The purpose of this research study is to see if there is a significant difference in improvement of symptoms and quality of life of those undergoing endoscopic therapy versus those wanting to control their symptoms with medicines or those who just want to wait and watch.

sphincter of oddi dysfunction
endoscopic therapy vs conservative care

Detailed Description:
Sphincter of Oddi is a complex muscular structure which regulates the biliary and pancreatic outflow into the duodenum. Resting pressures >40mm of Hg are considered abnormal. Individuals with elevated resting/basal biliary or pancreatic sphincter pressures are thought to have sphincter of oddi dysfunction. Sphincter dysfunction often manifests as pain and the nature of the pain is dependent on the involvement of either the biliary or the pancreatic sphincter. In most instances the pain is debilitating and could impair the quality of life. Endoscopic therapy- either biliary or pancreatic sphincterotomy, is often performed for relief of symptoms. Data regarding the efficacy of such an approach are limited. A recent systematic review by the Cochrane reviewers has found only two randomized controlled trials evaluating the efficacy of sphincterotomy for relief of symptoms in those with sphincter of Oddi dysfunction and there were no data evaluating the quality of life or the health economics of such an approach.
