Pancreatic abscess

Definition

A pancreatic abscess is an area filled with pus within the pancreas.

Causes

Pancreatic abscesses develop in people who have:

Pancreatic pseudocysts
Severe pancreatitis that becomes infected

Symptoms

Symptoms include:

Exams and Tests

Most people with pancreatic abscesses have had pancreatitis. However, the complication often takes 7 or more days to develop.

Signs of an abscess can be seen on:

CT scan of the abdomen
MRI of the abdomen
Ultrasound of the abdomen

Blood culture will show high white blood cell count.

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

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

Prevention

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