An ostomy appliance comprises a bag for receiving discharged wastes, a stomal orifice in one wall of the bag, a washer (2325) attached to the wall of the bag and having a flat surface intended to face towards the body of the wearer when the appliance is worn. The washer surrounds the orifice. A medical grade adhesive pad (2310) carries a flange (2320) having an inner peripheral rib (2322), and adhesive means (2323) adhesively attaches the bag to the flange. The bag wall (2327) extends inwardly of the inner edge of said washer surrounding said stomal orifice. In use, the outside wall of the rib tends to be kept clean of waste materials by said inner extending bag wall (2331).
