the gallbladder is an organ of the digestive system. contained in the abdominal cavity, it serves as a reservoir for the bile secreted by the liver, which empties it via the common bile duct into the duodenum (initial part of the small intestine). bile participates in digestion.

ablation of the gallbladder or cholecystectomy is indicated in case of gallbladder stones (symptomatic stones). the intervention prevents recurrences and complications.
