Colorectal surgery

Colorectal surgery is a field in medicine, dealing with disorders of the rectum, anus, and colon. The field is also known as proctology, but the latter term is now used infrequently within medicine, and is most often employed to identify practices relating to the anus and rectum in particular. The word proctology is derived from the Greek words πρωκτός proktos, meaning "anus" or "hindparts", and -λογία -logia, meaning "science" or "study".
