Definition
By Mayo Clinic staffCholecystitis (ko-luh-sis-TIE-tis) is inflammation of the gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, just beneath your liver. The gallbladder holds a digestive fluid called bile that's released into your small intestine.
In most cases, cholecystitis is caused by gallstones that block the tube leading out of your gallbladder. This results in a buildup of bile that can cause inflammation. Other causes of cholecystitis include bile duct problems and tumors.
If left untreated, cholecystitis can lead to serious complications, such as a gallbladder that becomes enlarged or that ruptures. Once diagnosed, cholecystitis requires a hospital stay. Treatment for cholecystitis often eventually includes gallbladder removal.
