Abstract
In order to obtain more information about the excretion of fat by the intestine of man. observations were made on 14 human beings. Excretion of fat by normal persons was greater than excretion of fat by patients who had been subjected to resection of the right portion of the colon. Furthermore, excretion of fat by patients who had thrombo-ulcerative colitis was less than excretion of fat by normal persons, but was greater than excretion of fat by the patients who had been subjected to resection of the right half of the colon. The amt. of fat in the feces of the subjects who received a fat-free diet varied, but an avg. of 0.79% of total fat was excreted by persons who had been subjected to an ileostomy or an ileocolostomy. an avg. of 0.81% was excreted by persons who had thrombo-ulcerative colitis and an avg. of 1.23% was excreted by normal persons; however, the deviation from the averages is considerable. These facts would suggest that the large intestine itself plays a part in the excretion of fat, and that the greatest excretion occurs in the proximal segments of the large intestine.
