ENDOSCOPIC RETROGRADE CHOLANGIO PANCREATOGRAPHY (ERCP)
ERCP is a procedure done with the help of side viewing endoscope to diagnose conditions like CBD Stones, Cancers of the biliary tract and Worms of Biliary tract. During an ERCP, the gastroenterologist uses an endoscope, a long, thin, flexible tube, with, a light and camera at the end, through the esophagus, the stomach, and the first part of the small intestine, called the duodenum. Once the endoscope reaches the papilla, which is the opening of the common bile duct, the physician injects dye through these ducts, enabling X-rays to be taken and after this stones are removed from CBD. Metallic & plastic stents are put across the CBD to give palliative measures in cancers of biliary tract.
