The impact of same-day chest drain removal on pulmonary function after thoracoscopic lobectomy

Objectives This study aims to assess the feasibility and impact on long-term pulmonary function of chest drain removal on the operation day following thoracoscopic right upper lobectomy for clinical stage I non-small cell lung cancer. Methods We retrospectively evaluated the data of 116 patients between May 2013 and March 2019. We evaluated the correlations of clinical parameters of chest drain removal and medium- and long-term pulmonary function by comparing removal on operation day (R group) and retainment (D group). Results The R group comprised 64 patients, and the D group had 52 patients. Fifty patients (96.2%) in the D group had chest drain removed within 3 postoperative days. Since February 2016, chest drain removal on operation day was performed in 64 of 74 patients (86.5%) according to our chest drain removal protocol. Removal of chest drains on operation day was associated with shorter postoperative hospitalization (p < 0.01) and lower postoperative complications >= grade II of the Clavien-Dindo classification (p = 0.026). Only one patient in the R group needed reinsertion. The R group had greater spirometry results at 3- and 12-postoperative months (POM). R group patients had statistically improved pulmonary functions from 3 to 12POM, while those in the D Group were stagnated at 6POM. Conclusions Removal of chest drains on operation day using our protocol is safe and feasible for thoracoscopic right upper lobectomy. This protocol was statistically associated with slightly better long-term pulmonary function, which could not bring clinically meaningful medium- and long-term benefit.
