“We’ll need to perform a ‘laparotomy’”. “Don’t mess with that, that’s the ‘pancreas’.” “Was that the ‘vagus’?” Every day within the surgical field, we rely on a dense, efficient language that conveys complex meaning in a short gasp of air and flick of the vocal cords. But where do the meanings of these words come from? Why have these particular combinations of sounds come to signify such complex ideas? These terms may feel modern and technical, but they are rooted in some of the earliest attempts to understand the human body. This talk will discuss the etymological origin of many common words within general surgery, delving into their roots in ancient languages such as Latin, Greek, Old English, and Proto-Indo-European. Many of these words have intuitive origins, such as “bronchus” meaning “windpipe”. But there are many others that have remarkable and unexpected origins, such as “artery” which also means “windpipe” (as these vessels were found empty and full of air on the earliest autopsies), and “duodenum” which means “twelve fingers” (as it was commonly twelve fingerbreadths long when examined by the ancient Greek physician Herophilus). The overall aim of this presentation is to allow the listener to learn of, and appreciate, the deep and rich ancestry of the words we use inside and outside of the operating theatre, with their meanings carried through millennia based on careful observations made by ancient humans. Common cases within general surgery will be discussed, with pertinent words related to presentation, workup, operation, and recovery selected for etymological study. By understanding where our surgical language comes from, we gain more than trivia: we deepen our connection to the craft of surgery itself, sharpen our conceptual understanding of anatomy and disease, and recognize that each word we speak in and out of theatre carries with it the accumulated knowledge of generations who operated and observed before us.
