What is Gallbladder and Bile Duct Inflammation?
As parts of your dog’s complex digestive system, the impaired functioning of the bile duct and gallbladder due to inflammation will severely affect digestion and overall health. Gallbladder inflammation can be accompanied by gallstones, and in severe cases, may be a symptom of gallbladder cancer. There is no correlation to a specific breed, and gallbladder and bile duct inflammation is no more likely to occur in either gender. Non-necrotizing inflammation occurs at any age; however, necrotizing cholecystitis is more commonly found in middle-aged and senior dogs.
Your dog’s bile duct transmits bile from the liver and into the gallbladder, where it is stored and disseminated into the intestine. Bile aids in digestion, absorption of fats, and the elimination of wastes. Inflammation of the gallbladder, or cholecystitis, and inflammation of the bile duct, or choledochitis, typically occur in tandem and affect the functioning of the digestive system.Symptoms of Gallbladder and Bile Duct Inflammation in Dogs

A complete blood count will be taken in order to measure for anemia or any white or red blood cell abnormalities, as well as a chemical blood profile in order to measure liver enzymes. A urinalysis will be conducted in order to measure electrolytes, which will be imbalanced if your dog is positively diagnosed with inflammation. A bile acid test will likely be conducted, which does require that your dog fasts for 12 hours. Additionally, x-rays or ultrasound imaging will be utilized in order to obtain images of the digestive system, identify a thickened gallbladder wall detect gas in the bile duct or gallbladder.

Your dog will need IV fluids in order to restore proper fluid and electrolyte balance. Broad-spectrum antibiotics will be utilized in order to manage the inflammation.
