This article is intended for health-care professionals involved in the management of patients with bowel dysfunction and describes what TAI is and the proposed method of action. It also considers the latest evidence related to the safety and efficacy of TAI. There is now a potentially overwhelming range of equipment available on prescription to deliver this treatment. The factors to consider in the appropriate selection of equipment for individual patients will be considered, alongside an algorithm for the selection of equipment to aid health professionals with this choice. ransanal irrigation (TAI), also known as Mechanism of action Michelle Henderson, Bowel Specialist Nurse; rectal irrigation, is used throughout the Proposed mechanisms of action include simple Linda Tinkler, Academic TUK as a treatment for bowel dysfunction, mechanical washout in the recto-sigmoid colon, Research Nurse; Yan and it has recently received National Institute increased colonic peristalsis stimulated by the Yiannakou, Lead Consultant for Health and Care Excellence (NICE) approval washout or a combination of these (Christensen Neurogastroenterologist, for treating both constipation and faecal and Krogh, 2010).

In patients with idiopathic using either a rectal catheter or a cone. When constipation, only 59% of the recto-sigmoid the catheter or cone is removed, the water is colon emptied; however, this was sufficient for expelled, along with the contents of the rectum, patients to feel benefit from TAI. For all 19 patients sigmoid colon and possibly descending colon. in this study, bowel function and quality of life TAI can re-establish controlled bowel evacuation, improved, reinstating predictability and control enabling the user to choose the time and place of over defaecation (Christensen et al, 2003). evacuation (Emmanuel, 2010).

TAI is an effective treatment for chronic constipation that has proven refractory to medical management (Emmett et al, 2015). Chronic constipation is a common condition, occurring in 14% of the community, particularly in women, and increasing in prevalence as the population Image supplied to the authors by Coloplast ages (Suares and Ford, 2011). Patients with obstructed defaecation syndrome, functional defaecation disorder, chronic idiopathic constipation or constipation-predominant irritable bowel syndrome can benefit from TAI (Emmett Before transanal irrigation After transanal irrigation The bowel is loaded with stool The descending colon and et al, 2015). Recent NICE guidance (2018)— rectum are empty of stool focussing on the Coloplast Peristeen system— recognised that TAI can reduce constipation Figure 1.
