Endoscopic Retrograde Cholangiopancreatography

After the major papilla is cannulated, contrast medium enters the bile duct or pancreatic duct and outlines the ductal system on fluoroscopic X-ray images. This creates a radiographic view that can help clinicians identify the location of a blockage, narrowing, or leak. Because imaging occurs during access to the ducts, treatment can follow within the same procedure when indicated.

The major papilla provides the point of access from the duodenum into the bile duct and pancreatic duct. Advancing the endoscope to this location allows clinicians to cannulate the relevant duct selectively before injecting contrast. Successful access is therefore central to both duct visualization and the use of therapeutic instruments for targeted treatment.

The procedure supports several targeted interventions after ductal access has been established. Stones can be removed, narrowed segments called strictures can be widened, and stents can be placed to support ductal drainage. These options allow the same endoscopic session to move beyond identifying an abnormality and directly address an obstruction or impaired duct passage.

ERCP combines direct access to the ducts with radiographic visualization, allowing clinicians to assess an abnormality and treat it in a focused manner. This is particularly relevant when a patient has biliary obstruction, a bile leak, or a selected pancreatic duct disorder requiring action. The resulting treatment may relieve obstruction and help guide subsequent clinical management.

The clinician advances an upper gastrointestinal endoscope through the digestive tract to the duodenum and locates the major papilla. The appropriate duct is then cannulated, contrast medium is injected, and fluoroscopic X-ray images are obtained. If the findings support treatment, instruments can be used during the same procedure to remove stones, widen strictures, or place stents.

ERCP is primarily used when disorders of the bile ducts or pancreatic duct require targeted evaluation or treatment. Common clinical situations supported by the procedure include biliary obstruction, bile leaks, and selected pancreatic disorders. Its role is especially important when ductal access can provide both radiographic information and an opportunity to relieve or manage the underlying problem.

Stent placement is one of the therapeutic options available after the relevant duct has been accessed and visualized. By placing a stent within a duct, clinicians can address a problem requiring supported passage, particularly in the setting of an obstruction or narrowed segment. The intervention can contribute to relieving obstruction and supplying information that guides further clinical management.

ERCP can show the radiographic appearance and location of abnormalities within the bile or pancreatic ducts while also allowing clinicians to respond to those findings. A detected stone, stricture, or leak may lead to a corresponding intervention, such as removal, widening, or stent placement. Thus, the procedure can connect ductal findings directly with a treatment plan.
