Postoperative Air Leak

This multicenter randomized trial evaluates whether routine use of Progel Platinum surgical sealant on stapled fissure lines during VATS upper or lower lobectomy for NSCLC reduces pleural drainage duration compared with standard stapling alone. Secondary objectives include postoperative length of stay, incidence and duration of postoperative air leaks, residual pleural space, safety outcomes, and hospitalization costs.
