简要总结
This cohort study aims to investigate the clinical efficacy and safety of Hybrid APC for treatment of gastric low grade intramucosal neoplasia.
详细描述
This cohort study aims to investigate the clinical efficacy and safety of Hybrid APC for treatment of gastric low grade intramucosal neoplasia. Successful ablation is defined as no evidence of local recurrence at 12 months after HybridAPC upon follow up endoscopy. This is defined as absence of LGIN, HGIN and cancer in biopsies obtained at all locations during followup endoscopy.
