Plural of cholecystectomy; plural surgical removals of the gallbladder.
From Greek 'chole' (bile) + 'kystis' (bladder) + 'ektome' (surgical removal) + '-ies' (plural marker). Established as standard medical terminology in the late 1800s when this surgery became common.
Gallbladder removal is one of the most frequently performed surgeries worldwide—so doctors needed both singular and plural forms, making 'cholecystectomies' one of the most clinically important compound medical terms in practice.
