A one-piece ostomy system combines the skin barrier and pouch into a single unit. The ostomy bag fixes around the stoma through an adhesive flange. It is the most popular ostomy system, being lightweight and easy to manage.
Advantages of a one-piece ostomy system are:
A one-piece ostomy system is one single unit of pouch and skin barrier. When removing this system, the entire unit has to be removed. A two-piece system has the skin barrier separate from the pouch. In this type, first you have to fix the barrier on the skin around the stoma through an adhesive and then fit the ostomy pouch on to the barrier. When removing a two-piece, the pouch has to be removed first and then the barrier.
Start with peeling one corner of the skin barrier. Push the skin down and pull the barrier up. You can also use an adhesive remover like a wet paper towel soaked in warm water. Dispose of the old pouch into a plastic bag. A closure clip may be kept aside for reuse later.
