Pancreatitis is a serious condition caused by inflammation of the pancreas, an organ responsible for digestion and blood sugar regulation. Severe cases can lead to abdominal pain, digestive issues, and long-term complications. In such situations, ERCP plays a vital role in both diagnosis and treatment. This advanced procedure helps identify blockages, gallstones, duct narrowing, or other abnormalities affecting the pancreatic and bile ducts. ERCP also allows immediate therapeutic intervention, such as stone removal or stent placement, during the same procedure. As a minimally invasive technique, ERCP significantly improves the management of pancreatitis, while enhancing patient recovery and quality of life.
