One-Piece Closed Colostomy Pouch — What You Should Know

A one-piece closed colostomy pouch is designed to collect fecal matter from a surgically created colon or large intestine opening. This type of ostomy pouch is commonly used to treat conditions such as cancer, inflammatory bowel disease, or trauma to the colon that result in the need for a stoma.

One-piece closed colostomy pouches are self-contained units with an adhesive baseplate attached to the skin surrounding the stoma and a collection bag that securely seals and contains the fecal output. Unlike a two-piece system, the one-piece pouch does not require a separate flange or barrier, making it easier to apply and remove.

The adhesive baseplate is usually made of a soft, flexible material that conforms to the skin's contours, creating a tight seal that prevents leaks and skin irritation. The collection bag is typically made of a durable, odor-proof material that can hold much fecal matter.

The Benefits of One-piece Closed Colostomy Pouch

Some potential benefits of using a one-piece closed colostomy pouch includes the following:

  • Discreet: One of the critical benefits of a one-piece closed colostomy pouch is its unobtrusive design, which allows patients to go about their daily activities without drawing unwanted attention. The bag can be easily concealed under clothing and is typically not visible through fabric materials.
  • Convenience: A one-piece closed colostomy pouch is easy to use and dispose of, making it more convenient for patients who need to empty or change the bag frequently.
  • Security: The one-piece design can provide added protection against leaks, which can be especially important for patients who lead active lifestyles.
  • Comfort: The adhesive barrier on a one-piece closed colostomy pouch is designed to be gentle on the skin, which can help prevent irritation or discomfort. In addition, using a one-piece closed colostomy pouch can give patients greater confidence and control over their condition, improving their overall quality of life.
  • Hygiene: The closed pouch design can help reduce the risk of infection or odor, which can be concerning for patients with an open colostomy.

What are the Downsides of a One-piece Closed Colostomy Pouch

Some potential downsides of using a one-piece closed colostomy pouch includes the following:

  • Limited visibility: Because the pouch is closed, you cannot see its contents without removing it. This may make monitoring the output difficult and ensure the stoma is healthy.
  • The inconvenience of the disposal: Because the pouch is not designed for reuse, it must be disposed of after use. This may be inconvenient if you are in a public place without access to a restroom. Also, the pouch must be emptied and replaced more frequently than the more extensive, two-piece colostomy pouch system, which can be inconvenient for some patients.
  • Odor: Without a filter, gas and odor can build up inside the pouch, which can be unpleasant and embarrassing.
  • Skin irritation: Some people may experience skin irritation or sensitivity to the adhesive used to attach the pouch to the skin. This can be uncomfortable and require frequent pouch changes or additional skin care.
  • Cost: One-piece closed colostomy pouches can be more expensive than other types, especially if they need to be changed frequently. This can be a burden for people who are on a tight budget or need adequate insurance coverage.


Overall, a one-piece closed colostomy pouch is an excellent medical device for colostomy patients. While it has a few drawbacks, the advantages far exceed them. Patients should work closely with their doctor to determine the best ostomy appliance for their needs and preferences.
