Insights
Pediatric foreign body ingestion or aspiration requires specific imaging guidelines. This document outlines appropriate imaging choices for ingested or aspirated foreign bodies (FBs) based on clinical suspicion and prior imaging results.
Area of Science:
- Pediatric Radiology
- Medical Imaging Guidelines
- Emergency Medicine
Background:
- Foreign body (FB) ingestion or aspiration is a frequent cause of pediatric emergency department visits.
- Timely and accurate diagnosis is crucial for effective management of pediatric foreign bodies.
Purpose of the Study:
- To provide evidence-based imaging recommendations for pediatric foreign body ingestion and aspiration.
- To outline appropriate imaging strategies based on clinical presentation and initial findings.
Main Methods:
- Development of three variants based on clinical suspicion (ingested vs. aspirated FB) and initial imaging results.
- Systematic analysis of medical literature using established methodologies like GRADE.
- Expert consensus and the RAND/UCLA Appropriateness Method for guideline formulation.
Main Results:
- Variant 1 (suspected FB): Radiographs of the neck, chest, abdomen, and pelvis are generally appropriate; low-dose noncontrast chest CT may be used for radiolucent FBs.
- Variant 2 (ingested FB, negative initial radiographs): Chest CT without contrast is usually appropriate; fluoroscopic esophagram or CT abdomen/pelvis may be considered. Abdomen ultrasound is helpful for water bead ingestion.
- Variant 3 (aspirated FB, negative initial radiographs): CT chest without contrast is usually appropriate; decubitus chest radiographs and fluoroscopy are generally not appropriate.
Conclusions:
- The American College of Radiology Appropriateness Criteria provide a framework for selecting optimal imaging in pediatric FB cases.
- Imaging choices should be tailored to the suspected FB location and patient presentation.
- These guidelines aim to ensure appropriate use of imaging resources in pediatric foreign body emergencies.
Abstract:
Ingestion or aspiration of foreign bodies (FBs) is a common reason for pediatric emergency department visits. In this document, three variants were developed. In Variant 1 (suspect ingested or aspirated FB, initial imaging), neck, chest, abdomen, and pelvis radiographs are usually appropriate to identify the presence and location of a swallowed or inhaled FB. Low-dose noncontrast chest CT may also be appropriate when there is high suspicion for radiolucent FB. In Variant 2 (suspect ingested FB, initial radiographs negative, next imaging study), chest CT without contrast is usually appropriate, although fluoroscopic esophagram or CT abdomen and pelvis may be appropriate. If known ingested water beads, abdomen ultrasound may be helpful. In Variant 3 (suspect aspirated FB, initial radiographs negative, next imaging study), CT chest without contrast is usually appropriate while decubitus chest radiographs and fluoroscopy studies are usually not appropriate. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.
