Objectives
There is no evidence concerning the appropriate drainage volume for indicating chest tube removal after pulmonary lobectomy. A prospective multi-institutional cohort study was designed to elucidate the safety of early chest tube removal after thoracoscopic lobectomy.
Methods
Between April 2009 and November 2011, 310 patients with suspected or histologically documented lung cancer were screened. Patients without air leakage or bloody, chylous, or purulent pleural effusion underwent chest tube removal on the day after thoracoscopic lobectomy, independent of the drainage volume. The subjects were classified into three groups as tertiles according to the drainage volume that was observed for approximately 24 h after surgery. The associations between the drainage volume and the development of complications were investigated, with several clinical factors taken into account.
Results
The 162 patients who were enrolled underwent early chest tube removal via this protocol and were classified into three groups according to their drainage volume (0–219 mL, n = 52; 220–349 mL, n = 56; and ≥ 350 mL, n = 54). A 7F backup tube placed within the dead space to prevent troubles was removed by postoperative day 4 in all patients because nothing happened. Univariate and multivariate analyses showed that the drainage volume was not associated with the risk of complications.
Conclusions
Early removal of the chest tube on the day after thoracoscopic lobectomy appears to be a safe treatment protocol in patients without air leakage or bloody, chylous, or purulent pleural effusion; however, careful surveillance is needed for patients who have a drainage volume of ≥ 350 mL/day.
