“…Effective preoperative localization can help thoracic surgeons and pathologists to quickly locate tumor nodules intraoperatively (9). Current location technology is varied, and includes liquid material positioning technology (methylene blue, iodine oil, medical glue, barium sulfate, radionuclide), solid material positioning technology, other positioning technologies (ultrasonic orientation and near infrared scan), and so on (10,11). Each technology shows obvious advantages and disadvantages.…”

“…In cases where mild pneumothorax and pneumorrhagia appeared along the path of puncture needle, the second marked spring coil would immediately block the puncture passage. Relevant studies have shown that positioning-related complications may be a consequence of unskilled operation, excessively superficial lesions, exceedingly shallow depth of the spring coil release, and nodules that are hidden in the interlobar fissure (7,11). Experienced and proficient operators have a better potential to complete the operation (9,12).…”

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-hookanchor 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.

“…The accurate localization of small PNs and ground glass nodules remains challenging in thoracoscopic surgery, and effective preoperative positioning can help thoracic surgeons quickly locate tumor nodules during surgery [9]. In addition, liquid material (methylene blue, iodide oil, medical glue, barium sulfate, radionuclide, and autologous blood), solid material, and other (ultrasonic positioning and near-infrared scanning) positioning technologies can be effective [10,11]. Regarding the preoperative positioning technology for PN, the most reported invasive preoperative positioning methods are CT-guided Hook-wire and micro-spring ring positioning [12].…”

Background To investigate the risk factors of pneumothorax of using computed tomography (CT) guidance to inject autologous blood to locate isolated lung nodules. Methods In the First Hospital of Putian City, 92 cases of single small pulmonary nodules were retrospectively analyzed between November 2019 and March 2023. Before each surgery, autologous blood was injected, and the complications of each case, such as pneumothorax and pulmonary hemorrhage, were recorded. Patient sex, age, position at positioning, and nodule type, size, location, and distance from the visceral pleura were considered. Similarly, the thickness of the chest wall, the depth and duration of the needle-lung contact, the length of the positioning procedure, and complications connected to the patient’s positioning were noted. Logistics single-factor and multi-factor variable analyses were used to identify the risk factors for pneumothorax. The multi-factor logistics analysis was incorporated into the final nomogram prediction model for modeling, and a nomogram was established. Results Logistics analysis suggested that the nodule size and the contact depth between the needle and lung tissue were independent risk factors for pneumothorax. Conclusion The factors associated with pneumothorax after localization are smaller nodules and deeper contact between the needle and lung tissue.

“…2 In their article, "Microcoil-guided video assisted thoracoscopic excision of nodules suspicious for metastasis in patients with extra-thoracic malignancies," Almousa et al address this diagnostic challenge. 3 Using microcoils placed under CT-guidance, the authors were successful in determining a diagnosis thoracoscopically (one patient was converted to thoracotomy due to extensive adhesions) in 98% of patients with nodules of a mean size of 12 mm and a mean depth of 22 mm from the visceral pleura. Moreover, the technique resulted in the earlier diagnosis of metastatic extrathoracic malignancies or primary pulmonary malignancies in nodules that may have otherwise been followed with continued surveillance.…”
