Purpose
Esophageal strictures refractory to conservative treatment represent a major problem in chil-dren.
Recently, the application of mitomycin C to the lesion of strictures has been introduced.
We investigated our clinical experience with this procedure in refractory esophageal stricture.
Methods
From September 2011 to September 2013
16 patients: 15 esophageal stricture after the surgery of
esophageal atresia
1 corrosive esophageal injury due to lithium bat-tery ingestion after esophagectomy
Mitomycin C balloon dilatation Drug eluting microporous PTFE balloon catheter
after pre-balloon dilatation under the general anesthesia by intervention radiologist
Methods
Pre- Pre-bal-loon
Mitomycin C After-
