%0 Journal Article %T From a Diagnostic Tool to a Therapeutic Instrument: Interventional Endoscopic Ultrasound %A C. Roberto Simons-Linares %J Archive of "ACG Case Reports Journal". %D 2019 %R 10.14309/crj.0000000000000072 %X Endoscopic ultrasound (EUS) literature dates back to the 1980s, and the first report of its application in gastroenterology was published in the Lancet by Dimagno et al, entitled ˇ°Ultrasonic endoscope.ˇ±1 In its infancy, EUS was utilized for diagnostic imaging only, until the 1990s when an echoendoscope equipped with an accessory channel was introduced. Several EUS-guided interventions have been performed since the early 1990s, such as fine needle aspiration and celiac plexus neurolysis.2¨C5 In recent years, however, we have witnessed multiple new EUS-guided interventions, with many becoming the treatment of choice for multiple diseases. Moreover, because of its increasing use, several new devices have been developed (eg, lumen-apposing metal stents [LAMS], microbubble contrast agents for harmonic EUS) or adapted from other specialties (microcoils, hyaluronate, sclerosants, cardiac angioplasty balloon, or multiple interventional radiology wires) %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6650014/
