ICD-11 definition : Gastric ulcer is defined as a distinct breach in the mucosa of the stomach as a result
of caustic effects of acid and pepsin in the lumen. Histologically, gastric ulcer
is identified as necrosis of the mucosa extending through the muscularis mucosae into
the submucosa. In the endoscopic or radiological view, there is an appreciable depth
of the lesion. When the break of epithelial lining is confined to the mucosa without
penetrating through the muscularis mucosae, the superficial lesion is called 'erosion'.;
