Reviewer's report:
Dear Authors, 
My comments about this manuscript are: 
1.- The main point of this manuscript wants to show a minimally invasive
technique to resect a benign esophageal tumor, so It´s very important to describe
very clear , step by step all the surgical technique and add more photos about the
surgery. You put more photos about CT-Scan and you should use only one photo
with ct-scan and endoscopic ultrasound. 
2.- It would be interesting to know how many centimeters you opened muscular
layer to resect tumor, was It only around hiatus ?? or intrathoracic ?? near of
carina???
3.- You must check the english redaction and orthography
