What does the suffix "-ostomy" refer to?

The suffix "-ostomy" refers to creating an opening, particularly in a surgical context. This term is commonly used in medical procedures where a new passage is formed—for example, in surgeries like colostomy or tracheostomy, which involve creating openings to allow for waste elimination or respiration, respectively. The focus is on establishing a new, controlled opening in the body, making this the accurate interpretation of the suffix. Understanding the implications of surgical terminology is essential for medical professionals, particularly those involved in procedures that necessitate the formation of new pathways in the body.
