A tube, called a speculum, is inserted into the rectal canal. Attached to the speculum are two tubes, one for the clean water and one for the waste to be released out of the colon. Water is introduced slowly and gently to hydrate and stimulate the colon. Then the drain is opened and you get to release the fecal matter along with the water. During the release, if you allow me, I massage your abdomen to help facilitate the release. This can be very soothing.
