Irrigation is a flushing of the colon. It is possible, with the correct diet, to go 2 full days without any output. It eliminates leaks, irritated skin, and other problems associated with a colostomy. Not everyone qualifies, as you must have some descending colon left and it must be healthy. Most cancer survivors qualify. I suggest that if you have a colostomy, you ask your doctor or nurse if you are a candidate for irrigation. It's a life changer!
