Vitamin B12 absorption in patients with continent ileostomy. 1975

R Jagenburg, and N G Kock, and B Philipson

Vitamin B12 absorption was studied in 34 patients, 10 months to 6 years after construction of a continent ileostomy. Normal Schilling test values (greater than 10 percent) were obtained in 21 of the cases after a single determination. Repeated tests showed a normal B12 absorption in 8 of the 13 patients who had revealed a Schilling test value below 10 percent at the first determination. In the remaining 5 patients, repeated Schilling tests showed borderline values (5-10 percent) in 4 cases and a low value (mean 4.5 percent) in one case. One of the patients with borderline values had previously undergone resection of 80 cm of the terminal ileum. When vitamin B12-intrinsic factor complex was instilled directly into the reservoir in 3 patients, it was found that the vitamin was absorbed by the mucous membrane of the reservoir. The construction of a continent ileostomy reservoir thus does not appear to expose the patient to an increased risk of developing vitamin B12 malabsorption.

D007081	Ileostomy	Surgical creation of an external opening into the ILEUM for fecal diversion or drainage. This replacement for the RECTUM is usually created in patients with severe INFLAMMATORY BOWEL DISEASES. Loop (continent) or tube (incontinent) procedures are most often employed.

D011127	Polyps	Discrete abnormal tissue masses that protrude into the lumen of the DIGESTIVE TRACT or the RESPIRATORY TRACT. Polyps can be spheroidal, hemispheroidal, or irregular mound-shaped structures attached to the MUCOUS MEMBRANE of the lumen wall either by a stalk, pedunculus, or by a broad base.	Polyp
D003093	Colitis, Ulcerative	Inflammation of the COLON that is predominantly confined to the MUCOSA. Its major symptoms include DIARRHEA, rectal BLEEDING, the passage of MUCUS, and ABDOMINAL PAIN.

D003424	Crohn Disease	A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental. Epithelioid GRANULOMAS may be seen in some patients.
