Comparison of the effectiveness of anchoring needles and coils in localizing multiple nodules in the lung

Abstract

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.

Comparison of three-dimensional reconstruction and CT-guided Hook-wire segmental resection for pulmonary nodules: a propensity score matching study

“…Other methods for pulmonary nodule localization include CT-guided coil placement and medical adhesive localization [ 10 ]. Spring coil localization is a simple, quick, and highly accurate method but may lead to complications such as lung infection or bleeding during the retention process [ 11 ]. Medical adhesive can rapidly solidify inside the body to ensure accurate positioning while also blocking cut blood vessels and promoting blood coagulation, thereby reducing air leakage and bleeding caused by puncture.…”

Preoperative computed tomography-guided localization for pulmonary nodules: comparison between hook-wire and anchored needle localization

“…For those patients who underwent successful localization, resection can be readily performed with the guidance of the localization marker. However, even in some instances of technical failure, limited resection can still be performed provided the puncture site can be identified intraoperatively [ 16 ], although this may prolong the VATS procedural duration. The median VATS duration in the AN group in the present study was significantly longer than that for the HW group (80.0 min vs. 60.0 min, p = 0.002), potentially because the AN group included more patients with multiple PNs as compared to the HW group.…”

“…Relative to the HW approach, coil localization strategies are reportedly associated with significantly decreased complication rates [ 19 ]. Coil localization procedures, however, are more complex than AN or HW localization given the shape of the coil and the need to deploy its distal end adjacent to the nodule while its proximal end extends outside of the visceral pleura [ 16 ]. In some reports, AN localization has been established as a time-saving alternative to coil localization for patients with PNs [ 16 , 20 ].…”

“…Wedge/segmental resection procedures were considered a technical success when the target LN was fully present in the resected segment of tissue [ 9 ]. The duration of localization was the interval between the time at which patients initially lay down on the CT table to the time that IG injection was complete [ 13 ], while VATS time was the interval between the initial incision and wound closure [ 13 ]. Lung hemorrhage was defined based on the observation of new consolidative or ground glass opacity near the CT needle tract [ 14 ].…”
