Bowel obstruction related to hydrogel beads

Area of Science:

• Pediatric Gastroenterology
• Toxicology

Background:

• Bowel obstruction from foreign body ingestion is rare in children, with most objects passing naturally.
• Hydrogel beads, commonly found in toys, pose a unique risk due to significant expansion upon liquid absorption.

Observation:

• A 14-month-old infant presented with bowel obstruction after ingesting hydrogel beads.
• Radiolucent hydrogel beads were unexpectedly detected on X-ray as a filling defect.
• Abdominal ultrasound revealed small bowel pseudo-obstruction and free intraperitoneal fluid.

Findings:

• Surgical intervention (enterotomy) was required for impacted hydrogel beads located 30 cm from the ileocecal valve.
• Conservative management failed to resolve the obstruction, necessitating surgical removal.
• The beads had expanded significantly within the infant's gastrointestinal tract.

Implications:

• Hydrogel beads represent a significant danger to the pediatric population.
• Awareness of hydrogel bead ingestion and their potential for rapid expansion is crucial for timely diagnosis and treatment.
• Further research is needed on the maximum size hydrogel beads can reach in the GI tract to guide clinical management.
