ReviewIn patients with first-episode primary spontaneous pneumothorax is video-assisted thoracoscopic surgery superior to tube thoracostomy alone in terms of time to resolution of pneumothorax and incidence of recurrence?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed whether video-assisted thoracoscopic surgery (VATS) was justifiable for first-episode primary spontaneous pneumothorax (PSP). Altogether 183 papers were found using the reported search, of which nine represented the best evidence to answer the clinical question. ⋯ Instead, secondary treatment is recommended. Lastly, two articles also examined the rate of recurrence of VATS compared to open thoracotomy (OT). The range was from 0 to 7.7% for OT vs. 10.3 to 13% for VATS, a non-statistical difference.

Randomized Controlled Trial Comparative StudyAir-leak management after upper lobectomy in patients with fused fissure and chronic obstructive pulmonary disease: a pilot trial comparing sealant and standard treatment.
A pilot trial to compare the efficacy of two different procedures to prevent postoperative air-leak in chronic obstructive pulmonary disease (COPD) patients submitted to upper lobectomy for non-small cell lung cancer. Sixty patients with COPD and lung cancer at the upper pulmonary lobes eligible for lobectomy were enrolled and randomly assigned either to standard treatment (ST) with stapling device or to electrocautery dissection and application of a collagen patch coated with human fibrinogen and thrombin (TachoSil) (experimental treatment [ET]) for the intra-operative completion of their fused fissures. ⋯ Statistically significant reduction of air-leak was registered in the ET group when overall incidence of postoperative air-leak (55% vs. 96%; P=0.03), postoperative air-leak (mean 1.63+/-1.96 vs. 4.33+/-4.12 days; P=0.0018), chest-drain (mean 3.53+/-1.59 vs. 5.90+/-3.72 days; P=0.0021) and hospital stay duration (mean 5.87+/-1.07 vs. 7.50+/-3.20 days; P=0.01) were considered. The use of TachoSil to prevent postoperative air-leak after interlobar fissure completion in patients with COPD submitted to upper lobectomy seems to be safe and more effective than the ST based on stapling device application.

Case ReportsSplenic tear causing a hemoperitoneum after cardiac surgery.
Hemoperitoneum after cardiac surgery is a very rare but life-threatening complication. We have only found a few cases described in the literature, in which the intra-abdominal hemorrhages were caused by liver bleeding, due to direct hepatic trauma or spontaneous hepatic rupture. We describe the first case of hemoperitoneum caused by a spontaneous rupture of the spleen.

Urgent segmental resection as the primary strategy in management of benign tracheal stenosis. A single center experience in 164 consecutive cases.
The report is a retrospective review of 238 benign tracheal stenoses of various etiologies treated between 1995 and 2008. To show that urgent segmental resection has complication rates similar to elective resection and, therefore, preoperative dilation is not necessary, we analysed records of patients who underwent either standard segmental resections with anterolateral mediastinal tracheal mobilization, single-suture anastomosis and neck flexion; or insertion of T-tube with oval-shaped horizontal arm. Primary segmental resection was performed in 164 patients (68.9%), including 14 cases with concomitant tracheo-esophageal fistula (TEF). ⋯ Urgent segmental resection without prior rigid bronchoscopy dilation is our strategy of choice whenever possible. As an alternative to dilation we prefer temporary insertion of modified T-tube. Stand-alone endoluminal dilation and stenting has yet to prove its safety and long-term efficacy.

The effect of diabetic medications on creatine kinase-myocardial band levels in patients undergoing coronary artery bypass surgery.
Ischemic preconditioning has been shown to attenuate the rise in creatine kinase-myocardial band levels that occur with coronary artery bypass surgery (CABG). Recently, concerns have been raised that some sulfonylureas particularly glibenclamide may block ischemic preconditioning. The purpose of this study was to determine the effect of various diabetic medicines on creatine kinase-myocardial band levels after CABG. ⋯ After univariable comparisons, linear regression was used to determine the statistically significant predictors of creatine kinase-myocardial band levels. After correction for other factors, none of the diabetic medicines was a statistically significant predictor of creatine kinase-myocardial band levels. We found that the use of glibenclamide or other diabetic medications had no effect on creatine kinase-myocardial band levels the morning after patients underwent CABG.
