[Classification of peptic ulcer]

To make more simple and useful classification of peptic ulcer the following criteria of the above classification are proposed: nosological entity (ulcer), form (primary, recurrent), site (subcardial, mediogastric, antral, pyloric. duodenal bulbar and duodenal retrobulbar), activity (A-III--a severe exacerbation, A-II--a moderate exacerbation, A-I--clinical remission, A-0--complete remission), clinical course (severe, moderate, light, latent), complications (perforation, hemorrhage, penetration, malignant transformation, pyloric stenosis compensated, pyloric stenosis decompensated).
