Pdf Summary

Electromagnetic navigation bronchoscopy (ENB) is a technique used for accurately localizing lung nodules in thoracoscopic surgery. This study aimed to evaluate the procedural outcomes and learning curve of ENB-guided dye marking. The researchers retrospectively analyzed patients who underwent ENB-guided dye marking for small pulmonary nodules. The dye marking was performed at the nearest pleura, and the localized nodules were resected thoracoscopically. The success rate of nodule localization was 94.8%, with a mean ENB duration of 19.3 minutes. The duration of ENB showed a negative correlation over time, indicating a potential learning curve. Difficult cases were mainly found in specific lung segments. No ENB-related complications were observed. The study concluded that ENB allows for safe and accurate minimally invasive resection of small pulmonary nodules. However, certain lung segments required a longer ENB duration, suggesting the need for additional assistance, such as fluoroscopy or con-beam CT, to increase accuracy and overcome the learning curve.
