Non-small Cell Lung Cancer (NSCLC)
Conditions
Brief summary
Collection of real world outcomes of Video-Assisted Thoracoscopic Surgery (VATS) for lung cancer (lobectomy, wedge resection) using ECHELON FLEX™ Powered ENDOPATH® Staplers 45 mm and/or 60 mm (study devices) in a Korean population.
Detailed description
This clinical trial assessed the use of a powered stapler for transection in VATS lung resection, where there is currently limited published clinical data. The primary study endpoint was occurrence and duration of air leak / prolonged air leak (PAL). Procedure details and perioperative outcomes associated with VATS lung resections were also evaluated.
Interventions
The study utilized Echelon FlexTM Powered ENDOPATH® Stapler (Ethicon, Cincinnati, USA) along with compatible cartridges: Gray (closed staple height, 0.75mm), White (1.0mm), Blue (1.5mm), Gold (1.8mm), Green (2.0mm), and Black (2.3mm).

Participant flow
Recruitment details
Individuals undergoing VATS lobectomy for suspected or confirmed Non-small Cell Lung Cancer, or individuals undergoing VATS diagnostic wedge resection in accordance with their institution's Standard of Care, and who meet study entry criteria, were enrolled in this study.
Pre-assignment details
There was no assignment to treatment group given that this is a single arm study wherein the same device was used on all subjects. Results are presented for the overall cohort as well as by the individual procedure performed - lobectomy, wedge resection, or wedge resection with lobectomy.
