| Summary: | Background: Hungry bone syndrome is a common complication of surgery for primary hyperparathyroidism in India which often leads to prolonged hospitalization. There are varying reports on the use and efficacy of bisphosphonates in the prevention of hungry bone syndrome. Methods: We retrospectively analyzed the effect of preoperative bisphosphonate therapy on rates of hungry bone syndrome in our patients with primary hyperparathyroidism. A total of 19 patients underwent surgery for primary hyperparathyroidism at our institute between January 2013 and June 2015 among whom eight did not receive preoperative bisphosphonates and 11 received intravenous zoledronic acid 4 mg, 24–48 h preoperatively. Results: There was no significant difference between the two groups with respect to age, gender, duration of symptoms, preoperative serum calcium, phosphorus, parathyroid hormone, alkaline phosphatase, and the presence of radiological evidence of hyperparathyroid bone disease also did not differ between the groups. Three out of the eight patients who did not receive preoperative zoledronic acid therapy had hungry bone syndrome but none in the zoledronic acid group. The prevalence of hungry bone syndrome tended to be lower in the zoledronic acid group (P = 0.058). The need for intravenous calcium and duration of postoperative hospital stay were significantly lesser in the zoledronic acid group. Conclusion: Preoperative intravenous zoledronic acid significantly reduces the need for intravenous calcium therapy and duration of postoperative hospital stay and seems a promising option to reduce the rate of hungry bone syndrome in patients with primary hyperparathyroidism.
