[Changes in stomach mucosa in swine: a literature review].

Oesophagogastric lesions are a worldwide problem in swine. After extensive research in the 1960s, with primarily indications for a relationship with nutrition, no new reports were published for a long time. Recently, oesophagogastric lesions in swine have come to the centre of attention again, because there are indications for an increase in the prevalence of oesophagogastric lesions, and in particular ulcers, in swine. Therefore recent advances in the field are reviewed. The pathogenesis, prevalence, risk factors and economic consequences of oesophagogastric lesions are discussed.
