What can i expect from an endoscopy with esophagus stretching?

Easy test!: Once sedated, a tv camera on a thin, flexible tube is inserted by mouth, & is passed gently into your esophagus, stomach, & upper part of the small intestine. Depending on the reason for the exam, biopsies may be taken for H.pylori bacteria, celiac sprue, eosinophilic esophagitis, barrett's esophagus, polyps can be removed, bleeding can be controlled, & dilation performed (by balloon or bougie).
