The AFS announces a new endoscopic classification of the esophagogastric junction. The classification recognizes that the antireflux barrier involves the crural diaphragm and intrinsic lower esophageal sphincter in addition to the flap valve classification as described by Hill. It stratifies EGJ integrity from normal (grade 1) to increasing degrees of EGJ disruption (grade 2-4) beginning with loss of the flap valve and progressing to increasing degrees of crural disruption and hiatus hernia. It also stipulates appropriate endoscopic methodology for the assessment and provides a basic nomenclature for communication among endoscopists.
