@contentandwell ERCP is a day surgery. I have had mine to open a blocked bile duct. They place a stent into the duct to open and widen it. In the process your pancreas can be "disturbed" or jostled. This can result in pancreatitis which is excrutiatingly painful. I've had it 3 times now all resulting in long hospital stays to manage the pain. Also when you try to eat it causes more pain. So clear fluids are all I can handle. I haven't had a meal since early February.
