Getting ready for ERCP: why, getting ready, the day of, and after
For anyone who has an ERCP (endoscopic retrograde cholangiopancreatography) coming up, or who is driving someone home from one. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK, part of the NIH) says ERCP combines upper GI endoscopy and x-rays to find and treat problems of the bile and pancreatic ducts, such as a duct blocked by a gallstone. This page passes on, by name, what NIDDK says: why doctors use it; your health, your medicines, and pregnancy; nothing to eat or drink before, and the ride home; what happens during the procedure; and recovery, results, the risks, and when to get care right away. It builds the words to say and the questions to ask, and prints a card for the fridge.
Right now
- Trouble breathing, chest pain, fainting, or vomiting a lot of blood? Call 911 (ours).
- After ERCP: bloody or black, tar-colored stool, fever, severe pain in your chest or belly, problems breathing, problems swallowing or throat pain that gets worse, or vomiting (above all if it is bloody or looks like coffee grounds)? NIDDK says to seek medical care right away.
- Not sure whether to stop a medicine, such as a blood thinner, before it? Ask the doctor who ordered the procedure. Do not stop or change a prescribed medicine on your own (ours).
- It is all too much, or you are thinking of ending your life? Call or text 988, any hour (ours).

This page and its wording were written with AI (Claude) for Scarlet Beast (our AI policy). No doctor or nurse has reviewed it. The facts were read on October 17, 2026 on NIDDK’s Endoscopic Retrograde Cholangiopancreatography (ERCP) page (NIH) and its Spanish version, both last reviewed in January 2024 and saying the same things (the Spanish page also calls the special dye a contrast medium); the cards also point to NIDDK’s Upper GI Endoscopy, Gallstones and Pancreatitis pages. The numbers (nothing to eat or drink for up to 8 hours; 2 to 6 hours after; clear liquids for 4 to 6 hours, sometimes 24 hours before solid food; problems in about 5% to 10% of procedures) are NIDDK’s. NIDDK gives no length for the procedure, so neither do we. Ours: 911 for trouble breathing, chest pain, fainting, or vomiting a lot of blood; asking ahead which medicines change, and never stopping one on your own; mentioning any past reaction to an x-ray dye; asking for the time to stop eating and the time to stop drinking; asking the center about your ride, and packing for a possible night; asking who tells you the results and by when; the card; 988 when it is too much; health centers when money is tight; and the order of the steps. What we left out: sedative and dye names, brands, doses, and clinical pages for providers. This page saves nothing and loads no trackers.
