Water beads ingestion presenting with repeated bowel obstruction in an infant

An infant presented repeatedly with features of transient bowel obstruction 72 hours after unwitnessed ingestion of water beads. At the third presentation 5 days later, he underwent laparotomy and jejunal enterotomy for retrieval of obstructing water bead in the duodenum. Four other water beads were retrieved. Due to persistent obstructive symptoms, he had a relaparotomy on fourth postoperative day. A further obstructing bead at the duodenojejunal flexure was retrieved. Antegrade upper gastrointestinal endoscopy and retrograde endoscopy through the enterotomy were performed to ensure no further retained water beads. The patient progressed well postoperatively and was discharged home 5 days later. This case highlights the challenges involved in the diagnosis and management of water bead ingestion in children. Children under 2 years are at a higher risk of complications and most require intervention. Palpation alone can miss residual water beads at surgery. Endoscopy including intraoperative enteroscopy could be a useful adjunct.
