Insights
Superabsorbent polymer bead (SAPBs) ingestion in children can cause serious intestinal obstruction. Management often requires endoscopic or surgical intervention, with fragmentation techniques showing promise in selected cases.
Area of Science:
- Pediatric Gastroenterology
- Toxicology
- Surgical Pediatrics
Background:
- Superabsorbent polymer bead (SAPBs) ingestion presents a significant risk of pediatric intestinal obstruction due to rapid gastrointestinal expansion.
- Existing literature on SAPBs ingestion is limited, primarily consisting of isolated case reports.
Purpose of the Study:
- To retrospectively review cases of SAPBs ingestion in pediatric patients.
- To summarize clinical characteristics and management strategies for SAPBs ingestion.
- To identify diagnostic and therapeutic challenges associated with SAPBs ingestion.
Main Methods:
- Retrospective review of medical records for pediatric patients (<18 years) with SAPBs ingestion (September 2018 - September 2025).
- Collection and analysis of demographic data, clinical presentation, imaging findings, treatments, and complications.
- Evaluation of diagnostic utility of Computed Tomography (CT) and ultrasound.
Main Results:
- Eleven pediatric patients analyzed; median age 1 year 4 months.
- Common symptoms included vomiting, fever, and irritability; 3 patients (27%) had abdominal distension.
- Management varied, including laparotomy with fragmentation, endoscopic fragmentation, and enemas; 5 patients (45%) experienced complications like intestinal obstruction.
Conclusions:
- SAPBs ingestion can lead to significant pediatric morbidity requiring intervention.
- Manual fragmentation during laparotomy can avoid enterotomy in select cases.
- CT and ultrasound are valuable for diagnosis; public awareness and regulation are crucial for prevention.
Abstract:
OBJECTIVES: Ingestion of superabsorbent polymer beads (SAPBs) poses a unique and serious risk of intestinal obstruction in young children due to their rapid expansion within the gastrointestinal tract. Data regarding the ingestion of SAPBs remain scarce, with the existing literature primarily drawn from isolated case reports. This study retrospectively reviewed cases of SAPBs ingestion in pediatric patients treated at our institution to summarize clinical characteristics and share management experience. METHODS: We conducted a retrospective review of medical records for patients aged < 18 years who presented to our hospital due to SAPBs ingestion between September 2018 and September 2025. Demographic information, clinical presentation, imaging findings, treatment modalities, and complications were collected and analyzed. RESULTS: Eleven patients (7 males, 4 females) met the inclusion criteria and were analyzed. The median age was 1 year 4 months. The median time from ingestion to presentation was 12 h (range, 2–48), and from ingestion to symptom onset was 5 h (range, 2–24). The most common presenting symptoms were vomiting (6/11), fever (5/11), and irritability (4/11); abdominal distension was noted in 3 patients (27%). Three patients remained asymptomatic throughout. Computed Tomography (CT) and ultrasound were useful for diagnosis in 5/7 and 2/3 cases, respectively. SAPBs were commonly located in the duodenal ascending segment (n = 2) and ileum (n = 2). Management included laparotomy with transmural fragmentation (3/11), gastroduodenoscopy with intraluminal fragmentation (1/11), gastroduodenoscopy converted laparotomy with fragmentation (1/11), gastroduodenoscopy only (3/11) and enemas only (3/11). Complications included intestinal obstruction (5/11), elevated liver enzymes, anemia, and headache (1 each). CONCLUSION: Ingestion of SAPBs can lead to significant morbidity in children, often requiring endoscopic or surgical intervention. In our small series, for expanded SAPBs accessible during laparotomy, manual fragmentation and advancement into the colon for subsequent transanal expulsion allowed us to avoid enterotomy in selected cases. CT and ultrasound are valuable for diagnosis. Enhanced public awareness and stricter product regulations may help reduce the occurrence of such accidental injuries.
