Collection systems for your colostomy

Two types of collection system are used, regardless of the brand of equipment you use: a one-piece or a two-piece system. 

The collection system always consists of

  • A collection pouch: a colostomy pouch is a sealed bag with a carbon filter that neutralises intestinal gases and odours. The pouch has to be replaced once it is half full. You can choose between a transparent pouch or one made from a discreet, non-transparent grey or skin-coloured material.
  • A protective flange which is applied to the skin around the stoma. 

Immediately after the operation a two-piece system will be used with a transparent pouch, which can be emptied, to facilitate the care process. The use of a drainable pouch is recommended because stools are usually very loose following the operation.
