Title: 
Repair of a Three-way Congenital Bronchoesophageal Fistula in an Adult
Patient:a Case Report
Version: 
0 
Date: 
19 Sep 2021
Reviewer's report:
The authors presented an extremely rare case of an adult with three-way
congenital bronchoesophageal fistula which was successfully repaired by a
double-layer repair of the airway fistula by using esophageal wall tissues as
patch materials. The writing is well-constructed, and the information is
educational. There are some questions and suggestions for the authors:
Q1. Would you please add arrows for highlighting the opening fistula and
closured fistula on Fig. 1 and Fig. 3 respectively?
Q2. Why does Fig. 3 (d) figure look like some necrotic tissue overlying the
fistula?
Q3. Can you put some surgical pictures along with the Fig. 2 for better
explanation of the procedures?
