Modified Mediastinoscopy Using Thoracoscopic Optics for Invasive Staging of Non-Small Cell Lung Cancer in a Hospital in Lima, Peru
Keywords:
N2 disease, mediastinal staging, mediastinoscopy, non–small cell lung cancerAbstract
Introduction: In centers where video-mediastinoscopy (VAM) and endobronchial ultrasound (EBUS) are unavailable, surgery is essential for the diagnosis and staging of non-small cell lung cancer (NSCLC).Case report: We describe our initial experience with modified mediastinoscopy using thoracoscopic optics (MMTO) and its results in the invasive staging of NSCLC. We report a series of six cases with clinical stage IIb–IIIb NSCLC who underwent MMTO at the Hospital Nacional Guillermo Almenara Irigoyen (HNGAI) between March and June 2025. The surgical technique, clinical characteristics, intraoperative findings, and immediate outcomes are described. The technique allowed adequate access and visualization of lymph node stations 2R, 4R, 4L, and 7 in all cases, with no postoperative complications reported. Conclusion: MMTO is a safe and feasible alternative for invasive mediastinal staging in NSCLC in centers without access to VAM or EBUS.
