Acute Pancreatitis in Dogs
Information In-Depth on Pancreatitis in Dogs
Other medical problems can lead to symptoms similar to those encountered in acute pancreatitis. It is important to exclude these conditions before establishing a definitive diagnosis.
Acute pyelonephritis is an infection of the kidneys
Biliary tract obstruction caused by cancer or gall bladder stones (rare). Also, severe pancreatitis can cause compression of the bile duct and clinical symptoms of biliary obstruction (icterus or jaundice – a term that refers to yellow color of the mucous membranes such as the sclera of the eye and the gums).
Intestinal perforation by a foreign body or tumor
Diabetes mellitus with ketoacidosis (accumulation of acid ketone by-products in the blood resulting in metabolic acidosis) can cause symptoms similar to those observed in dogs with pancreatitis. Also, some dogs with diabetes mellitus may have complicating pancreatitis.
Intestinal foreign body
Hemorrhagic gastroenteritis is an inflammatory condition of the gastrointestinal tract that causes clinical symptoms similar to those observed in pets with pancreatitis.
Some inflammatory liver diseases can cause abdominal pain, vomiting and lethargy and thus be confused with pancreatitis.
Intestinal obstruction caused by a tumor or foreign body.
Parvovirus gastroenteritis is an infectious disease caused by a virus that usually affects young unvaccinated dogs.
Peritonitis is an inflammation of the lining of the abdominal cavity, and can be caused by several mechanisms including intestinal perforation. Peritonitis can also occur as a complication of pancreatitis.
Acute prostatitis is an inflammatory condition of the prostate gland usually caused by bacterial infection that can cause severe abdominal pain, fever and lethargy.
Pyometra is an bacterial infection of the uterus in intact female dogs.
Pancreatic abscess can complicate pancreatitis and usually requires surgical treatment.
Kidney failure can produce clinical symptoms (loss of appetite, vomiting, lethargy) similar to those observed in dogs with pancreatitis.
Body-wide bacterial infections (sepsis) can also cause clinical symptoms (loss of appetite, vomiting, lethargy) similar to those observed in dogs with pancreatitis.
Intestinal volvulus is an abnormal twisting of the intestine that can cause clinical symptoms similar to those observed in pancreatitis.
Intestinal intussusception is a telescoping of the intestine onto itself that can cause clinical symptoms similar to those observed in pancreatitis.
Diagnosis In-depth of Pancreatitis in Dogs
Diagnostic tests are needed to recognize acute pancreatitis and exclude other diseases. Tests may include:
Your veterinarian will take a complete medical history and perform a thorough physical examination. The abdominal will be carefully examined by palpation to test for abdominal pain and abdominal masses.
A complete blood count (CBC or hemogram) to evaluate for infection or inflammation, anemia, and low platelet count.
A serum biochemical profile to evaluate the general health of your dog and the possible effects of pancreatitis on other body systems.
Urinalysis may be recommended to evaluate your dog’s kidney function and check for urinary tract infection.
Serum enzyme activities including amylase, lipase and trypsin-like immunoreactivity may be recommended to evaluate for pancreatitis. Some of these enzyme activities (amylase, lipase) are readily available but may be of limited value in the diagnosis of pancreatitis. Trypsin-like immunoreactivity is a test that likely will require shipping of a serum sample to a specialty laboratory.
Abdominal X-rays may be recommended to evaluate the region of the abdomen in which the pancreas is located (“right cranial quadrant”) and to help eliminate other potential causes of your dog’s symptoms.
X-rays taken after administration of a radiographic contrast agent (“GI series” or “barium series”) may be recommended if intestinal obstruction is suspected.
Abdominal ultrasound examination may be recommended. This test may help identify abnormalities within the pancreas and other abdominal organs. Ultrasound examination may identify masses, cysts, or abscesses within the pancreas, and also can identify biliary obstruction caused by pancreatic swelling. This examination may require referral to a veterinary specialist.
Serum canine Pancreatic Lipase Immunoreactivity (PLI or cPLI) concentration is the most reliable test for diagnosis of pancreatitis. This blood test is sent to an outside laboratory. A “SNAP” test that can be done at the clinic but is less reliable. A negative SNAP test result generally eliminates that diagnosis of pancreatitis in dogs but a positive test does not confirm the diagnosis. The Serum PLI being sent to an outside lab is considered the test of choice to diagnosis pancreatitis in dogs.
Treatment In-depth of Pancreatitis in Dogs
Treatment of acute pancreatitis must be individualized and based on the severity of your dog’s condition and other factors that must be analyzed by your veterinarian. Treatments may include:
If your dog has mild acute pancreatitis, outpatient treatment including withholding of food and water for a short time to rest the pancreas, may be recommended. Your veterinarian may also recommend subcutaneous administration of fluids, drugs to control vomiting, and, in some cases, antibiotics to prevent or control bacterial infection. In this situation, regular follow-up visits to your veterinarian are important to insure that the condition does not progress and that your dog does not become dehydrated.
If pancreatitis is moderate or severe, hospitalization likely will be recommended and additional tests and treatments will be performed. Treatment consists primarily of intravenous fluid therapy, withholding of food and water to rest the pancreas, drugs to control vomiting and, in some cases, antibiotics to prevent or control infection. As the animal responds to treatment, water and a bland diet are gradually re-introduced.
Abdominal pain may be treated with cage confinement and analgesic medications such as meperidine or butorphanol.
Antibiotics may be used to control or prevent bacterial infection.
Surgery may be necessary for complications of pancreatitis such as pancreatic abscess, infected pancreatic cyst, peritonitis or biliary obstruction.
Abdominal lavage (flushing of the abdomen with sterile fluids) may be used to promote the removal of activated enzymes from the peritoneal space.
A body-wide clotting disorder (“disseminated intravascular coagulation”) occasionally may complicate pancreatitis and require additional treatment including heparin administration.
