Simultaneous Resection of Lung Cancer and Broken Guide Sheath Tip Using Radiofrequency Identification System

Wedge resection of lung cancer using a radiofrequency identification (RFID) marking system was first reported in 2020 and has been increasingly used since. The case described here involved a 67-year-old female patient with Parkinson's disease with an Eastern Cooperative Oncology Group performance status of 3. Chest computed tomography showed an irregular 21-mm nodule in the left lung S1+2, contacting the interlobar pleura. During bronchoscopic lung biopsy, the guide sheath tip was slipped into the end of the left B1+2ciiα. The broken tip was 15 mm ventrally to the nodule and was judged difficult to palpate intraoperatively because it was 20 mm from the visceral pleura. To obtain accurate positional information during surgery, an RFID tag was placed near the guide sheath tip on the mediastinal side of B1+2ciiβ. After localization using a detection probe, wedge pulmonary resection was performed including both the cancer nodule and guide sheath tip. In short, using an RFID marking system, we could accurately remove a broken guide sheath tip and a lung cancer nodule.
