Routine Chest X-ray After Chest Tube Removal Is Not Indicated for Minimally Invasive Lung Resection.

Abstract Background Chest x-rays after chest tube removal are common practice in post-operative thoracic surgery patients. Whether these x-rays change clinical management is debatable. We investigated prevalence and management of post-pull pneumothoraces following lung resection. Methods Retrospective review of minimally-invasive wedge-resections, segmentectomies, and lobectomies between March 2018 and September 2018. Baseline factors, operative technique, chest tube management, and outcomes following post-pull chest x-ray and factors associated with post-pull pneumothoraces were analyzed. Results 200 consecutive patients were analyzed: 117 wedge-resections (59%), 24 segmentectomies (12%), and 59 lobectomies (30%). Wedge-resections compared to segmentectomy or lobectomy had lower rates of chest tube usage, drain duration, air-leaks, and need for clamp-trial, with Blake drains most often removed last compared to segmentectomy or lobectomy (all Conclusions While routine use of post-pull chest x-ray identified a high prevalence of pneumothorax, no intervention was required. Our study demonstrates post-pull imaging may not be indicated in asymptomatic patients without prior air leak or clamp trial.
