Direct Cholangioscopy with Standard Ultraslim Endoscopes

Abstract: Ninety percent of patients with intraductal biliary stones are successfully treated with sphincterotomy and subsequent stone extraction. However, technical difficulty increases with stone size and giant stones require fragmentation to facilitate endoscopic removal. For stones too large to be engaged in a basket for mechanical lithotripsy, laser and electrohydraulic lithotripsy have been proposed for stone fragmentation. Application of electrohydraulic lithotripsy (EHL) is best achieved under direct visualization during cholangioscopy, because shock waves can also injure normal tissue. We present the case of a patient who underwent direct cholangioscopy for EHL of a giant stone that could not be retrieved by endoscopic retrograde cholangiopancreatography (ERCP). This article is part of an expert video encyclopedia.
