Letter to Editor Comments on: Antegrade continence enema treatment can lead to proximal colonic dilation while preserving motility in children with constipation

Topic overview

We read with interest the retrospective study by van der Zande and colleagues [1] evaluating colonic motility and anatomy in 70 children treated with antegrade continence enema (ACE). The authors report proximal colonic dysmotility in 6% and proximal dilation in 20% of patients with paired contrast enema (CE) data, with longer ACE duration as a contributing factor. This work addresses an important clinical question. However, we wish to raise three methodological considerations.
