A one-piece ostomy system has the pouch and wafer combined into a single unit, while a two-piece ostomy system has a separate pouch and wafer that attach together. Both systems are used to collect output from a stoma.
In a two-piece ostomy system, the pouch may be changed without removing the wafer, depending on the product design. One-piece and two-piece systems can vary by pouch type, wafer style, opening size, convexity, closure method, and accessory compatibility, so product details should be reviewed carefully before ordering.
