Objectives: Advances in perioperative management for thoracic surgery have accelerated the postoperative recovery of patients by decreasing postoperative pain and the incidence of complications. We aimed to study whether it's safe to remove chest drains on table in selected cases.
Methods: This was a 5-year retrospective analysis of protocolized chest-drain removal on the operating table. The chest drain was removed in patients undergoing sublobar/wedge lung resection and other minor thoracic procedure (pleural biopsy, mediastinal mass biopsy/resection) via a thoracoscopic approach (video-assisted thoracoscopic surgery). Chest drains were removed at the end of the operation if air leak as documented by the digital drain was less than 20 mL/min. Outcome data on postdrain removal pneumothorax, effusion, and need for further intervention were obtained by reviewing the postoperative chest films, all reported by a radiologist.
Results: Between 2016 and 2021, 107 patients underwent drain removal in theater. Mean age (standard deviation) was 58 (17) years and 54 (50.5%) were male. Postdrain removal pneumothorax occurred in 22 patients (21%), pleural effusion in 6 (5.6%), and 21 of 22 postoperative pneumothoraces were managed conservatively without reinsertion of chest drain. As it is our standard policy to leave no pneumothorax in patients undergoing surgical management of primary spontaneous pneumothorax, only 1 such patient (0.9%) had a drain reinserted as a result. The median (interquartile) length of hospital stay was 1 day (1-2), and 14 patients (13%) were discharged on surgery day.
Conclusions: Our results demonstrate that on table chest-drain removal in selected cases is safe and repeatable using a digital drain, challenging the practice of routine drain insertion after thoracic surgery.
