What does the suffix "-stomy" indicate?

The suffix "-stomy" signifies the creation of an opening, typically in a specific organ or part of the body, to facilitate the passage of waste or other bodily substances. This can involve surgical procedures that result in an artificial opening, such as a colostomy, where an opening is created in the abdominal wall for the discharge of digestive waste, or a tracheostomy, which creates an opening in the windpipe to assist with breathing. This understanding is crucial in medical terminology and practice, as it helps healthcare professionals communicate effectively about surgical procedures and patient care.
