title: [Histopathological, electron microscopic and microbiological studies in patients with obstructive large-bowel ileus of tumor origin].
abstract: We have studied the Liver and colon of 23 patients histologically, and 15-electron microscopically. In the course of light microscopic observation of the colon wall above the obstruction we found: degeneration and desquamation of epithelial lining, decrease of goblet cells, increase of acid glycoproteins, hypertrophy of myofibrils in the muscle layer and fibrogenesis in the interstitial tissue in between. In liver: there was slight to moderate fibrosis in portal tracts and somewhere in the sinusoids, and moderate inflammatory infiltrate in them. Electron microscopic observations showed: a. in colon above the carcinomatous obstruction we found hypertrophy of muscle cells and in between collagenoblasts I-II type; b. in liver without metastases the space of Disse was distended, with bundles of collagen somewhere. Ito cells showed signs of fibroblast transformation. Our hypothesis is that these chronic changes are a reaction to the protracted obstruction and to colon carcinoma.
