Insights
Self-expanding esophageal stents offer promising results for pediatric strictures. Biodegradable stents resolved peptic strictures, while metal stents increased asymptomatic periods for caustic strictures.
Area of Science:
- Pediatric Gastroenterology
- Interventional Endoscopy
Background:
- Caustic and peptic esophageal strictures in children often necessitate repeated dilations, posing anesthetic and esophageal trauma risks.
- Esophageal stent placement presents a potential advancement for managing these complex pediatric cases.
Observation:
- A case series involving three pediatric patients with esophageal strictures (one caustic, two peptic) treated with self-expanding stents.
- Utilized a nitinol-covered metal stent for the caustic stricture and biodegradable stents for the peptic strictures.
Findings:
- The patient with a caustic stricture required two metal stents, and while further dilations were needed post-removal, the asymptomatic period extended.
- Biodegradable stents in peptic stricture patients eliminated the need for further dilations prior to antireflux surgery.
Implications:
- Self-expanding esophageal stents demonstrate efficacy in treating pediatric strictures, particularly resolving peptic cases.
- The use of biodegradable stents shows promise for improving outcomes and reducing interventions in pediatric esophageal stricture management.
Objective:
Caustic or peptic esophageal strictures in children are the main cause of multiple dilations, which involve an important anesthetic risk and esophageal trauma. The placement of an esophageal stent can be an advance in the treatment of these patients. The objective of our work is to analiyze the efficacy of self-expanding stents for the treatment of esophageal strictures in children.
Material And Methods:
Three patients with esophageal strictures, one due to caustic and two to peptic esophageal injuries have been treated with esophageal stents. Metal stent covered with nitinol has been used in the first patient, and biodegradable material stent in the rest.
Results:
After a year of serial dilations, we placed two consecutive metal stents in one patient with caustic stricture. After its withdrawal, new dilations have been needed, but with longer asymptomatic period. The other two patients had peptic strictures; biodegradable stents were placed after months of serial dilations, before performing antireflux surgery. None of them needed further dilation.
Conclusions:
Esophageal stent placement has solved the problem without further dilation in peptic esophageal strictures. Asymptomatic period was significantly increased in caustic stricture. The results obtained with self-expanding stents are promising.
