Endoscopic management for congenital pyriform sinus fistula

We read the article "KTP laser assisted endoscopic tissue fibrin glue biocauterization for congenital pyriform sinus fistula in children" by Huang et al. [1] with great interest. The study presents a novel surgical management that is considered to be less invasive, safe, and effective. The innovation spirit is highly commendable and we appreciate their contribution to the treatment of pyriform sinus fistula. Yet we think one point is in doubt.
