title: Endoscopic and endosonography guided fine-needle aspiration.
abstract: Endoscopic ultrasound-guided fine-needle aspiration is emerging as the preferred technique for the cytologic diagnosis of various gastrointestinal lesions. This technique may not be routinely available, but there is still a role for endoscopic or endoscopic ultrasound-assisted fine-needle aspiration. This article provides an overview of the evolution of these various techniques and discusses the advantages, disadvantages, indications, and contraindications of each.
