  so very sorry that you are going thru this.  They are quick and get into many things so don't blame yourself.  My first response would be, do you feel comfortable with your current vet?  Or do you feel a second opinion would put your mind at more ease?  
 I think that I would go with the endoscopy since it would be less invasive. Best of luck for what you decide. hugs.
