Bowel obstruction related to hydrogel beads.
BACKGROUND: Bowel obstruction due to accidental ingestion of foreign objects occurs rarely in children because 80 to 90% of the objects can pass freely through the gastrointestinal tract.
CASE REPORT: We report a case of a 14-month-old infant who presented bowel obstruction caused by the ingestion of hydrogel beads (sodium polyacrylate). Hydrogel beads are used as sensory and didactic toys that can increase their initial size 200 to 400 times by liquid absorption. An abdominal X-ray was perfomed in anteroposterior supine projection, where a round filling defect at the loop of the right flank was detected; this came to our attention because hydrogel beads are usually radiolucent. The diagnosis was established by abdominal ultrasound where free intraperitoneal fluid was reported with data of small bowel pseudo-obstruction by foreign objects. Conservative treatment was prescribed, finding persistence of increased abdominal perimeter, so an enterotomy was performed for their removal; finding impacted hydrogel beads 30 centimeters from the ileocecal valve.
CONCLUSIONS: Hydrogel beads are dangerous for the pediatric population. The evolution of the patient was favorable thanks to the knowledge of the foreign objects ingested. The expectant behavior that had to be executed, stands out because we had no knowledge as to the maximum size of the hydrogel in the gastrointestinal tract.
