Endoscopic retrograde cholangio pancreatography (ERCP) - series: Indication
|
Gallstones usually form in the gallbladder. Gallstones sometimes pass from the gallbladder into the common bile duct, and block the flow of bile into the duodenum. This can result in serious illness. Additionally, tumors of the pancreas and duodenum can block the bile duct, also preventing the flow of bile into the duodenum.
