Endoscopic Evaluation of the Esophagus and Endoscopic Ultrasonography of the Esophagus

Abstract In this chapter the fundamentals of esophagogastroduodenoscopy (EGD) will be explained with an emphasis on the assessment of patients with gastroesophageal reflux disease (GERD). It includes the fundamentals of endoscopic ultrasound (EUS) in the assessment of esophageal cancer. Numerous color photographs demonstrate different findings of interest on EGD through the spectrum of GERD, from erosive esophagitis to cancer. Photographs of EUS images will help demonstrate findings of interest in cancer patients.
