The advantage to a <a title="2-Piece Ostomy Bags" href="https://www.shopostomysupplies.com/c-two-piece-ostomy-bags.html" target="_blank"><span style="font-weight: bold;">two-piece ostomy pouches</span></a> is that it is easier to see how you are placing your wafer, especially for somebody who has some vision issues or has trouble seeing very well. For them, a 2-piece will be more practical &amp; easier because they can look in the mirror &amp; see. I do find that some family members, who are providing stoma care also find that easier to do especially when they are new. When you become a pro at it because you’ve had your stoma for a long time, I do have patients who use a 1-piece tan pouch so they don’t have to see how they are placing it. The biggest benefit to it is getting that good placement of the wafer portion of your pouch.
