“…The methylene blue dye localization of pulmonary nodules was first reported in 1994 (12), with high success rate and short procedure time via both transthoracic and endobronchial route under CT or fluoroscopic guidance (13,14). Although preoperative dye localization for lung nodules has been previously studied (10,11,13,(15)(16)(17)(18)(19), there was limited research focusing on the efficacy and feasibility (20). In the past, various CT-guided localization methods existed among different interventional radiologists in our hospital, resulting in unsteady, and inconsistent yield rate.…”

Background: Preoperative localization for small invisible and impalpable pulmonary nodules is important in single-port video-assisted thoracoscopic surgery (VATS). Localization of multiple pulmonary nodules during VATS resection remains challenging. The aim of our study is to elucidate the efficacy of preoperative CT-guided methylene blue localization of both single and multiple pulmonary nodules.Methods: Consecutive patients undergoing preoperative CT-guided methylene blue dye localization for lung nodules, followed by VATS resection, were retrospectively analyzed between January 2014 and November 2019. Chi-square tests, Fisher's exact test and independent T-test were used to compare variables between the groups. Logistic regression was used to identify risk factors for procedure-related complications.Results: A total of 388 patients, including 337 with single nodule and 51 with multiple nodules, were analyzed. The success rate of preoperative CT-guided methylene blue localization for both single and multiple pulmonary nodules were comparable as 98.8% (333/337) vs. 100% (108/108). The procedure time was longer (23.2 ± 9.4 vs. 7.6 ± 4.8 min, p < 0.001) and risk of pneumothorax was higher (47.1 vs. 25.5%, p = 0.002) in the multiple nodule group. The procedure time (OR 1.079; 95% CI = 1.041–1.118; p < 0.001) was an independent risk factor for pneumothorax. Nodule depth (OR 2.829; 95% CI = 1.259–6.356; p = 0.011) was an independent risk factor for pulmonary hemorrhage.Conclusions: Preoperative CT-guided methylene blue localization for both single and multiple pulmonary nodules is safe, feasible, and effective.

“…With low-dose CT screening, the diagnosis of early-lung cancer became possible (35,36). When it came to small, deeply located, or ground-glass characteristic lesions, preoperative CT-guided localization was effective to identify the tumors and estimate the resection margins (37,38). In this cohort, 4 patients had sub-centimeter lung cancer.…”

BackgroundGeneral anesthesia and tracheal intubation potentially pose a high risk to health care workers (HCWs) managing surgical patients during the coronavirus disease 2019 (COVID-19) pandemic. Non-intubated anesthesia is a rational way of managing patients undergoing thoracoscopic surgery that avoids tracheal intubation and minimizes the aerosols generated during airway instrumentation. The purpose of this study was to determine whether non-intubated anesthesia in combination with a face mask is safe and feasible in patients undergoing thoracoscopic surgery.MethodsA total of 18 patients who underwent non-intubated thoracoscopic surgery with a face mask during the perioperative period between March 9, 2020 and April 6, 2020 were included. The main outcomes were anesthetic management and postoperative results.ResultsThe 18 patients had a mean age of 64 years and a body mass index of 22.9 kg/m2. All patients wore a mask during induction of anesthesia and throughout surgery. Three patients underwent lobectomy, four segmentectomy, ten wedge resection, and one underwent anterior mediastinal tumor resection. No patient developed cough or vomiting during the perioperative period. All patients were transferred to the postoperative recovery unit within 15 min of the end of surgery (average 7.2 min). No patient required conversion to tracheal intubation or conversion to thoracotomy.ConclusionNon-intubated anesthesia with a mask was safe and feasible in patients undergoing thoracoscopic surgery. Avoidance of intubated general anesthesia and use of a lung separation device may reduce the risk to HCWs of contamination by airway secretions, thereby conserving personal protective equipment, especially during the COVID-19 pandemic.

“…Techniques include chest CT-guided localization with dye, hook wire, micro coil, and indocyanine green; electromagnetic navigation bronchoscopy localization; or localization in a hybrid operation theater. 29,30 Results from a propensity score-matched analysis comparing electromagnetic navigation-and CT-guided methods of percutaneous transthoracic localization revealed similar results. 31 The authors concluded that the two methods were comparable for the preoperative localization of small lung nodules before uniportal videoassisted thoracoscopic surgery.…”
