Go to UCLA "...There are two main types of sphincter of Oddi dysfunction. A clinical syndrome with predominance of biliary-type pain, abnormalities of liver enzymes, and dilation of the bile duct will be referred to as biliary-type sphincter of Oddi dysfunction. Another variant with predominance of pancreatic problems, mainly recurrent episodes of acute pancreatitis is known as pancreatic-type sphincter of Oddi dysfunction.

Biliary-type pain is typically located in the right upper quadrant area of the abdomen, the area in the upper abdomen below the right side of the rib cage. It can sometimes radiate to the shoulder blade or to the mid-back. It commonly occurs after the ingestion of meals, in particular after nutrients with a high fat content. The pain is constant and typically persists for 45 minutes up to several hours. Most patients who present with these symptoms are initially thought to have gallbladder problems, and frequently undergo cholecystectomy. However, their symptoms persist following cholecystectomy. This is the reason why biliary-type sphincter of Oddi dysfunction is sometimes also referred to as post-cholecystectomy syndrome. Strictly speaking, however, post-cholecystectomy syndrome is a rather broad term used to describe abdominal pain symptoms of varying etiologies that can persist or occur after a cholecystectomy. The causes of post-cholecystectomy syndrome may include conditions such as sphincter of Oddi dysfunction or even irritable bowel syndrome (IBS)..."
