ERCP (Endoscopic Retrograde Cholangiopancreatography) is an advanced endoscopic procedure used for the diagnosis and treatment of various conditions affecting the bile ducts and pancreatic canal. This method plays a critical role in the management of pathologies such as bile duct obstructions, tumors, strictures, and leaks.

The most common indication for the procedure is the presence of stones in the common bile duct. Stones migrating from the gallbladder can obstruct the common bile duct, leading to symptoms such as severe abdominal pain, nausea, vomiting, fever, and jaundice; they can even damage the pancreatic duct, causing pancreatitis. ERCP is used to remove these stones and relieve the obstruction.

Furthermore, ERCP is an effective method utilized in the diagnosis and palliative treatment of bile duct and pancreatic tumors, in dilating bile duct strictures, repairing bile leaks, and treating certain complicated pancreatic diseases.

ERCP is a specialized procedure that requires particular expertise and should only be performed by gastroenterology specialists who are experts in this field, in fully equipped centers with appropriate clinical conditions.
