Colostomy bags come in many shapes and sizes, but there are two main types:
• One-piece bags that attach directly to the skin barrier.
• Two-piece bags that have a detachable skin barrier and bag. Other options include open-ended or disposable bags and closed or non-disposable bags. Some bags come with a filter to remove odors and vent gas. This prevents the bag from expanding, detaching from the abdomen, or bursting.
The patient should ask their healthcare team about which type of colostomy bag they will use.
