Intra-rectal Botulinum Toxin Injection for Intractable Non-retentive Fecal Incontinence in Children - an Open Label Pilot Study

Background: Fecal Incontinence (FI) is a frustrating and prevalent GI condition with profound social implications and a marked effect on quality of life. Treatment options are limited for children whose FI is not secondary to constipation (overflow incontinence), and they are defined as having non-retentive fecal incontinence (NRFI). Rectal botulinum injections (RBI) have recently shown promise for the treatment of FI in adults, following a large, randomized placebo-controlled trial, but no data exists regarding efficacy in children. Objectives: To evaluate the efficacy and safety of RBI in children with non-retentive fecal incontinence. Methods: A prospective open-label pilot study. Children with intractable NRFI will be screened using anorectal manometry and a colonic transit study. Eligible patients will receive one course of RBI and data regarding FI frequency will be prospectively collected during a 15-week period. Significance: New treatment options for children with intractable fecal incontinence are highly in need. The current study aims to introduce a new treatment modality into pediatric research and patient care.
