Surgical Lung Biopsy Technique
Surgical Lung Biopsy Technique
Video-assisted surgical lung biopsy technique
Surgical Lung Biopsy (SLB) is indicated when the scan does not show a typical UIP pattern.
The decision to suggest a video-assisted surgical lung biopsy is on the discretion of the clinician following the multidisciplinary discussion involving pulmonologists, radiologists, and pathologists involved in ILD.
This decision must take into account:
- assessment of potential risks of the biopsy and the patients willingness to participate
- age
- comorbidities
- stage of the disease
- pulmonary function testing
- how the interstitial lung disease evolves
SLB Technique
Video thoracoscopic lung biopsy is a relatively simple surgical technique, but it requires specific involvement of the surgeon to obtain a diagnosis in the majority of cases. Morbidity associated with the operation is estimated at 7% and mortality is under 1%. Morbidity is reportedly higher in patients with IPF.
It is recommended to:
- select the site that will be biopsied using the pre-op scan
- biopsy at least 2 different lobes
- make the biopsies around 3 cm
- take the biopsy from the bases of upper lobes (posterior section of the fissure) and lower lobes (diaphragm section)
- not crush the parenchyma: “No touch technic”
