Interventional endoscopy is a division of Gastroenterology that performs pancreatic and biliary endoscopy and advanced staging of digestive tumors and pancreatic tumors. Two main procedures include Endoscopic Retrograde Cholangiopancreatography (ERCP) and endoscopic ultrasonography (EUS):
Endoscopic Retrograde Cholangiopancreatography (ERCP)
ERCP is a specialized technique used to study the drainage ducts of the gallbladder, pancreas and liver. The procedure is used primarily to diagnose and treat conditions of the bile ducts, including gallstones, inflammatory blockages from scarring, leaks (from trauma and surgery) and cancer.
Endoscopic Ultrasonography (EUS)
EUS allows the doctor to examine the stomach lining, and the walls of the upper and lower gastrointestinal tract, as well as study internal organs that are close to the GI tract, like the gall bladder and pancreas. EUS can be used to diagnose the cause of conditions such as abdominal pain or abnormal weight loss. It can also be used to evaluate an abnormality, such as a lump, or diseases of the pancreas, bile duct or gallbladder. For patients with cancer, it can help accurately assess the cancer’s depth and whether it has spread to adjacent lymph nodes. In some cases, it can be used to obtain biopsy samples.
