Insights
Esophageal foreign body removal in children using a Foley catheter is highly successful with few complications. No single factor significantly impacted success, though more experienced operators showed a trend toward better outcomes.
Area of Science:
- Pediatric Emergency Medicine
- Gastroenterology
- Medical Devices
Background:
- Esophageal foreign body (FB) impaction presents a significant challenge in pediatric emergency care.
- Foley catheter removal is a common, minimally invasive technique for esophageal FB extraction.
Purpose of the Study:
- To identify factors influencing the success rate of Foley catheter-based esophageal FB removal in pediatric patients.
- To explore methods for improving the efficacy of this procedure.
Main Methods:
- Retrospective, cross-sectional analysis of pediatric patients undergoing Foley catheter removal for esophageal FB impaction.
- Evaluation of patient demographics, FB characteristics, procedural details, and operator experience in relation to success rates.
Main Results:
- Foley catheter removal was successful in 81.4% of cases with no reported complications.
- No significant association was found between success rates and patient age, FB type/size, or procedural variables.
- A trend towards higher success rates was observed with increased operator training, though not statistically significant.
Conclusions:
- Foley catheter use for pediatric esophageal FB removal is effective and safe, with a high success rate and low complication incidence.
- The success of esophageal FB removal appears multifactorial, potentially involving interactions between various patient, FB, and procedural elements.
Objective:
This study aimed to determine the factors that affect successful esophageal foreign body (FB) removal using a Foley catheter and to identify methods to increase the success rate.
Methods:
In this retrospective, cross-sectional study, we included pediatric patients who presented with esophageal FB impaction that was removed using a Foley catheter in the emergency departments of tertiary care and academic hospitals. We analyzed the effect of the patients' age, sex, and symptoms; FB type, size, and location; Foley catheter size; complications during FB removal; duration between FB ingestion and removal; operator's years of training; sedation; success rate of FB removal; endoscopy; and patient's posture during FB removal on the success of Foley catheter-based FB removal.
Results:
Of the 43 patients we enrolled, Foley catheter-based FB removal was successful in 81.4% (35/43) but failed in 18.6% (8/43) of patients; no FB-removal-related complications were reported. There was no significant association between the success rate of Foley catheter-based FB removal and any study variable. A higher number of years in training tended to increase the success rate of Foley catheter-based FB removal, although statistical significance was not achieved.
Conclusion:
Children's esophageal FB removal is a practical challenge in the emergency rooms, and using a Foley catheter is associated with a high success rate of the removal and low occurrence of complications. In this study, no single variable was found correlated with the success rate of Foley catheter-based esophageal FB removal in pediatric patients, which may indicate multiple variables interacting with one another to affect the success rate.
