Clinical Study Of Thoracoscopic Pulmonary Wedge Resection With On Without Chest Tube Placement For Peripheral Lung Nodules

ObjectiveTo observe the feasibility and safety of avoiding drainage tube placement in VATS pulmonary wedge resection.MethodsA total of 109 patients who underwent VATS pulmonary wedge resection in the same treatment group in the department of thoracic surgery,the first affiliated hospital of Chongqing medical university from January2019 to April 2020 were collected.Forty-one(observation group)patients avoid chest drainage while 68 patients(control group)received routine chest catheter placement.According to the clinical characteristics of patients in each group,1:1 propencity score was matched,and the postoperative clinical parameters(operation time,postoperative hospital stay,etc.)were compared between the matched groups.ResultsThe two groups of patients successfully completed the surgery underthoracoscopy,and there was no perioperative death or transition to thoracotomy.There was no statistically significant difference in the total cost and intraoperative blood loss between the two groups(p>0.05).The lesion diameter of the observation group was smaller than that of the control group(9.4±5.1 mm vs 11.44± 6.6mm,p<0.05).Postoperative hospital stay and postoperative analgesic use time of the observation group were lower than those of the control group(1.6±0.8d vs 3.9 ±2.3d,1.2±0.5d vs 3±2.3d,p<0.001).Among postoperative complications,there was no significant difference in the incidence of postoperative delayed pneumothorax between the observation group and the control group.The incidence of postoperative subcutaneous emphysema in the observation group 65.7% was higher than that 28.1% in the control group.ConclusionIt’s feasible and safe for avoiding drainage tube placement in VATS pulmonary wedge resection for some suitable patients avoiding.
