CT three-dimensional reconstruction assisted preoperative planning for single-port thoracoscopic pulmonary segmentectomy clinical value
Objective To investigate the clinical value of three-dimensional reconstruction of CT images in assisting preoperative planning of single-port thoracoscopic lung segmentectomy.Methods 78 patients with pulmonary nodules who underwent single-port thoracoscopic surgery in the Department of Thoracic Oncology,Inner Mongolia Autonomous Region People's Hospital from June 2021 to June 2023 were enrolled in this study by retrospective analysis.The patients were divided into reconstruction group(n=45)and control group(n=40)according to whether preoperative three-dimensional reconstruction was performed.In the reconstruction group,CT data were collected first,and then 3D reconstruction of trachea,blood vessel,lung lobe and lung nodule was performed by mimics software.Preoperative planning was performed according to the reconstructed image,and accurate resection was performed according to the reconstructed image during operation.In the control group,the nodules were located according to preoperative CT scan and the lesions were resected.Both groups were performed by the same highly qualified surgeon.The nodule size,shape,location,operation duration,intraoperative blood loss,postoperative hospital stay,drainage tube extubation time,total drainage volume,postoperative complications and postoperative pathology were recorded in the two groups.Finally,the data were statistically analyzed to compare the clinical effects of the two groups.Resluts There was no statistical difference between the two groups in the baseline data and the size,shape and location of nodules(P>0.05).The operation time and drainage tube extubation time of the reconstruction group were significantly shorter than that of the control group,and the intraoperative blood loss was lower than that of the control group(P<0.05).There were no significant differences in postoperative hospital stay,drainage tube extubation time,postoperative pathology,and total hospital cost between the two groups(P>0.05).There was no statistical difference between the two groups in the incidence rate of postoperative complications and the incidence rate of postoperative complications in the follow-up of six months(P>0.05).Conclusion The three-dimensional reconstruction of two-dimensional CT images can assist the preoperative planning of single-port thoracoscopic pulmonary segmentectomy,which can improve the efficiency of single-port thoracoscopic pulmonary segmentectomy,make clinicians better understand the patient's condition before operation,make the operation safer,and make the patient better after recovery.It is beneficial to the diagnosis and treatment of pulmonary nodules and has great clinical application value.
