Sphincter of Oddi dysfunction (SOD), an abnormality of sphincter of Oddi contractility, may cause pancreatobiliary-type pain, cholestasis, or recurrent pancreatitis. Sphincter of Oddi manometry (SOM) is considered by most authorities to be the most accurate method to assess for SOD, and is most commonly performed at ERCP. Physicians who perform SOM must have appropriate training, beyond that typically acquired with ERCP exposure during the course of a three-year clinical GI fellowship. This review discusses the technique of SOM, with an emphasis on the technical and cognitive skill sets required.
