A comparative study of 4-hook anchor device with methylene blue for preoperative pulmonary nodule localization.

ABSTRACT:

Background

Accurate localization of small pulmonary nodules (SPNs) during video-assisted thoracoscopic surgery (VATS) is challenging due to the small size and deep location. Both the 4-hook wire technique and methylene blue are significant methods for preoperative localization of SPNs. This study aimed to compare the safety of both methods by monitoring and recording any surgery-related complications. Additionally, the effectiveness of both methods was compared by measuring the success rate of localization and the time required for both localization and resection of the nodules.

Methods

Patients who underwent computed tomography (CT)-guided lung nodule localization before VATS from May 2021 to April 2023 at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Unio
