Dr. Kamran Ayub performs area’s first specialized Sphincter of Oddi Manometry procedure

Joliet, IL (February 9, 2012)— The Sphincter of Oddi is a muscle valve that controls the flow of digestive juices (which includes bile and pancreatic juice) through ducts from the liver and pancreas into the small intestine. When it’s working properly, the Sphincter of Oddi opens to allow bile and pancreatic juice to flow through and then closes again. However, in a condition called Sphincter of Oddi dysfunction, the sphincter muscle does not open when it should and goes into spasm. This prevents the bile and pancreatic juice from flowing through and causes a backup of digestive juices which can cause bouts of severe pain in the abdomen.

"The body’s digestion system is very complex, it takes many functions to process the food we eat into the energy we need. The Sphincter of Oddi muscle controls vital digestive enzymes and fluids needed from the liver and pancreas into the small intestine,” shares Dr. Kamran Ayub, Gastroenterologist on staff at Silver Cross Hospital.

There are two basic types of Sphincter of Oddi dysfunction. The first is when the digestive juices are backing up in the bile ducts and the liver; this is called the biliary type dysfunction. The second type is the backup occurring in the pancreas; it is called pancreatic type dysfunction. “The pain symptoms are very similar to those caused by bile duct or gallbladder stones for the biliary type, and pancreatitis type pain for the pancreatic type,” shares Dr. Ayub. “Abdominal pain is often the most common symptom; however other features include nausea, vomiting, abnormal liver or pancreatic enzymes, fever and weakness. These symptoms can come and go, and can be mild one time and severe the next.”

When symptoms are severe, laboratory and scanning tests are taken. To make a diagnosis it is recommended that patients undergo an endoscopic procedure called Endoscopic Retrograde Cholangio Pancreatography (ERCP) with sphincter of Oddi manometry. This is an endoscopic procedure that uses x-ray pictures of the ducts (drainage routes) of the gallbladder, liver and pancreas and obtains pressure readings of the Sphincter of Oddi muscle. An instrument is passed down through the throat and into the duodenum, where the bile and pancreatic ducts drain fluid. A dye is injected into these ducts and a special catheter is passed into the ducts to measure the pressure of the sphincter. If the pressure is elevated, a small electrical incision is made through the sphincter muscle and this relieves the sphincter pressure and clears any blockage occurring in the Sphincter of Oddi muscle. This procedure is done under sedation, so patients do not feel any pain.

“This allows the physician to remove any blockage or to relieve any scarring or spasm of the sphincter and help patients find relief,” says Dr. Ayub.
