Your doctor may choose to perform a cholangioscopy in the event that x-ray imaging from an ERCP is insufficient to make an adequate diagnosis, or therapeutic intervention requires direct visualization of the site.
Your doctor will insert a small tube called a duodenoscope into your mouth, down your esophagus and into your stomach and duodenum until it reaches the bile duct. Your doctor will then place a thin fiberoptic scope into the duodenoscope to the desired area of interest within the duct for direct visualization.
Depending on what your doctor finds, he or she may use perform other procedures such as taking a tissue sample (biopsy) to test for cancer or other diseases, or remove stones and debris(with electrohydraulic lithotripsy).
Potential complications with an ERCP may include but are not limited to: pancreatitis (inflammation of the pancreas), infection, bleeding and perforation of the duodenum.
