Study Overview
Brief Summary
Bile duct cancer and pancreatic cancer are cancers that cannot be surgically removed. As the cancer grows, it blocks the drainage of the bile ducts that carry digestive juices from the gallbladder and pancreas to the small intestine. ERCP (endoscopic retrograde cholangiopancreatography) is often prescribed during which a tube with a tiny camera attached is inserted through the subject's mouth and advanced to a place in the small intestine where the bile duct empties. Through this scope the doctor enlarges the ducts with tiny balloons and places plastic or metal stents (straws) that help keep the bile ducts open so they can drain properly. However, due to the cancer, the stents are blocked eventually.
The purpose of this registry is to record information and evaluate the impact of endoscopic radiofrequency ablation (RFA) probes in improving the management of bile duct cancer or pancreatic cancer by ablating the tissue in the bile duct(s) before the stent(s) are implanted. By using radiofrequency (RF) energy to heat the tissue in the duct(s) prior to stent(s) insertion, the surrounding tissue becomes coagulated and this may delay tumor growth and the time before the stent lumen becomes blocked. Thereby, allowing increased periods between the need for intervention and further stent implantation(s). The registry will evaluate the efficacy and safety of RFA procedures conducted for pancreatico-biliary disorders
