Vitamin D level is not a predictor of hypocalcemia after total thyroidectomy.

Article Abstract

Purpose: As the incidence of thyroid cancer has increased, hypocalcemia, a common complication of thyroid surgery, has become a serious problem. However, no definite predictor of postoperative hypocalcemia is known. In this study, our purpose was to investigate the potential role of vitamin D as a predictor of postoperative hypocalcemia.

Methods: A prospective observational study was performed on patients who underwent total thyroidectomy for thyroid cancer performed by a single experienced surgeon between October 2013 and September 2014.

Measurements: Their serum 25-OH vitamin D levels were measured preoperatively. On the day after surgery, serum calcium and intact parathyroid hormone levels were measured, and symptoms of hypocalcemia were recorded.

Results: Of the 134 patients, laboratory and symptomatic hypocalcemia developed in 52 patients (39 %) and 25 patients (19 %), on the day after surgery. The preoperative vitamin D level was 16.5 ± 9.2 ng/mL, and this value did not differ according to laboratory or symptomatic hypocalcemia (p = 0.94). The incidence of laboratory or symptomatic hypocalcemia did not differ according to vitamin D deficiency. Only incidental parathyroidectomy was associated with symptomatic hypocalcemia (p = 0.03).

Conclusions: Vitamin D level is not a predictor of hypocalcemia after total thyroidectomy for thyroid cancer. Thus, routine preoperative screening for vitamin D is not recommended.
