Abstract
Despite the use of near-infrared thoracoscopy with intravenous indocyanine green, intraoperative assessment of the surgical margin for the resection of non-palpable tumors located near the intersegmental plane requires highly advanced surgical skill for the prevention of local recurrence. Because the demarcation line is limited to the pleural surface, to overcome uncertainty in tumor palpation for deeply located small-sized lesions, other supplemental localization techniques have been proposed. Here, we present a novel surgical technique using radiofrequency identification markers for intraoperative assessment of the lateral surgical margin in segmentectomy.
Highlights
Anatomical segmentectomy can achieve oncologic outcomes similar to lobectomy in small-sized lung cancer [1]
If insufficient surgical margins are expected on the basis of 3D simulation, the surgical plan should be changed from single segmentectomy to additional resection with adjacent subsegmentectomy [3]
To overcome uncertainty in tumor palpation, preoperative simulation using 3D-CT has been utilized for the measurement of margins between the tumor and planned resection line
Summary
Anatomical segmentectomy can achieve oncologic outcomes similar to lobectomy in small-sized lung cancer [1]. Instead of simplification of the surgical procedure in segmentectomy, the resection line should be adjusted to the tumor location [4]. We recently reported a novel surgical technique using radiofrequency identification (RFID) markers in wedge resection for determination of deep surgical margins [5, 6].
