Final answer:
VATS is used for a lobectomy in patients with lung cancer, providing less discomfort and a faster recovery.
Step-by-step explanation:
Video-assisted thoracic surgery (VATS) is used to perform a lobectomy. The reason for using this type of surgery is to remove a portion of the lung, typically due to lung cancer. VATS allows for smaller incisions and the use of a video camera to guide the procedure, resulting in less discomfort and a faster return to normal activity for the patient.
