Abstract
Background
Preoperative localization of small size pulmonary nodules is challenging, but it is necessary for surgical resection of early lung cancer. As a new device for preoperative localization, the 4-hook-anchor coaxial needle with scaled suture was tentatively applied in our department to improve the effect of preoperative localization. However, double spring coil, as a proven positioning technology, used to be our preferred method in the past. We did a retrospective single-centre research driven by the interest on which one should be the first choice for preoperative localization among these two approaches.
Methods
We performed a retrospective analysis on 100 patients undergoing surgery with the new coaxial needle from 2019 to 2020, and 98 patients undergoing double spring coil from 2017 to 2019. The duration of localization, success rate, operation time, intraoperative bleeding, and positioning-related complications of these two groups of patients were examined in this study.
Results
There were no significant differences between the two groups of patients in terms of the success rate. However, the new coaxial needle seemed to be able to shorten the duration of preparative localization and operation time by accelerating the efficiency of exploring small nodules intraoperatively, and also decreased the risk of positioning-related pneumothorax and pulmonary hemorrhage. The logistic analysis indicated that the puncture depth was an independent risk factor for overall complications. Meanwhile, previous lung diseases and positioning time were independent risk factors for pneumothorax, besides pneumorrhagia and depth of penetration as well.
Conclusions
The new coaxial needle can save time for both radiologists and thoracic surgeons, while reducing the risk of positioning-related complications. We support its application clinically instead of the double spring coil.
