Two-Piece Systems
The wafer/skin barrier and the collection pouch are separated. The wafer can then stay attached to the abdomen while a new collection pouch is added. This can mean less irritation to the skin. The pouch and wafer are connected and held together with a plastic, snap on pressure ring, similar to the snap on lid of a kitchen storage container.
One-Piece Systems
The adhesive skin barrier and the collection pouch are integrated as a single, one-piece appliance. The advantage is ease of use. But the adhesive barrier and entire appliance must be removed and replaced.
Whether one or two-piece, ostomy pouching systems are available as closed or drainable appliances. A closed pouch is a single use collection pouch which is removed and disposed of when full. Conversely, a drainable pouch can be emptied when full, allowing longer use of each appliance.
The choice of a particular type and style of pouching system is a personal decision which involves consideration of lifestyle, physical dexterity, ostomy type, and simple individual preference. Do not hesitate to experiment with a number of different options until you find a pouching system which meets your needs.
