[Surgical Strategy for Multiple Synchronous Primary Lung Cancer Showing Ground Glass Opacities:Percutaneous Preoperative Computed Tomography-guided Lipiodol Marking Followed by Video-assisted Thoracic Surgery].

From May 2006 to March 2018, a total of 30 patients with multiple ground glass opacities( GGO) lessor equal to 2.0 cm underwent percutaneous preoperative computed tomography (CT)-guided Lipiodolmarking and subsequent video-assisted thoracic surgery( VATS). There were 22 patients with 2 GGOs,6 patients with 3 GGOs, 1 patient with 4 GGOs, and 1 patient with 5 GGOs. Of the 71 CT-guided Lipiodolmarking procedures were successfully completed. All 71 Lipiodol spots were detected with C-armshapedfluoroscopy and completely resected. Pneumothorax was the most common complication andoccurred in 22 (73.3%) of 30 cases. There were severe complications in two (6.7%) cases of pneumothoraxrequiring chest tube placement and three( 10.0%) cases of bloody sputum. Of 30 cases multipleGGOs revealed 24 synchronous lung cancer (19 patients with double lung cancer, 3 patients with triplelung cancer, 1 patient with quadruple lung cancer, and 1 patient with quintuple lung cancer). PreoperativeCT-guided lipiodol marking and VATS resection is a safe and reliable method for synchronous multiplelung cancer showing GGO.
