The distributions in the stomach of gastric atrophy and intestinal metaplasia frequently vary. For this reason a minimum of four biopsies from two different topographic areas is suggested. Ideally they should be taken from the greater curvature and lesser curvature of the antrum and gastric body. In addition biopsies should be taken from suspicious areas.
La atrofia gástrica y la metaplasia intestinal tienen frecuentemente distribución variable en el estómago, es por esta razón que se sugiere como mínimo la toma de 4 biopsias de 2 sitios topográficos diferentes idealmente curvatura mayor y curvatura menor del antro y cuerpo gástrico y adicionalmente biopsias de sitios sospechosos.
