The Feasibility and Safety of Avoiding Chest Tube Placement After Video-assisted Thoracoscopic Surgery (VATS）of the Lung

Study Overview
=================
Brief Summary
-----------------
This is a prospective randomized controlled trial.The main study content is the feasibility and safety of avoiding chest tube placement after Video-Assisted Thoracoscopic Surgery lung disease,participants were randomly divided into experimental group and control group.Avoiding chest tube placement after VATS of the lung in the experimental group.Indwelling thoracic drainage tube after VATS of the lung in the control group.

Detailed Description
-----------------
This is a prospective randomized controlled trial.The main study content is the feasibility and safety of avoiding chest tube placement after VATS of the lung,divided into experiment group and control group.Communicating with surgeon and patients who met the inclusion criteria,decided whether to enter the experimental group or control group. Experimental group avoid chest tube placement after VATS of the lung and control group indwell thoracic drainage tube after VATS of the lung.By collecting personal information of two groups of patients and the corresponding observation indicators to analyze whether the treatment of avoiding chest tube placement after VATS of the lung is more beneficial than the conventional indwell thoracic drainage tube after VATS of the lung,and it's safe and feasible.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| operation time | From the beginnning of ansesthesia to the end of anesthesia | 1 day | 
| hospitalization expenses | the total cost of hospitalzation | 15 days | 
| postoperative complication rate | incidence of postoperative complications such as pneumothorax and hydrohorax | a month | 
| duration of postoperation pain | postoperative pain duration | 10 days | 
| VAS pain scores | the VAS pain score was given to patients and the pain scores were recorded at 6h,12h,24h,48h,and 72h postoperatively.The minimum score is 0 and the maximum score is 10.The high values represent a worse outcome. | 3 days | 
| the time of early ambulation after operation | the time from the patient's postoperative pushback to the first bedtime | 1 day | 
| postoperative extubation time | postoperative extubation time | 1 day |
