Treatment
It may be possible to drain the abscess through the skin (percutaneous). Abscess drainage can be done through an endoscope using endoscopic ultrasound (EUS) in some cases. Surgery to drain the abscess and remove dead tissue is often needed.
Outlook (Prognosis)
How well a person does depends on how severe the infection is. The death rate from undrained pancreatic abscesses is very high.
Possible Complications
Complications may include:
- Multiple abscesses
-
Sepsis
Sepsis
Sepsis is an illness in which the body has a severe, inflammatory response to bacteria or other germs.
When to Contact a Medical Professional
Contact your health care provider if you have:
- Abdominal pain with fever
- Other signs of a pancreatic abscess, especially if you have recently had a pancreatic pseudocyst or pancreatitis

Draining a pancreatic pseudocyst may help prevent some cases of pancreatic abscess. However, in many cases, the disorder is not preventable.

The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

Endocrine glands - illustration
Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the rate of metabolism in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).

The pancreas is an elongated, tapered gland that is located behind the stomach and secretes digestive enzymes and the hormones insulin and glucagon.
