We have performed the procedure described by Prof. Mutaf in persistent esophageal strictures in children. The stent formed by teflon was held in the stricture line for about one year. The results were quite successful.
Dear Dr Sira, the details of the study were presented in the article entitled as "Mutaf O. Treatment of corrosive esophageal strictures by long-term stenting. J Pediatr Surg. 1996 May;31(5):681-5."
Yes, we have a well-established protocol for non-operative management in pediatric esophageal trauma. You can have a look at our protocol here:
