Application Study of 12G Pigtail Catheter Used for Post-operative Drainage After Thoracoscopic Surgery for Mediastinal Nodes

Pigtail catheter(PC) has been used for thoracic drainage in the patients with pneumothorax or traumatic hemothorax/hemopneumothorax, and some study indicated that PC could obtain similar outcomes when comparing with chest tube(CT). Although PC could drain air and fluid out from pleural cavity and also help pulmonary re-expanding, rare reports are available to thoracic post-operative management. Uniportal video-assisted thoracoscopic surgery(VATS) has been widely applied in many medical center in recent years, most of mediastinal nodes could be resected under uniportal-VATS. This study aims to further study the application of 12G PC during post-operative management and comparing the validity and safety between PC(12G) and CT(16F) after uniportal-VATS for mediastinal nodes resection.
