Does clinical T1N0 GGN really require checking for distant metastasis during initial staging for lung cancer?

Background: Accurate clinical staging is crucial for selection of optimal oncological treatment strategies in non-small cell lung cancer (NSCLC). Although brain MRI, bone scintigraphy and whole-body PET/CT play important roles in detecting distant metastases, there is a lack of evidence regarding the indication for metastatic staging in early NSCLCs, especially ground-grass nodules (GGNs). Our aim was to determine whether checking for distant metastasis is required in cases of clinical T1N0 GGN.

Proximal ligation technique prevents thrombus formation in the pulmonary vein stump after lobectomy.

Purpose: To assess the risk factors for thrombosis in the pulmonary vein stump (PVT) and the efficacy of proximal ligation in preventing PVT after lobectomy.

Methods: In total, 649 surgical patients with lung cancer were retrospectively reviewed. To compare the clinical effectiveness of PV proximal ligation, the simple stapler group (290 patients) and the proximal ligation group (359 patients who underwent thread ligation at the pericardial reflection with/without a stapler) were analyzed.

Tracheal bifurcation repair for blunt thoracic trauma in a patient with COVID-19.

Background: Tracheobronchial injury (TBI) is a rare but potentially life-threatening trauma that requires prompt diagnosis and treatment. We present a case in which a patient with COVID-19 infection was successfully treated for a TBI through surgical repair and intensive care with extracorporeal membrane oxygenation (ECMO) support.

Case Presentation: This is the case of a 31-year-old man transported to a peripheral hospital following a car crash.
