  • Abstract
  • Look Inside

 From July 1971 to December 1987, 231 cases of acute gastric mucosal lesions (AGML) diagnosed definitively by endoscopy were examined at Kitasato University Hospital. The main inducing factors of AGML were drugs (87 cases), emotional stress (57 cases) and unknown (51 cases). Physical stress causing AGML included surgical operation in nine patients, burn in three and trauma in two. On pathogenesis of AGML, there are many reports indicating defensive factors (mucosal blood flow, mucus production, etc) play more important role than aggressive factors (gastric acid and pepsin secretion). However, with respect to surgery-related stress ulcer caused by vagal stimulation, sympathetic stimulation and adrenocortical hypersecretion, it is considered essential that the balance between aggressive factors and defensive factors is disturbed.
