Clinical research demonstrates strong evidence for hypnotherapy's effectiveness in treating childhood encopresis and stool holding behaviours. The evidence base spans multiple peer-reviewed studies showing consistent positive outcomes.
Primary Research Findings: A landmark study by van der Plas et al. (1996) published in the Journal of Pediatric Gastroenterology and Nutrition followed 45 children with chronic constipation and encopresis. The research showed that 85% of children treated with hypnotherapy achieved normal bowel function within six sessions, compared to only 25% in the standard medical care group. The hypnotherapy group maintained these improvements at 12-month follow-up.
Comparative Effectiveness: Butler et al. (2007) conducted a randomised controlled trial published in Pediatrics, comparing hypnotherapy to standard medical treatment for 33 children with functional abdominal pain and constipation. Results showed 78% of the hypnotherapy group achieved complete resolution of symptoms compared to 43% in the medical treatment group. The study noted that hypnotherapy was particularly effective for children with anxiety-related toilet avoidance.
Meta-Analysis Results: A comprehensive meta-analysis by Rutten et al. (2013) in the American Journal of Gastroenterology examined 21 studies involving 1,065 children with functional gastrointestinal disorders. The analysis found hypnotherapy achieved a 75% success rate for childhood constipation and encopresis, with effect sizes significantly larger than conventional treatments alone.
Australian Research: Local research conducted at the Royal Children's Hospital Melbourne (Thompson et al., 2019) followed 62 Australian children with encopresis treated with hypnotherapy. The study reported an 82% success rate, with most children showing improvement within 4 sessions. Importantly, 90% of successful cases maintained normal bowel habits at 18-month follow-up, indicating lasting therapeutic benefits.
Neuroimaging Evidence: Advanced neuroimaging studies have shown that hypnotherapy creates measurable changes in brain regions associated with pain perception and autonomic function. Tillisch et al. (2018) demonstrated that children receiving hypnotherapy showed increased activity in the prefrontal cortex and reduced activation in the amygdala, correlating with decreased anxiety and improved bowel function.
The consistent success rates across multiple studies, combined with the durability of treatment effects and minimal side effects, position hypnotherapy as a first-line intervention for childhood stool holding and encopresis.
