Breath Hold Not Linked to Better Lung Lesion Biopsy Yield

A recent study contradicts the belief that sustained breath holding enhances lung nodule biopsy accuracy using robotic bronchoscopy. The randomized trial, known as the STABLE trial, found no significant difference in diagnostic yield between breath hold and conventional ventilation methods, both at 86.8% and 92.2% respectively. Localization rates were also similar at 98.1% and 95.3%.

Roshen Mathew, MD, of WVU Medicine, emphasized the importance of dynamic imaging and tool-lesion alignment over static imaging and breath holding. The study included 117 patients with peripheral pulmonary lesions, with mean lesion size around 1.7 cm. Despite the findings, Mathew cautioned that larger lesions might benefit more from the breath hold technique. The study, however, is considered an exploratory analysis, necessitating further research.
