Tomorrow is Thanksgiving, and for many families this means the tradition of spending the day preparing and enjoying a delicious turkey dinner with all of the trimmings. Us humans are not the only ones who look forward to this meal, and I see many dogs in the ER after they have decided to help themselves to a serving or two. While our pets may find this to be an initially satisfying (albeit naughty) indulgence, it can set them up for the development of pancreatitis, a potentially life-threatening disease.
What is the job of the pancreas?
The pancreas is an organ that sits cozily just under the stomach and along the first part of the small intestine. The pancreas is all about secretion and it has two main jobs. The first is the secretion of digestive enzymes to help break down food, and the second is the secretion of insulin and glucagon (to regulate sugar metabolism). The digestive enzymes are the part of the story that concerns us in pancreatitis.
Just what is pancreatitis?
Put simply, pancreatitis is inflammation of the pancreas that disrupts its normal integrity. Digestive enzymes that are normally safely stored are released prematurely, beginning to digest the body itself, and the result can be a metabolic catastrophe. As the tissue becomes further inflamed, the damage begins to involve its next-door neighbor, the liver. Toxins released from this progressive party of tissue destruction can circulate more broadly, causing a body-wide inflammatory response. If the pancreas is severely affected, its ability to produce insulin can be affected and diabetes can result.
The good news is that most commonly the inflammation is confined to the area of the liver and pancreas, and most pets make a full recovery with support.
What causes pancreatitis?
In most cases, we never find out what causes it but we do know some events that trigger it. These can include:
Miniature Schnauzers are predisposed to pancreatitis as they commonly have altered fat metabolisms.
Signs of Pancreatitis
The classical signs are appetite loss, vomiting, diarrhea, painful belly, depressed attitude and fever.
Making the Diagnosis
Until recently, a reliable blood test has been lacking. A new newer generation option called the SPEC cPL (specific canine pancreatic lipase) test has come to be the lab test of choice. For dogs only, the SPEC cPL can be run overnight by a reference lab and is able to detect 83 percent of pancreatitis cases and exclude other possible diseases in 98 percent of cases.
This test should not be confused with the “in-hospital” pancreatic test, which resembles a “pregnancy test” and gives you an answer of “abnormal” or “normal.” I am personally not a huge fan of this test because other disease processes (such as liver or gastrointestinal disease) can cause an “abnormal” result.
Ultrasound detects 68 percent of cases and provides the opportunity to look at other organs. Since pancreatitis can be accompanied by a tumor near the pancreas, ultrasound is an important tool for catching such complicating factors. I discuss and recommend this diagnostic for all patients I suspect have pancreatitis.
The passage of food through the intestine is a strong stimulus to the pancreas, which is what we want to avoid. Essentially, we want the pancreas to “rest.” This generally means no food or water for 2 to 3 days (in our very ill patients) using IV fluid support to prevent dehydration. Fluid support generally requires electrolyte supplementation and a critical patient will need 24-hour care with blood-test monitoring several times a day. A plasma transfusion represents a specific type of fluid therapy and may be of great help in severe cases.
Pancreatitis can be a very painful condition and pain management is of utmost importance in recovery and is a cornerstone of treatment. Untreated pain affects the immune system and has been shown to increase death rate. Medications to control nausea are also used. Antibiotics are used because even though pancreatitis is not a bacterial disease, bacterial invasion from the diseased intestine is a common occurrence.
Once the patient has started to eat again, a low-fat diet is important to minimize pancreatic stimulation. Since there is potential for the pancreas to always have a smoldering bit of inflammation, long-term use of a low-fat diet is likely to be recommended.
Pancreatitis can be a very severe disease to experience and treat and I hope this helps raise awareness of a potential source of calamity. Please remember to keep your countertops pet-safe: Take all garbage outside promptly and be extra vigilant of the fact that even the most well behaved pets can be tempted with all of the food festivities.
Here’s to a SAFE, happy and wonderful Thanksgiving!
