. Pouching systems are most commonly associated with colostomies, ileostomies, and urostomies. Pouching systems usually consist of a collection pouch, a barrier on the skin, and connect with the stoma itself, which is the part of the body that has been diverted to the skin. The system may be a one-piece system consisting only of a bag or, in some instances involve a device placed on the skin with a collection pouch that is attached mechanically or with an

Surface barriers

Ostomy barriers sit on the skin and separate the ostomy pouch from the internal conduit. They are not always present. These barriers, also called flanges, wafers, or baseplates are manufactured using

resistance * ease of removal. In addition, barriers with adhesive border can provide additional security that the system stays in place. Using a barrier film spray before applying a new flange will improve adhesion, soothe irritated skin and protect the skin from irritation. A barrier may last between one to many days before it needs to be replaced; this is highly dependent on the individual's lifestyle, ostomy type, and anatomy.

Pouches

The method of attachment to the barrier varies between manufactures and includes permanent (one-piece), press-on/click ("

The two-piece arrangement allows pouches to be exchanged without removing the wafer; for example, some people prefer to temporarily switch to a "mini-pouch" for swimming, intimate and other short-term activities. Mini-pouches are suitable for minimum usage only. Pouches can be divided into two basic types: open-end (drainable) and closed-end (disposable). * Open-end pouches have a resealable end that can be opened to drain the contents of the pouch into a

, and an airtight pouch will collect this and inflate. To prevent this some pouches are available with special charcoal filtered vents that will allow the gas to escape, and prevent ballooning at night. Some odor can be expelled through the charcoal filter especially if sufficient deodorant is not used in the pouch. Pouch covers are helpful to disguise the plastic pouch when it is exposed when reaching or other physical activity. These are usually made of cloth and can be decorative or plain to blend in with clothing. Various sources stock sizes for most manufacturers pouches. There are flexible elastic pouch belts available for extreme physical activity but some of these require the pouch to be worn sideways so it does not fill properly and the tight fit causes pancaking of the effluent.

Impact

Ostomy systems often take some time for a person to adjust to, including requiring time to learn how to use them and change the pouch, as well as psychologically adjust. The time taken to adjust may last for more than a year. Because of embarrassment or stigma associated with an ostomy system, a person who has an ostomy system can experience
