After an ostomy surgery, you get different types of pouching
systems that you can take home. These pouching systems work for different kinds
of stomas. After getting home, you can try each of the systems to figure out what
works best for your stoma.

One-piece and two-piece ostomy pouching systems
There are two types of ostomy pouching system from the
perspective of pouch attachment with the stoma. These two pouching systems are
one-piece and two-piece ostomy pouching system.
Both of the pouching systems consist of a skin barrier and a
pouch. Skin barrier is the part which has a layer of adhesive. This part has to
be attached to the persitomal skin, the skin around the stoma. Its main purpose
is to prevent leakage of stomal output while ensuring protection of the
peristomal skin, which is quite susceptible to irritation when exposed to
stomal output. The pouch is a bag which collects output from the stoma.
One-piece pouching system

This pouching system has a skin barrier which is permanently
attached with the bag. It means that if you are going to have to remove the
bag, you are going to have to detach the barrier from the skin. This pouching
system is very simple and very easy to apply; i.e. just peel the protective
cover from the skin barrier and attach it with the persitomal skin. The best
thing about this pouching system is that it lies flatter than other types of
pouches, meaning that you can conceal the pouch more easily.
Two-piece pouching system

A two-piece pouching system is more versatile because it has
a pouch and a barrier as two different entities. These two parts are connected
together by the means of a plastic ring, or flange. The major advantage of this
pouching system is that you don’t need to remove the barrier in order to empty
or replace the bag. Thus, it is the perfect pouching system if you need to
change the bag more frequently than the barrier.
Drainable and closed ostomy pouches
From the perspective of bag usability, there are two types
of pouches; i.e. drainable and closed ostomy pouches. Each of these pouches has
its own set of advantages.
Drainable ostomy pouches

These pouches have a clamp or an integrated closure that
allows you to empty the bag when it is filled. But make sure that you are not
waiting for the bag to be completely filled. The best practice is to empty the
bag when one-third of it is filled. These bags are typically needed in case of
urostomy.
Closed pouches
These bags need to be disposed rather than emptied. You can
use these pouches when your stomal output is not quite frequent. All you have
to do is to remove the bag one it is filled and throw it away.
