Summary
Pancreatolithiasis, a rare feline condition, can cause pancreatic duct obstruction and is linked to chronic pancreatitis. This case highlights hypercalcemia as a potential clinical sign in cats with this condition.
Area of Science:
- Veterinary Medicine
- Gastroenterology
- Pathology
Background:
- Pancreatolithiasis is uncommon in cats, with poorly understood causes, unlike in humans where it's a sequela to chronic pancreatitis.
- Feline triaditis involves inflammation of the liver, pancreas, and duodenum.
Observation:
- A cat presented with suspected hepatobiliary disease, elevated pancreatic enzymes, and hypoalbuminemia.
- Abdominal ultrasound revealed acute pancreatitis with pancreatic stones (pancreatoliths) in the duct.
- The cat later developed hypercalcemia and obstructive pancreatolithiasis, leading to euthanasia.
Findings:
- Post-mortem examination confirmed severe chronic pancreatitis, cholangiohepatitis, and duodenitis (triaditis).
- Multiple calcium carbonate pancreatoliths caused pancreatic duct obstruction.
- This is the first reported case of hypercalcemia in a cat with obstructive pancreatolithiasis.
Implications:
- This case suggests pancreatolithiasis in cats may share a similar pathogenesis to humans.
- It adds to the evidence that pancreatolithiasis can develop secondary to chronic pancreatitis in felines.
- Hypercalcemia should be considered in cats presenting with obstructive pancreatolithiasis.

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

190
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

01:27Acute Pancreatitis I: Introduction
529
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...
