What is the most common complication following an endoscopic retrograde cholangiopancreatography (ERCP)?

• A. Infection
• B. Hemorrhage
• C. Pancreatitis
• D. Bowel perforation

Answer: (C)

Pancreatitis is indeed the most common complication following an endoscopic retrograde cholangiopancreatography (ERCP). The procedure involves cannulating the bile and/or pancreatic ducts, which can sometimes lead to inflammation of the pancreas. This complication occurs in about 3-5% of patients undergoing ERCP and can manifest with symptoms such as abdominal pain, nausea, and vomiting.

The risk factors for developing pancreatitis post-ERCP include the manipulation of the pancreatic duct, the presence of sphincter of Oddi dysfunction, and the injection of contrast material for imaging. While other complications can occur, such as infection, hemorrhage, or bowel perforation, they are less frequent compared to pancreatitis. Therefore, understanding the mechanism behind pancreatitis as a complication of ERCP is crucial for both prevention and management strategies in clinical practice.
