Electromagnetic Navigation Bronchoscopy Triple Contrast Dye Marking for Lung Nodule Localization.

Area of Science:

• Thoracic Surgery
• Pulmonary Medicine
• Medical Imaging

Background:

• Localizing small pulmonary lesions for video-assisted thoracoscopic surgery (VATS) presents significant challenges.
• Electromagnetic navigation bronchoscopy (ENB) with dye marking, especially using cone beam computed tomography (CBCT) in a hybrid operating room (HOR), is an emerging technique for improved localization.
• Current ENB dye marking methods face difficulties in confirming dye injection and ensuring intraoperative visualization of the dye.

Purpose of the Study:

• To present a novel technique for electromagnetic navigation bronchoscopy (ENB) dye marking of lung nodules.
• To address the challenges of dye injection confirmation and intraoperative visualization in the hybrid operating room (HOR).
• To introduce the triple-contrast dye method for enhanced localization of pulmonary lesions.

Main Methods:

• Utilized electromagnetic navigation bronchoscopy (ENB) for precise localization of pulmonary nodules.
• Employed cone beam computed tomography (CBCT) within a hybrid operating room (HOR) setting.
• Developed and applied a novel triple-contrast dye method for marking lung nodules.

Main Results:

• The triple-contrast dye method was successfully implemented for ENB dye marking in the HOR.
• The technique aimed to enhance the confirmation of dye injection and intraoperative visualization.
• This approach addresses previously identified uncertainties in ENB-guided lesion localization.

Conclusions:

• The triple-contrast dye method offers a promising solution for ENB dye marking of lung nodules in the HOR.
• This technique has the potential to improve the reliability and efficacy of VATS procedures for small pulmonary lesions.
• Further evaluation is warranted to confirm the benefits of this novel approach in clinical practice.
