Core Tip
Core tip: Although accurate photo documentation of endoscopic landmarks and a careful description of the location of an esophageal lesion are included in endoscopy quality guidelines, clinical practice lacks these essentials. This study characterized two esophageal landmarks to permit radial and longitudinal orientation and accurate lesion location. The left main bronchus and left atrium landmarks were identified in 99% and 100% of patients on the anterior esophageal quadrant and at a mean distance of 25.8 cm and 31.4 cm from the incisors, respectively. The endoscopic ultrasound sub-study confirmed these findings and the anterior orientation of the landmarks.
