What is the definition of a stoma?

A stoma is specifically defined as an opening that is surgically created from the intestine to the outside of the body, often to facilitate the use of a colostomy bag. This medical procedure is commonly performed when a portion of the intestine is no longer functional or needs to be bypassed due to disease, injury, or other medical conditions. The stoma allows for the excretion of waste in a controlled manner, which is collected in the colostomy bag that adheres to the skin surrounding the stoma.

The other definitions presented do not accurately reflect the meaning of a stoma. A temporary opening in the skin might imply a wound or incision, but it does not specify the gastrointestinal connection that characterizes a stoma. A type of wound dressing refers to materials used to cover and protect wounds rather than describing a surgical procedure. Similarly, a method of catheter insertion pertains to devices and techniques used for urinary or other types of catheterization, which is unrelated to the concept of a stoma. Understanding the correct definition of a stoma is crucial for healthcare professionals and caregivers tasked with managing individuals who have undergone this procedure.
