EP02.03-017. Novel Intraoperative CT-Guided Marking Using O-Arm in Video-Assisted Thoracoscopic Surgery

Pdf Summary

This study examined the usefulness and safety of a novel intraoperative CT-guided marking method using the O-arm surgical imaging system in video-assisted thoracoscopic surgery (VATS) for identifying small lung tumors. The study included 30 patients who underwent the marking procedure, with a total of 39 lesions marked. The O-arm system provided 2D fluoroscopic imaging and 3D cone-beam CT imaging, allowing for accurate visualization of the tumor location. In all cases, the tumor could be detected by intraoperative CT scan using the O-arm system, and pathologic complete resection was achieved. Only one patient required additional resection due to insufficient margin. There were no complications related to the O-arm system marking. <br /><br />Compared to other percutaneous marking methods, the CT-guided marking using the O-arm system was found to be relatively easy and did not require preoperative marking procedures or CT scans. This allowed physicians and patients to be prepared for usual thoracic surgery. If the tumor could be detected during surgery through other means, the use of the O-arm system could easily be cancelled. The study concluded that the CT-guided marking with the O-arm system is a non-invasive, simple, and practical method for identifying and localizing lung tumors during VATS surgeries, with low radiation exposure. <br /><br />Overall, the study demonstrated the effectiveness and safety of using the O-arm system for intraoperative CT-guided marking in VATS surgeries, providing a potentially valuable tool for precise tumor localization and successful resection.
