Flat stoma bags have a flat adhesive base that sticks directly to the skin and are suitable for stomas that stick out (protrude) from the abdomen. Convex stoma bags have a slightly curved or domed adhesive base that helps press gently around the stoma, making them better for stomas that are flush with or below the skin level to improve seal and prevent leaks.
