Abstract
Sphincter of Oddi dyskinesia (SOD) is among the less frequent causes of acute recurrent
pancreatitis. We report on a patient with frequent pain attacks accompanied by pancreatic
enzyme elevation, in whom a transitory decrease of the SO pressure following endoscopic
botulinus toxin injection was a diagnostic clue for SOD.
The patient's symptoms resolved for 4 months, after which time recurrent symptoms
paralleled the reoccurrence of the elevated SO pressure. Endoscopic sphincterotomy
of the biliary sphincter relieved her symptoms for the subsequent follow-up period
which is now 10 months.
