Bile-Duct Stone Removal under Direct Transnasal Cholangioscopy Using an Ultraslim Upper Endoscope

Abstract

The transnasal endoscopic examination using an ultraslim upper endoscope may be more comfortable and less stressful than the peroral approach. Transnasal endoscopic retrograde cholangiopancreatography (ERCP), endoscopic nasobiliary drainage, and direct peroral cholangioscopy using an ultraslim upper endoscope have recently been reported. An 82-year-old woman with a previous history of endoscopic sphincterotomy and stone removal was admitted with acute cholangitis. Instead of conventional ERCP, we performed direct transnasal cholangioscopy (TNC) using an ultraslim upper endoscope for biliary decompression and stone removal because of her unstable vital signs. Direct TNC using an ultraslim upper endoscope may be useful in selected patients with biliary disease. (Gut Liver 2010;4:428-429)
