ERCP is generally a low-risk procedure when performed by gastroenterology specialists experienced in the field. However, as with any medical intervention, some complications can rarely occur. Possible complications include pancreatitis (inflammation of the pancreas), cholangitis (inflammation of the bile duct), or cholecystitis (inflammation of the gallbladder). More serious, but very rare complications such as bleeding or perforation (puncture) can also occur after an incision (sphincterotomy) made to widen the bile duct. Therefore, the experience of the specialist performing the procedure and the appropriate equipment of the healthcare facility where the procedure will be carried out are of critical importance.
