The forward end portion of the body is inserted into the bowel, and a rear end portion has a lug (26) with eyes (27) or securing `cable straps` (29) which are applied around the body and the collapsed bowel segment downstream of the bowel opening. To assist in breaking up solid faecal masses the drain tube includes an ultra-sonic device (16) or other means.
