Computed tomography-guided localization of pulmonary nodules prior to thoracoscopic surgery

With the increasing awareness of physical examination, the detection rate of pulmonary nodules is gradually increasing. For pulmonary nodules recommended for management by video-assisted thoracic surgery (VATS), preoperative localization of the nodule is required if its location is difficult to determine intraoperatively by palpation. The computed tomography (CT)-guided preoperative localization technique is the most widely used method with low operational difficulty and high efficiency, which can include hook wire, microcoil, medical dye, medical surgical adhesive, combined application, and emerging localization techniques according to the material classification. Each method has its corresponding advantages and disadvantages, but there is still a lack of unified guidelines or standards for the selection of CT-guided preoperative localization methods in clinical practice. This review summarizes the operation precautions, advantages, and shortcomings of the above localization techniques in order to provide references for clinical application.

Automated summary

With the increasing awareness of physical examination, the detection rate of pulmonary nodules is gradually increasing. CT-guided preoperative localization technique is the most widely used method for managing pulmonary nodules recommended for VATS. However, there is a lack of unified guidelines for the selection of localization methods in clinical practice.
