Comparison of three-dimensional reconstruction and CT-guided hook-wire segmental resection for pulmonary nodules: a propensity score matching study

Abstract

Abstract perioperative deaths. After PSM, 79 patients were successfully matched in each of the two groups. Two cases of pneumothorax, three cases of hemothorax and four cases of decoupling occurred in the Hook-wire group; no complications of pneumothorax, hemothorax and decoupling occurred in the 3D reconstruction group. Compared with the Hook-wire group, the 3D reconstruction group had shorter operative time Objective: To analyze and compare the clinical application value of three-dimensional reconstruction and CT-guided Hook-wire localization row lung segment resection for pulmonary nodules. Methods: Retrospective analysis of the clinical data of 204 patients with pulmonary nodules admitted to the Department of Thoracic Surgery of Gansu Provincial People's Hospital from June 2016 to December 2022. The group was divided into a 3D reconstruction group (98 cases) and a Hook-wire group (106 cases) according to the preoperative positioning method. The two groups of patients were propensity score matching(PSM) to compare the perioperative outcomes of patients in both groups. Results: All patients in both groups completed the surgery successfully with no perioperative deaths. After PSM, 79 patients were successfully matched in each of the two groups. Two cases of pneumothorax, three cases of hemothorax and four cases of decoupling occurred in the Hook-wire group; no complications of pneumothorax, hemothorax and decoupling occurred in the 3D reconstruction group. Compared with the Hook-wire group, the 3D reconstruction group had shorter operative time (P=0.001), less intraoperative bleeding (P<0.001), and shorter postoperative hospital stay (P=0.026), and there was no statistically significant difference between the two groups in terms of pathological type and TNM staging (P=0.316). Conclusion: Pulmonary nodules are based on three-dimensional reconstruction and localization, and individualized thoracoscopic anatomical lung segment resection is safe and effective with a low complication rate, which has good clinical application value.
