Pericardial window by video-assisted thoracoscopy is an effective technique for pericardial drainage and biopsy. Apart from its diagnostic value, it allows the physician to fashion a pleuropericardial window for effective drainage while avoiding the complications of classic surgical procedures.

To evaluate the efficacy of the 3 treatment modalities (intrapleural instillation of streptokinase, video-assisted thoracoscopic surgery, thoracotomy and decortication) in the management of complicated parapneumonic effusion and empyema, a prospective study was conducted between January 2008 and June 2010. The 69 patients (52 men and 17 women, aged 18-50 years) were divided into 3 groups: 20 patients underwent intrapleural administration of streptokinase, 25 underwent video-assisted thoracoscopic surgery, and 24 had thoracotomy and decortication. Perioperative variables, mortality, and procedure success were compared among groups. In all groups, preoperative variables were well matched for age, sex, and clinical stage according to Light's classification. No allergic or hemorrhagic complication occurred. Operative time was significantly shorter in patients undergoing video-assisted thoracoscopic surgery. There was no intraoperative complication in the 2 surgically treated groups. Length of hospital stay and duration of chest drainage were significantly shorter after video-assisted thoracoscopic surgery. Procedure success was 50% after streptokinase, 92% after video-assisted thoracoscopic surgery, and 100% after thoracotomy and decortication. There was no perioperative mortality in any group. Video-assisted thoracoscopic surgery is a safe and effective treatment modality for complicated parapneumonic effusion and pleural empyema. Earlier intervention with video-assisted thoracoscopic surgery may produce better clinical results.

Repair of pectus excavatum in adult patients can be performed effectively either through an open surgical technique or thoracoscopy, with no intraoperative complications and excellent immediate results, but video-assisted thoracoscopic repair using metallic or absorbable bar stabilizers gives a better cosmetic result; however, absorbable bar stabilizers are more vulnerable and break more easily than metal stabilizers.

In chronic atrial fibrillation, prophylactic left atrial appendage exclusion is suggested to prevent occurrence of stroke, which can be achieved by a surgical or thoracoscopic approach, but a video-assisted thoracoscopic approach is effective, less invasive, and avoids the complications of a surgical approach.
