    Background:
    In the thoracic surgery for non-palpable and invisible ground-glass opacity (GGO) lung nodules , various methods have been reported, such as needle sticking or infusion of roentgen non-permeable substances around the tumor under computed tomography (CT) guidance. However, there are serious problems such as air embolism and/or tumor dissemination into the thoracic cavity. Mobile computed tomography, O-arm Surgical Imaging System (Medtronic), can provide an image intraoperatively. In this study, we evaluated the usefulness of mobile computed tomography in thoracic surgery for the GGO lung nodules.
    
    Method:
    From December 2016 to May 2017, 3 patients with ground-glass opacity lung nodules were evaluated under video assisted thoracoscopic surgery using O-arm system. Before surgery, the patient was placed in lateral decubitus position in the CT room, and the skin directly above the tumor was marked with a skin marker. In the operation room, a port was made on the marked position, and a Naruke's thoraco cotton dyed with indigo carmine was introduced into the port to mark the visceral pleura just above the lesion. Then, the tumor-side lung was deflated, and the marked visceral pleura was grasped with non-traumatic forceps. Intraoperative CT imaging was reconstructed with O-arm, and the GGO lesion was comfirmed and resected under the guidance of positional relationship between the forceps and the tumor.
    
    Result:
    In all 3 patients, the tumor could be seen intraoperatively with computed tomography using the O-arm system, and resected properly. No complications were experienced in this study on the use of the O-arm system.
    
    Conclusion:
    The O-arm system could be a new strategy for the surgical treatment of non-palpable lung lesions.
