Comparison Of The Application Of Combined Hook-Wire Anchoring Nodule Under Body Surface Positioning With Intraoperative Thoracoscopy For Stereotaxis Localization And CT-Guided Hook-Wire Puncture In Thoracoscopic Pulmonary Nodule Resection

Objective To compare the clinical value of the combined Hook-wire anchoring nodule under body surface positioning with intraoperative thoracoscopy for stereotaxis localization and CT-guided Hook-wire puncture in thoracoscopic pulmonary nodule resection.Method 151 pulmonary nodules from 135 patients between May 2016 and February 2017 were selected and divided into 65 cases of surface positioning combined with intraoperative stereotactic guidance and 70 cases of CT guidance.After that,wedge resections were performed first.The success rate,complications,pathological diagnosis,operation time and hospitalization time were summarized.Results The success rate of one-time positioning of the stereotactic positioning group was 95.38% lower than that of the CT-guided group(95.71%).There was no statistically significant difference between the two groups(P>0.05);In the stereotactic positioning group,the incidence of complications was 7.7%,which was higher than 7.1% in the CT-guided group.There was no significant difference between the two groups(P>0.05);tumor location,pathological type,size of lesion diameter,positioning time,positioning success rate,operation time,wedge resection rate,postoperative hospitalization time,and postoperative extubation time were not statistically significant in the stereotactic group and the CT guided group(P>0.05).Conclusion The combined Hook-wire anchoring nodule under body surface positioning with intraoperative thoracoscopy for stereotaxis localization and CT-guided Hook-wire puncture are safe,effective,and feasible localization methods.In contrast,the stereotactic positioning does not rely on large-scale equipment,and is simple and practical.The operation success rate is high;therefore,it is worth promoting.
