Primary hyperparathyroidism (PHPT) is one of the most frequent endocrine diseases worldwide. Surgery is the only potentially curable option for patients with this disorder, even though in asymptomatic patients 50 years of age or older without end organ complications, a conservative treatment may be a possible alternative. Bilateral neck exploration under general anaesthesia has been the standard for the definitive treatment. However, significant improvements in preoperative imaging, together with the implementation of rapid parathyroid hormone determination, have determined an increased implementation of focused, minimally invasive surgical approach. Surgeons prefer to have a localization study before an operation (both in the classical scenario and in the minimally invasive procedure). They are not satisfied by having been referred a patient with just a biochemical diagnosis of PHPT. Imaging studies must not be utilized to make the diagnosis of PHPT. They should be obtained to both assist in determining disease etiology and to guide operative procedures together with the nuclear medicine doctor and, most importantly, with the surgeon. On the contrary, apart from minimally invasive procedures in which localization procedures are an obligate choice, some surgeons believe that literature on parathyroidectomy over the past two decades reveals a bias towards localization. Therefore, surgical expertise is more important than the search for abnormal parathyroid glands.

Objectives 1) Delineate the role of CT-technetium 99m sestamibi (CT-MIBI) fusion in directed parathyroidectomy. 2) Determine the clinical situations where CT-MIBI fusion would be strongly recommended. Methods Charts from 190 patients with primary hyperparathyroidism who underwent CT-MIBI mage fusion as a part of a scan directed, minimally invasive parathyroid exploration protocol were reviewed. The results of conventional sestamibi imaging and CT-MIBI image fusion were compared with operative findings. Results CT-MIBI image fusion accurately localized solitary hyperfunctional parathyroid glands in 70% of patients imaged; 55% of patients were localized with conventional sestamibi imaging. CT-MIBI fusion imaging was most accurate and predictive when conventional images suggested that the solitary gland was separated from the thyroid or when the adenoma was located in the retro-thyroidal/ retro-esophageal plane or mediastinum. Conclusions CT-MIBI image fusion is not superior to conventional sestamibi imaging when utilized for routine localization of hyperfunctional parathyroid glands. CT-MIBI fusion is of greatest benefit in guiding the directed approach to solitary glands, which are separate from the thyroid or ectopically located, regions where conventional imaging has proven to be less accurate. This imaging technique will augment the minimally invasive surgical approach in selected patients with primary hyperparathyroidism in order to further refine the focused technique. Its utility as the standard preoperative localization modality is not yet established and requires further investigation. Evaluation of differences in facility utilization with CT-MIBI image fusion and conventional sestamibi imaging may be helpful in determining its role in preoperative localization for hyperparathyroidism.

AbstractBackgroundPrimary hyperparathyroidism is the third most common endocrine disorder for which surgical procedure called parathyroidectomy is the most effective treatment. Since the early 20th century, parathyroid surgery has improved extensively. With the advances in preoperative imaging and with understanding the causes of disease, new and minimally invasive surgical approaches overrode the standard bilateral exploratory operations. Directed parathyroidectomy is currently the standard technique for treatment of primary hyperparathyroidism worldwide.ConclusionsSurgery is the only definitive treatment of primary hyperparathyroidism. The most appropriate type of surgical procedure depends on the number and localization of the hyperactive parathyroid glands, availability of modern imaging techniques, limitation of each type of procedure and expertise.

The parathyroid glands, one of the last organs to be discovered, are responsible for maintaining calcium homeostasis, and they continue to present the clinician with diagnostic and management challenges that are reviewed herein. Primary hyperparathyroidism (PHPT) comprises the vast majority of pathology of the parathyroid glands. The classic variant, presenting with elevated calcium and parathyroid hormone levels, has been studied extensively, but the current body of literature has added to our understanding of normocalcemic and normohormonal variants of PHPT, as well as syndromic forms of PHPT. All variants can lead to bone loss, kidney stones, declining renal function, and a variety of neurocognitive, gastrointestinal, and musculoskeletal complaints, although the majority of PHPT today is asymptomatic. Surgery remains the definitive treatment for PHPT, and advances in screening, evolving indications for surgery, new imaging modalities, and improvements in intra-operative methods have greatly changed the landscape. Surgery continues to produce excellent results in the hands of an experienced parathyroid surgeon. For those patients who are not candidates for surgery, therapeutic advances in medical management allow for improved control of the hypercalcemic state. Parathyroid cancer is extremely rare; the diagnosis is often made intra-operatively or on final pathology, and recurrence is common. The mainstay of treatment is normalization of serum calcium via surgery and medical adjuncts.

Introduction. Elderly patients with primary hyperparathyroidism (pHPT) are often not referred to surgery because of their associated comorbidities that may increase surgical risk. The aim of the study was to review indications and results of minimally invasive approach parathyroidectomy in elderly patients to evaluate its impact on outcome.Materials and Methods. All patients of 70 years of age or older undergoing minimally approach parathyroidectomy at our Department from May 2005 to May 2011 were reviewed. Data collected included patients demographic information, biochemical pathology, time elapsed from pHPT diagnosis to surgical intervention, operative findings, complications, and results of postoperative biochemical studies.Results and Discussion. 37 patients were analysed. The average length of stay was 2.8 days. 11 patients were discharged within 24 hours after their operation. Morbidity included 6 transient symptomatic postoperative hypocalcemias while one patient developed a transient laryngeal nerve palsy. Time elapsed from pHPT diagnosis to first surgical visit evidences that the elderly patients were referred after their disease had progressed.Conclusions. Our data show that minimally invasive approach to parathyroid surgery seems to be safe and curative also in elderly patients with few associated risks because of combination of modern preoperative imaging, advances in surgical technique, and advances in anesthesia care.

Primary hyperparathyroidism (PHPT) is a common endocrine disease that occurs with multiple profiles in which no classical manifestation. Diagnosis revolves around routine measurement of serum calcium and parathyroid hormone more than in half cases. The understanding of clinical presentation, epidemiology and management tactics of patients with hyperparathyroidism has significantly changed by virtue of the use of biochemical calcium screening. The successful diagnosis and treatment are possible with the cooperation of a multidisciplinary team of endocrinologist, endocrine surgeon, radiologist, nuclear medicine physician and pathomorphologist. The only radical method of treatment is the surgical removal of abnormal parathyroid glands. In this regard, there is necessary to improve the parathyroid glands imaging algorithms. Early treatment of hyperparathyroidism allows to avoid severe damage to the bones, kidneys, heart, other organs, improving the quality of life and reducing the incidence of disability. For a systematic literature review, more than 100 articles published from 2000 to the present time were used, on following resources: PubMed, Embase, SciSearch, Scopus, Cochrane Databases, Research Gate, Google Scholar. Including recommendations from the American Association of Endocrinologists and Endocrine Surgeons (AACE/AAES), European Society of Nuclear Medicine (EANM), European Society ofEndocrinologists (ESE), Russian Association of Endocrinologists (RAE) and several other organizations. The main goal of this review is to summarize and present relevant information and a new look on preoperative imaging techniques, methods of intraoperative navigation, surgery, control quality of treatment in patients with primary hyperparathyroidism.

Purpose The aim of this study was to evaluate the accuracy of multidetector computed tomography (MDCT) in the detection of parathyroid adenoma and hyperplasia in the setting of primary hyperparathyroidism. Methods Records of 48 patients with biochemically confirmed primary hyperparathyroidism, who underwent preoperative imaging with 16- or 64-slice contrast-enhanced MDCT and subsequent successful parathyroidectomy over a 3-year period, were reviewed. Two radiologists, blinded to the operative and histologic findings, independently evaluated multiplanar computed tomographic images for all patients. Results On pathologic examination, 63 abnormal glands were confirmed in 41 female and 7 male patients (mean age, 63 years). Of the 63 abnormal glands, 40 were adenomatous and 23 were hyperplastic. MDCT demonstrated an 88% (95% confidence interval [CI], 77%–99%) positive predictive value for localizing abnormal hyperfunctioning parathyroid glands. The sensitivity of MDCT in detecting single-gland disease was 80% (95% CI, 68%–92%); whereas the specificity for ruling out hyperfunctioning parathyroid tissue, either adenomatous or hyperplastic, was 75% (95% CI, 51%–99%). The sensitivity for exclusively localizing parathyroid hyperplasia was 17% (95% CI, 2%–33%). The parathyroid adenomas were substantially larger and heavier than their hyperplastic counterparts, with an average weight of 1.51 g (range, 0.08–6.00 g) and 0.42 g (range, 0.02–2.0 g) for adenoma and hyperplasia, respectively. Conclusions Contrast-enhanced MDCT demonstrated an 88% positive predictive value for localizing adenomatous and hyperplastic parathyroid glands. The poor sensitivity for detection of multigland disease was likely a result of the smaller size and weight of the abnormal hyperplastic glands.

Object Lumbar synovial cysts are a potential cause of radiculopathy and back pain, and the definitive treatment is the complete excision of the cyst. This report summarizes the authors' preliminary clinical experience with the minimally invasive resection of lumbar synovial cysts. Methods Nineteen patients (nine men and 10 women) with symptomatic synovial cysts underwent minimally invasive resection. The mean patient age was 64 years of age (range 43–80 years). The presenting symptom was radiculopathy in 16 patients, low-back pain in two, and lower-extremity weakness in one. There were 16 cases of a cyst located at the L4–5 level, two at L3–4, and one at L5–S1. The mean cyst diameter was 13.7 mm (range 3–30 mm). The mean follow-up time was 16 months (range 4–29 months). Clinical outcomes were graded, based on the Macnab modified criteria, as excellent, good, fair, or poor. Eighteen patients (95% of cases) reported either excellent (10 patients) or good (eight patients) results, and a fair result was reported by one patient (5% of cases). The mean operative time was 158 minutes (range 75–270 minutes), and the average intraoperative blood loss was 31 ml (range 10–100 ml). Two patients had intraoperative dural tears that resulted in cerebrospinal fluid leaks that resolved following primary closure. Conclusions Synovial cysts can be safely and effectively treated using minimally invasive surgical techniques. Long-term follow up is required to determine whether this approach results in less need for fusion than conventional surgical approaches.
