Where is duodenum found

Duodenitis is an inflammation of the lining of the duodenum. Common conditions of the duodenum, such as duodenitis, may be acute short term and severe or chronic long term. The condition may not result in any symptoms at all; it may be diagnosed when a person is being examined for another type of digestive disorder. In other instances, symptoms such as discomfort or a burning sensation in the abdominal region may be present.

Other symptoms may include:. Several tests are commonly used to diagnose conditions of the duodenum, including duodenitis.

Acute pancreatitis is commonly caused by gallstones that have travelled along the common bile duct and have become trapped in a position where they obstruct the pancreatic duct. Pancreatic juice becomes trapped in the pancreas and pancreatic enzymes may start to digest the internal pancreatic tissue, triggering severe inflammation and pain.

Acute pancreatitis may also be caused by excessive consumption of alcohol and is particularly associated with binge drinking. The exact mechanism is unclear, but it is thought that alcohol may activate pancreatic enzymes while they are still in the pancreas, leading to autodigestion and inflammation. Pancreatitis is also often seen in patients with cystic fibrosis and can be triggered by certain drugs, such as the antibiotic tetracycline.

The symptoms of pancreatitis are similar to those of gallstones, with upper abdominal pain radiating into the back. The pain often becomes worse after eating and may be associated with a fever. Some patients experience relief when they lean forward. Most cases of mild pancreatitis will resolve and symptoms gradually disappear after about a week.

However, severe cases often require hospital admission, possibly in a high-dependency unit, and opioids for pain relief. Unresolved acute pancreatitis can turn into chronic pancreatitis, most often seen in patients with alcohol dependency. This is characterised not only by chronic pain, but also by long-term inflammation of the pancreas that can lead to progressive tissue fibrosis as a result of the deposition of collagenous scar tissue.

PEI most frequently manifests as poor digestion of fats leading to steatorrhoea. Poor digestion of fats — whether resulting from PEI, gall bladder disease or cholecystectomy — may impair the absorption of key fat-soluble vitamins, so patients may need to take supplements to avoid deficiencies.

Each year, around 8, people are diagnosed with pancreatic cancer, which causes around 5. Pancreatic cancer is predicted to overtake breast cancer as the fourth most common cause of cancer death by Pancreatic Cancer UK, Age is the main risk factor and most cases are diagnosed after the age of Modifiable risk factors include smoking, obesity and inactivity. Pancreatic cancer is usually treated with surgery, which may be curative if the tumour is discovered early or palliative.

Many patients may also undergo chemotherapy or radiotherapy with the aim of reducing the size of the tumour Kleeff et al, Treatments specifically targeting pancreatic tumour cells have been recently developed but are not yet widely available Amanam and Chung, Tagged with: Newly qualified nurses: systems of life.

Gastrointestinal tract 3: the duodenum, liver and pancreas. Abstract After its passage through the stomach, ingested food turned into acidic chyme arrives in the first segment of the small intestine, a U-shaped tube called the duodenum.

Key points The duodenum is the first segment of the small intestine; the liver and pancreas are the two major accessory organs of the gut The major role of the duodenum is as a vessel for chemical digestion and, to a lesser extent, the absorption of minerals Chemical digestion in the duodenum relies on bile secreted by the liver and pancreatic juice secreted by the pancreas To prevent autodigestion and corrosion, gastric acidity is neutralised in the duodenum by pancreatic juice Patients with impaired digestion of fats may lack vitamins A, D, E and K.

It takes many peristaltic contractions over the course of an hour for chyme to travel through the entire length of the duodenum. Small regional contractions of the intestinal wall, known as segmentations, help to mix chyme with the digestive secretions in the duodenum and increase the rate of digestion. Segmentations also increase the contact of chyme with the mucosal cells to increase the absorption of nutrients through the intestinal wall.
