Sphincter of Oddi dysfunction in children.

Sphincter of Oddi dysfunction (SOD) is a clinical entity caused by a primary motility alteration of either the biliary or the pancreatic sphincter. SOD is a rare condition that has been scarcely reported in children. Most of the reported literature has been in children with idiopathic recurrent pancreatitis. These children are treated endoscopically by dual sphincterotomy of the pancreatic and common duct sphincters. However, the safety and efficacy of sphincter of Oddi manometry and sphincterotomy in the pediatric population await further study.
