Endoscopic retrograde cholangiopancreatography (ERCP); with removal of foreign body(s) or stent(s) from biliary/pancreatic duct(s)

Endoscopic retrograde cholangiopancreatography (ERCP) is a specialized procedure that involves the use of an endoscope, a flexible tube equipped with a camera and light, to examine and treat conditions related to the biliary and pancreatic ducts. During this procedure, the endoscope is carefully passed through the esophagus and stomach, reaching the duodenum, which is the first part of the small intestine. The procedure specifically targets the ampulla of Vater, a critical junction where the pancreatic duct and the common bile duct converge. This area is also known as the duodenal papilla. Once the endoscope is in place, a smaller catheter is introduced through the endoscope to cannulate the ampulla of Vater, allowing for the injection of contrast material. This contrast agent is essential for visualizing the biliary system, including the common bile duct, gallbladder, and pancreas, as it enhances the clarity of images obtained during the procedure. Following the visualization, a guidewire is placed through the catheter to facilitate access to the site of any foreign body or stent that may need to be removed. The guidewire is then withdrawn, and a snare is introduced to capture and extract the foreign object or stent. After the removal, additional contrast is injected to reassess the biliary system for any potential abnormalities, such as strictures or filling defects, ensuring comprehensive evaluation and treatment of the condition.
