Sphincter of Oddi dysfunction (SOD) is one of the causes of post‐cholecystectomy syndrome and biliary pain and is a challenge from both the diagnostic and therapeutic points of view. Sphincter of Oddi dysfunction is typically diagnosed months to years after cholecystectomy. Continued biliary type pain after cholecystectomy may occur in as many as 10–20% of patients. Ten percent or more of these patients may eventually be shown to have SOD. The syndrome is often associated with a variety of other gastrointestinal disorders thought to be caused by dysmotility. According to the Milwaukee classification, patients with biliary pain can be divided into three types. Type I patients show all the objective signs suggestive of a disturbed bile outflow (i.e. elevated liver function tests, dilated common bile duct and delayed contrast drainage during endoscopic retrograde cholangiopancreatography). Type II patients have biliary type pain along with one or two of the criteria from type I. Type III patients have biliary pain only, with no other abnormalities. The present paper will focus primarily on SOD syn‐drome, papillary stenosis and the diagnostic and therapeutic approaches, in particular endoscopic sphincterotomy.
