Which type of ostomy is created from the small intestine?

An ileostomy is specifically created from the small intestine, particularly the ileum, which is the last section of the small intestine. This type of ostomy is performed when the colon (large intestine) needs to be bypassed or removed due to conditions such as Crohn's disease, ulcerative colitis, or cancer. In an ileostomy procedure, the ileum is brought to the surface of the abdomen, creating an opening that allows waste to be expelled from the body into an external pouch.

In contrast, a colostomy is formed from the large intestine (colon), which means it functions differently and is indicated for different medical conditions. A urostomy pertains to procedures involving the urinary system and is not linked to the small intestine, whereas a jejunostomy is formed from the jejunum, which is the middle section of the small intestine but distinct from the ileum. This clear differentiation is essential for understanding each type of ostomy and their specific applications in patient care.
