Help! Any vets out there? Need more info on "Feline Triad Disease"?

My cat was recently diagnosed with "Feline Triad Disease". Guess it's a mild case, but would like to learn more. Not much info on the internet. It's also called trianitis. I just don't want to believe that this eventually becomes chronic. What causes this? The vet still hasn't confirmed the pancreatitis part, just the IBD and liver problems (although they did the exploratory surgery and his pancreas was slightly inflamed). Thanks for your help!
