EDITORIAL COMMENTS The information provided in this article is of limited value. The authors used the technique that we orig- inally described 1 with the difference that dissection of the intestinal mucosa was done from inside, which in my view is the main reason for the poor results obtained. In our prospective study of 205 patients 60 had a continent catheterizable channel, including an antegrade colonic enema in 20 and a Mitrofanoff channel in 40, and 50 had an artificial device im- planted. Compared with subgroups in the same se- ries in which these conditions were not present no difference was found. The discussion reflects well the experience of the senior author. Salvador Vilar C.
