The combining form -ectomy is used like a suffix meaning “excision,” or "surgical removal." It is often used in medical terms, especially in surgery.The form -ectomy ultimately comes from the Greek ektomŧ, meaning “excision.” It is equivalent to the combination of ec- (from the Greek ek, “out”) and -tomy  from the Greek ٴdzḗ, “a cutting”. So, -ectomy has a literal sense of “a cutting out of”—that is, “an excision.”Related to -ectomy and -tomy are the combining forms -tome, -tomous, and tomo-.
