Depending on the manufacturer, the reservoir can hold approximately between 110ml and 300ml of water. This reservoir is squeezed to inject water into the rectum. The regime will be such that participants will be asked to use rectal irrigation daily for two weeks. They will be restricted to not use rectal irrigation for more than once in a day. Every day they can use up to 300ml for irrigation. After two weeks participants can then adjust the number of irrigation days per week as well as volume used for irrigation but not exceeding irrigation therapy more than once a day and not more than 300ml per irrigation. Volume and frequency of rectal irrigation will be recorded by participant in participant journal. This will be used to check their compliance and average weekly irrigation sessions and volume used for satisfactory outcome.",[13],"Device: Rectal Irrigation",{"label":15,"type":10,"description":16,"interventionNames":17},"High-volume rectal irrigation","The high-volume irrigation system consists of an irrigation bag connected to a tube. The water flows into the rectum, either by gravity or by using a pump. Some systems use balloon to hold the device in place during irrigation; others require the user to hold it in place. The mechanism of action is the same for all systems. Participants will start irrigation with 300ml and increase this by 100ml every 2 days until satisfactory defaecation is achieved, or the procedure becomes uncomfortable, up to a maximum of 1500ml. Initial frequency of irrigation is the same as for low-volume irrigation: i.e. once daily for two weeks followed by participant adjustment of number of irrigation days per week as well as volume used for irrigation but no more than 1500ml a day.
