What does the term 'ostomy' refer to in medical procedures?

The term 'ostomy' specifically refers to the creation of an opening in the body for the purpose of expelling waste. This procedure is commonly performed for patients who have had certain surgeries affecting their digestive or urinary systems, such as colostomies or ileostomies. During these procedures, a segment of the bowel is brought to the surface of the skin, allowing waste to exit the body through this new opening. The focus is on establishing a passage for bodily functions that may have been disrupted due to illness, injury, or surgery.

In the context of medical terminology, other terms such as 'ectomy' denote the removal of tissue and 'plasty' refers to surgical repair, while imaging techniques pertain to diagnostic procedures rather than surgical interventions. Understanding the specific meaning of 'ostomy' helps clarify its purpose and application in medical settings.
