At Werndale Hospital, ERCP (Diagnostic) is performed using advanced endoscopic visualization, fluoroscopic imaging, and individualized diagnostic planning. Established in 1991, this accredited hospital in Carmarthen, United Kingdom has 19 beds and offers specialized hepatobiliary and pancreatic services.

ERCP (Diagnostic) may be used when doctors need detailed information about the biliary or pancreatic duct system that cannot be adequately obtained through routine imaging. During the procedure, an endoscope is passed through the upper digestive tract to the opening of the bile and pancreatic ducts. A contrast agent may then be introduced, allowing the ducts to be visualized under fluoroscopy. Depending on the findings, the same procedure may sometimes be used for therapeutic interventions such as stone removal or stent placement.
