Which statement best describes a double-barrel stoma?

• A. It has two distinct stomas.
• B. Loop stoma has single opening.
• C. Involves removal of the bowel.
• D. Always located in RLQ.

Answer: (A)

A double-barrel stoma is defined by bringing two ends of the divided bowel to the abdominal surface as two distinct openings. One end becomes the proximal stoma that drains stool, while the other end forms a distal mucous fistula. That pair of separate skin openings is what distinguishes a double-barrel from other stoma types.

This concept helps differentiate it from a loop stoma, which is created by bringing a loop of bowel to the surface to form a single skin opening with two lumens inside the bowel but only one skin opening. The double-barrel setup isn’t about removing bowel, but about how the bowel is divided and exteriorized. The location on the abdomen isn’t fixed to the right lower quadrant; it depends on the surgical plan. Double-barrel stomas can be temporary to divert fecal flow and protect a distal anastomosis, with the distal end often managed or closed later as healing allows.
