Is there any new research on sphincter of odi disfunction and pain management?

Sphincter of oddi: There a couple of options for pain management and to prevent recurrent pancreatitis including: calcium channel blockers, nitrates, ursodeoxycholic acid, endoscopic or surgical sphincterotomy, and even botulism or electroacupuncture (but these aren't standard treatments, and still needs more data).

SOD : This question is best addressed by a GI (motility) or hepatobilliary specialist in conjuction with a pain management physician. Biliary sphincterotomy or a combination of biliary and pancreatic sphincterotomy may be effective in certain patient depending on the type of sod. Botox injection have been tried with varying success. University setting is usually best place to get treated for sod.
