A Surgeon\u27s Guide for Various Lung Nodule Localization Techniques and the Newest Technologies.

Preoperative image-guided localization of lung nodules is necessary for successful intraoperative localization and resection. However, current localization techniques carry significant intraoperative disadvantages for surgeons. Articles were selected through multiple search engines using key search terms and reviewed to compare results, outcomes, advantages, limitations, and complications of various localization methods. Current methods utilize microcoils, hookwires, contrast media, dyes, cyanoacrylate, radiotracers, or fluorescence tracers, which are associated with many intraoperative disadvantages even when paired with other imaging modalities including computed tomography and bronchoscopy techniques. Novel technologies including robotic bronchoscopy, 4-hook anchor, SPiN Thoracic Navigation System, superDimension, Ion Endoluminal System, and the SCOUT system are reviewed including their advantages, which may change the future direction of minimal thoracoscopic surgery with potential to improve intraoperative accuracy and efficiency
