It is a treatment for persons with bowel dysfunction, including fecal incontinence and/or constipation (especially obstructed defecation). The impact of transanal irrigation varies considerably. Some individuals experience complete control of incontinence, and other report little or no benefit.[1] Evidence show this treatment can be considered for children as well.[2][3]
When diet and medication has proven ineffective, transanal irrigation is used.[1][4]
