  • Trauma
  • Tumors
  • Pseudocysts—build up of fluids and debris
Chronic pancreatitis is a risk factor for developing pancreatic cancer .

Symptoms

Symptoms may be mild, but progressive. Chronic pancreatitis may cause:
  • Abdominal pain that may get worse when eating or drinking, spreads to the back, or becomes constant and disabling
  • Nausea and vomiting
  • Weight loss
  • Diarrhea

Diagnosis

You will be asked about your symptoms and medical history. A physical exam will be done. The diagnosis of chronic pancreatitis is difficult. Symptoms are not specific early on in the course of the disease.Your bodily fluids and waste products may be tested. This can be done with:
  • Blood tests
  • Stool tests
Images may be taken of your bodily structures. This can be done with:

Treatment

The goals of treatment for chronic pancreatitis are to relieve pain and manage nutritional and metabolic problems.Treatment may be started in a hospital until you are stabilized. Stabilization can be done with:
  • IV fluids
  • Nasogastric tube—A long, thin tube is threaded through your nose and into your stomach for feeding

Medications

Your doctor may recommend:
  • Prescription pain relievers
  • Pancreatic enzymes
  • Vitamin supplements
  • Medications to control diabetes if it develops

Lifestyle Changes

You will be advised to stop drinking alcohol. This may require counseling or a rehabilitation program. Stopping your alcohol intake is the most important intervention in your treatment. If you smoke, talk to your doctor about how you can successfully quit . You may be advised to restrict the amount of fat in your diet. Pancreatic damage interferes with the body's ability to process fats. A registered dietitian can work with you and create a healthy meal plan.

Surgery

Surgery may be needed in severe cases:
  • Necrosectomy—Removal of dying or dead (necrotic) pancreatic tissue. Pancreatic necrosis is more serious if an infection is present. This procedure can also be done with endoscopy.
  • ECRP—To open any collapsed ducts or drain cysts.
  • Cholecystectomy —To remove the gallbladder.
