Which surgical procedure creates an opening from the ileum through the abdominal wall to function as an anus allowing stool to bypass the entire large intestine?

• A. Ileostomy
• B. Hepatocytes
• C. Hyperbilirubinemia
• D. Impaction

Answer: (A)

An ileostomy creates a surgical opening in the abdomen that connects the ileum to the outside, functioning as an outlet for stool. By bringing the end of the small intestine to the abdominal wall, stool exits the body without passing through the large intestine and rectum, effectively bypassing the entire colon. This is done when the colon can’t process feces due to disease or removal, and the output is usually more liquid because the colon’s water absorption is avoided. The other terms aren’t procedures: hepatocytes are liver cells, hyperbilirubinemia is high bilirubin in the blood, and impaction is a hardened stool problem, not a surgical intervention.
