Abstract
Background: Endoscopic ultrasound (EUS) has been used in the clinical arena for almost 35 years and it is now well-integrated in everyday hospital practice.
Method: We conducted a systematic review of the available English-language articles.
Objective: The purpose of this review is to summarize the relevant applications of operative EUS.
Results: More than 5000 scientific papers published in the literature have demonstrated its high accuracy for the diagnosis and staging of a variety of benign and malignant conditions. The main indications of operative EUS, both diagnostic and therapeutic, are related to its ability to combine ultrasound imaging and safe and effective needle insertion into lesions originating from the gut wall and from organs nearby. In addition, technologic advancements of echoendoscopes with a therapeutic working-channel have allowed to perform several EUS-guided interventions, i.e. celiac plexus neurolysis, drainage of fluid collections, drainage of dilated biliary and pancreatic ducts, and vascular interventions.
Keywords: Celiac plexus neurolysis, endoscopic ultrasound, EUS, EUS-guided drainage, fine needle aspiration, gallbladder drainage.
