The procedure described in the question is endoscopic retrograde cholangiopancreatography (ERCP), where contrast media is introduced into the biliary and pancreatic ducts through an endoscope in the duodenum. This procedure is specifically used for evaluating obstructions, strictures, stone diseases, and pancreatic cancer. Endoscopic ultrasound (B) is a different procedure that uses high-frequency sound waves to produce images of the digestive tract and surrounding organs. Abdominal sonography (C) is a non-invasive imaging technique that uses sound waves to create images of the abdominal organs, and esophagogastroduodenoscopy (D) is a procedure used to examine the esophagus, stomach, and duodenum with an endoscope.
