The sphincter of Oddi is the smooth muscle connection between the bile duct and the duodenum. Pharmacological doses of gastrointestinal hormones also affect the sphincter; CCK octapeptide, glucagon and secretin are able to decrease sphincter of Oddi baseline pressure, and CCK octapeptide abolishes sphincter motility.

Regarding this, what drugs relax the sphincter of Oddi?

Sphincter of Oddi manometry is usually performed at the time of ERCP. All drugs which relax (anticholinergics, nitrates, calcium channel blockers, and glucagon) or stimulate (narcotics or cholinergic agents) the sphincter should be avoided for at least 8-12 hours prior to manometry and during the manometric session.

Subsequently, question is, how do you stop sphincter of Oddi spasm? Medication. Nitrates and calcium channel blockers have been used to help relieve symptoms. These medications can sometimes stop the spasms associated with sphincter of Oddi dysfunction and should be offered first in type III SOD patients before suggesting invasive therapies.

Subsequently, one may also ask, what causes the sphincter of Oddi to relax?

This muscle relaxes during a meal to allow bile and pancreatic juice to flow into the intestine. The pain may be aggravated by meals, particularly fatty foods. Opiates may also worsen symptoms.

Where is your sphincter of Oddi located?

This causes severe stabbing pain like a knife sticking into the rectum.

What controls the sphincter of Oddi?

The sphincter of Oddi is a small sphincter which is strategically placed at the junction of the bile duct and pancreatic duct with the duodenum. It regulates the flow of bile and pancreatic juice into the duodenum and prevents reflux of duodenal contents into the ducts.
