Abstract: Objective To explore the clinical application and effect of an improved method of drainage tube fixation and incision suture after thoracoscopic surgery. Methods Between February 2020 and October 2020,202 patients who underwent video-assisted thoracic surgery in Department of Lung Cancer,Tianjin Medical University Cancer Institute and Hospital were enrolled in this study.All patients used an improved drainage tube fixation and incision suture method. Results All 202 patients have no obvious leakage.To a certain extent,this improved method can well improve the problem of easy leakage of thoracoscopic drainage nozzle after surgery,promote rapid wound healing,significantly reduce postoperative scar hyperplasia,and thus improve the incision aesthetics. Conclusion The improved method of drainage tube fixation and incision suture after thoracoscopic surgery has achieved satisfactory results in clinical practice.
