The Effects of Morphine–Neostigmine and Secretin Provocation on Pancreaticobiliary Morphology in Healthy Subjects: A Randomized, Double-blind Crossover Study Using Serial MRCP

Secretin-stimulated magnetic resonance cholangiopancreatography (MRCP) is used for the diagnosis of sphincter of Oddi dysfunction (SOD), but it does not correlate well with sphincter of Oddi manometry. Serial MRCP following morphine–neostigmine provocation may be of value in the assessment of SOD, but the effects of these pharmacological agents on pancreaticobiliary morphology in healthy subjects have not been studied. The aim of the present...
