Which stoma involves two ends brought through the abdominal wall to create two openings?

• A. Loop stoma
• B. End stoma
• C. Continent stoma
• D. Double-barrel stoma

Answer: (D)

Two ends of the divided bowel are brought out to the skin, creating two separate openings. That’s what defines a double-barrel stoma. You see two external stoma openings side by side, each serving its own limb of bowel. This differs from a loop stoma, where a loop of bowel is brought out and produces a single skin opening with two lumens inside (proximal and distal) rather than two distinct openings. End stomas involve one opening for the end of the bowel, leaving the other part inside. Continent stomas form a reservoir with a catheterizable channel rather than two external openings. So the two external openings through the abdominal wall describe a double-barrel stoma.
