        Background: Small lung nodules incidentally detected by chest X-rays (CXR) or CT scan frequently remain indeterminate based on clinical history and uncertain imaging diagnosis, if fine needle cytology is not feasible or unyielding. VTS resection and biopsy is near 100% accurate in establishing the diagnosis. Nevertheless, the management of small (≤1.5 cm) and very small (<0.7 cm) indeterminate and asymptomatic lung nodules remains controversial. The numerous debated. issues include: 1) the technique to identify intraoperatively the nodule undergoing VTS resection; 2) the risk or the nodule being malignant, related to its size.
