Hybrid APC Therapy in Early Central Lung Neoplasms

• HybridAPC is integrated with traditional APC and water-jet technique, which has been successfully applied for endoscopic treatment of mucosal lesions in GI, such as Barrett esophageal and lesions in colon. Submucosal injection of water jet can elevate superficial lesion, and then APC can be more effective in ablation of superficial tumor with a protection for muscular layer. The application of HybridAPC in respiratory intervention could theoretically protect cartilage, adventitia, reduce damage and formation of scare, and increase ablation energy to reach radical treatment. • High-frequency EBUS, could display the boundary between cartilage endomembrane and cartilage, in order to determine the depth of tumor.
