Sphincter of Oddi dysfunction (SOD) is a syndrome caused by either dyskinesia or stenosis of the sphincter of Oddi. It has been categorized into biliary and pancreatic SOD based on clinical features and laboratory findings. We present a case of a 51-year-old female (post-cholecystectomy) who presented with intermittent chronic right upper quadrant pain. Laboratory investigations showed persistently elevated liver function tests and a dilated common bile duct without the presence of any stones. Endoscopic retrograde cholangiopancreatography with manometry showed an elevated sphincter of Oddi pressure, thus confirming the diagnosis of SOD. She underwent endoscopic sphincterotomy and papillotomy with normalization of liver function tests and resolution of her chronic symptoms.
