in the eight patients with two- or three-gland hyperparathyroidism who developed postoperative hypercalcemia , the preoperative concentrations of serum calcium were lower ( 10.8 +/- 0.2 vs. 11.5 +/- 0.2 ; p less than 0.019 ) , the preoperative concentrations of serum phosphate were higher ( 3.1 +/- 0.2 vs. 2.5 +/- 0.1 ; p less than 0.020 ) , and the weights of the excised parathyroid tissues were less ( 356 +/- 72 mg vs. 1354 +/- 215 mg ; p less than 0.02 ) than those of patients with two- or three-gland disease who did not develop postoperative hypercalcemia , indicating a milder form of hyperparathyroidism .
