This retrospective study of 549 pediatric patients demonstrates that point-of-care ultrasound performed by emergency physicians using broader clinical criteria achieves 100% sensitivity for detecting intussusception at early stages (mean 11.7h symptom duration). Early detection enabled successful air enema reduction in 97% of cases.

Background: This study aimed to verify the usefulness of point-of-care ultrasound (POCUS) performed by pediatric emergency physicians for detecting intussusception at an early stage.
Methods: This retrospective study included 1-month- to 6-year-old children with clinically suspected intussusception, who underwent POCUS in the pediatric emergency department between December 2016 and February 2018. The criteria for performing POCUS were set to broader standards: presenting any one of intermittent abdominal pain/irritability or bloody stool, or ≥ 2 symptoms among nonspecific abdominal pain/irritability, abdominal mass/distension, vomiting, or lethargy. POCUS results were interpreted and categorized as "negative" or "suspicious," and a radiologist performed confirmatory ultrasound in "suspicious" cases.
Results: We analyzed 575 POCUS scans from 549 patients (mean age, 25.5 months). Among the 92 "suspicious" cases (16.0%), 70 (12.2%) were confirmed to have intussusception. POCUS showed 100% sensitivity, 95.6% specificity, and 97.8% accuracy. Patients with confirmed intussusception were mainly diagnosed in the early stages, with a mean symptom duration of 11.7 h, and most patients (97.1%) were treated successfully via air enema reduction. Compared to the non-intussusception group, the intussusception group had more intermittent abdominal pain (P < 0.001), but less vomiting (P = 0.001); the other clinical features showed no intergroup differences.
Conclusion: POCUS performed using the criteria set to broader standards by pediatric emergency physicians may be useful for detecting intussusception at an early stage, which may present with obscure clinical symptoms.
