ERCP is a special procedure that combines upper GI endoscopy and x-rays to check and treat issues in the bile and pancreatic ducts, like removing gallstones or putting in stents. Doctors use techniques such as slicing open a tiny part of the digestive system (endoscopic papillectomy), cutting a small opening in the muscle that controls bile flow (sphincterotomy), and widening the bile duct opening (endoscopic papillary balloon dilation) during ERCP to help with biliary interventions.
When it’s hard to get into the bile ducts, doctors have different ways like using dye to see better, guiding tools with short or long wires, and even doing precut cuts (precut papillotomy) to make access easier.
For really tough cases, they might do something called needle-knife pre-cut papillotomy or use advanced rendezvous methods through other procedures like PTC, laparoscopy, and EUS-guided techniques to manage biliary diseases after failed attempts.
ERCP can be tricky and carries risks which is why only skilled doctors perform it for both looking into problems as well as fixing them in the bile and pancreatic ducts. Ready to learn more? Keep reading!
