We believe that most of the stress (patient and surgeon) during VATS anatomical lung resection originates from manipulation of the pulmonary arteries. Endostaplers utilized during VATS to seal the pulmonary arteries require a lot of space and manipulation of these fragile vessels. Furthermore, the arteries must be completely dissected from the surrounding tissues. This increases manipulations of pulmonary arteries during the procedure. Energy sealing devices require much less space and dissection due to their size and sealing of the arteries can be performed without complete dissection from the surrounding tissues. Thus, the utilization of energy sealing devices will decrease excessive manipulations on the pulmonary arterial branches during VATS anatomical lung resections which can render these procedures easier and safer. This will not only decrease the stress on the patient, but also on the surgeon and will hopefully allow more surgeons to adopt these minimally invasive techniques which have been proven to be superior (length of stay, cost of care, pain, morbidity post-op, atrial fibrillation, quality of life, systemic inflammation, ability to receive adjuvant chemotherapy) to open thoracotomy.
