Abortion studies in patients with "intraabdominal ileostomy reservoirs" and in patients with conventional ileostomies.

Twenty patients with ileostomy were studied concerning the absorption of d-xylose, fat, l-phenylalanine, and vitamin B(12). Ten patients had a conventional ileostomy, whereas 10 others were provided with an intraabdominal intestinal ileostomy reservoir resulting in faecal continence. No remarkable differences in the absorption of d-xylose, fat, or l-phenylalanine were found between the two groups of ileostomy patients. Most of the absorption values were within normal or borderline ranges. In the reservoir group the Schilling test gave subnormal values in six out of 10 patients, whereas only one patient in the group with a conventional ileostomy had a subnormal value. The reason for this finding is briefly discussed.
