Clinical Comparative Study Of Single-port Vast And Multi-port Vast For Non-small Cell Lung Cancer

Background:Primary lung cancer is the most common tumor in the world.It is also the malignant tumor with the fastest increase in incidence rate in China in the past 30 years.Its incidence rate and mortality rate are both in the forefront of malignant tumors.Therefore,lung cancer research is becoming more and more important.The operative approach of radical lung cancer surgery starts with thoracotomy.It passes through classical thoracotomy,muscle-sparing(MS)incision of chest wall,and the development of thoracoscopic minimally invasive incision.At present,single-port thoracoscopic radical resection of lung cancer has become more and more common in the selection of surgical methods for radical resection of lung cancer.This paper intends to compare the perioperative indexes of single-port thoracoscopic surgery and multi-port thoracoscopic radical resection of lung cancer through retrospective study to compare the curative effects of the two.Purpose:To compare the perioperative effects of single-port thoracoscopic lung cancer radical surgery and multi-port thoracoscopic lung cancer radical surgery.Method:The data of 138 patients who underwent single-port thoracoscopic radical resection of lung cancer from September 2018 to March 2019 and did not receive radiotherapy and chemotherapy before surgery were collected retrospectively.138 patients who underwent single-port thoracoscopic radical resection of lung cancer were set as single-port group.307 patients undergoing radical lung cancer surgery under multi-port video-assisted thoracoscope were set as multi-port group.The perioperative indexes of the two groups of patients were analyzed by statistical methods.Result:Compared with the multi-port group,the single-port group has less intraoperative hemorrhage(50±50 and 100±150 ml,P=0.000),shorter average postoperative duct days(4.70±2 and 5.41±3 days,P=0.002),less drainage volume on the first day after surgery(110.0±100 and 195.0±180ml,P=0.000),and less drainage volume on the second day after surgery(107.5±97.5 and 140.0±190 ml,p = 0.040);Compared with the single-port group and the multi-port group,there was no significant difference in the incidence rate of complications(26/138 and 50/307,P=0.508),operationduration(150±75.4 and 143.5±70.5 minutes,P=0.604),hospitalization days(11.5±5 and 12.0±6 days,P=0.910),and postoperative hospitalization days5.0±3 and 6.0±3 days,P=0.058)between the two groups.Conclusion:Single-port thoracoscopic surgery is safe and feasible,and is a mature thoracic surgery technology.
