The doctor can take a biopsy during the test. They can also put in a stent to treat jaundice during an ERCP.
The doctor passes a thin, flexible tube called an endoscope down your throat. This goes down into your stomach and into the first part of the small bowel (duodenum).
You should not eat or drink anything for 6 hours before the procedure. This is so your stomach and duodenum are empty. The doctor or nurse will give you a sedative to make you feel relaxed and sleepy. They will also use a local anaesthetic spray to numb your throat. Sometimes, doctors do this test under general anaesthetic (while you are asleep).
Your doctor will look down the endoscope. This helps them find the openings where the bile duct and the pancreatic duct drain into the duodenum. They can inject a dye into these ducts that will show on x-rays. This helps them find any abnormalities or blockages.
If there are any abnormal areas, the doctor will take a biopsy. They will then send the biopsy to the laboratory to be examined under a microscope.
They may put a small brush down the endoscope and take biopsies from the tumour. They will then send the brush with the cells on it to a laboratory, to be tested for cancer.
