Planting Seeds into the Lung: Image-Guided Percutaneous Localization to Guide Minimally Invasive Thoracic Surgery

Abstract

Image-guided localization materials are constantly evolving, providing options for the localization of small pulmonary nodules to guide minimally invasive thoracic surgery. Several preoperative methods have been developed to localize small pulmonary lesions prior to video-assisted thoracic surgery. These localization techniques can be categorized into 4 groups according to the materials used: localization with metallic materials (hook-wire, microcoil, or spiral coil), localization with dye (methylene blue or indigo carmine), localization with contrast agents (lipiodol, barium, or iodine contrast agents), and radiotracers (technetium-99m). However, the optimal localization method has not yet been established. In this review article, we discuss the various localization techniques and the advantages and disadvantages of localization techniques as well as the available safety and efficacy data on these techniques.

The Importance of Stromal Endometriosis in Thoracic Endometriosis

“…Similarly, thoracic lesions or nodules that are small or more distant from the pleural surface might not be easily detected by palpation or with endoscopic forceps [ 46 ]. Thus, preoperative localization of small pulmonary lesions with either metallic materials (e.g., hook wire), with dyes (e.g., methylene blue), with contrast agents (e.g., lipidiol), or radiotracers (technetium-88m) have shown a success rate of 90–100% [ 46 ].…”

These techniques resulted in higher successful VATS rates, shorter operation times, increased economic benefits [ 46 ], and possibly longer recurrence-free survival of superficial premalignant, minimally invasive, and small invasive lung cancers [ 47 ].…”

Computed Tomography-Guided Methylene Blue Localization: Single vs. Multiple Lung Nodules

“…The methylene blue dye localization of pulmonary nodules was first reported in 1994 (12), with high success rate and short procedure time via both transthoracic and endobronchial route under CT or fluoroscopic guidance (13,14). Although preoperative dye localization for lung nodules has been previously studied (10,11,13,(15)(16)(17)(18)(19), there was limited research focusing on the efficacy and feasibility (20). In the past, various CT-guided localization methods existed among different interventional radiologists in our hospital, resulting in unsteady, and inconsistent yield rate.…”

A Glimpse on Trends and Characteristics of Recent Articles Published in the Korean Journal of Radiology

“…Among them, radiofrequency ablation, thyroid imaging and intervention, liver imaging, and cardiovascular imaging contributed for six articles, respectively (46172429303147495069737481104109112114128129130131132133134135136137138139140141142143144145146). Top 10 KJR articles that had been read most in October 2019 included four articles on thyroid imaging or intervention and six practice guidelines or consensus statements (6216168697181126147148).…”
