sphincter of Oddi

This structure was later to be known as the eponymous "sphincter of Oddi".

There, the two ducts are surrounded by the muscular sphincter of Oddi.

The sphincter of Oddi acts as a mechanical barrier.

The effect of somatostatin on the human sphincter of Oddi has not been established.

In a normal healthy individual with a normally functioning sphincter of oddi there should be no air within the biliary tree.

Sphincter of Oddi dysfunction is a rare condition.

The sphincter of Oddi is a muscular valve that controls the opening of the ampulla.

There is a claim that morphine may constrict the sphincter of Oddi, but this is controversial.

It is also used as a preventive for patients with recurring biliary dyskinesia (sphincter of Oddi dysfunction).

In the prairie dog and rabbit, somatostatin has been shown to inhibit sphincter of Oddi motility, but this effect may be species specific.

Opiates can cause spasms of the sphincter of Oddi, leading to increased serum amylase levels.

This raises the question of whether octreotide increases sphincter of Oddi pressure, rendering ductal cannulation more difficult.

The pain associated with post-cholecystectomy syndrome is usually ascribed to either sphincter of Oddi dysfunction or to post-surgical adhesions.

Causes include a biliary-enteric anastomosis, an incompetent sphincter of Oddi and spontaneous biliary-enteric fistula.

Steinberg WM. Sphincter of Oddi dysfunction: a clinical controversy.

When the sphincter of Oddi is closed, newly synthesized bile from the liver is forced into storage in the gall bladder.

Medication (to prevent spasms) or Sphincterotomy (surgical procedure to cut the muscle) are the standard treatments for sphincter of Oddi dysfunction.

Inflammation of the junction of the duodenum and common bile duct at the sphincter of Oddi is referred to as "odditis".

The gastrointestinal hormone cholecystokinine has been shown to have an opposite effect on the human sphincter of Oddi compared with that of the rabbit and prairie dog.

Excitatory effects of somatostatin or octreotide on the sphincter of Oddi may impair biliary and pancreatic duct outflow.

Also it does not cause spasm of the sphincter of Oddi, making it more suitable than morphine for the treatment of biliary or pancreatic pain.

The sphincter of Oddi, or Glisson's sphincter, controlling secretions from the liver, pancreas and gall bladder into the duodenum.

The bile duct is cannulated with the assistance of a guidewire and the sphincter of Oddi that is located at its base is typically cut.

It also affects the esophageal sphincter and the sphincter of Oddi by reducing contraction as well as increasing motility (movement) of the stomach and intestine.
