“…11 Hsu et al detected 91 indeterminate pulmonary nodules (62 pGGNs, 27 psGGNs, and 2 solid nodules) with a success rate of 100%. 12 Our results are consistent with these studies. Pathologically, a high ratio of malignancy was observed (89.5%) in our study, which may be because surgeons preoperatively screened the target nodules.…”

BackgroundThis retrospectively study was conducted to assess the efficiency and safety of computed tomography (CT)‐guided hook wire localization of pulmonary ground‐glass nodules (GGNs) prior to video‐assisted thoracoscopic surgery (VATS).MethodsFrom 2015 to 2018, a total of 86 patients with 86 pulmonary GGNs underwent preoperative CT‐guided hook wire localization before VATS. The technical details and clinicopathological findings were analyzed.ResultsAll 86 pulmonary GGNs (25 pure GGNs and 61 part‐solid GGNs) were successfully located and resected. The mean diameter of the GGNs was 1.4 ± 0.4 cm (range 0.6–2.2) and the mean lesion distance to the pleural surface was 7.3 ± 4.3 mm (range 2–19). Complications of hook wire marking included asymptomatic minor pneumothorax in 21 patients (24%) and focal pulmonary hemorrhage in 18 (21%). The median hook wire localization time was 19.1 minutes (range 10–30) and the median VATS time was 49 minutes (range 28–89). Pathology revealed 72 precancerous lesions or primary lung adenocarcinomas, 5 metastatic tumors, and 9 benign lesions.ConclusionsPreoperative localization of small pulmonary GGNs using CT‐guided hook wire was efficient and safe prior to VATS resection.

“…As SPNs are small and soft, subcentimeter nodules are difficult to find by touch, and without preoperative localization, complete and accurate resection by thoracoscopic surgery is very difficult . Since the initial report describing the high accuracy of hookwire localization for VATS was published in 1992 by Plunkett et al .…”

“…Our research data showed that the success rate was 97.2% (69/71) in the microcoil group and 94.4% (67/71) in the hookwire group, and the difference was not statistically significant ( P = 0.404), indicating that the microcoil and hookwire are effective localization technologies. A meta‐analysis in 2006 screened the English literature from 1992 to 2016, including 2365 patients who underwent hookwire localization and 459 patients who underwent microcoil localization; the success rates of the two localization methods were 98% (95% CI: 0.97–0.99) and 98% (95% CI: 0.96–0.99), respectively, and the success rates of VATS resection were 96% (95% CI: 0.94–0.97) and 97% (95% CI: 0.94–0.99), respectively.…”

Background: The purpose of this study was to compare the efficacy and safety of two preoperative pulmonary nodule localization techniques using microcoil and hookwire. Methods: A total of 307 patients with 324 pulmonary nodules were included in the study from March 2012 to October 2016 in two medical centers. Baseline data, positioning operation data, success rate, complications, surgery and pathological results were statistically analyzed. Complications were used as the dependent variables, whereas others were used as covariates for the propensity score matching of the two groups. Statistical analyses were performed to compare the success rate and complication rate of the matched groups. Results: There were 218 lesions in the microcoil group and 106 nodules in the hookwire group. There were no significant differences in gender, age and the location of nodules between the two groups. The diameters of the nodules were smaller (8.2 AE 3.5 mm vs. 10.7 AE 4.3 mm) and solid nodules were fewer (11.5% vs. 26.4%) in the microcoil group. The complication rate of the two groups was not statistically significant. After propensity score matching, 71 patients in each group were successfully matched. We found that the success rate was higher (97.2% vs. 94.4%) and the incidence of complications was lower (31% vs. 15.5%) in the microcoil group. Conclusions: Both techniques have been shown to be effective in preoperative localization of tiny pulmonary nodules. The method of microcoil localization has more advantages in clinical application. Key pointsComparison of the efficacy and safety of two methods in preoperative pulmonary nodule localization in order to determine the optimal method.

Background: Unhooking or displacement of hookwire or microcoil due to technical failures is rather common. We aim to establish a new technique for remedial localization in the case of displacement or unhooking of primary mechanical localization during lung surgery. Methods: From February 2014 to September 2015, 18 consecutive cases of intraoperative dislodgement during video-assisted thoracoscopic surgery (VATS) were enrolled. Nodule's projection on body surface was located by analyzing computed tomography (CT) images, and a needle was inserted into thoracic cavity through this point. The lung was then inflated, and a small burn was made where the needle tip touched the visceral plural. Wedge resections were subsequently performed for these impalpable small lesions. Results: Eighteen solitary pulmonary nodules (SPNs) from 18 patients were scheduled for VATS wedge resections in this series, including 6 (33.3%) hookwire localization and 12 (66.7%) microcoil localization.Fifteen (83.3%) of 18 nodules were pure ground glass opacity (pGGO) and 3 (16.7%) mixed ground glass opacity (mGGO). The mean diameter of SPNs was 7.7±3.6 mm. The mean distance from SPN to pleura was 12.2±10.9 mm. During remedial localization, 17 (94.4%) nodules were removed successfully by wedge resection, and segmentectomy was performed only in one case with failed outcome. Paraffin pathology showed 2 (11.1%) atypical adenomatous hyperplasia (AAH), 11 (61.1%) adenocarcinoma in situ (AIS), 4 (22.2%) minimally invasive adenocarcinoma (MIA), and 1 (5.6%) inflammatory disease.Conclusions: This remedial localization technique is practical and reliable. It is a good backup plan in the case of dislodgement, and it can help prevent extended lung resection.
