Figure 10. Postcholecystectomy sphincter of Oddi dysfunction (SOD) responding to endoscopic sphincterotomy. This 37 year old woman complained of recurrent right upper quadrant pain one year after cholecystectomy. Ultrasound was normal. 99mTc-IDA imaging shows prolonged retention in the biliary tree and a protracted bile duct curve (a). Symptoms resolved after endoscopic sphincterotomy and bile duct emptying also returned to normal (b).
