In the present study, we evaluated the usefulness of the parameters obtained through ARM in children with retentive fecal incontinence (RFI). Materials and methodsChildren with functional constipation, aged 4 to 17years, that underwent ARM were included in the study. ResultsOf the 35 children evaluated, 21 presented with functional constipation and 14 had functional constipation and RFI. The children with both constipation and RFI tolerated greater volumes of air insufflation for triggering the urge to defecate and reaching maximum tolerance of pain, compared with the children that did not have RFI. We identified the cutoff point of 135ml of air as the maximum tolerance sensation for distinguishing children with RFI. ConclusionsMaximum tolerance of pain was the most useful parameter for evaluating RFI in children with functional constipation. ER -
