Transanal irrigation (retrograde irrigation) is the regular use of water and irrigation equipment with a catheter in the person's home to assist in the emptying of feces in individuals with bowel dysfunction, including fecal incontinence and constipation.
As a bowel stimulant, similar to a laxative - the main difference being that laxatives are commonly thought of as orally administered while enemas are administered directly into the rectum, and thereafter, into the colon.
