Trapped Esophageal Stent in a Child: An Unusual Complication

Area of Science:

• Gastroenterology
• Pediatric Surgery
• Medical Device Complications

Background:

• Self-expandable metal stents (SEMS) are prone to migration, a common complication.
• While often manageable endoscopically, migrated stents can become trapped between esophageal strictures.
• This case highlights a rare scenario of a pediatric esophageal stent impaction.

Observation:

• A 2-year-old boy presented with a migrated esophageal stent lodged between two esophageal strictures.
• The stent's position presented a unique management challenge due to the dual strictures.

Findings:

• Surgical excision of the proximal stricture allowed for stent removal via right thoracotomy.
• The distal stricture was successfully treated with balloon dilatation.
• The patient recovered well and was discharged on postoperative day 17.

Implications:

• This case underscores the importance of vigilant monitoring for SEMS complications in pediatric patients.
• Early identification of stent migration and impaction is vital for less invasive treatment.
• Failure to detect early complications may necessitate complex surgical interventions.
