Abstract
The occurrence of postgastrectomy bone disease was studied in 42 patients who had been subjected to gastric surgery for duodenal or gastric ulceration 5-7 years earlier. Hypocalcemia, hypophosphatemia, and an increase in serum alkaline phosphatase were infrequent. No difference was observed in S-25OHD between the patients and controls, but S-24,25(OH)2D was higher in the patients. The bone mineral density (BMD) values showed no statistically significant difference between the patients and controls before or after the operation. There was a slight fall in BMD values during the follow-up period, but the decrease was similar in the patients and controls and was not statistically significant. The histomorphometric analysis revealed a greater amount of trabecular bone and osteoid in the patients. The means of the osteoid variables were well within normal limits, but a very slight increase in osteoid volume was observed in 4 of the 35 patients. It is concluded that a partial gastrectomy and vagotomy had not caused significant disturbances in bone mineral metabolism. The vitamin D status of the patients was good owing to the adequate dietary regimens that had been given to the patients.
