Cervical hematoma following an endocrine surgical procedure: The MD Anderson experience.

BACKGROUND: Airway compromise from postoperative neck hematoma remains the most feared complication after cervical endocrine operative procedures. Events are rare and potentially lethal, and clear multidisciplinary guidelines for management of these patients are lacking. The aim of our study was to review the experience of a tertiary cancer center in this scenario. METHODS: Data prospectively collected over a 10-year period, between 2005 and 2014, were retrospectively analyzed. We included all adult patients who had had a neck operation and needed reoperation for postoperative neck hematoma after an endocrine procedure. We excluded pediatric patients and cases with incomplete records. RESULTS: The inclusion criteria were met for 21 patients (21/2,930; 0.7%). The median age at operation was 56.2 years (SD: 16.7). The M:F ratio was 1:2. All 21 patients presented with a neck swelling at the time of reoperation. Eight of 21 patients (38%) underwent emergency bedside clot evacuation. Presentation was within 6 hours for two thirds (14/21) of the patients; the remaining one third of the patients had the hematoma develop during the evening/night (from 1700-0500). The mean estimated hematoma size was 98 cc (SD: 58). A source of bleeding was identified in 12 of 21 cases (57%). A total of 15.8% of patients had an airway classified as difficult/awkward under the American Society of Anesthesiologists classification for their wound re-exploration. CONCLUSION: Postoperation, increased vigilance is needed for the first 6 hours to detect patients with neck swelling. Emergency drainage by the bedside was performed in 38% of patients. A difficult airway was uncommon in our series.

Outpatient minimally invasive parathyroidectomy is safe for elderly patients.

BACKGROUND: Elderly patients with primary hyperparathyroidism (PHPT) are often not referred for surgical intervention because of concern of comorbid conditions that may increase perioperative complications. Because PHPT is more common in the elderly, we sought to compare indications and complications of minimally invasive parathyroidectomy in patients 70 years of age and older (elderly) with their younger counterparts. STUDY DESIGN: A review was conducted of a prospectively collected database of all patients undergoing parathyroidectomy on our endocrine surgery service. Data collected included patient demographic, biochemical pathologic, and operative findings. Wilcoxon rank sum and chi-square tests were used for comparisons. RESULTS: Three hundred eighty-eight patients with PHPT recently underwent parathyroidectomy over a 3-year period (elderly, n=101; younger, n=287). The elderly cohort had significantly higher median preoperative creatinine (elderly, 2.0 mg/dL; younger,1.0 mg/dL; p=0.002) and parathyroid hormone (elderly, 145 pg/mL; younger, 123 pg/mL; p=0.026) levels. The elderly cohort also had more severe osteoporosis, with a significantly worse median bone mineral density T-score (elderly, -2.5; younger, -1.8; p<0.001). The rate of postoperative complications was similarly low in both groups (elderly, 5.9%; younger, 3.5%; p=0.38). CONCLUSIONS: Minimally invasive parathyroidectomy for PHPT can be performed as safely in elderly patients as in their younger counterparts. Elderly patients with PHPT are more likely to have osteoporosis and higher creatinine levels at the time of surgical referral. Additional study of the role of earlier intervention is warranted.

A novel nomenclature to classify parathyroid adenomas.

BACKGROUND: A uniform and reliable description of the exact locations of adenomatous parathyroid glands is necessary for accurate communications between surgeons and other specialists. We developed a nomenclature that provides a precise means of communicating the most frequently encountered parathyroid adenoma locations. METHODS: This classification scheme is based on the anatomic detail provided by imaging and can be used in radiology reports, operative records, and pathology reports. It is based on quadrants and anterior-posterior depth relative to the course of the recurrent laryngeal nerve and the thyroid parenchyma. The system uses the letters A-G to describe exact gland locations. RESULTS: A type A parathyroid gland is a gland that originates from a superior pedicle, lateral to the recurrent laryngeal nerve compressed within the capsule of the thyroid parenchyma. A type B gland is a superior gland that has fallen posteriorly into the tracheoesophageal groove and is in the same cross-sectional plane as the superior portion of the thyroid parenchyma. A type C gland is a gland that has fallen posteriorly into the tracheoesophageal groove and on a cross-sectional view lies at the level of or below the inferior pole of the thyroid gland. A type D gland lies in the midregion of the posterior surface of the thyroid parenchyma, near the junction of the recurrent laryngeal nerve and the inferior thyroid artery or middle thyroidal vein; because of this location, dissection is difficult. A type E gland is an inferior gland close to the inferior pole of the thyroid parenchyma, lying in the lateral plane with the thyroid parenchyma and anterior half of the trachea. A type F gland is an inferior gland that has descended (fallen) into the thyrothymic ligament or superior thymus; it may appear to be "ectopic" or within the superior mediastinum. An anterior-posterior view shows the type F gland to be anterior to the trachea. A type G gland is a rare, truly intrathyroidal parathyroid gland. CONCLUSIONS: A reproducible nomenclature can provide a means of consistent communication about parathyroid adenoma location. If uniformly adopted, it has the potential to reliably communicate exact gland location without lengthy descriptions. This system may be beneficial for surgical planning as well as operative and pathology reporting.
