  • Inadvertent Parathyroidectomy During Thyroid Surgery for Papillary Thyroid Carcinoma and Postoperative Hypocalcemia
    ORIGINAL J Korean Thyroid Assoc ARTICLE Vol. 5, No. 1, May 2012 Inadvertent Parathyroidectomy during Thyroid Surgery for Papillary Thyroid Carcinoma and Postoperative Hypocalcemia Dongbin Ahn, MD1, Jin Ho Sohn, MD, PhD1, Jae Hyug Kim, MD1, Ji Young Park, MD2 and Junesik Park, MD, PhD3 Departments of Otolaryngology-Head and Neck Surgery1, Pathology2, School of Medicine, Kyungpook National University, Department of Otolaryngology-Head and Neck Surgery, School of Medicine, Catholic University of Daegu3, Daegu, Korea Background and Objectives: The aim of this article is to report our experience of inadvertent parathyroidectomy during thyroid surgery and to analyze its associated factors and clinical implications. In addition, we attempted to determined causative factors that result in permanent hypocalcemia after thyroid surgery. Materials and Methods: We performed a retrospective review of 500 patients who underwent thyroid surgery for the treatment of papillary thyroid carcinoma from 2004 to 2008. Results: Inadvertent parathyroidectomy was identified in 7.4% of patients and only 1 parathyroid gland was inadvertently removed in most cases. The incidence of inadvertent parathyroidectomy was not associated with gender, age, type of surgical procedure, tumor size, coexisting Hashimoto’s thyroiditis (HT), extra-thyroidal extension (ETE), lymph node (LN) metastasis, and surgeon’s experience. Nor was inadvertent parathyroidectomy associated with permanent postoperative hypocalcemia. Although operating time >120 min, ETE, and total thyroidectomy (TT) with central neck dissection (CND) were found to be related to permanent hypocalcemia on univariate analysis, tumor size ≥1 cm and surgeon’s experience ≤5 years was statistically associated with permanent hypocalcemia on both univariate and multivariate analyses. Conclusion: Although inadvertent parathyroidectomy is not an uncommon complication of thyroid surgery, it appears to have only modest clinical implications.

  • Postoperative Calcium Requirements in 6000 Patients Undergoing
    Postoperative Calcium Requirements in 6,000 Patients Undergoing Outpatient Parathyroidectomy: Easily Avoiding Symptomatic Hypocalcemia Marie Vasher, MD, Arnold Goodman, MD, FACS, Douglas Politz, MD, FACS, FACE, James Norman, MD, FACS, FACE BACKGROUND: To determine the amount and duration of supplemental oral calcium for patients with varying clinical presentations discharged immediately after surgery for primary hyperparathyroidism. STUDY DESIGN: A 4-year, prospective, single-institution study of 6,000 patients undergoing parathyroidectomy for primary hyperparathyroidism and discharged within 2.5 hours. Based on our previous studies, patients are started on a sliding scale of oral calcium determined by a number of preoperative measures (ie, serum calcium, body weight, osteoporosis) beginning 3 hours post- operation and decreasing to a maintenance dose by week 3. Patients reported all hypocalcemia symptoms daily for 2 weeks. RESULTS: Seven parameters were found to have a substantial impact on the amount of calcium required to prevent symptomatic hypocalcemia: preoperative serum calcium Ͼ12 mg/dL, Ͼ13 mg/dL, and Ͼ13.5 mg/dL, bone density T score less than Ϫ3, morbid obesity, removal of Ͼ1 parathyroid, and manipulation/biopsy of all remaining glands (all p Ͻ 0.05). Each independent variable increased the daily calcium required by 315 mg/day. Using our scaled protocol, Ͻ8% of patients showed symptoms of hypocalcemia, nearly all of whom were successfully self-treated with additional oral calcium. Only 6 patients (0.1%) required a visit to the emergency room for IV calcium, all occurring on postoperative day 3 or later. CONCLUSION: After outpatient parathyroidectomy, a specific calcium protocol has been verified that elimi- nates development of symptomatic hypocalcemia in Ͼ92% of patients, identifies patients at high risk for hypocalcemia, and allows self-medication with confidence in a predictable fashion for those patients in whom symptoms develop.

  • Minimally Invasive Parathyroidectomy Versus Bilateral Neck Exploration for Primary Hyperparathyroidism
    Minimally Invasive Parathyroidectomy Versus Bilateral Neck Exploration for Primary Hyperparathyroidism Amanda M. Laird, MD*, Steven K. Libutti, MD KEYWORDS Primary hyperparathyroidism Parathyroidectomy Intraoperative parathyroid hormone Surgery Minimally invasive parathyroidectomy KEY POINTS The gold-standard surgical management of primary hyperparathyroidism (10HPT) is cer- vical exploration and identification of all 4 parathyroid glands. Imaging techniques, including ultrasound, sestamibi scans, and 4D-CT scans, have made identification of single parathyroid adenomas possible. Intraoperative parathyroid hormone (PTH) monitoring is a method to confirm biochemical cure before a patient leaves the operating room. There is some debate surrounding optimal surgical management of 10HPT because cure rates between minimally invasive parathyroidectomy (MIP) and bilateral neck exploration (BNE) are equivalent. Advantages of MIP include reduced operative time, reduced recovery time, less postop- erative pain, and lower complication rate with respect to injury to parathyroid glands and recurrent laryngeal nerves. INTRODUCTION 10HPT is a common disease, with a prevalence as high as 3%.1 Many advances in the surgical management of 10HPT have been made since the first parathyroidectomy was performed by Felix Mandl in 1925.2 Traditional surgical management consists of identification of all 4 parathyroid glands through a transverse cervical incision.3 Bet- ter understanding of the disease, interest in the practice of endocrine neck surgery, The authors have nothing to disclose.

Also, the occurrence of thyroid disease observed in patients with hyperparathyroidism is poorly Thyroidectomy understood and the incidence of cancer is controversial. The aim of the present study was to report the ex- perience of a single center in the surgical treatment of renal hyperparathyroidism and to analyse the role of thyroid and thymus surgery in association with parathyroidectomy. Materials and methods: We analysed parathyroid surgery data, considering patient demographics, such as age and gender, and surgical procedure data, such as type of hyperparathyroidism, associated thyroid or thymus surgery, surgical duration and mediastinal recurrence. Histopathological results of thyroid and thymus samples were also analysed. Results: Medical records of 109 patients who underwent parathyroidectomy for secondary hyperparathyroidism were reviewed. On average, thymectomy did not have impact on time of parathyroidectomy (p = 0.62) even when thyroidectomy was included (p = 0.91).

The American Association of Endocrine Surgeons (AAES) Guidelines for Definitive Management of Primary Hyperparathyroidism ABSTRACT Importance Primary hyperparathyroidism (pHPT) is a common clinical problem for which the only definitive management is surgery. Surgical management has evolved considerably during the last several decades. Objective To develop evidence-based guidelines to enhance the appropriate, safe, and effective practice of parathyroidectomy. Evidence Review A multidisciplinary panel used PubMed to reviewed the medical literature from January 1, 1985, to July 1, 2015. Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Findings Initial evaluation should include 25-hydroxyvitamin D measurement, 24-hour urine calcium measurement, dual-energy x-ray absorptiometry, and supplementation for vitamin D deficiency. Parathyroidectomy is indicated for all symptomatic patients, should be considered for most asymptomatic patients, and is more cost-effective than observation or pharmacologic therapy.
