The decision to omit chest-tube drainage was originally made on a case-by-case basis, using internal criteria. Postoperative chest radiography was performed on the day of surgery, on postoperative day 1, at the first outpatient visit, and at 1\u00a0month after surgery.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 134 patients met the selection criteria; 23 (17.2%) had residual pneumothorax on chest radiography on postoperative day 1, and 5 (3.7%) had residual pneumothorax at the first outpatient visit. Only 1 patient (0.7%) had residual pneumothorax on chest radiography at 1\u00a0month after surgery; this patient did not require chest-tube insertion or any other intervention. The presence of partial pleural adhesions independently increased the risk for postoperative residual pneumothorax on chest radiography, whereas older patient age reduced the risk.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Uniportal video-assisted thoracoscopic surgery for pulmonary wedge resection without drainage-tube placement is both safe and feasible for carefully selected patients.
