Comparison of Two Dye Marking Methods for Preoperative Localization of Pulmonary Nodules Guided by Electromagnetic Navigation Bronchoscopy.

ABSTRACT:

Background

The increasing detection of pulmonary nodules has made accurate preoperative localization clinically urgent. Although electromagnetic navigation bronchoscopy (ENB)-guided dye marking is effective, evidence is limited, and the optimal dye remains unclear. This study compared methylene blue (MB) and indocyanine green (ICG) to determine the more efficient option for pulmonary nodule localization.

Methods

A total of 101 patients who underwent preoperative ENB localization between 2015 and 2021 were included. Patients were divided into two groups according to the dye used (MB or ICG) for comparative analysis. The primary outcomes were localization success rate and ENB-related complications. Secondary outcomes included the impact of different dyes on operative efficienc
