Chronic pancreatitis in dogs: prognosis and follow-up
9-year-old English Cocker Spaniel with mild, recurrent episodes of vomiting, inappetence and abdominal discomfort over the past 2 years. Ultrasound shows a heterogeneous, irregular pancreas, consistent with chronic pancreatitis.
Which statement about the course of the disease is correct?
chevron_right Show answer and explanation
A. It usually progresses to pancreatic carcinoma, so ultrasound should be repeated every 3 months
Canine chronic pancreatitis has not been shown to progress frequently to carcinoma. Follow-up is based on clinical signs, not serial ultrasound.
B. It is reversible: after each episode the pancreas regains its normal structure
Chronic pancreatitis is defined by irreversible changes (fibrosis and atrophy). It is acute pancreatitis that can resolve without sequelae.
C. Dietary fat has no influence, so he can stay on his usual food
Although evidence is limited, a low-fat diet is recommended, especially if episodes coincide with fatty meals or there is hypertriglyceridaemia.
D. Progressive loss of pancreatic tissue can lead to exocrine pancreatic insufficiency and diabetes mellitus
Correct. Fibrosis destroys both acinar tissue and islets. At check-ups, therefore, monitor body weight, faeces (steatorrhoea, polyphagia) and the onset of polyuria/polydipsia.
lightbulb Key takeaway
Chronic pancreatitis is common, often subclinical and with mild flare-ups. Treat each flare-up as acute pancreatitis, keep the dog on a low-fat diet and watch for EPI and diabetes in the long term: in a diabetic dog, think about the pancreas.
