short bowel syndrome

Inadequate absorption of ingested nutrients (esp. vitamin B12, macronutrients, sodium, and magnesium) resulting from a surgical procedure in which a considerable length of the intestinal tract has been removed or bypassed. Patients with short bowel syndrome may experience anion gap metabolic acidosis caused by the accumulation of the D-isomer of lactic acid in serum. Aggressive enteral nutrition or creation of an antiperistaltic segment in the remaining intestine may replace the need for partial or total parenteral nutrition in the management of this syndrome. Transplantation of the small intestine would be ideal, but it has had limited application. SEE: total parenteral nutrition.
