Primary hyperparathyroidism: a case study.

Abstract

Primary hyperparathyroidism is a hypercalcemic condition generated as a result of overproduction of parathyroid hormone (PTH) by one or more of the parathyroid glands. The cause is usually an abnormal group of cells forming a benign adenoma and rarely carcinoma. The condition is usually discovered by routine serum chemistry analysis showing hypercalcemia, hypophosphatemia, and elevated PTH levels. Elevated 24-hour urine calcium provides further confirmation. During the last decade, three procedures have been developed to help diagnose the affected parathyroid gland(s) in preparation for surgical intervention: computerized nuclear scanning with technetium-99-m sestamibi performed preoperatively; radio-guided probes; and rapid PTH assay (RPHA), both used intraoperatively. These three techniques have been reported to reduce the need for immediate frozen section diagnosis; shorten the length of the incision, surgical time, and length of hospital stay; produce less pain and discomfort; reduce surgical cost; and produce a quicker return to normal life. This article follows the surgical experience of a patient with a diagnosis of hyperparathyroidism and a history of postoperative nausea and vomiting who was scheduled as 23-hour stay.
