Modified Versus Traditional Thoracic Drainage After Thoracoscopic Surgery

Study Overview
=================
Brief Summary
-----------------
Lung cancer is the leading cause of cancer-related death worldwide. Thoracoscopic pulmonary resection is a prevalent management for early stage of lung cancer. Placement of traditional chest tube is the standard procedure after surgery, which causes pain that cannot be ignored. We aimed to determine whether a modified thoracic drainage strategy based on pigtail catheter associated with better clinical results compared with traditional methods after thoracoscopic surgery for lung cancer.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: modified thoracic drainage group<br>After surgery, both a chest tube and a pigtail catheter are inserted into the middle and posterior axillary lines of the 7th intercostal space, respectively. | Procedure: pigtail catheter<br>* After inserting the chest tube, add a pigtail catheter into the posterior axillary lines of the 7th intercostal.<br>|
| No Intervention: traditional thoracic drainage group<br>After surgery, only a chest tube is inserted into the midaxillary line of the 7th intercostal space, traditionally. | |
