Single-Port Video-Assisted Thoracoscopic Major Lung Resections: Experience with 150 Consecutive Cases

Abstract

Background Video-assisted thoracic surgery (VATS) for major lung resection has undergone major changes from three or four-port approach to the recently possible single-port VATS approach. Outcomes following single-port VATS major lung resection are analyzed to determine safety and efficacy.

Methods A prospective database of 150 consecutive patients who underwent single-port VATS major lung resection between March 2012 and January 2014 was reviewed. Patient demographics, perioperative parameters, histopathology, and outcomes up to follow-up of 2 years were analyzed by descriptive and Kaplan–Meier survival statistics.

Results Single-port VATS major lung resection was successfully performed in 142 patients (conversion rate 5.3%) for both malignant and benign diseases of the lung. Overall, 130 patients (87%) had nonsmall-cell lung carcinoma (NSCLC), 9 (6%) had other types of primary lung cancer, and the remaining for secondary malignancies and benign diseases. Among the 130 patients with NSCLC, 93 (71.5%) were stage I, 28 were stage II (21.5%), and 9 (7%) were stage III or greater. There was no intraoperative or 30-day mortality. However, one perioperative death occurred on day 49, and another on day 60 postoperatively due to infective causes. The overall 2-year mortality rate for all patients was 3%. The disease-free survival rate for subgroups, stage I NSCLC, and stage II or greater NSCLC were 96 and 83%, respectively.

Conclusions Single-port VATS major lung resection for malignant and benign lung diseases is associated with low perioperative morbidity and mortality. Disease-free survival rates for NSCLC are acceptable and comparable with conventional VATS.
