Etymology
the term is a modern medical neologism constructed entirely from greek roots. it follows the precise, descriptive logic of scientific terminology, literally translating to 'the cutting out of the bile bladder'. the first element, 'chole-', refers to bile, the digestive fluid stored in the organ. the second, '-cyst-', specifies the anatomical structure as a sac or pouch. the final combining form, '-ectomy', is a standard suffix in surgery indicating removal. thus, the word's formation is transparent and logical, building the complex medical concept directly from its classical constituent parts.
