“Video-assisted thoracoscopic surgery (VATS) is a well established procedure, but patients with poor pulmonary function often cannot have it because it is risky for them to go under general anesthesia,” says study author Ara Klijian, MD, of Sharp Grossmont Hospital, La Mesa, California and Scripps Mercy Hospital, San Diego. “I extended the VATS procedure so that it is done under local anesthesia with sedation. This enabled me to do a variety of procedures including lobectomies, esophageal surgeries, decortications and other types of thoracic surgery, with better outcomes.”
Over the last 5 years, Klijian has performed more than 500 AVATS procedures without significant mortality or morbidity. In the current study, 246 patients with lung cancer had the AVATS procedure. Klijian demonstrated that patient safety was not compromised, that patients had a lower length of stay (1.6 days for patients who had a lobectomy, or removal of a lung), and better patient satisfaction.

Patients receiving the AVATS procedure typically have multiple chronic health conditions, as described in the abstract below, and poor lung function, which would typically increase the risk of surgical complications.
“By eliminating the need for endotracheal intubation and the comorbidity associated with general anesthesia, the AVATS procedure brings new, previously considered inoperable patients into the surgical arena,” Klijian says. “My long-term data have shown that this approach has better outcomes than traditional lung surgery with this select group of patients. It also reduces risks of hospital-acquired infection, as outpatient postoperative care minimizes the use of catheters.”
In the AVATS and VATS procedures, a tiny camera (thoracoscope) and surgical instruments are inserted into the chest through small incisions in the chest wall. The thoracoscope transmits images of the inside of the chest onto a video monitor, guiding the surgeon in performing the procedure.
The availability of the AVATS procedure is expected to increase, as Klijian has presented the technique and trained a number of other surgeons.
