Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with lung nodules up to 3 cm in diameter located in specified bronchial segments, undergoing robotic bronchoscopy for suspected malignancy.
✕Probably not a fit
Patients with prior lung consolidation, larger lung masses, or those with specific respiratory conditions may not benefit from this study.

What this trial studies
This trial aims to determine whether a lateral decubitus strategy (LADS) is more effective than a ventilatory strategy to prevent atelectasis during robotic bronchoscopy for lung lesions. The study will compare the incidence of atelectasis, diagnostic yield, and complications associated with each strategy. It will involve adult patients undergoing bronchoscopy for lung nodules, with a focus on those located in specific bronchial segments. The trial will also assess clinical workflow improvements and diagnostic accuracy for malignancy.
Why it matters
Potential benefit: If successful, this study could enhance the safety and effectiveness of robotic bronchoscopy, leading to better diagnostic outcomes for patients with lung nodules.
How similar studies have gone: While the specific strategies being compared are novel, similar approaches in optimizing bronchoscopy techniques have shown promise in previous studies.

Show full inclusion / exclusion criteria
Inclusion Criteria: 1. Adult patients (≥ 18 years old) undergoing diagnostic robotic bronchoscopy for a lung nodule suspicious for malignancy bronchoscopy under general anesthesia. 2. Lung nodules should be up to 3 cm in diameter and located in right or left bronchial segments B2, B6, B9, and B10. Greater than 50% of the volume of the lesion needs to be below a horizontal line traced at the most anterior edge of the corresponding vertebral body. 3. Chest CT performed \< 45 days prior to bronchoscopy. 4. Voluntary informed consent to participate in the study. Exclusion Criteria: 1. Patients with prior lung consolidation, interstitial changes or lung masses (\> 3 cm in diameter) as seen on most recent CT 2. Lesions outside of the designated lung areas defined as inclusion criteria. 3. Known pregnancy 4. Vulnerable population 5. Ascites 6. Known diaphragmatic paralysis 7. Smokers or ex-smokers with known or suspected severe air-trapping defined as residual volume \> 150% of predicted 8. History of primary or secondary spontaneous pneumothorax 9. Lung bullae \> 5 cm 10. Patients with mediastinal or hilar adenopathy with high suspicion for malignancy in whom lymph node sampling is indicated and should occur prior to robotic bronchoscopy of the peripheral lesion. 11. Patient with active COVID pneumonia.
