Anatomical description during standard upper endoscopy

In this video (Figure 1), we demonstrate standard upper endoscopy performed on a 50-year-old patient with history of gastroesophageal (GE) reflux disease and dyspepsia. We highlight the common anatomical landmarks of the upper gastrointestinal tract (Table 1, Figure 2) and endoscopic techniques for successful esophageal intubation, gastric retroflexion, duodenal access and tissue sampling using biopsy forceps.
