n South African Gastroenterology Review - Sphincter of Oddi dysfunction review : review

Abstract

The term sphincter of Oddi dysfunction (SOD) has been used to describe a clinical syndrome of biliary or pancreatic obstruction related to mechanical or functional abnormalities of the sphincter of Oddi.

---

SOD is defined as recurrent, acalculous, upper abdominal pain resulting from static or intermittent biliary obstruction at the level of the sphincter, due to any combination of inflammatory, fixed fibrotic or dynamic motility abnormalities. A review of SOD is important for gastroenterologist to know, as SOD is one of the definite risk factors of post ERCP pancreatitis.
