Balloon enteroscopy is an emerging technique to allow access to the small intestine for both diagnostic and therapeutic purposes. To date, there have been few published data documenting the safety and efficacy of balloon enteroscopy in small children.

To describe our experience with single-balloon enteroscopy (SBE) in a 37-month-old toddler with occult GI bleeding.

A single case report.

A free-standing, academic children’s hospital in Denver, Colorado.

The patient was a 37-month-old, 13.5-kg toddler with persistent heme-positive stools, severe microcytic anemia, and hypoalbuminemia. Previous workup was significant for eosinophilic inflammation in the antrum and a video capsule study showing erythematous lesions in the small bowel.

An antegrade SBE was performed with the child under general endotracheal anesthesia, with biopsy specimens obtained from identified lesions in the jejunum and ileum.

Complications and successful treatment of symptoms were the primary endpoints.

The procedure was performed successfully in 85 minutes, passing an estimated 200 cm beyond the pylorus, without complications. Identification of the lesions as consistent with eosinophilic enteropathy led to successful treatment with an elimination diet and corticosteroids.

The primary limitation of this study is that it is a single case report. Therefore, it is difficult to make a generalized statement regarding the safety and efficacy of balloon enteroscopy in toddlers of this size.

Antegrade SBE can be a well-tolerated and effective procedure to evaluate occult GI bleeding in children as young as 3 years of age. Further study is needed to better establish safety parameters for balloon enteroscopy in small pediatric patients.
