  Therapeutic Endoscopy (ERCP) enables the physician at Gastroenterology Associates to diagnose problems in the liver, gallbladder, bile ducts, and pancreas. It is used primarily to diagnose and treat conditions of the bile ducts, including gallstones, inflammatory strictures (scars), leaks and cancer.
ERCP combines the use of x-rays and an endoscope, which is a long, flexible, lighted tube. Through the endoscope, the physician can see the inside of the stomach and duodenum, and inject dyes into the ducts in the biliary tree and pancreas so they can be seen on x-rays.
If the exam shows a gallstone or narrowing of the ducts, the physician can insert instruments into the scope to remove or relieve the obstruction. Also, tissue samples (biopsy) can be taken for further testing.
ERCP takes 30 minutes to 2 hours. After the procedure, you will need to stay at the hospital for 1 to 2 hours until the sedative wears off. The physician will make sure you do not have signs of complications before you leave. If any kind of treatment is done during ERCP, such as removing a gallstone, you may need to stay in the hospital overnight.
