Limited resections for early stage lung cancer have been of increasing interests recently. However, it is still unclear to what extent a limited resection could preserve pulmonary function comparing to standard lobectomy, especially in the context of minimally invasive surgery. The purpose of this study was to evaluate postoperative changes of spirometry in patients undergoing video-assisted thoracic surgery (VATS) lobectomy or limited resections. ⋯ In minimal invasive surgery, wedge resection best preserves pulmonary function with similar spirometry change with VATS mediastinal procedures without lung resection. Compared with VATS lobectomy, VATS segmentectomy may help minimize loss of FVC but not FEV1 or DLCO. Pulmonary function loss per segment resected is doubled after VATS segmentectomy than after lobectomy. These results should be taken into account when deciding the extent of resection for patients with early stage lung cancer.

Thoracic surgery is currently the optimal treatment for non-small cell lung cancer (NSCLC). However, it may be responsible for numerous postoperative complications and is often used in patients with multi co morbidities. In recent years, the optimization of a patient's physical capacity before surgery has been the subject of several studies. The objective of this study was to determine whether participation in a prehabilitation program would improve outcomes after surgery and lower morbidity according to the Clavien-Dindo classification. ⋯ We have shown that prehabilitation has a positive impact on the occurrence and severity of postoperative complications after pulmonary lobectomy by minimally invasive surgery. Further studies conducted in larger populations are warranted to confirm these results.

Pulmonary adenoid cystic carcinoma (ACC) is a rare type of non-small cell lung carcinoma that may develop life-threatening severe malignant airway obstruction (SMAO). Currently, limited therapeutic approaches exist for ACC-SMAO. We investigated the efficacy and safety of para-toluenesulfonamide (PTS) intratumoral injection for ACC-SMAO. ⋯ Adverse events were reported in 75% of patients (n=6), of whom 33.3% (n=2) and 66.7% (n=4) were rated as mild and moderate, respectively. No SAE was reported. In conclusion, PTS could rapidly debulk ACC-SMAO, resulting in considerable improvement of five-year survival rate.

Veno-venous extracorporeal membrane oxygenation (VV ECMO) restores gas exchanges in severely hypoxemic patients. The need for adjunctive therapies usually originates either from refractory hypoxemia during ECMO (defined as the persistence of low blood oxygen levels despite extracorporeal support) or from the attempt to give a specific therapy for acute respiratory distress syndrome (ARDS). ⋯ The therapies currently available often allow for an effective treatment of hypoxemia during ECMO. ARDS is still lacking a specific therapy, with low-grade evidence sustaining the majority of currently used drugs.

Veno-venous extracorporeal membrane oxygenation (VV ECMO) is a rescue treatment for acute respiratory distress syndrome (ARDS) failing protective mechanical ventilation. It temporarily provides proper gas exchange: hypoxia is treated by adjusting the blood flow rate and fraction in spired oxygen over the ventilator (FiO2) on the extracorporeal membrane oxygenation (ECMO) circuit while CO2 removal is regulated by the ECMO fresh gas flow. Therefore, ventilator settings can be gradually reduced allowing the lungs to rest and recover. ⋯ Notably, in almost all papers dealing with data on VV ECMO support, the management of weaning and the weaning procedure itself are not described. The aim of this paper is to make a picture of VV ECMO weaning, as it is performed in three European large volume intensive care units (ICUs) which represent referral centers for VV ECMO treatment. We focused on data concerning the timing of VV ECMO weaning and parameters at the time of weaning, in order to assess adequacy and safety of VV ECMO removal.
