The purpose of this study is to conduct a randomized clinical trial to compare the incidence
of dysphagia in patients receiving general anesthesia with and without an endotracheal tube
for Upper gastrointestinal endoscopy. If the incidence of dysphagia is found to be increased
following endotracheal intubation for this procedure it could influence the investigators
practice as anesthesiologists and may mandate the future routine use of laryngeal tracheal
application of lidocaine at the time of intubation for example.
