A colostomy is a surgical procedure to create an opening (stoma) in your abdomen that connects part of the large bowel (colon) to the exterior. This allows the passage of stools and gas through the stoma. Irrigating a colostomy may allow you to have more control over the timing of your bowel movements. It is used less frequently now that pouch systems are more advanced. Talk to your doctor or ostomy nurse if you think this might be a good choice for you. Basically once a day, or once every other day, you irrigate by flushing the colostomy with warm water. To irrigate, you need an irrigation kit, hook, and water-soluble lubricant. Before starting an irrigation program, get specific instructions from an enterostomal or wound-ostomy-continence provider.
