[Fat absorption in patients with inflammatory diseases of the large intestine and diffuse polyposis].

Radioisotope method with oral administration of 131I-trioleate glycerin and 131I-oleic acid was used to study the absorption of neutral fats and fatty acids in 123 patients with ulcerative colitis, diffuse polyposis of the large intestine, and in 7 patients with ileostomy. It was found that fat secretion with feces was insignificantly higher than the normal and fluctuated within the range of 6.6-11.7%. Steatorrhea did not play a role in the development of clinical symptoms of the disease, and it might be caused by concomitant disorders in the bacterial flora. Slight disorders revealed in the fat absorption should not be considered as an obstacle to their normal use in the diet.
