Chronic vomiting and feeding difficulties are common in young children and have a negative physical and psychosocial impact for patients and families. Currently there is no straightforward treatment algorithm for these issues, and management often involves multiple medication trials and procedures. Intrapyloric botulinum toxin injection has been proposed as a treatment for nausea and vomiting in adults, but there is minimal prior research on use in children and no prior research on use in children with feeding disorders. The aims of this study are: (1) to determine the efficacy of intrapyloric botulinum toxin injection for reducing gastrointestinal symptoms in children, (2) to determine the efficacy of intrapyloric botulinum injections for improving feeding outcomes in children, and (3) to define predictors of response to intrapyloric botulinum toxin injection.
