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.
