An end stoma is defined as which configuration?

• A. Two openings on the abdomen.
• B. A loop stoma with mucus fistula.
• C. A stoma that reattaches internally.
• D. One stoma with one opening.

Answer: (D)

An end stoma is a single exteriorized end of the bowel. After diverting the bowel, the proximal portion is brought to the abdominal surface to make one opening, while the distal portion remains inside the abdomen (often left as a mucous fistula or closed later). This creates only one stoma opening on the abdomen.

This differs from a loop stoma, where a loop of bowel is brought to the surface and creates two openings: one for drainage from the proximal end and another for the distal mucous fistula. A configuration that reattaches internally would not present as an external stoma with a surface opening. So, the defining feature is a single stoma opening.
