Pathological and pathophysiological study on intestinal lymphatic system in fat absorption.

Pathological and pathophysiological study on the intestinal lymphatics was carried out clinically and experimentally. Jejunal biopsy study revealed marked dilatation of intestinal lymphatics in liver cirrhosis with ascites and Behçet's disease as well as protein-losing enteropathy. Lymphangiographic study showed also abnormal findings in above-mentioned diseases. In cases of McKee dogs in which mechanism of blockade of lymphatic flow was already clarified, McKee dogs showed marked malabsorptive of fat. When lymphatic flow was blocked mechanically at the thoracic duct, fat accumulation was seen in the absorptive cells as well as in dilated intestinal lymphatics. In administration of colchicine to rats, fat accumulation was seen in the matrix of absorptive cells as well as in the endoplasmic reticulums and Golgi apparatus. However, amorphous substances instead of chylomicrons were seen in dilated intestinal lymphatics. These studies suggested that a tract of fat transportation from intestinal cells to the thoracic duct should be considered as a functional unit in fat absorption.

[Diagnostic and therapeutic problems posed by 2 cases of exudative enteropathy].

The authors report two cases of exsudative enteropathy characterised by the existence of oedema of the lower limbs associated with hypoproteinemia and marked lymphopenia with disturbances of the P.V.P. test. In both cases lymphography demonstrated major abnormalities with obvious obstruction in one case, and signs of slowing of lymph flow with appearances of dysplasia in the other. Surgery permitted us in one case, to discover a calcified lymph node probably due to tuberculosis. The etiology of these cases is discussed and seems to be mainly related to abnormalities of the lymphatic system. A low fat diet and administration of medium-chain triglycerides, gave an undoubted improvement when the treatment was followed by the patient. These two cases illustrate well the difficult diagnostic and therapeutic problems sometimes raised by syndromes of exsudative enteropathy, in particular owing to the many possible causes.
