| In a two-piece system, the ostomy pouch and skin barrier are separate. |
 |
| Parts of a two-piece system |
- Pouch — Bag that collects stool or urine
- Skin barrier — Adhesive part that fits around the stoma to protect the skin. (Some skin barriers include a tape border to help hold the barrier in place.)
- Flange — plastic ring on both the pouch and skin barrier that provides a secure attachment. To work, both flanges must be the same size and be from the same product family.

| Advantages of a two-piece system |
- The pouch can be removed without removing the skin barrier.
- Because it is separate from the pouch, the skin barrier can be more easily positioned around the stoma.
