Study on the Application Effect of Three-dimensional Reconstruction Technology in Locating Small Pulmonary Nodules
Objective:
To compare the positioning effect of three-dimensional reconstruction technology and Hook-wire puncture operation on small pulmonary nodules during video-assisted thoracoscopic surgery (VATS), and evaluate its effectiveness, efficiency, and safety.
Methods:
The subjects of this study were 50 patients with small pulmonary nodules admitted to the Department of Cardiothoracic Surgery of Heilongjiang Provincial Hospital from January 2020 to December 2022, and all underwent thoracoscopic surgical resection. All study subjects met the inclusion criteria, grouping according to the intraoperative positioning method, the control group (n = 25) used Hook-wire puncture positioning, and the observation group (n = 25) used three-dimensional reconstruction technology. The positioning effect, pain level, and postoperative complications were compared between the two groups.
Results:
The incidence rate of complications after puncture was 16.00% in the control group and 4.00% in the observation group, the complication rate in the observation group was significantly lower; the positioning success rate of the observation group was 96.00%, which was higher than that of the control group (92.00%). The operation time (32.25±6.08) min was lower than (38.50±7.12) min in the control group. The two groups had no statistical significance in the wedge resection success rate, VAS score, and complication rate (P > .05).
Conclusion:
Three-dimensional reconstruction technology mainly makes preliminary judgments on the location, shape, size, and relationship between nodules and surrounding tissues based on preoperative CT scan images. It can select suitable scanning locations, map puncture paths, and anchor them in and around small lung nodules. The operation is simple, and the positioning success rate is high. The existence of three-dimensional reconstruction technology to position the guide wire can quickly shorten the time to detect lesions, shorten the time of VATS, reduce the occurrence of pulmonary infection in patients, and improve the prognosis.
