Chronic and occult stool retention: a clinical tool for its evaluation in school-aged children.

Abstract

A scoring method was developed to assess severity of stool retention using plain abdominal radiographs. To determine whether the technique was clinically valid in identifying chronic stool retention, the method was used to evaluate films taken of children with known stool retention before and after therapy. The method showed significant statistical differences between symptomatic pre-therapy films and controls and between pre- and post-therapy films of treatment "successes." No significant differences were found between pre- and post-therapy "failures." Use of radiographs is not a substitute for careful history taking and examination, but this scoring method for evaluating stool retention can be recommended prior to more extensive, invasive investigations in children presenting with functional abdominal complaints.
