Abstract
To study post-gastrectomy metabolic bone disorders, we measured the radial bone mineral content (BMC), serum levels of calcium, inorganic phosphorus, alkaline phosphatase, and 25-hydroxyvitamin D(25-OH-D) in 59 patients with partial- and 39 patients with total gastrectomy. Total gastrectomy patients manifested a higher incidence of decreased BMC levels than did partial gastrectomy patients (56 per centvs. 25 per cent). Patients subjected to the Billroth II procedure, especially females, manifested abnormally low BMC values. The decline in BMC was age-related; it was pronounced in females. At 10 years postoperatively, many of the partial gastrectomy patients manifested markedly low BMC levels; in totally gastrectomized patients this finding was made at less than 5 years postoperatively. Approximately 30 per cent of our patients showed abnormalities in serum minerals, alkaline phosphatase or 25-OH-D.
