“…In those two cases, following the location of the first pulmonary nodule, a small amount of pneumothorax appeared, and the visceral pleura was folded on itself when the needle tip was re-punctured, preventing the puncture needle from effectively entering the lung parenchyma. This situation has been reported in many studies [ 2 , 4 , 12 ]. After carefully analyzing the reasons, we propose that: (1) The lung tension decreased following the occurrence of pneumothorax [ 4 , 13 ]; (2) The needle tip of the positioning needle is a hollow wedge-shaped structure; (3) There were other tissues such as thick blood vessels near the target pulmonary nodule.…”

“…We also observed, that in some cases the pathological results of multiple pulmonary nodules from the same patient were different, and the proportion of such cases in the needle group and the coil group was as high as 55.0% and 54.8%, respectively, which reflected that the patients with multiple pulmonary nodules were evaluated for a single nodule. It also indicates the importance of single-stage localization and wedge resection of multiple pulmonary nodules [ 12 ].…”

Background Recently, a new type of pulmonary nodule positioning needle has been adopted clinically. We aimed to evaluate the efficacy and safety of a new type of localization needles compared with coils for the simultaneous localization of multiple pulmonary nodules guided by computed tomography (CT) prior to video-assisted thoracoscopic surgery (VATS). Materials and methods From January 2021 to March 2022, 87 pulmonary nodules from 40 patients were localized using the new localization needle. From January 2020 to December 2020, 68 pulmonary nodules in 31 patients were localized using coils. The relative outcomes were compared. Results The success rate of pulmonary nodule localization in the needle group was 97.7% while that in the coil group was 98.5%. In the needle group, the time needed to locate the first nodule was significantly shorter than in the coil group (10.9 min vs. 17.2 min, P = 0.001). Moreover, the time needed per patient was also significantly shorter for the needle group compared with the coil group (23.7 min vs. 30 min, P = 0.017). The incidence of pneumothorax in the needle group was 25.0% vs. 12.9% in the coil group (P = 0.204). The rate of pulmonary hemorrhage in the needle group was 40.0% vs. 32.3% in the coil group (P = 0.502). The success rate of VATS wedge resection was 100% in both groups. Conclusion Both disposable pulmonary nodule localization needles and coils are safe and effective for CT-guided localization of multiple pulmonary nodules of the same stage prior to VATS. However, the use of needles is time-saving compared with the use of coils. The coil localization may exhibit better safety than needle localization.

In the needle group, the time needed for locating the first nodule was significantly shorter compared with the coil group (10.9 min vs. 17.2 min, P<0.05). Moreover, the time needed per patient was also significantly shorter for the needle group compared with the coil group (23.7 min vs. 30 min, P<0.05). The incidence of pneumothorax in the needle group was 25.0% vs. 12.9% in the coil group (P>0.05). The rate of pulmonary hemorrhage in needle group was 40.0 % vs 32.3% in coil group (P>0.05). The success rate of VATS wedge resection was 100% in both groups. Conclusions: Both disposable pulmonary nodule localization needles and coils are safe and effective for CT-guided localization of multiple pulmonary nodules of the same stage prior to VATS. However, the needles are time-saving to use than the coils.

“…Currently, many different localization techniques have been applied in clinics to facilitate the successful resection of pulmonary nodules, including hookwire under the guidance of preoperative CT, microcoil, methylene blue, or lipiodol fiducial marker (3)(4)(5)(6)(7). Among these, the hookwire is the most widely-used device for the preoperative localization of pulmonary nodules owing to its reliable successful localization rate (80.6-99.6%), short localization duration, and low cost (8)(9)(10).…”

Background: In our previous study, we developed a 4-hook claw-suture localization device for pulmonary nodule resection, which acheived satifisfactory results. Following this, we conducted this single-center, openlabel, randomized clinical trial to compare the success rate and complication rate of this novel localization device and currently widely-used hookwire.Methods: Patients with small pulmonary nodules (0.4-1 cm) who received preoperative localization and thoracoscopic resection at Shanghai Chest Hospital were randomly assigned (1:2 ratio, via computergenerated randomized numbers) to undergo localization using either a novel claw-suture system (claw group) or classical (hookwire group) localization device. The primary endpoint of this study was localization success rate, and the secondary endpoints included complications, localization-related time, and pain.Results: A total of 411 patients were randomly assigned to the claw group (n=136) or the hookwire group (n=275) before thoracoscopic resection of small pulmonary nodules and analyzed. Compared with the hookwire group, the claw group had a significantly higher success rate (133/136, 97.8% vs. 254/275, 92.4%, P=0.027), less asymptomatic hemorrhage (16.9% vs. 37.5%, P=0.003) and pleural reaction (0% vs. 5.1%, P=0.017), as well as better pain alleviation 10 min after localization (measured using the difference between two visual analog scale scores, 0.84±0.98 vs. 0.35±0.79, P<0.001). In contrast, the hookwire group was associated with a shorter localization procedure duration than the claw group (7.2±2.9 vs. 14.4±6.6 min, P<0.001). In the multiple localization subgroup, the claw group compared to the hookwire group also achieved higher success (32/33, 97.0% vs. 70/86, 81.4%) and less pleural reaction (0% vs. 16.3%). Conclusions:The new claw-suture localization device is superior to traditional hookwire, with a higher success rate, fewer complications, and better patient tolerance for preoperative localization of small pulmonary nodules.
