The groups were similar in demographics, comorbidities, lobe resected, and lung pathology. Length of stay, chest tube days, and chest tube drainage were less in the single tube group; however, they did not achieve statistical significance. Similarly, post-operative airleak and residual pneumothorax after tube removal were not significantly different but were less in the single tube group. While the post-operative day to oral pain control was similar in the single and double chest tube groups, postoperative pain as assessed by the VAS pain scale was lower in the single tube group each of the first four PODs with the difference achieving significance on postoperative days 3 (3.6 ± 0.5 versus 5.9 ± 0.5) and 4 (3.2 ± 0.6 versus 5.4 ± 0.6).
