Randomized Controlled TrialA pilot randomized study of the neutrophil elastase inhibitor, Sivelestat, in patients undergoing cardiac surgery.
The primary objective of this study was to determine the feasibility and safety of treatment with Sivelestat in humans to attenuate post-cardiopulmonary bypass lung injury. Twenty patients scheduled to undergo on-pump coronary artery bypass surgery were randomized to receive either 0.3 mg/kg/h intravenous Sivelestat sodium (Sivelestat group; n=10) or isotonic sodium chloride solution (placebo group, n=10), peri-operatively. Postoperative adverse events were recorded until hospital discharge. ⋯ The mean duration of the postoperative hospital stay was shorter in the Sivelestat group (19.0+/-3.4 vs. 25.6+/-9.1, P=0.04). The exploratory analysis of relative changes in lung functions showed trends toward attenuation of lung injury in the Sivelestat group in all three pulmonary parameters, though the inter-group difference could be due to chance (P>0.05). It is feasible to administer Sivelestat as a preventive measure against lung dysfunction after cardiopulmonary bypass.

Does obesity affect operative times and perioperative outcome of patients undergoing totally endoscopic coronary artery bypass surgery?
More and more patients undergoing coronary artery bypass grafting (CABG) are overweight. This patient group suffers from wound healing problems more often than normal-weight patients. Therefore, avoiding sternotomy in obese patients by using an endoscopic technique could be a promising approach. ⋯ There was no correlation between BMI (1) left internal mammary artery (LIMA) takedown-time [Spearman-rank correlation coefficient (R)=0.02; P=n.s.], (2) lipectomy and pericardiotomy-time (R=0.042, P=n.s.), (3) total operative-time (R=-0.083: P=n.s.), (4) cardiopulmonary-bypass-time (R=-0.012; P=n.s.), (5) aortic-endoocclusion-time (R=-0.055; P=n.s.), (6) mechanical-ventilation-time (R=0.001, P=n.s.), (7) length of ICU-stay (R=0.04; P=n.s.), (8) length of hospital-stay (R=-0.103; P=n.s.) or (9) occurrence of intra- and/or postoperative adverse events. In overweight, obese but also morbidly obese patients the TECAB procedure did not increase operative times or the rate of intra- or postoperative complications. This patient group, therefore, benefits from this less traumatic version of coronary surgery.

Clinical significance of pleural lavage cytology for non-small cell lung cancer: is surgical resection valid for patients with positive pleural lavage cytology?
The purpose of the present study was to retrospectively analyze the clinicopathological characteristics and clarify the validity of surgical resection for patients with positive pleural lavage cytology (PLC). Between 1993 and 2006, 563 patients who underwent complete surgical resection for primary non-small cell lung cancer and who were examined with regard to PLC were retrospectively analyzed. Forty-two patients (7.2%) showed positive PLC. ⋯ Intrathoracic recurrence was observed more frequently in patients with positive PLC. PLC was an independent prognostic factor. While positive PLC alone may not be a contraindication for surgical resection, patients who are complicated with a high CEA level preoperatively should receive special attention since no long-term survivors were observed.

Case ReportsPost-thoracotomy Horner syndrome associated with extrapleural infusion of local anesthetic.
Continuous incisional infusion of local anesthetic through an extrapleural catheter to achieve an intercostal nerve block is a safe and effective adjunct to control postoperative pain after thoracotomy. Local and systemic complications are rare. Here we present a case of an acute, reversible, post-thoracotomy Horner syndrome associated with the use of local anesthetic infusion via an intraoperatively placed extrapleural catheter.

Efficacy of emergent percutaneous cardiopulmonary support in cardiac or respiratory failure: fight or flight?
We retrospectively evaluated early outcome and conducted this study to determine the predictive factors for percutaneous cardiopulmonary support (PCPS) weaning and hospital discharge. From January 2004 to December 2006, 92 patients diagnosed as cardiac or respiratory failure underwent PCPS using the Capiox emergent bypass system (Terumo, Tokyo, Japan). The mean+/-S. ⋯ PCPS provides an acceptable survival rate and outcome in patients with cardiac or respiratory failure. Prompt application and selection of patients with a specific disease (myocarditis) provides good results. It is also effective in elderly patients, providing hospital survival similar to that for younger patients.
