High fiber diet versus polyethylene glycol in management of chronic constipation in children with cerebral palsy: A randomized controlled trial.

Background: Constipation is one of the most common gastrointestinal symptoms in patients with cerebral palsy. This study was conducted with the aim to compare the efficacy of a high fiber diet and polyethylene glycol in the management of chronic constipation in children with cerebral palsy.

Methodology: An open-label randomized controlled trial was conducted in the Department of Pediatrics of a tertiary care hospital in Northern India among cerebral palsy children aged 1-6 years having chronic constipation. Seventy children were enrolled in the study (35 in each group). Group A children received high fiber diet as per the diet chart prepared by the dietician. Group B received polyethylene glycol (0.5-1 g/kg/day) for a period of three months. At the end of four weeks and three months, all children were assessed for clinical improvement and both groups were compared in terms of stool frequency, consistency of stool, fecal incontinence, palpation of hard stool per abdomen, blood in stool, pain on defecation and overall satisfactory outcome. Satisfactory outcome was defined as defecation > two times weekly, soft stool, no pain on defecation, no palpation of hard stool on abdominal examination, no fecal incontinence, and no blood in stools. Children were also assessed for any adverse effects.

Results: Baseline parameters and GMFCS were comparable in the two groups. Both group patients showed significant improvement in symptoms of constipation at the end of four weeks and three months compared to baseline. However, there was no significant difference between the two groups in terms of satisfactory outcome and parameters like frequency of stool, consistency of stool, palpation of hard stool, fecal incontinence, and blood in stools.

Conclusion: A high fiber diet can be considered a good alternative to polyethylene glycol for the management of chronic constipation in children with cerebral palsy.
