“…The second CT scanning after the lung marking contributes to the verification of the positional relationship between the needle and target lesion without the necessity for digital palpation. A redo marking is also available for marking failure cases with this method [ 9 ]. In the present case, we could localize the submillimeter nodule without any procedural related morbidity.…”

“…Because both the marking procedure and surgery were completed under general anesthesia in the operating room as a single stage procedure, it would be beneficial to reduce the patients’ stress as compared to the traditional marking method. These results suggest that this method would be a feasible option for image-guided VATS for preoperative marking of non-palpable lung nodules especially in the peripheral region [ 9 ].…”

Highlights A submillimeter metastatic lung tumor was resected successfully by intraoperative marking using a mobile CT with a navigation system. This method is safer and might be more accurate than the traditional hook wire marking without the necessity of percutaneous lung puncture. It also reduced a patient’s stress because the whole procedure could be done at a single stage under general anesthesia.

“…These localization techniques can be categorized into four groups according to the materials used: -localization with metallic materials: hook-wire [30][31][32], microcoil or spiral coil [33,34], -localization with dye: methylene blue [35,36], India ink [37] or indigo carmine [38], -localization with contrast agents: lipiodol [38], barium [39], -radioguided occult lesion localization (ROLL) with radiotracers [40].…”

Optimal management for patients with pulmonary metastasis is still debated. True survival benefit from widely practiced pulmonary metastasectomy (PM) is yet to be proved from high-quality randomized controlled trials. The ideal surgical approach for PM is also not generally agreed. VATS offers enhanced recovery and superior functional outcomes but at the expense of less detection of lung nodules and higher possibility of narrow/positive resection margins. The subxiphoid uniportal VATS (uVATS) approach is an evolving new approach with potential advantages including simultaneous access to both lung fields, less pain and faster rehabilitation. These advantages make it a favorable approach for PM, particularly in the setting of bilateral metastases. However, its use is still limited to case reports of a small number of patients. There is room for improvements in subxiphoid uVATS due to reported technical challenges and limitations. Herein, we aim to publicize a comprehensive review of literature on applications of subxiphoid uVATS in PM.

“…At present, the commonly used pulmonary nodule localization methods include preoperative CT‐guided percutaneous lung puncture, 1 , 2 spring coil localization, 3 methylene blue localization, 4 X‐ray localization under thoracoscopy, 5 , 6 intraoperative ultrasonic localization, 7 , 8 intraoperative localization using infrared imaging, 9 , 10 biological glue injection, 11 , 12 , 13 , 14 , 15 and intraoperative fluorescence localization under electromagnetic navigation bronchoscopy electromagnetic navigational bronchoscopy (ENB)/virtual navigation bronchoscope (VNB), 16 , 17 , 18 , 19 and others. 20 Each localization method has its own advantages and disadvantages, but clinical work has demonstrated that intraoperative indocyanine green localization under ENB/VNB has more advantages for patients with multiple pulmonary nodules undergoing simultaneous surgery, especially for those undergoing bilateral lung surgery. Therefore, this study retrospectively analyzed the data of patients undergoing simultaneous surgery for multiple pulmonary nodules in our hospital between 2018 and 2022.…”

Background Accurate localization of pulmonary nodules is the main difficulty experienced in wedge resection. Commonly used localization methods have their own advantages and disadvantages. However, clinical work has demonstrated that intraoperative indocyanine green localization under electromagnetic navigation bronchoscopy/virtual navigation bronchoscopy (VNB) is more advantageous than conventional methods for patients with multiple pulmonary nodules undergoing simultaneous surgery, especially for those undergoing bilateral lung surgery. Methods Data of patients undergoing simultaneous surgery for multiple pulmonary nodules with preoperative methylene blue localization by computed tomography (CT)‐guided percutaneous lung puncture (methylene blue group) or intraoperative indocyanine green localization under VNB (virtual navigation group) were retrospectively analyzed. Patient characteristics, pulmonary nodule features, localization time, preoperative location time, location success rate, operation time, complication incidence, visceral pleural staining rate after localization, and pulmonary nodule primary resection success rate were compared between the two groups. Results The methylene blue and virtual navigation groups comprised 39 and 20 patients with 119 and 67 pulmonary nodules resected, respectively. Sex, age, number of pulmonary nodules resected simultaneously, unilateral/bilateral lung surgery, pulmonary nodule size, distance between pulmonary nodules and the visceral pleura, pulmonary nodule consolidation‐to‐tumor ratio, location of pulmonary nodules in the pulmonary lobe, postoperative pathology, visceral pleura staining rate, primary pulmonary nodule resection success rate, and surgical duration did not differ significantly between the groups ( p > 0.05). The localization time of the virtual navigation group was significantly shorter than that of the methylene blue group ( p < 0.05), regardless of unilateral or bilateral multiple nodules. In the methylene blue group, 25.64% (10/39) of patients presented complications, all of which were pneumothorax, whereas no complications were found in the virtual navigation group. Conclusions For patients with multiple pulmonary nodules undergoing simultaneous surgery, indocyanine green injection under VNB can achieve a similar effect on pulmonary nodule localization as classical methylene blue injection under CT‐guided percutaneous lung puncture, with shorter localization time and fewer complications.
