Abstract
Various routines for preparation of the [human] large bowel prior to radiological examination are in use employing a wide range of laxatives, sometimes in combination with colonic lavage. Three laxatives were examined in the present study; castor oil, Dulcodos and X-Prep liquid. Of the 3 preparations examined, X-Prep liquid was found to give the best preparation of the colon in the doses used and was also most acceptable to the majority of the patients, particularly when compared with castor oil. Side effects were encountered with a greatly reduced incidence of griping and colic. It would seem that in the context of the present study, X-Prep liquid is the preferred medium for preparing the bowel prior to radiological examination of the abdomen.
