Overview

Other imaging studies for cholangiocarcinoma include endoscopic retrograde cholangiopancreatography, endoscopic ultrasound, percutaneous transhepatic cholangiography, and MRCP.

Other Imaging Findings

Endoscopic retrograde cholangiopancreatography (ERCP)

While abdominal imaging can be useful in the diagnosis of cholangiocarcinoma, direct imaging of the bile duct is often necessary. Endoscopic retrograde cholangiopancreatography (ERCP) has been widely used for this purpose. Although ERCP is an invasive procedure with attendant risks, its advantages include:

  • Evaluating the bile duct
  • Obtaining a biopsy
  • Helping for plan surgery
  • Place a small tube (stent) into the bile duct to relieve a blockage caused by a tumor

Endoscopic Ultrasound

  • Performed at the time of ERCP
  • Increase the accuracy of the biopsy and yield information on lymph node invasion and operability [1]

Percutaneous Transhepatic Cholangiography (PTC)

  • Alternative technique for ERCP

Direct Cholangiography

  • Evaluation of the the biliary tree
  • Planning treatment as assessing for resectability

Magnetic resonance cholangiopancreatography (MRCP)
