Pancreatitis - series

Normal anatomy

The pancreas is located in the upper part of the abdomen, behind the stomach. It contains cells that secrete the hormone insulin, and cells that secrete digestive enzymes that aid in the breakdown of food in the gastrointestinal tract. The pancreas secretes these enzymes into the pancreatic duct, which joins the common bile duct from the liver and drains into the small intestine.

Indication

Inflammation of the pancreas, or pancreatitis, is a serious condition that is most commonly caused by either alcohol toxicity or gallstones.

Gallstones can lodge in the common bile duct and block the flow of pancreatic enzymes out of the pancreas into the intestine.

Pancreatitis due to alcohol toxicity is most often seen in chronic alcoholic patients. Most often, pancreatitis goes away with nonsurgical therapy. The patient will not be allowed to eat for three to five days, to prevent secretion of enzymes by the pancreas. He will also receive pain medication to control the pain caused by pancreatic inflammation.

Procedure

If pancreatitis is due to gallstones, most often the responsible gallstone passes into the intestine spontaneously, and the pancreatitis goes away.

Less commonly, a minor surgical procedure is necessary to extract a gallstone that is blocking the pancreatic duct where it drains into the small intestine. An endoscope, with a camera on its end, is passed down the esophagus, through the stomach, and into the small intestine. The entrance of the pancreatic duct into the small intestine can be viewed through the endoscope. A special instrument on the end of the endoscope can then be passed into the pancreatic duct and the gallstone is extracted.

Very rarely pancreatitis is severe enough to require surgery, which is usually performed when the pancreas becomes infected. Dead pancreatic tissue is removed, and the area around the pancreas is washed clean. Patients who require such treatment usually have prolonged hospital stays and are seriously ill.
