underwent ERCP with sphincterotomy and 9/13 were treated conservatively. In patients undergoing sphincterotomy, there were no procedural complications and all had relief of pain (two patients later solicited further ERCP and sphincterotomy). Conclusion In this series, secretin-MRCP was valuable in a group of patients with suspected SOD. Most scan findings for this indication are normal, but in some patients an abnormal scan is valuable in giving a positive diagnosis. A subgroup of these may benefit from ERCP with sphincterotomy, while others respond adequately to conservative therapy. Competing interests None declared.
