If sphincter of Oddi dysfunction is confirmed to be causing a patient’s symptoms, what is the best next step?
The approach to a patient with suspected sphincter of Oddi dysfunction (SOD) depends upon the patient’s clinical presentation as well as the results of laboratory testing and abdominal imaging. In general, only patients fulfilling the Rome III criteria should undergo invasive evaluation for SOD. This decreases the chance of patients being inappropriately subjected to invasive testing for SOD that is associated significant complications (primarily pancreatitis). (See ‘Rome III criteria’ above and ‘Sphincter of Oddi manometry’ below.)
To determine if patients fulfill the Rome III criteria, liver tests (transaminases, alkaline phosphatase, bilirubin) and pancreatic enzymes (amylase, lipase) should be checked, and structural abnormalities need to be excluded. Transabdominal ultrasound is typically the initial imaging study obtained for suspected biliary SOD. It can look for structural abnormalities such as gallstones while also providing an estimate of the common bile duct diameter. However, transabdominal ultrasound may not adequately visualize the pancreas because of overlying bowel gas, so alternate imaging techniques, such as magnetic resonance cholangiopancreatography (MRCP), may be required for evaluation of the pancreatic duct. Additional testing that may help to rule out structural abnormalities includes abdominal computed tomography, endoscopic ultrasound, and endoscopic retrograde cholangiopancreatography (ERCP).
In appropriately selected patients, the diagnosis of SOD is established by sphincter of Oddi manometry (SOM), which is performed during ERCP. Several less invasive methods have also been evaluated for establishing the diagnosis, but none has been shown to approach the diagnostic accuracy of SOM [28,30]. (See ‘Sphincter of Oddi manometry’ below.)
