review and meta-analysis.
The objective of this systematic review was to assess whether pre-operative brain natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT pro-BNP) are independent predictors of adverse outcomes after cardiac surgery. MEDLINE, Embase and the Cochrane Controlled Trials Register databases were searched. Eligible studies included observational or randomized control trials measuring natriuretic peptide concentrations before induction of anaesthesia for cardiac surgery. ⋯ The summary areas under the receiver operating characteristic curve for mortality, post-operative AF and post-operative IABP requirement were 0.61 (95% confidence interval [CI] 0.51-0.70), 0.61 (95% CI 0.58-0.64) and 0.81 (95% CI 0.73-0.89), respectively. With the limited data available, the associations between pre-operative natriuretic peptide levels and adverse outcomes after cardiac surgery were moderate. Future studies should assess whether pre-operative natriuretic peptides can provide additional independent predictive information to well-validated prognostic scores of cardiac surgery.

Meta AnalysisIntra-operative conversion is a cause of masked mortality in off-pump coronary artery bypass: a meta-analysis.
Coronary artery bypass surgery can offer excellent results when performed with cardiopulmonary bypass (on pump) or without cardiopulmonary bypass (off pump). The debate as to which technique is superior remains unanswered. Intra-operative conversion from off- to on-pump coronary surgery is a relatively unexplored phenomenon, which cannot be assessed within randomised controlled trial design. ⋯ Overall, conversion increased mortality by an odds ratio of 6.18 (95% confidence interval 4.65-8.20), whereas emergency conversion further raised the odds ratio of mortality to 6.99 (95% confidence interval 5.18-9.45). The conversion from off- to on-pump cardiac surgery may significantly increase the chance of an adverse outcome, whereas emergency conversion confers a significant rise in mortality. The risk of conversion should be discussed when obtaining the patient's informed consent and its prevention warrants serious consideration by cardiac surgeons and cardiac surgical training programmes.
