Under a Postgastrektomiegastritis is meant a gastric atrophy, which develops after a partial or subtotal gastrectomy (except in the case of gastrinomas).
Metaplasia of the remaining corpus mucosa usually occurs. The degree of gastritis is most pronounced in general on the Anastomosengrenze.
Under a Postgastrektomiegastritis is meant a gastric atrophy, which develops after a partial or subtotal gastrectomy (except in the case of gastrinomas). Metaplasia of the remaining corpus mucosa usually occurs. The degree of gastritis is most pronounced in general on the Anastomosengrenze. Several mechanisms are responsible: a bile reflux, which often occurs after such an operation, damages the stomach lining. By a loss of antralem gastrin dieStimulation is reduced from parietal and peptic cells, which leads to atrophy. A vagotomy can lead to a loss of vagal trophic effect. There are no specific symptoms of gastritis. The Postgastrektomiegastritis often developed a severe atrophy and achlorhydria. The production of intrinsic factor is set and the result is a vitamin B12 deficiency (which is exacerbated by bacterial overgrowth in the afferent loop). The relative risk for the development of adenocarcinoma of the stomach seems to increase after partial gastrectomy 15-20 years; However, given the low absolute incidence of Postgastrektomiekarzinoms a routine endoscopic surveillance is unlikely to be cost effective and only corresponding symptoms in the upper GIT or anemia should lead to a rapid endoscopic investigation in affected patients.
