Detection of normal and pathologic parathyroid glands often is difficult due to their variability in number and location. We have implemented photosensitizer-induced fluorescence for the routine intraoperative identification of parathyroids for the surgical treatment of hyperparathyroidism. From 2004 to 2007, 25 patients suffering from primary and secondary hyperparathyroidism underwent minimally invasive videoscopic-assisted parathyroidectomy after oral photosensitization with aminolevulinic acid (ALA). Fluorescence was sufficiently strong in 48% of patients to aid faster detection of the glands in situ. In an additional 44%, the fluorescence behavior supported the identification of the glands in situ and after excision, yielding a total of 92% of glands whose identity could be confirmed by the fluorescence technique. Fluorescence-guided minimally invasive parathyroidectomy is technically feasible and may support the surgeon in detecting and confirming the parathyroid glands. As the fluorescence method requires only moderate additional technical efforts and clinical expenditure, it is a valuable add-on component in parathyroid surgery to facilitate the operation.

    In uremic patients, metabolism of 1-84 parathyroid hormone (PTH) and fragments are delayed, and in these patients, the usefulness of intraoperative PTH assay may be problematic. We evaluated the usefulness of the QuiCk-IntraOperative Bio-Intact PTH (QPTH) assay for uremic patients with secondary...

    Background: Parathyroid carcinoma accounts for <1% of tumors in primary hyperparathyroidism (PHPT). Distinguishing parathyroid malignancy from benign disease is difficult both before and after initial surgery. Despite the improved specificity of a malignant diagnosis with immunohistochemistry...

    Background: Parathyroid cysts (PCs) are rare, and their origin is a subject of debate. They have been described as either functional, causing hyperparathyroidism, or non-functional in eucalcaemic patients. Patients and methods: We have performed a 25-year departmental review of PCs. Features...

    Elevation of parathyroid hormone (PTH) levels is commonly seen in patients with primary hyperparathyroidism (PHPT) who have undergone parathyroidectomy. This study evaluates differences in 2-week postoperative PTH levels in patients having focused-approach surgery versus four-gland exploration....

    An encyclopedia entry for "parathyroidectomy" is presented. It describes the term as surgical removal of one or more of the parathyroid glands. The procedure is done to treat hyperparathyroidism or neoplasm. According to the article, hypocalcemia may be produced after the removal of the...

    Background. Successful kidney transplantation is believed to cure secondary hyperparathyroidism, but persistent disease has emerged in a significant number of allograft recipients. A parathyroidectomy is ultimately required in some of these patients. To gain insight into the incidence, risk...

    Background. The increase of bone mineral density in cortical bone after parathyroidectomy is smaller than that in cancellous bone. Changes of serum bone markers reflect those of bone metabolism both in cortical and cancellous bone after parathyroidectomy. The present study was undertaken to...
