The value of ERCP, SOM and sphincter ablation therapy was studied in 51 patients with idiopathic pancreatitis [39].
The therapeutic approach in patients with SOD is aimed at reducing the resistance caused by the sphincter of Oddi to the flow of bile and/or pancreatic juice [7].
In contrast, only 30-40% of patients with an elevated sphincter pressure treated by sham sphincterotomy or with a normal sphincter pressure treated by endoscopic sphincterotomy or sham sphincterotomy benefited from this therapy.

 What is sphincter of oddi dysfunction and the symptoms?
Sphincter of Oddi dysfunction is a condition in which the sphincter (located at the jumction of bile duct and duodenum) fails to relax appropriately.
Because Sphincter of Oddi dysfunction is a condition in which the sphincter fails to relax appropriately I was wondering because I have fibromyalgia which deals with muscles throughout the body that there could be some correlation between the two.

 Sphincter
The sphincter is a circular muscle that constricts a passage or closes a natural orifice.
That causes the detrusor muscle to contract and the sphincter mechanism to relax.
During urination, the detrusor contracts and the sphincter mechanism relaxes, allowing smooth outflow of urine.

 UpToDate Clinical manifestations and diagnosis of sphincter of Oddi dysfunction
The muscle fibers of the sphincter pancreaticus are interlocked with those of the sphincter choledochus in a figure eight pattern.
Although the pancreatic and biliary sphincter portions of the SO can be distinguished anatomically, their manometric features are similar and a direct anatomic and manometric correlation has not been established.
A circular aggregate of muscle fibers known as the sphincter choledochus (or sphincter of Boyden) maintains resistance to bile flow, and thereby permits filling of the gallbladder during fasting and prevents retrograde reflux of duodenal contents into the biliary tree.

The normal gallbladder contracts through muscular activity in response to food, forcing bile through its exit channel (the cystic duct) and into the bile duct for passage into the intestine (through the sphincter of Oddi or the papilla of Vater).
Dysfunction can be recognized by a special technique during ERCP, called sphincter of Oddi manometry (SOM).
Thus, this condition should be approached and managed with considerable care.

 Treating the Anal Sphincter
There is evidence that hemorrhoid sufferers have increased tightness of the anal sphincter, and some studies are showing that a variety of anal sphincter-relaxing remedies may promote improvement in prolapsed internal hemorrhoids and thrombosed external hemorrhoids, possibly avoiding surgery, or make it possible to to use techniques short of scalpel hemorrhoidectomy.
ANAL FISSURES have been found to be associated with increased anal sphincter muscle tone, and the research demonstrating fissure healing with calcium channel blockers and other agents may be applicable to external hemorrhoids......
The most interesting development in medicinal treatment of hemorrhoids has to do with the use of agents that relax the anal sphincter.
