Abstract: E ndoscopic ultrasound (EUS) is a relatively new endoscopic technique that provides high-resolution imaging by its unique ability to differentiate the histological layers of the gastrointestinal tract wall, as well as periluminal structures (1-4).Refinement of fine-needle aspiration (FNA) techniques has allowed for tissue and fluid sampling for diagnosis and staging, with the aid of newer techniques such as molecular analysis.EUS-FNA has led to the development of novel therapeutic methods, because therapeutic agents can now be delivered with EUS guidance into targeted areas by fine-needle injection (FNI).The advent of larger accessory channels and needles with a larger diameter has facilitated histopathological diagnosis of biopsy specimens, and enables the endosonographer to provide therapies such as tissue ablation and chemotherapy for the treatment of various neoplasms.The aim of the present article is to review some recent advances in the therapeutic role of EUS.
