Abstract
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.

[PMID: 38336734 PMCID: PMC10858508 DOI: 10.1186/s12957-024-03331-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Accepted: 02/02/2024] [Indexed: 02/12/2024] Open
Abstract
BACKGROUND Presurgical computed tomography (CT)-guided localization is frequently employed to reduce the thoracotomy conversion rate, while increasing the rate of successful sublobar resection of ground glass nodules (GGNs) via video-assisted thoracoscopic surgery (VATS). In this study, we compared the clinical efficacies of presurgical CT-guided hook-wire and indocyanine green (IG)-based localization of GGNs. METHODS Between January 2018 and December 2021, we recruited 86 patients who underwent CT-guided hook-wire or IG-based GGN localization before VATS resection in our hospital, and compared the clinical efficiency and safety of both techniques. RESULTS A total of 38 patients with 39 GGNs were included in the hook-wire group, whereas 48 patients with 50 GGNs were included in the IG group. There were no significant disparities in the baseline data between the two groups of patients. According to our investigation, the technical success rates of CT-based hook-wire- and IG-based localization procedures were 97.4% and 100%, respectively (P = 1.000). Moreover, the significantly longer localization duration (15.3 ± 6.3 min vs. 11.2 ± 5.3 min, P = 0.002) and higher visual analog scale (4.5 ± 0.6 vs. 3.0 ± 0.5, P = 0.001) were observed in the hook-wire patients, than in the IG patients. Occurrence of pneumothorax was significantly higher in hook-wire patients (27.3% vs. 6.3%, P = 0.048). Lung hemorrhage seemed higher in hook-wire patients (28.9% vs. 12.5%, P = 0.057) but did not reach statistical significance. Lastly, the technical success rates of VATS sublobar resection were 97.4% and 100% in hook-wire and IG patients, respectively (P = 1.000). CONCLUSIONS Both hook-wire- and IG-based localization methods can effectively identified GGNs before VATS resection. Furthermore, IG-based localization resulted in fewer complications, lower pain scores, and a shorter duration of localization.

Abstract
BACKGROUND The possibility of coil dislocation in computed tomography (CT)-guided microcoil localization of superficial pulmonary nodules is relatively high. The aim of the study is to investigate the outcomes of deeper localization technique during CT-guided microcoil localization of superficial pulmonary nodules before video-assisted thoracoscopic surgery (VATS). METHODS Fifty-seven identified superficial pulmonary nodules (nodule-pleural distance ≤ 1 cm on CT image) from 51 consecutive patients underwent CT-guided microcoil localization, and subsequent VATSs were included. The rate of technical success, complications, and excised lung volume were compared between deeper localization technique group and conventional localization technique group. RESULTS The technical success rate of the localization procedure was 100% (25/25) in the deeper localization group and 81.3% (26/32) in the conventional localization group (p = 0.030). Excluding one case of lobectomy, the excised lung volume in the deeper localization group and the conventional localization group was 39.3 ± 23.5 and 37.2 ± 16.2 cm3, respectively (p = 0.684). The incidence of pneumothorax was similar between the deeper localization group and the conventional localization group (24.0 vs. 21.9%, respectively, p = 0.850). The incidence of intrapulmonary hemorrhage in the deeper localization group was higher (16.0%) than that in the conventional localization group (6.3%), but the difference was not statistically significant (p = 0.388). CONCLUSION CT-guided microcoil localization of superficial pulmonary nodules prior to VATS using a deeper localization technique is feasible. Deeper localization technique reduced the occurrence of dislocation but did not increase excised lung volume.

Abstract
Objective The incidence of sub-centimeter pulmonary nodules has been increasing along with the use of low-dose computed tomography (LDCT) as a screening tool for early lung cancer detection. In our institution, pulmonary nodule computed tomography-guided localization (PNCL) is performed preoperatively with the laser angle guided assembly (LAGA), an angle reference device. This study aims to investigate the efficacy of postgraduate education in a phantom simulation of PNCL, with or without LAGA. Setting design This prospective study was conducted in an academic hospital in Taiwan. Seven thoracic surgery residents and three experienced senior physicians were recruited to perform PNCL using a phantom simulation, with or without LAGA, for five nodules each and complete a questionnaire. Performance data were collected. χ2 tests, Mann-Whitney U test, univariate and multivariate linear regression were used for statistical analyses. Results The confidence level increased from median 7[range 1, 9] to 8, range [6,9] (p = 0.001) before and after the simulation education course. The scores of enhanced PNCL ability and course satisfaction were as high as 8 [5,9], and 9 [7,9]. LAGA enabled broader puncture angles (with 27.5° [0°,80°]; without 14° [0°, 80°], p = 0.003), a lower puncture frequency (with 1 [1,4]; without 2 [1,5], p < 0.001), and a smaller angle deviation (with 3°[ 0°,8°]; without 5°[ 0°,19°], p = 0.002). Pleural depth in millimeters was associated with increased puncture frequency (0.019[0,010,0.028]) and procedure time (0.071'[ 0.018,0.123']. The PNCL-experienced physicians performed the procedure in less time (-2.854'[-4.646',1.061']. The traverse direction toward the mediastinum diminished the frequency (toward 1[ 1,3]; away 1 [1,5], p = 0.003) and time (toward 7.5'[2',18]'; away 9'[ 3',31'], p = 0.027). The learning curve did not improve procedure performance after ten PNCL simulation rounds. Conclusions The phantom PNCL simulation education course increased the confidence level, enhanced residents' skill acquisition, and promoted learning satisfaction. The angle reference device helped improve the outcomes of the puncture frequency and reduced angle deviation.

Abstract
Abstract
Background
Preoperative computed tomography (CT)-guided localization has been used to guide the video-assisted thoracoscopic surgery (VATS) sublobar (wedge or segmental) resection for pulmonary nodules (PNs). We aimed to assess the relative efficacy and safety of CT-guided methylene blue (MB)- and coil-based approaches to the preoperative localization of multiple PNs (MPNs).
Methods
Between January 2015 and December 2020, 31 total cases suffering from MPNs at our hospital underwent CT-guided localization and subsequent VATS resection in our hospital, of whom 15 and 16 respectively underwent MB localization (MBL) and coil localization (CL). The clinical effectiveness and complication rates were compared between 2 groups.
Results
The PN- and patient-based technical success rates in the MBL group were both 100%, whereas in the CL group they were 97.2% (35/36) and 93.8% (15/16), respectively, with no substantial discrepancies between groups. Patients in the MBL group illustrated a substantially shorter CT-guided localization duration compared with the CL group (18 min vs. 29.5 min, P < 0.001). Pneumothorax rates (P = 1.000) and lung hemorrhage (P = 1.000) were comparable in both groups. In the MBL and CL groups, the median interval between localization and VATS was 1 h and 15.5 h, respectively (P < 0.001). One-stage VATS sublobar resection of the target nodules was successfully performed in all patients from both groups.
Conclusion
Both CT-guided MBL and CL can be readily and safely utilized for preoperative localization in individuals who had MPNs, with MBL being correlated with a shorter localization duration compared with CL.

Abstract
PURPOSE To compare the clinical efficacy of computed tomography (CT)-guided localization needle and coil insertion as approaches to preoperative lung nodule (LN) localization. MATERIAL AND METHODS Between January 2018 and December 2019, 52 patients awaiting video-assisted thoracoscopic surgery (VATS) resection underwent CT-guided coil insertion to facilitate LN localization. Additionally, 41 patients underwent CT-guided localization needle insertion between January and June 2021. RESULTS In total, 62 and 54 LNs were localized in 52 and 41 patients in the coil and localization needle groups, respectively, with respective technical localization success rates of 96.8% and 100% (p = .498). The localization needle group exhibited a significantly shorter duration of localization relative to the coil group (p < .001), whereas comparable rates of pneumothorax (p = .918) and hemorrhage (p = .712) were evident in these groups. VATS-guided LN resection procedures achieved 100% technical success rates in both groups, and there were no significant differences between groups with respect to the type of resection (p = .113) or the mean duration of VATS (p = .778). CONCLUSION Coil- and localization needle-based approaches can be successfully used for LN localization prior to VATS resection, with localization needle insertion being associated with a shorter duration of localization.

Abstract
Background Video-assisted thoracoscopic surgery (VATS) is an emerging technology in minimally invasive surgery, which has become recognized as standard treatments for early-stage lung cancer. Microcoil localization is considered to be a safe and effective way of preoperative localization, and is essential to facilitate VATS wedge-resection for lung nodules. Case presentation Here we report a rare case of a 28-year-old female who developed hemorrhagic shock caused by delayed pneumothorax after preoperative computed tomography (CT)-guided microcoil localization. The thoracic CT revealed hydropneumothorax in the right thoracic cavity at 10 h after microcoil localization, and the patient later had significant decreased hemoglobin level (87 g/L). Emergency thoracoscopic exploration demonstrated that the hemorrhagic shock was induced by delayed pneumothorax, which led to the fracture of an adhesive pleura cord and an aberrant vessel. Electrocoagulation hemostasis was then performed for the fractured vessel and the patient gradually recovered from the hypovolemic shock. Conclusions Microcoil localization is a relatively safe and effective way of preoperative localization of lung nodules, however, hemorrhagic shock could be induced by rupture of pleural aberrant vessels subsequent to puncture related pneumothorax. Shorten the time interval between localization and thoracoscopic surgery, extend the monitoring time after localization might help to reduce the risk of these complications.

Abstract
Background Iatrogenic pneumothorax is the most frequent complication in preoperative CT‐guided localization (POCTGL) of lung nodules. We aimed to determine the predictive factors of iatrogenic pneumothorax. Methods We retrospectively analyzed data of consecutive POCTGL procedures in patients who received video‐assisted thoracoscopic surgery (VATS) at our hospital between May 2015 and October 2019. All of our patients utilized laser angle guide assembly to aid in the localization procedures. Results In 610 consecutive POCTGL procedures, 40 (6.6%) patients developed iatrogenic pneumothorax, and complications occurred in 8.5%. Univariate analyses revealed that puncture frequency, male gender, puncture depth, left decubitus position, and nodule near fissure were factors associated with pneumothorax, while multivariate analysis showed that only male gender (odds ratio 3.58, p = 0.012) and puncture frequency (odds ratio 2.39/time, p = 0.0004) determined development of pneumothorax. Further collective analysis on puncture frequency revealed that tumor in a difficult zone (1.33 ± 0.71 vs. 1.19 ± 0.45, p = 0.002), especially adjacent to the mediastinum (1.41 ± 0.75 vs. 1.21 ± 0.52, p = 0.002), angle difference of plan‐to‐practice (r = 0.209, p = < 0.001), depth to skin (r = 0.152, p < 0.001), and depth to pleura (r = 0.164, p < 0.001) were factors related to increased puncture frequency in univariate analyses. Only angle difference of plan‐to‐practice was associated in multivariate analysis (odds ratio: 1.158, p = 0.008). Conclusions Puncture frequency was the key factor in the development of iatrogenic pneumothorax from POCTGL. Other associated factors, especially angle difference, may have affected the puncture frequency and subsequently have some influence on the incidence of iatrogenic pneumothorax.

Abstract
Background Stage I non-small-cell lung cancer (NSCLC) can be treated by both ablation and sublobar resection (SR). This meta-analysis was therefore designed to better compare the relative safety and efficacy of these two approaches to treating stage I NSCLC. Materials and methods Relevant studies published through November 2020 in the Cochrane Library, Embase, and PubMed databases were identified for analyses which were conducted with RevMan v5.3. Results In total, 816 potentially relevant articles were identified, of which 8 were ultimately included in the final meta-analysis. Patients in the SR group exhibited a signficantly lower pooled local recurrence (LR) rate (5.0% vs. 25.4%, P < 0.0001), although pooled distant recurrence (DR) rates were similar in both groups (25.7% vs. 23.1%, P = 0.75). The pooled hazard ratio (HR) for overall survival (OS) (HR: 1.23; 95% CI: 1.13–1.33, P < 0.00001), progression-free survival (PFS) (HR: 1.34; 95% CI: 1.15–1.55, P = 0.0002), and cancer-specific survival (HR: 1.39; 95% CI: 1.15–1.70, P = 0.0009) all indicated better survival outcomes among patients that underwent HR treatment, while pooled complication rates were similar in both groups (27.7% vs. 43.8%, P = 0.27). Patients that underwent ablation exhibited significantly shorter pooled post-operative hospitalization relative to those in the SR group (MD: 5.93; 95% CI: 0.78–11.07, P = 0.02). No evidence of publication bias was detected through funnel plot analyses. Conclusions SR treatment of stage I NSCLC patients was associated with a lower LR rate and longer survival as compared to ablation.

Abstract
Introduction Preoperative computed tomography (CT)-guided localization is commonly employed to facilitate video-assisted thoracoscopic surgery (VATS)-guided diagnostic wedge resection of pulmonary nodules (PNs). Aim The present meta-analysis was conducted with the goal of better evaluating the feasibility, safety, and clinical efficacy of preoperative CT-guided localization for multiple PNs (MPNs). Material and methods PubMed, Embase, and the Cochrane Library databases were reviewed in order to identify all relevant studies published as of June 2020. Random effects modeling was then used to evaluate the pooled data. The meta-analysis was conducted using Stata v12.0 software. Results Eight relevant studies were identified for inclusion in the present meta-analysis. In total, 345 patients with 799 PNs were treated with preoperative CT-guided localization and subsequent wedge resection. The overall pooled technical success rate based on the nodules and patients was calculated to be 97% (95% confidence interval (CI): 0.94-0.99) and 92% (95% CI: 0.86-0.97), respectively. The overall pooled incidence rate of complications was calculated to be 40% (95% CI: 0.16-0.63). Significant heterogeneity was observed among the studies for all the parameters described above (I2 = 74.5%, 77.7%, and 96.3%, respectively). No significant differences were detected in the technical success of localization and incidence of complications between coil and hook-wire groups. The risk of publication bias in the reporting of technical success rate of localization based on both nodules and patients was found to be high (p < 0.001 and < 0.001, respectively). Conclusions Preoperative CT-guided localization may be effective in guiding VATS-guided wedge resection in patients with MPNs.

Abstract
We describe the clinical efficacy of coil localization (CL) assisted video-assisted thoracoscopic surgery (VATS) wedge resection (WR) for pulmonary nodules (PNs) in patients having a history of malignancy.In a total of 16 patients having PNs and malignant history, treatment was carried out using computed tomography (CT)-guided CL and subsequent VATS-guided WR procedures from November 2015 to December 2019. Technical success of CL, WR, and long-term outcomes was analyzed.A total of 21 PNs were localized (1.3 PNs per patient). A 100% technical success rate was achieved in this study for CT-guided CL. Each PN was localized with 1 coil. Two and 2 patients experienced pneumothorax and hemoptysis, respectively. VATS-guided WR also achieved a 100% technical success rate. Additional lobectomy was performed in 2 patients due to the invasive adenocarcinoma. The final diagnoses of these 21 PNs were adenocarcinoma (T1N0M0, n = 8), adenocarcinoma in situ (n = 2), pre-cancerosis (n = 1), metastasis (n = 2), and benign (n = 8). All patients underwent CT follow-up for 6 to 48 months. All patients were alive during the follow-up. The cumulative 6-, 12, and 24-month disease-free survival rates were 100%, 92.9%, and 47.3%, respectively. The median disease-free survival was 27.9 months.Pre-operative CT-guided CL can be safely and conveniently used to facilitate a high success rate of VATS-guided WR for PNs in patients with a malignant history. Among the PNs in patients with malignant history, primary lung cancer also occupied approximately half of the PNs.

Abstract
Introduction Lung nodules (LNs) are often identified in at-risk patients via low-dose computed tomography (CT) approaches. Sub-centimeter (≤ 1 cm) LNs (SCLNs) are particularly difficult for surgeons and pathologists to accurately treat and diagnose. Aim To evaluate the clinical efficacy of preoperative CT-guided coil localization for SCLNs. Material and methods Between January 2015 and December 2019, consecutive patients at our hospital with SCLNs underwent CT-guided coil localization followed by video-assisted thoracoscopic surgery (VATS). We then assessed rates of technical success corresponding to the localization and VATS-guided wedge resection procedures and measured rates of localization-related complications. Results In total, 52 patients were analyzed in this study, with 66 total SCLNs being localized with one coil each. CT-guided coil localization achieved a 93.9% (62/66) technical success rate, and a mean duration of 15.2 ±4.5 minutes. Following coil localization, 6 (11.5%) patients experienced pneumothorax and 4 (7.7%) patients suffered hemoptysis, with 1 patient requiring the insertion of a chest tube to alleviate pneumothorax. VATS-guided wedge resection was associated with a 100% technical success rate, and no patients needed to undergo conversion to thoracotomy. One-stage VATS-guided wedge resection was conducted in the 12 patients with multiple SCLNs. The mean VATS duration was 128.9 ±66.7 minutes, and mean blood loss associated with this procedure was 83.0 ±67.7 ml. Conclusions Preoperative CT-guided coil localization can safely and effectively achieve high rates of success when conducting the diagnostic VATS wedge resection of SCLNs.

Zhou C, Liu XB, Gan XJ, Li X. Calcification sign for prediction of benignity in pulmonary nodules: A meta-analysis. THE CLINICAL RESPIRATORY JOURNAL 2021; 15:1073-1080. [PMID: 34142452 DOI: 10.1111/crj.13410] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 04/13/2021] [Accepted: 06/08/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND The calcification sign assessed by computed tomography appears to be a potential marker for benignities among patients diagnosed with pulmonary nodules (PNs). The following meta-analysis has been purposefully designed to figure-out the diagnostic value of the calcification signature as a way of identifying benignities from PNs. METHODS Cochrane Library, Embase and PubMed were considered as a reference to obtain the required data from January 2000 until October 2020. Stata v12.0 was used as a standard tool for statistical assessment. RESULTS Eleven retrospective studies were assessed via this meta-analysis, which included 6136 PNs (1827 benign and 4309 malignant). The pooled diagnostic odd ratios, positive likelihood ratio (PLR), negative likelihood ratio (NLR), sensitivity and specificity were 6.79, 6.06, 0.89, 13% and 98%, respectively. The value obtained for the area under the curve was 0.65, showing moderate overall diagnostic accuracy. A significant heterogeneity was found while calculating the pooled sensitivity (I2 = 85.5%), specificity (I2 = 75.0%), PLR (I2 = 59.0%), NLR (I2 = 79.5%) and DOR (I2 = 100.0%) in the current analysis. Sub-group analyses presented better PLR and specificity values for the study with a sample size ≥ 400. Deeks' funnel plot asymmetry test detected no potential evidence of significant publication bias (p = 0.091). CONCLUSIONS Calcification signs have been identified as moderate regulators corresponding to overall diagnostic performance (via marking a distinct differentiation between malignant and benign) for PNs. However, the manifestation of the calcification sign had a good directive property for benign PNs.

Abstract
Purpose: To retrospectively analyze the incidence and predictors of complications related to hookwire localization in patients with single and multiple nodules, and to evaluate the usefulness of a single-stage surgical method of single hookwire localization combined with video-assisted thoracoscopic surgery (VATS) in synchronous multiple pulmonary nodules (SMPNs). Methods: A total of 200 patients who underwent computed tomography (CT)-guided hookwire localization and subsequent VATS resection were enrolled in this study. For each patient, only 1 indeterminate nodule was implanted with a hookwire. There were 145 patients in the single-nodule group (Group S) and 55 in the multiple-nodule group (Group M). Univariate and binary logistic regression analyses were used to assess incidence and predictors of complications associated with hookwire localization. Results: The technical success rate of hookwire implantation was 97.5%. The incidence of pneumothorax and hookwire dislodgement was 17.0% and 2.5%, respectively. Binary logistic regression analysis showed that 1 transpleural puncture through the pleura (odds ratio [OR] = 0.433, P = .033) was the only independent protective factor for pneumothorax, and pneumothorax (OR = 26.114, P < .01) was the only independent risk factor for dislodgement. The volume of blood loss during VATS was significantly higher in group M than in group S, and the time of postoperative hospitalization was significantly longer in group M than in group S. About 44 patients in group M with additional 58 nodules without localization had undergone direct surgical resection simultaneously, and bilateral surgery was performed in 13 patients (29.5%). The intrathoracic recurrence rate was 4.8% during follow-up CT. Conclusion: Single-stage surgery via an approach of single hookwire localization combined with VATS is feasible and safe for SMPNs.

Abstract
Background: Preoperative computed tomography (CT)-guided coil localization can increase the technical success of video-assisted thoracoscopic surgery (VATS)-guided diagnostic wedge resection of lung nodules relative to cases treated without localization. When multiple lung nodules (MLNs) are to be resected, preoperative localization for each lung nodule is required. The aim of this study was to explore the feasibility, safety, and clinical efficacy of preoperative CT-guided coil localization of MLNs. Methods: Between November 2015 and July 2019, 31 patients with MLNs were assessed via CT-guided coil localization followed by VATS-guided wedge resection. Rates of technical success for both the localization and wedge resection procedures, as well as data pertaining to patient complication rates and long-term outcomes were recorded and assessed. Results: In total, 68 nodules (average of 2.2 nodules/patient) were localized and resected using this approach. Nodules were unilateral and bilateral in 23 and 8 patients, respectively. The rate of CT-guided coil localization technical success for these nodules was 98.5% (67/68), with a technical success rate of single-stage coil localization on a per-patient basis of 96.8% (30/31). Following localization, asymptomatic pneumothorax occurred in four patients (12.9%). The wedge resection technical success rate was 100%. Mean VATS operative time was 167.3 ± 75.2 min, with a mean blood loss of 92.6 ± 61.5 ml. Patients were followed between 3 and 46 months (median: 24 months), with no evidence of new nodules, distant metastases, or postoperative complications in any patients. Conclusion: Preoperative CT-guided multiple coil localization can be easily and safely used to guide single-stage VATS diagnostic wedge resection in patients with MLNs.

Abstract
BACKGROUND Preoperative computed tomography (CT)-guided coil localization (CL) is commonly used to facilitate video-assisted thoracoscopic surgery (VATS)-guided diagnostic wedge resection (WR) of pulmonary nodules (PNs). When a scapular-blocked PN (SBPN) is localized, the trans-scapular CL (TSCL) is commonly performed. In this study, we investigated the safety, feasibility, and clinical efficacy of preoperative CT-guided TSCL for SBPNs. MATERIALS AND METHODS From January 2014 to September 2020, a total of 152 patients with PNs underwent CT-guided CL prior to VATS-guided WR. Of these patients, 14 had SBPNs and underwent the TSCL procedure. RESULTS A total of 14 SBPNs were localized in the 14 patients. The mean diameter of the 14 SBPNs was 7.4 ± 2.4 mm. The technical success rate of the scapula puncture was 100%. No complications occurred near the scapula. The technical success rate of CL was 92.9%. One coil dropped off when performing the VATS procedure. The mean duration of the TSCL was 14.2 ± 2.7 min. Two patients (14.3%) developed asymptomatic pneumothorax after TSCL. The technical success rate of VATS-guided WR was 92.9%. The patient who experienced technical failure of TSCL directly underwent lobectomy. The mean duration of the VATS was 90.0 ± 42.4 min and the mean blood loss was 62.9 ± 37.2 ml. The final diagnoses of the 14 SBPNs included invasive adenocarcinoma (n = 4), adenocarcinoma in situ (n = 9), and benign disease (n = 1). CONCLUSIONS Preoperative CT-guided TSCL is a safe and simple procedure that can facilitate high success rates of VATS-guided WR of SBPNs.

Abstract
To evaluate the clinical efficiency, feasibility, and safety of computed tomography (CT)-guided trans-scapular coil localization (TSCL) approach to treating scapula-blocked pulmonary nodules (SBPNs).In total, 105 patients with pulmonary nodules underwent CT-guided CL and subsequent video-assisted thoracoscopic surgery (VATS)-guided wedge resection (WR) between January 2016 and July 2020. Six of these patients (5.7%) had SBPNs that led them to undergo CT-guided TSCL. Rates of technical success and localization-related complications were then recorded and analyzed.CT-guided TSCL was associated with a 100% technical success rate, with one coil being placed per patient. The median CT-guided TSCL duration was 15 min. No patients experienced any complications associated with this procedure, and subsequent VATS-guided WR of SBPNs was 100% technically successful. In two patients with invasive adenocarcinoma, additional lobectomy was performed. Median VATS duration and intraoperative blood loss were 120 min and 150 mL, respectively.In summary, these results indicate that CT-guided TSCL could be easily and safely implemented to achieve high success rate when performing the VATS-guided WR of SBPNs.

Abstract
PURPOSE To investigate the clinical efficacy, feasibility, and safety of the preoperative computed tomography (CT)-guided coil localization (CL) approach for scapula-blocked lung nodules (SBLNs). MATERIAL AND METHODS A total of 123 patients with LNs were treated via CT-guided CL and subsequent VATS-guided wedge resection from January 2015 to June 2020. Of these patients, 12 (9.8%) exhibited SBLNs and underwent CT-guided CL. Technical success of localization and video-assisted thoracoscopic surgery (VATS)-guided wedge resection, and localization-related complications were recorded and analyzed. RESULTS The technical success rate of CT-guided CL was 100%. Each patient was placed with one coil. The mean duration of CT-guided CL was 14.7 ± 2.7 min. One patient (8.3%) developed asymptomatic pneumothorax, which has not impacted the subsequent VATS procedure. Successful VATS-guided wedge resection of these SBLNs was achieved in all patients, with no instances of conversion to thoracotomy. Additional lobectomy was performed in three patients. The mean duration of the VATS procedure and blood loss were 143.8 ± 95.5 min and 110.0 ± 82.0 ml, respectively. CONCLUSIONS The approach of CT-guided CL could be safely and easily utilized to facilitate high rates of success when conducting the VATS-guided wedge resection of SBLNs.

Abstract
This study was designed to explore the safety, feasibility, and clinical efficacy of preoperative computed tomography (CT)-guided coil localization of sub-fissural lung nodules (LNs). A total of 105 LN patients underwent CT-guided coil localization followed by video-assisted thoracoscopic surgery (VATS)-guided wedge resection at our hospital from January 2016 to December 2019. Of these patients, 4 had sub-fissural LNs and were therefore subjected to trans-fissural coil localization procedures. We analyzed data pertaining to the coil localization and VATS procedures in these patients. A total of 4 coils were used to localize 4 LNs in 4 separate patients. One of these patients suffered from parenchymal hemorrhage around the needle path, while one other patient exhibited asymptomatic pneumothorax following coil localization. A thoracoscope was able to successfully visualize the coil tails in all of these patients. There were no instances of coils having been dislodged, and wedge resection was conducted with a 100% technical success rate in these patients. These 4 LNs were subsequently diagnosed as adenocarcinomas in situ (n = 3) and benign nodules (n = 1). CT-guided coil localization can be used to safely and easily localize sub-fissural LNs in patients scheduled to undergo VATS.

Abstract
BACKGROUND Preoperative computed tomography (CT)-guided localization has been shown to significantly improve lung nodule video-assisted thoracoscopic surgery (VATS)-based wedge resection technical success rates. However, at present, there was insufficient research regarding the optimal approaches to localization of these nodules prior to resection. We aimed to compare the relative clinical efficacy of preoperative CT-guided methylene blue and coil-based lung nodule localization. METHODS In total, 91 patients with lung nodules were subjected to either CT-guided methylene blue (n = 34) or coil (n = 57) localization and VATS resection from January 2014 to December 2018. We compared baseline data, localization-associated complication rates, as well as the technical success of localization and resection between these two groups of patients. RESULTS In total, 42 lung nodules in 34 patients underwent methylene blue localization, with associated localization and wedge resection technical success rates of 97.6 and 97.6%, respectively. A total of 71 lung nodules in 57 patients underwent coil localization, with associated localization and wedge resection technical success rates of 94.4 and 97.2%, respectively. There were no significant differences in technical success rates of localization or wedge resection between these groups (p = 0.416 and 1.000, respectively). The coil group sustained a longer duration between localization and VATS relative to the methylene blue group (13.2 vs. 2.5 hours, p = 0.003). CONCLUSION Both methylene blue and coil localization can be safely and effectively implemented for conducting the diagnostic wedge resection of lung nodules. The coil-based approach is compatible with a longer period of time between localization and VATS procedures.

Abstract
PURPOSE To compare the relative clinical efficacy of preoperative computed tomography (CT)-guided methylene-blue (MB) and coil localization for lung nodules (LNs). MATERIAL AND METHODS Between January 2013 and December 2018, a total of 89 patients with LNs underwent CT-guided MB or coil localization and subsequent video-assisted thoracoscopic surgery (VATS)-guided wedge resection in our hospital. We compared the technical success of localization and wedge resection between two groups. RESULTS In MB group, 47 LNs in 39 patients were localized, with successful localization and wedge resection rates of 97.9% and 97.9%, respectively. In the coil group, 64 LNs in 50 patients were localized, with successful localization and wedge resection rates of 96.9% and 96.9%, respectively. There were no significant differences in technical success rates of localization and wedge resection between the two groups (p = 1.000 and 1.000). The coil group sustained a longer duration between localization and VATS relative to the MB group (14.4 h vs. 1.6 h, p = .001). CONCLUSION Both MB and coil localization were safe and effective techniques to establish a high success rate of VATS-guided wedge resection for LNs. Relative to MB localization, coil localization might be compatible with a longer delay between localization and VATS.

ANZ J Surg 2019; 89:E514-E518. [PMID: 31578777 DOI: 10.1111/ans.15450] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2018] [Revised: 05/21/2019] [Accepted: 08/27/2019] [Indexed: 12/26/2022]
Abstract
BACKGROUND Wedge resection via video-assisted thoracoscopic surgery (VATS) is the best choice for the diagnosis of sub-solid lung nodules. Preoperative localization is utilized to increase the success rate of this procedure. We aimed to evaluate the effectiveness of preoperative coil localization in VATS wedge resection for sub-solid lung nodules. METHODS From October 2015 to August 2018, 42 patients with 55 sub-solid lung nodules underwent computed tomography-guided coil localization with subsequent VATS wedge resection in our centre. Data regarding visible coil rates, technical success of the wedge resection and pathological results were collected and analysed retrospectively. RESULTS A total of 55 sub-solid lung nodules were localized in 42 patients. Thirty-three patients had one nodule and nine patients had multiple nodules. Fifty-two coils (52/55, 94.5%) were visible during the VATS. The mean duration of each coil localization was 14.3 ± 4.8 min (range 7-40 min). Three patients (7%) experienced pneumothorax after coil localization. VATS wedge resection was successfully performed for 53 nodules (53/55, 96.4%). The remaining two nodules were treated directly with lobectomy. The nine patients who had multiple nodules underwent one-stage VATS wedge resection of all nodules. The mean duration of the VATS in the 42 patients was 159.3 ± 83.4 min (range 60-360 min) while the mean blood loss was 119.3 ± 115.3 mL (range 10-700 mL). CONCLUSION Preoperative computed tomography-guided coil localization is a safe and effective method to facilitate high success rates for diagnostic VATS wedge resection for sub-solid nodules.

Abstract
BACKGROUND The objective of this study was to evaluate the feasibility, safety, and clinical effectiveness of preoperative computed tomography (CT)-guided transfissural coil localization (TFCL) of subfissural lung nodules. METHODS Five patients with lung nodules who underwent CT-guided TFCL before video-assisted thoracoscopic surgery between November 2015 and December 2018 were included. Technical success rates of TFCL and wedge resection were assessed, as well complications and pathological results. RESULTS The technical success rate of TFCL was 100%. Two patients experienced parenchymal hemorrhage around the needle path, and two patients experienced asymptomatic pneumothorax after TFCL. The technical success rate of the wedge resection of lung nodules was also 100%. The pathological diagnoses of the five nodules were minimally invasive adenocarcinoma (n = 3), adenocarcinoma in situ (n = 1), and inflammatory nodule (n = 1). CONCLUSION CT-guided TFCL is a safe and effective method for the preoperative localization of subfissural lung nodules.

Uniportal VATS Coil-Assisted Resections for GGOs. JOURNAL OF ONCOLOGY 2019; 2019:5383086. [PMID: 31214259 PMCID: PMC6535831 DOI: 10.1155/2019/5383086] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/30/2018] [Revised: 03/11/2019] [Accepted: 04/30/2019] [Indexed: 01/15/2023]
Abstract
Backgrounds Although uniportal video-assisted thoracic surgery (VATS) theoretically allows the direct palpation of any zone of the lung through a small incision, sometimes it can be difficult to localize pure ground-glass opacities anyway. The aim of this study is to evaluate the usefulness and safety of preoperative computed tomography (CT)-guided microcoil localization of GGO nodules in patients undergoing uniportal VATS lung resection. Methods The clinical data and CT images of 30 consecutive patients (30 pulmonary nodules) who underwent preoperative CT-guided coil localization and subsequent uniportal VATS resection, from January 2017 to October 2018, were reviewed. Results All the CT-localization procedures have been performed with success (30/30) and the mean procedure time was 35±15 minutes. The mean size of the nodules was 15,53±6,72 mm, and the mean distance of the nodules from the pleural surface was 19,08±12,08 mm. Eleven nodules (36,7%) were pure ground-glass opacities and 19 (63,3%) were mixed ground-glass with a solid component of 50% or more. In 5 cases, the localization procedure was complicated by asymptomatic pneumothoraxes and in 1 case the pneumothorax required chest tube insertion. In any case a conversion to thoracotomy was avoided because all nodules were identified and resected through uniportal VATS. Conclusions Preoperative CT-guided coil localization seems to be a feasible, safe, and accurate procedure. It makes uniportal VATS an easy approach even for resecting small, deep, and impalpable nodules.

Abstract
Background Video-assisted thoracoscopic surgery (VATS) has been widely used for diagnostic wedge resection of lung nodules. When VATS is performed for multiple lung nodules, preoperative localization for each target nodule is required. In this study, we evaluated the clinical effectiveness of computed tomography (CT)-guided simultaneous coil localization in one-stage VATS wedge resection for multiple lung nodules. Methods Between November 2015 to March 2018, 19 patients with multiple target nodules underwent CT-guided simultaneous coil localization and one-stage VATS resection at our center. Data on the technical success of simultaneous localization and wedge resection, complications, and pathological results were collected. Results A total of 43 nodules were localized. The localization was successfully achieved in 42 of 43 nodules (97.7%). The technique of simultaneous localization was successfully achieved in 18 of 19 patients (94.7%). Fifteen patients underwent unilateral lung localization and four patients underwent bilateral lung localization. Three patients (15.8%) experienced asymptomatic pneumothorax after localization. All patients successfully underwent one-stage wedge resection for all target nodules. The mean duration of one-stage VATS procedure was 171.8 ± 84.0 min. The mean volume of blood loss was 94.2 ± 58.0 mL. Three patients experienced pleural effusion after VATS. During a follow-up of 6–31 months (median 18 months), no patient developed new lung nodules or distant metastasis. Conclusions Preoperative simultaneous coil implantation is a safe and simple method for localization of multiple lung nodules. Simultaneous coil localization could effectively guide a one-stage VATS diagnostic wedge resection procedure.
