[Morphology of the liver in peptic ulcer and postgastrectomy complications (electron-microscopic study)]

Electron microscopic examinations of 13 liver biopsies obtained from 4 patients with duodenal ulcer, 4 with peptic ulcer of gastroenteroanastomosis and 3 with the dumping syndrome showed these diseases to be accompanied by nonspecific ultrastructural changes in hepatocytes, intercellular connections, the system of bile tubules and microcirculatory bed which are more marked in postgastroresection complications and not always correspond to the histological condition of the organ, particularly when changes in its histological structure are not very marked. From the fact that the range of ultrastructural changes in the livers of patients of these groups are more extensive and variable than histological ones, it may be assumed that the intact histostructure of the organ does not exclude the occurrence of pathological processes in it.
