Standardized Approach to Prolonged Air Leak Reduction After Pulmonary Resection.

BACKGROUND: Prolonged air leaks after pulmonary resection lead to patient discomfort, increased hospital length of stay, greater health care costs, and increased morbidity. A standardized approach to air leak reduction (STAR) after lung resection was developed and studied. METHODS: A retrospective review was conducted of a prospective database from 1 surgeon who had adopted STAR as standard of care. Three independent factors shown to reduce air leaks are incorporated in STAR: fissureless operative technique, staple line buttressing, and protocol-driven chest tube management. Patient characteristics and outcomes were compared against aggregate data from The Society of Thoracic Surgeons National Database (2012-2014). RESULTS: From June 2010 through May 2015, 475 patients met the study criteria. Of these, 264 (55.6%) had lobectomies, 198 (41.7%) had wedge resections, and 13 (2.7%) had segmentectomies. Prolonged air leaks were reduced in the STAR lobectomy group by 52% (5.7% versus 10.9%; p = 0.0079) and in the STAR wedge group by 40% (2.5% versus 4.2%; p = 0.38). Hospital length of stay for lobectomies (3.2 versus 6.3 days; p = 0.0001), wedge resections (3.3 versus 4.5 days; p = 0.0152), and segmentectomies (3.2 versus 5.2 days; p = 0.0001) was significantly reduced. Readmission rate was 4% and none were related to air leak. No difference was seen in mortality rates. CONCLUSIONS: Use of STAR for pulmonary resection, particularly for lobectomies, shows decreased postoperative prolonged air leaks when compared with The Society of Thoracic Surgeons National Database. This aggressive approach did not lead to air leak-related hospital readmissions nor compromise postoperative mortality. The STAR protocol is an innovative strategy that has the potential to improve postoperative pulmonary resection outcomes.

Safety of Outpatient Chest Tube Management of Air Leaks After Pulmonary Resection.

Prolonged air leaks are the most common postoperative complication following pulmonary resection, leading to increased hospital length of stay (LOS) and cost. This study assesses the safety of discharging patients home with a chest tube (CT) after pulmonary resection. A retrospective review was performed of a single surgeon's experience with pulmonary resections from January 2010 to January 2015. All patients discharged home with a CT were included. Discharge criteria included a persistent air leak controlled by water seal, resolution of medical conditions requiring hospitalization, and pain managed by oral analgesics. Patient demographics, type of resection, LOS, and 30-day morbidity and mortality data were analyzed. Comparisons were made with the Society of Thoracic Surgery database January 2011 to December 2013. Four hundred ninety-six patients underwent pulmonary resection. Sixty-five patients (13%) were discharged home postoperatively with a CT. Fifty-eight patients underwent a lobectomy, two patients a bilobectomy, and five patients had a wedge excision. Two patients were readmitted: One with a lower extremity deep venous thrombosis and the other with a nonlife threatening pulmonary embolus. Four patients developed superficial CT site infections that resolved after oral antibiotics. Patients discharged home with a CT following lobectomy had a shorter mean LOS compared to lobectomy patients (3.65 vs 6.2 days). Mean time to CT removal after discharge was 4.7 days (range 1-22 days) potentially saving 305 inpatient hospital days. Select patients can be discharged home with a CT with reduced postoperative LOS and without increase in major morbidity or mortality.
