I think her incision looks very tidy -- maybe the 33 cents was for double-knotting the stitches?
But, um, food doesn't go down the trachea (windpipe) -- unless they're aspirating. Trachea is the ringed tube in the front of the neck going down to lungs. Esophagus is just posterior to the trachea, going down to the stomach. There are various procedures the body performs automatically during a normal swallow to prevent food from going down the trachea. Sometimes surgery in this area may create problems swallowing depending on what muscles get moved around/cut, but fortunately it doesn't sound like this is a problem for your girl.
