A medical procedure in which the gallbladder is surgically removed from the body.
After experiencing severe abdominal pain, the doctor recommended a cholecystectomy to remove the gallbladder.
Cholecystectomy → It is formed from "chole" (from Greek "chole", meaning bile) and "cystis" (from Greek "kystis", meaning bladder) and "-ectomy" (from Greek "ektome", meaning excision or removal). The word refers to the surgical removal of the gallbladder, which is the organ that stores bile.
Think of 'bile' ('chole') being stored in a 'bladder' ('cystis') that is being 'removed' ('-ectomy') — that's what cholecystectomy means.
