Triaditis refers to an inflammatory process that involves the;
Triaditis is a syndrome unique to cats, and does not appear to occur in dogs and other species.
Unlike the dog, the pancreatic duct in cats enters the common bile duct before it opens into the duodenum. When there is disease (e.g., inflammation, infection, neoplasia, stasis) in the small bowel, it may ascend into the common bile duct and, from there, affect the pancreas, resulting in pancreatitis. The rest of the biliary tree may also be affected.
There appears to be no breed, age or sex predilection for this disease, however pancreatitis and IBD are common in middle-aged to older cats.
Clinical signs are generally vague and non-specific, including anorexia, vomiting, diarrhoea, lethargy and dehydration.
Diagnosis is based on ultrasonographic findings of pancreatitis, cholangiohepatitis and inflammation of duodenum. Blood tests may reveal neutrophilia or chronic non-regenerative anaemia.
Treatment is usually supportive, including fluid therapy, H2 blockers (e.g. famotidine 5 mg orally) to control vomiting, cisapride (5 mg orally every 8 hours) as a promotility drug. Antimicrobial therapy (usually based on culture and sensitivity) should continue for 6 - 8 weeks, or longer.
S-adenosyl-L-methionine (90 mg orally every 12 hours) may be beneficial as a glutathione donor that enhances cellular metabolism.
