Opiates have long been implicated in causing common bile duct (CBD) dilation but few studies have been done to look at the association between synthetic opiates – methadone – and asymptomatic CBD dilation. The mechanism by which methadone could cause CBD dilation is poorly understood, but it has been postulated that increase in biliary pressures from contraction of the sphincter of Oddi is likely. In the below article, we review all the evidence pertaining towards
methadone causing common bile duct dilation.
