What does the suffix "-stomy" indicate?

The suffix "-stomy" indicates the creation of an artificial opening in the body. This term is commonly used in medical contexts where a surgical procedure is performed to form an opening that connects an internal organ to the outside of the body, such as in colostomy or ileostomy procedures. These artificial openings allow for the diversion of bodily fluids or waste, providing a necessary means for patients who may have had portions of their digestive system removed or altered due to disease, injury, or other medical conditions. This understanding is crucial for interpreting medical terminology and procedures related to surgeries that entail establishing such openings.
