The '''Sphincter of Oddi''', also called the '''hepatopancreatic sphincter''' or '''Glisson's sphincter''', controls secretions from the [[liver]], [[pancreas]], and [[gallbladder]] into the [[duodenum]] of the [[small intestine]]. It is named after [[Ruggero Oddi]].<ref>{{WhoNamedIt|synd|2709}}</ref>
It is a [[sphincter]] muscle located at the surface of the duodenum. It appears slightly distal to the joining of the [[common bile duct]] and [[pancreatic duct]] as they enter the descending duodenum and forms from the [[ampulla of Vater]]. [[Bile]] and pancreatic secretions enter the digestive system through this point. The opening on the inside of the descending duodenum after the sphincter of Oddi is called the [[major duodenal papilla]] (of Vater).
==Clinical significance==
[[Endoscopic retrograde cholangiopancreatography|Endoscopic retrograde cholangiopancreatogram]]s (ERCPs), which are [[Radiography|radiographic]] examinations of the biliary system, often involve assessment of the bile ducts with a [[esophagogastroduodenoscopy]] via the sphincter of Oddi before the injection of iodinated contrast medium.
