Abstract: Objective To explore the feasibility of improving the indwelling technique of drainage tube orifice after single-port thoracoscopic lung cancer surgery and analysis of drainage effect.Methods The clinical data of 80 patients who underwent single-port thoracoscopic radical resection of lung cancer who were admitted to Ningbo Huamei Hospital,University of Chinese Academy of Sciences from January to December 2021 were retrospectively analyzed,and they were divided into observation group and control group according to the different drainage tube indwelling techniques.Postoperative drainage tube indwelling time,postoperative hospital stay,postoperative total drainage volume,intraoperative blood loss,operative time,incision infection,postoperative pain score,and drainage port healing.Results The postoperative incision exudation,poor incision healing,incision infection,drainage tube indwelling time,and postoperative hospital stay in the observation group were better than those in the control group,and the differences were statistically significant(P<0.05).There were no significant differences in the total drainage volume,intraoperative blood loss,operation time,and secondary suture rate of the incision(P>0.05).Conclusion The single-port thoracoscopic surgery is beneficial to reduce the incidence of postoperative incision infection and incision exudation,shorten the indwelling time of the drainage tube,improve the safety of extubation,and shorten the hospitalization of patients.time.
