Abstract: Objective To explore the application value of individualized 3D reconstruction of lung nodules in thoracoscopic segmentectomy.
Methods Sixty patients with pulmonary nodules who underwent surgical treatment were randomly divided into three-dimensional reconstructionsimulated surgery group and non-three-dimensional reconstruction simulated surgery group in our hospital from December 2018 to December 2019,and 30 cases each group.A comparative analysis of the differences in the perioperative indicators of the two groups of patients.
Results Both groups of patients successfully completed thoracoscopic lung segmentectomy.Preoperative and intraoperative anastomosis rates of the three-dimensional reconstruction simulated surgery group were 100% of the nodule site,96.67% of the target segment blood vessel,and 96.42% of the target segment bronchus respectively.The operation time,intraoperative blood loss,drainage tube retention time,postoperative total drainage volume and postoperative hospital stay were significantly lower in the simulated surgery group than in the non-three-dimensional reconstruction simulated surgery group,the difference was statistically significant(P<0.05).There was no statistically significant difference in the number of intermediate dissection lymph nodes and the incidence of postoperative complications between the two groups(P>0.05).
Conclusion Individualized thoracoscopic anatomical segmentectomy of lung nodules based on three-dimensional reconstruction is safe and effective,and has more clinical value than conventional surgery.
