Anal irrigation is the process of cleaning the bowels by instilling warm water into the rectum via the anus and then allowing the water to expand, leading to the emptying of the colon. It is also known as transanal irrigation or rectal irrigation. Many studies have proven the effectiveness of the anal irrigation method over conservative bowel management methods such as the use of constipation medicines, manual evacuation, or surgery. Anal irrigation is indicated in people with neurological disorders such as spinal cord injury, multiple sclerosis, Parkinson's disease, Alzheimer's disease, brain tumors, chronic faecal incontinence, chronic constipation, and for bedridden patients and children unable to pass stool regularly. Anal irrigation systems are very useful for persons with a variety of bowel problems, which makes emptying the bowel easier and secure. These systems usually consist of a control unit with a pump, a water bag, and a rectal catheter, which is very flexible to use and convenient to carry.
