Is there a role for surgery beyond colonic aganglionosis and anorectal malformations in children with intractable constipation?

Abstract

Purpose: The aim of this study was to assess benefit of surgery in the treatment of childhood constipation in children without aganglionosis or anorectal malformations.

Methods: Retrospective chart review and follow-up questionnaire of 19 children (10 girls, age 7.6 +/- 3.9 years) who underwent surgery after colonic and anorectal manometry had documented abnormal motility. Children at the time of manometric evaluation had symptoms of intractable constipation a mean of 5.1 +/- 2.5 years. Follow-up questionnaires were administered to caregivers a mean of 11.4 +/- 9.3 months after surgical intervention.

Results: Proximal colonic abnormalities were seen in 2 patients, abnormalities involving the distal colon and rectosigmoid region in 13 patients, pancolonic abnormalities in 2 patients, and incomplete relaxation of the internal anal sphincter in 2 patients. Surgery led to increase in frequency of bowel movements per week (8.1 v 1.9; P <.005), decrease in soiling episodes per week (2.20 v 4.7; P <.01), and decrease in daily use of medications for constipation (0.8 v 2.3; P <.05). Adverse events included skin breakdown at site of ostomy (9%), fecal incontinence after pull-through procedure (13%), and persistent constipation (4.5%). Parents felt that the symptoms after surgery were completely resolved in 89% of patients.

Conclusions: Surgery may be beneficial in the management children with chronic intractable constipation and documented abnormalities in motility.
