Following vascular sealing, experimentation and recordings, the specimen will be sent for pathological evaluation of the resected lesion. All specimen manipulations will be strictly performed on the proximal main PA branches, away from the resected tumour. Care will be taken to not affect the pathological integrity of the resected lesion and its surrounding tissue and lymph nodes. Experimentation will be performed under the direct supervision of the attending thoracic surgeon in order to assure integrity of the specimen for pathological analysis.
