Cholangitis is defined as the inflammation of the bile ducts, while Cholangiohepatitis indicates that the inflammation has extended into the surrounding liver tissue. In the feline patient, this condition is frequently driven by a unique anatomical feature. Unlike other species, the cat's bile duct and pancreatic duct join together into a single common channel before entering the small intestine. This shared opening allows bacteria from the intestines to easily ascend and infect both the liver and the pancreas simultaneously. Consequently, this condition is a primary component of Feline Triaditis, a syndrome involving concurrent inflammation of the liver, pancreas, and intestines (IBD). For the Chronic Kidney Disease (CKD) cat, this is a severe complication as it exacerbates nausea and anorexia (refusal to eat). A hallmark clinical sign is icterus (jaundice), where the ears, gums, or whites of the eyes take on a yellow hue due to the inability to process bilirubin. Diagnosis relies on blood tests revealing elevated liver enzymes (ALT, GGT) and ultrasound imaging. Treatment typically involves antibiotics to clear infection and medications like Ursodiol to improve bile flow.
