| [ Summary ] | Reflux esophagitis is divided endoscopically into four grades', A to D, according to the severity of mucosal breaks [Los Angeles (LA) classification]. A mucosal break was defined as ´an area of slough or an area of erythema, with a discrete lined demarcation from the adjacent or normal looking mucosa´. Dr. Hoshihara proposed a modification of the LA classification, including a classification for minimal changes being grade M and for an esophagus with only minimal changes and/or mucosal breaks being grade N. In Japan, this modified classification is mainly used at present. | |
