The concept that sphincter of Oddi dysfunction (SOD) can cause attacks of biliary-type pain in postcholecystectomy patients and those with unexplained recurrent acute pancreatitis, and that endoscopic sphincterotomy can ameliorate symptoms, remains unproven. The Evaluating Predictors and Interventions in Sphincter of Oddi Dysfunction (EPISOD) study of patients without objective evidence for biliary obstruction showed no difference in outcomes between those who underwent sphincterotomy or sham treatment. 1 To date, there have been no studies examining the characteristics of patients who still are being offered endoscopic retrograde cholangiopancreatography (ERCP) for SOD since the EPISOD publication, although the absolute number appears to have declined. 2.
