Water beads: Expanding toy and ‘new’ problem for paediatric surgeons and community

Background and Study Aims

Water beads made from superabsorbent polymers can lead to bowel obstruction, which can sometimes be fatal. This article aims to highlight the dangers of such toys and to propose an innovative, safe and effective approach to diagnostic and therapeutic management.

Patients and Methods

We report two cases of children with intestinal obstruction following the ingestion of products based on superabsorbent polymers. They were diagnosed and treated in two different centres using varying techniques.

Results

We compare our experiences with the few cases reported in the literature. Since water beads are radiolucent, ultrasound or CT scans are crucial for diagnosis. As in one of our cases, radiography of the upper gastrointestinal tract with contrast can be very helpful. Laparotomy with enterotomy is the main surgical approach reported in literature to extract the water spheres. We report two cases managed using a minimally invasive approach, and one of them is the second one described in the literature, treated endoscopically.

Conclusions

Water beads pose a potential danger to children, making it necessary to limit the sale of this type of toy. We offer a management flowchart based on our experience and evidence from the literature.
