CURRENT STATUS AND PERSPECTIVES ON INTERVENTIONAL ENDOSCOPIC ULTRASOUND(EUS)

Abstract

Interventional endoscopic ultrasound (EUS) is gaining acceptance as an effective method of managing a variety of conditions. EUS-guided fine-needle aspiration (EUS-FNA) has become a valuable tool for the diagnosis of lesions within the gastrointestinal tract and surrounding organs. It has proven to be an effective diagnostic method with high levels of accuracy and low complication rates. EUS-guided therapy can be categorized into 1) EUS-guided drainage, 2) EUS-guided celiac plexus block/neurolysis, and 3) others. More recently, EUS-guided gastrojejunostomy bypass for malignant gastric outlet obstruction has been established in the human setting. The possibility of interventional EUS has expanded the indications for EUS.
