Title: 
Endoscopic recanalization for the complete closure of long-gap
esophageal atresia after reconstruction surgery

Reviewer's report:
This is an interesting case reporting on endoscopic recanalization after complete
closure of esophageal lumen following correction of type A esophageal atresia.
Although of interest, the treatment proposed seems to be not reasonable since the
authors reported "repeated balloon dilations under fluoroscopy performed due to
suture leakage and subsequent stricture". This endoscopic ballooning of
esophageal stenosis was performed before the detection of complete esophageal
closure. Therefore, we may argue the unsuccessful endoscopic management of
esophageal stenosis, with persistent refractory stenosis. In those cases, surgery is
advisable to solve the problem, performing a new anastomosis (either with
native esophagus or with substitutes). The proposed endoscopic recanalization,
although technically feasible, has poor logic consistency since it reproposed an
already failed treatment, postponing a resolution of esophageal problem. The
main question in my opinion is: Why a new endoscopic treatment should be
more effective than similar ballooning already performed (and failed)?
