Anatomic segmentectomy is a versatile sublobar resection approach that can be both diagnostic and therapeutic in the setting of the indeterminate pulmonary nodule (IPN), metastasectomy, as well as small, peripheral cancers. We analyzed the clinical indications and perioperative outcomes after anatomic segmentectomy and explored its utility in the diagnosis and treatment of IPNs and small stage IA lung cancers. ⋯ Anatomic segmentectomy provides acceptable morbidity and mortality when approaching the IPN. Cancer is identified in 86% of lesions. Complete surgical resection can be achieved with generous parenchymal margins and thorough nodal staging for small, peripheral stage IA non-small cell lung cancer. The use of anatomic segmentectomy should be considered in this era of competing image-guided diagnostic and therapeutic approaches to peripheral lung pathology.

This study assessed whether the minute ventilation-to-carbon dioxide output (VE/VCO2) slope, a measure of ventilatory efficiency routinely measured during cardiopulmonary exercise testing (CPET), is an independent predictor of respiratory complications after major lung resections. ⋯ VE/VCO2 slope is a better predictor of respiratory complications than peak VO2. This inexpensive and operator-independent variable should be considered in the clinical practice to refine operability selection criteria.

The RIFLE (risk, injury, failure, loss, and end-stage renal disease) classification system was developed to standardize the definition of acute kidney injury (AKI) in adults. We hypothesized that AKI was associated with increased mortality and morbidity. ⋯ Acute kidney injury was independently associated with an increased occurrence of postoperative complications but not with mortality after pediatric cardiac surgery.

This investigation evaluated whether the performance at a preoperative symptom-limited stair-climbing test was a prognostic factor in resected pathologic stage I non-small cell lung cancer (NSCLC). ⋯ Preoperative cardiopulmonary fitness is a significant prognostic factor in patients after resection for early-stage NSCLC. Interventions aimed at improving exercise tolerance can be useful to improve long-term prognosis after NSCLC operations.

Chest computed tomography (CCT) is a method of screening for intrathoracic injuries in hemodynamically stable patients with penetrating thoracic trauma. The objective of this study was to examine the changes in utilization of CCT over time and evaluate its contribution to guiding therapeutic intervention. ⋯ The use of CCT for penetrating thoracic trauma increased 3.5-fold during the study period with a concurrent increase in findings of uncertain clinical significance. Patients with a normal screening CXR should be triaged with 3-hour delayed CXR, serial physical examinations, and focused assessment with sonography for trauma; and CCT should only be used selectively as a diagnostic modality.
