What does a colostomy specifically create?

A colostomy specifically creates an opening in the abdomen. During this surgical procedure, a portion of the colon is brought through the abdominal wall to create a stoma. The stoma is an artificial opening that allows for the diversion of stool from the intestines to the outside of the body, usually into a colostomy bag. This is necessary when a portion of the colon is diseased or has been removed, or when there is a blockage.

The correct understanding of what a colostomy entails helps clarify the purpose and implications of the procedure in the context of gastrointestinal surgeries and the management of various medical conditions, such as colorectal cancer or inflammatory bowel disease.
