Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems. Through the endoscope, the physician can see the inside of the stomach and duodenum, and inject radiographic contrast into the ducts in the biliary tree and pancreas so they can be seen on radiographs. ERCP is used primarily to diagnose and treat conditions of the bile ducts and main pancreatic duct,〔Adler DG, Baron TH, Davila RE, Egan J, Hirota WK, Leighton JA, Qureshi W, Rajan E, Zuckerman MJ, Fanelli R, Wheeler-Harbaugh J, Faigel DO; Standards of Practice Committee of American Society for Gastrointestinal Endoscopy.

ERCP can be performed for diagnostic and therapeutic reasons, although the development of safer and relatively non-invasive investigations such as magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasound has meant that ERCP is now rarely performed without therapeutic intent. ==Diagnostic== *Obstructive jaundice - This may be due to several causes *Chronic pancreatitis - a now controversial indication due to widespread availability of safer diagnostic modalities including endoscopic ultrasound, high-resolution CT, and MRI/MRCP *Gallstones with dilated bile ducts on ultrasonography *Bile duct tumors *Suspected injury to bile ducts either as a result of trauma or iatrogenic *Sphincter of Oddi dysfunction *Pancreatic tumors no longer represent a valid diagnostic indication for ERCP unless they cause bile duct obstruction and jaundice. Endoscopic ultrasound represents a safer and more accurate diagnostic alternative 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「endoscopic retrograde cholangiopancreatography」の詳細全文を読む スポンサード リンク
