What is necrotizing pancreatitis?
In this article, we look at the symptoms and causes of necrotizing pancreatitis, as well as how doctors treat it.
Understanding necrotizing pancreatitis
The pancreas produces enzymes used in the digestion of food.
Necrotizing pancreatitis occurs when pancreatic tissue dies due to inflammation. When a person has necrotizing pancreatitis, bacteria may spread into the dead tissue and cause an infection.
The pancreas is an organ behind the stomach that makes enzymes to help digest food. When the pancreas is healthy, these enzymes pass through a duct into the small intestine.
If the pancreas becomes inflamed, these enzymes may leak into the pancreas and damage the tissues. This is called pancreatitis.
If the damage is severe, blood and oxygen may not be able to reach some parts of the pancreas, leading to tissue death.
The primary symptom of necrotizing pancreatitis is abdominal pain. A person may feel abdominal pain in several places, including:
- at the front of the abdomen
- near the stomach
- around to the back
Pain may be severe and can last for several days. Other symptoms that may accompany pain include:
Necrotizing pancreatitis may lead to a bacterial infection and sepsis if left untreated.
Sepsis is a condition where a person's body reacts adversely to bacteria in their bloodstream, possibly causing the body to go into shock.
Shock may be life-threatening, as it reduces the blood flow to major organs. This may damage them temporarily or permanently. Without treatment, a person may die from sepsis.
Necrotizing pancreatitis may also cause a pancreatic abscess.
Gallstones cause the majority of acute pancreatitis cases.
Necrotizing pancreatitis is a complication of acute pancreatitis. It may happen when acute pancreatitis is untreated, or treatment is ineffective.
Pancreatitis is inflammation of the pancreas. The most common causes of pancreatitis are drinking too much alcohol or having gallstones. Gallstones are small stones, often made of cholesterol, that form in the gallbladder.
The two main types of pancreatitis are:
- Acute pancreatitis, which is when symptoms come on suddenly. About 20 percent of people with acute pancreatitis go on to develop complications, including necrotizing pancreatitis.
- Chronic pancreatitis, which is when symptoms are reoccurring. In rare cases, it may cause necrotizing pancreatitis.
Pancreatitis may also be caused by:
- injury to the pancreas
- tumor in the pancreas
- high levels of calcium
- high levels of fats called triglycerides in the blood
- pancreatic damage from medicine
- autoimmune conditions
- hereditary conditions that affect the pancreas, such as cystic fibrosis
When a person has pancreatitis, digestive enzymes leak into the pancreas. This causes tissue damage and prevents blood and oxygen from reaching those tissues. Left untreated, parts of the pancreas may die.
Nearby bacteria may then infect the dead pancreatic tissue. Infection is what causes some of the more severe symptoms of necrotizing pancreatitis.
To diagnosis necrotizing pancreatitis, a doctor may examine a person's abdomen and ask questions about their symptoms. They may also do blood tests to look for:
- pancreatic enzyme levels
- sodium, potassium, or glucose
- triglycerides levels
They may also use the following tests to look at the pancreas:
If these tests show that a part of the pancreas has died, the doctor may take a biopsy to test for infection.
Doctors treat necrotizing pancreatitis in two stages. Firstly, they treat the pancreatitis. Doctors then treat the part of the pancreas that has died separately.
Medication, including pain relievers, may be prescribed to treat pancreatitis.
Treatments for pancreatitis include:
- intravenous (IV) fluids
- pain relieving medication
- medication to prevent nausea and vomiting
- nasogastric feeding
Nasogastric feeding is when a person is fed liquid food through a tube in their nose. Feeding a person in this way gives the pancreas a rest from producing digestive enzymes.
Treating dead or infected pancreatic tissue
The second stage of treatment for necrotizing pancreatitis targets the dead part of the pancreas.
Doctors may need to remove dead tissue. If the tissue has become infected, a doctor will also prescribe antibiotics.
To remove dead pancreatic tissue, a doctor may insert a thin tube called a catheter into a person's abdomen. They will remove the dead tissue through this tube. If this does not work, open surgery may be required.
According to a 2014 study, the best time to perform surgery is 3 or 4 weeks after the onset of the condition. However, if a person is very unwell, surgery to remove the dead or infected tissue may need to happen sooner.
If a person develops sepsis from an infection caused by necrotizing pancreatitis, this may be life-threatening. To treat sepsis, a doctor will give a person:
- IV fluids
- breathing support
Treating the early signs of infection is the best way to prevent sepsis.
It is not always possible to prevent pancreatitis and its complications. However, they are less likely to occur if a person has a healthy pancreas.
The following may help support the health of a person's pancreas:
- not drinking too much alcohol
- maintaining a healthy weight
- avoiding crash diets
- not skipping meals
If a person has any symptoms of pancreatitis, they should speak to their doctor. Early treatment is the best way to reduce the risk of necrotizing pancreatitis or other complications.
It is essential to recognize the symptoms of necrotizing pancreatitis and speak to a doctor immediately. Getting the right diagnosis and treatment is the best way to reduce complications.
Without treatment, necrotizing pancreatitis may lead to an infection or sepsis. This can lead to life-threatening organ damage.
Necrotizing pancreatitis is very treatable. Treatments target the pancreatitis itself and then the dead or infected tissue. With timely, proper treatment, a person who has had necrotizing pancreatitis should make a full recovery.
Making lifestyle changes to improve pancreatic health is the best way to avoid further problems.
