Background: Postoperative air leaks are the most common complication after a pulmonary resection.There is no data in the literature comparing the traditional and digital chest drainage system after a roboticassisted pulmonary lobectomy. Methods: This was a retrospective, correlational study. Medical records from 182 eligible robotic-assisted lobectomy patients were evaluated to determine the association between digital and traditional chest tube drainage systems (CTDS) with postoperative chest tube days, hospital LOS, chest tube reinsertion during hospitalization, and 30-day readmission for pneumothorax. Multiple regression was used to determine the association between CTDS while controlling for confounding variables. Results: No differences were noted between groups for age, gender, BMI, smoking, adhesions or neoadjuvant therapy. Patients with digital drainage systems had significantly shorter chest tube duration than those with traditional drainage systems (2.07 vs. 2.73 days, P=0.003). After controlling for age and BMI, CTDS was not found to be a significant predictor of CT duration. Digital drainage system were also associated with significantly shorter hospital LOS (4.02 vs. 5.06 days, P=0.01) After controlling for age, BMI, and presence of post-op a-fib, use of a digital CTDS was significantly associated with 1 day shorter hospital LOS. Chest tube reinsertion occurred four times more frequently with traditional drainage systems, but the difference did not achieve the level of statistical significance (P=0.059). The frequency of readmission due to pneumothorax was very low (1 patient per group), which prevented comparative statistical analysis. Conclusions: In the digital drainage system there are shorter chest tube days and hospital length of stay after a robotic-assisted lobectomy. The decision to remove chest tubes in the traditional drainage system is burdened with uncertainty. The digital drainage system reduces intraobserver variability allowing for improved decision making in chest tube removal. Both CT duration and hospital LOS were shorter using unadjusted analyses. Type of CTDS was not significantly associated with CT duration after controlling for age and BMI. However, after controlling for age, BMI, and post-op atrial fibrillation, use of the digital CTDS was associated with a 1 day reduction in hospital LOS.

Background Hemopericardium is a serious complication that can occur after cardiac surgery. While most post-operative causes are due to inflammation and bleeding, patients with broken sternal wires and an unstable sternum may develop hemopericardium from penetrating trauma. Case Presentation We present the case of a 62-year-old male who underwent triple coronary bypass surgery and presented five months later with sudden anterior chest wall pain. Chest computed tomography revealed hemopericardium with an associated broken sternal wire that had penetrated into the pericardial space. The patient underwent a redo-sternotomy which revealed a 3.5 cm bleeding, jagged right ventricular laceration that correlated to the imaging findings of a fractured sternal wire projecting in the pericardial space. The laceration was repaired using interrupted 4 − 0 polypropylene sutures in horizontal mattress fashion between strips of bovine pericardium. The patient’s recovery was uneventful and he was discharged on post-operative day four without complications. Conclusion Patients with broken sternal wires and an unstable sternum require careful evaluation and management as these may have potentially life-threatening complications if left untreated.

Genetic syndromes such as Brugada syndrome can lead to lethal ventricular arrhythmias. Cardiac Sympathetic Denervation has been shown to be effective in ameliorating refractory ventricular arrhythmias. We present a 33-year-old black female with a past medical history of Brugada syndrome with an implantable cardiac defibrillator (ICD), who presented with refractory ventricular tachycardia/atrial fibrillation leading to cardiogenic shock, requiring Extracorporeal membrane oxygenation (ECMO). The patient subsequently underwent bilateral stellate ganglion sympathetic denervation in the setting of refractory ventricular arrhythmias. We present this case report to showcase that thoracoscopic bilateral cardiac sympathetic denervation can be an effective definitive treatment option for ventricular arrhythmias refractory to medical management.
