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. ==References== {{reflist}} ==External links== * [http://abdellab.sunderland.ac.uk/lectures/Parmacology/Pics/anatomy/BileAnat.jpg Diagram at sunderland.ac.uk] {{Digestive glands}} [[Category:Digestive system]] [[Category:Gastroenterology]] [[fr:Sphincter d'Oddi]] [[it:Sfintere di Oddi]] [[nl:Sfincter van Oddi]] [[pl:Zwieracz Oddiego]] [[ru:Сфинктер Одди]] [[fi:Oddin sulkijalihas]]
