Sphincter of Oddi dysfunction refers to two motility conditions affecting the Sphincter of Oddi; papillary stenosis and sphincter of Oddi dyskinesia (also known as biliary dyskinesia). The sphincter of Oddi is a sphincter muscle, a circular band of muscle at the bottom of the biliary tree which controls the flow of pancreatic juices and bile into the second part of the duodenum. Both types of dysfunction can obstruct to flow through the sphincter of Oddi and can therefore cause retention of bile in the biliary tree and pancreatic juice in the pancreatic duct.

Sphincter of Oddi dysfunction is a rare condition. However, as with most conditions, certain factors make it more likely, such as patients with biliary-pancreatic disease[1].

Contents

Presentation

Sphincter of Oddi dysfunction may be suggested by pain which seems to come from a biliary origin, which may or may not be associated with transient increases of liver or pancreatic enzymes. Common bile duct dilation and episodes of pancreatitis are also signs.[2]

Diagnosis

For diagnosis, measures of live biochemistry and pancreatic enzymes are performed. Along with ruling out structural abnormalities, normally by performing an abdominal ultrasound and endoscopic retrograde cholangiopancreatography (ERCP). Measurements of bile transit when performing ERCP are taken to help evaluate different treatment options.[3]

Treatment

Sphincter of Oddi manometry or Sphincterotomy are the standard treatments for sphincter of Oddi dysfunction. One or the other may be better based on the classification of the condition.[4]
