Etymology: Proctocolectomy is a plain technical compound, built in modern medical English from three Greek-derived parts. "Procto-" comes from Ancient Greek "prōktós", meaning anus or rectum, "colo-" comes from the combining form of Latin "colon", and "-ectomy" comes from Ancient Greek "ektomḗ", meaning a cutting out. Put together, the name describes the surgical removal of the rectum and the colon. The Greek roots are old, but the compound itself was assembled from them in modern medicine, not in antiquity. Ancient Greek speakers had "ektomḗ" for cutting out something, and "prōktós" for the lower bowel, but they never combined these into a word for removing the whole large intestine. The term belongs to the vocabulary of modern surgery, where surgeons naturally coined names by joining classical elements.
