Small bowel intussusception and brown bowel syndrome in association with severe malnutrition.

Brown bowel syndrome is a rare condition characterized by deposition of lipofuscin in the smooth muscle cells of the gastrointestinal tract. The number of reported cases is small, but all are associated with malabsorptive states. Despite these small numbers, there is considerable evidence that vitamin E deficiency is important etiologically. We report here the case of a severely malnourished [body mass index 11.7 kg/m (2): normal range 20-25 kg/m (2)] 31-yr-old black male with a longstanding history of alcohol abuse, who was on anti-tuberculosis therapy. The patient presented with an acute abdomen and was found, at operation, to have a mid-ileal intussusception. Histological examination of the resected specimen demonstrated lipofuscin accumulation consistent with brown bowel syndrome, but no tumor. Subsequent investigations revealed no significant quantities of vitamin E in the blood and pancreatic steatorrhea. However, deficiency of other fat-soluble (vitamin A and D) and water-soluble vitamins (vitamin C and thiamine) also were detected. This report supports the association of brown bowel syndrome with vitamin E deficiency but cannot exclude the compounding effects of protein calorie malnutrition, multiple vitamin deficiencies, and chronic alcohol toxicity.
