Abstract
BACKGROUND: Risks associated with video-assisted surgical lung biopsy (VASLB) for interstitial lung disease (ILD) with endotracheal intubation and mechanical ventilation are not nil. Awake video-assisted surgical lung biopsy (Awake-VASLB) has been proposed as a method to obtain a precise diagnosis in several different thoracic diseases. OBJECTIVES: To compare clinical outcomes of Awake-VASLB and Intubated-VASLB in patients with suspected ILDs. METHODS: From June 2016 to February 2020, all patients submitted to elective VASLB for suspected ILD were included. Differences in outcomes between Awake-VASLB and Intubated-VASLB were assessed through univariable, multivariable-adjusted, and a propensity score-matched analysis. RESULTS: Awake-VASLB was performed in 66 out of 100 patients, while 34 underwent Intubated-VASLB. The Awake-VASLB resulted in a lower post-operative morbidity (OR 0.025; 95% CI 0.001-0.35; p=0.006), less unexpected intensive care unit admission, less need for rescue therapy for pain, a reduced surgical and anaesthesiologic time, a reduced chest drain duration, and a lower post-operative length of stay. CONCLUSION: Awake-VASLB in patients affected by ILD is feasible and seems safer than Intubated-VASLB.
