Value of serum inorganic phosphate in the diagnosis of ischemic bowel disease

Abstract

To clarify the value of the serum inorganic phosphate concentration in the diagnosis of ischemic bowel disease, a retrospective study of 24 patients with various causes of intestinal ischemia was carried out. Only 25 percent of the patients had elevations of their serum phosphate concentrations. These patients had the combination of extensive bowel injury, acute renal insufficiency, and acidosis. Mortality was significantly increased in these patients. Thus, the serum phosphate concentration was not a sensitive indicator of ischemic bowel disease, but elevations did predict extensive injury and poor prognosis.
