RESUMO
Here is presented a study concerning a hundred children with encopresis, aged from three to twelve years old, controlled for eleven years, so that the period of its evolution can be determined. We have contrasted the data with that obtained by other authors referring to different parameters: pregnancy, delivery, neonatal pathology, etc. We have compared the study of the prediction concerning the time of its evolution, and we have only found two citations in the looked-up bibliography. We have concluded that this time of evolution will be the more shortened when it is a secondary encopresis, there is good scholastic performance, there aren't any disturbances in the EEG, when the dark enema is normal, because the C1 in the Goodenough test is bigger, and so is the percentage in the Raven test and when there is no feeling of guilt, jealousy or introversion.
