Retracting the thyroid matters: Who develops asymptomatic transient thyrotoxicosis after parathyroidectomy.

BACKGROUND: Hyperthyroidism after parathyroidectomy is not a well-understood complication. We sought to determine the incidence and risk factors of hyperthyroidism after parathyroidectomy. MATERIALS AND METHODS: This is a prospective study of 91 patients undergoing parathyroidectomy. Pre- and post-operative thyroid-stimulating hormone(TSH) and free thyroxine(T4) levels at two-week follow-ups were collected. Bivariate analyses were conducted to compare demographics, laboratory results, and intraoperative findings between patients with normal and suppressed post-parathyroidectomy TSH. RESULTS: Twenty-two(24.2 â€‹%) patients had suppressed TSH after parathyroidectomy and 2(2.2 â€‹%) reported symptoms of hyperthyroidism. All hyperthyroidism resolved within 6 weeks. No patients required medical treatment. Compared to the normal TSH group, the suppressed TSH group had significantly more bilateral explorations(91.0 â€‹% vs. 58.0 â€‹%, p â€‹= â€‹0.006), and superior parathyroid resections(95.5 â€‹% vs. 65.2 â€‹%, p â€‹= â€‹0.006). CONCLUSION: Transient hyperthyroidism is common following parathyroidectomy, which is likely associated with intraoperative thyroid manipulation. Gentle retraction of thyroid glands in parathyroidectomy is warranted, especially during superior parathyroid gland resection.

Outpatient parathyroidectomy in the pediatric population: An 18-year experience.

BACKGROUND: Parathyroidectomy for primary hyperparathyroidism (pHPT) is safely performed in the outpatient setting in the adult population. However, concern that children and adolescents have higher complication rates and are unable to recognize and communicate symptoms of hypocalcemia has limited same-day discharges in the pediatric population. METHODS: Nineteen patients aged 8-18 years (14.1 ± 0.7) underwent outpatient parathyroidectomy for pHPT by a single high-volume endocrine surgeon from 2002-2020. Patient demographics, disease, operations, and complications were reviewed. RESULTS: Sixteen of 19 patients were symptomatic with fatigue (62.5%), joint pain (37.5%) and nephrolithiasis (18.7%) most common. Mean preoperative Ca and PTH were 11.7 ± 0.3 mg/dL and 102.3 ± 11.8pg/mL, respectively. Ten of 19 had a single adenoma and 9 had multigland hyperplasia including one MEN1 and one MEN2A patient. We performed 11 four-gland explorations, 8 unilateral parathyroidectomies; including 9 transcervical thymectomies, 1 total thyroidectomy, and 1 bilateral central neck dissection. Mean 6-month postoperative Ca and PTH levels were 9.5 ± 0.3 mg/dL (range 7.3-10.3) and 29±5.0pg/mL (range 6.3-77), respectively. One patient developed permanent hypoparathyroidism and 1 had temporary hypocalcemia. No temporary or permanent hoarseness, unplanned same-day admission, wound complications, or Emergency Department visits occurred. CONCLUSION: Outpatient parathyroidectomy can be safely and effectively performed in pediatric patients with primary HPT. LEVEL OF EVIDENCE: Treatment Study, Level III.

Outpatient thyroidectomy in the pediatric population.

Preoperative optimization and patient education have allowed for the transition of thyroid surgery to the outpatient setting over the last few decades. Performing these operations in the outpatient setting has proven to be cost-effective and safe in the adult population. The purpose of this study is to evaluate the safety and efficacy of outpatient thyroid surgery in the pediatric population. A retrospective review from December 2015 to February 2019 of patients under the age of 18 years of age undergoing thyroidectomy performed by two endocrine surgeons at a large academic was performed. There were 55 consecutive operations performed in 51 patients for thyroid pathology, two were excluded as they were inpatient procedures. Cases were reviewed for complications, unplanned same-day admission, 30-day admission, unplanned reoperation, and death. Mean age was 15 ± 0.3 years (range 9-18 years), 79% of the patients were female. Operations were performed for Graves' disease (n = 29), thyroid cancer (n = 9), thyroid nodule (n = 6), multinodular goiter (n = 4), Hashimoto's disease (n = 3), and toxic adenoma (n = 2). Operations performed included: total thyroidectomy (n = 36), thyroid lobectomy (n = 13), total thyroidectomy with lymph node dissection (n = 2), and lateral neck dissection (n = 2). All patients were discharged home within 6 h after completion of the operation. Five (9.4%) patients had transient hypoparathyroidism, with parathyroid hormone levels <10 pg/mL immediately postoperatively. One patient (1.9%) developed a postoperative hematoma on postoperative day six and required reoperation and readmission. Two patients (3.8%) had permanent hypoparathyroidism and one had transient hoarseness (1.9%). There were otherwise no readmissions or ED visits. In conclusion, outpatient thyroid surgery is safe and effective for pediatric patients.

Reducing cost and improving operating room efficiency: examination of surgical instrument processing.

BACKGROUND: Operating room efficiency can be compromised because of surgical instrument processing delays. We observed that many instruments in a standardized tray were not routinely used during thyroid and parathyroid surgery at our institution. Our objective was to create a streamlined instrument tray to optimize operative efficiency and cost. MATERIALS AND METHODS: Head and neck surgical instrument trays were evaluated by operating room team leaders. Instruments were identified as either necessary or unnecessary based on use during thyroidectomies and parathyroidectomies. The operating room preparation time, tray weights, number of trays, and number of instruments were recorded for the original and new surgical trays. Cost savings were calculated using estimated reprocessing cost of $0.51 per instrument. RESULTS: Three of 13 head and neck trays were converted to thyroidectomy and parathyroidectomy trays. The starting head and neck surgical set was reduced from two trays with 98 total instruments to one tray with 36 instruments. Tray weight decreased from 27 pounds to 10 pounds. Tray preparation time decreased from 8 min to 3 min. The new tray saved $31.62 ($49.98 to $18.36) per operation in reprocessing costs. Projected annual savings with hospitalwide implementation is over $28,000.00 for instrument processing alone. Unmeasured hospital savings include decreased instrument wear and replacement frequency, quicker operating room setup, and decreased decontamination costs. CONCLUSIONS: Optimizing surgical trays can reduce cost, physical strain, preparation time, decontamination time, and processing times, and streamlining trays is an effective strategy for hospitals to reduce costs and increase operating room efficiency.

Mammography capacity impact on screening rates and breast cancer stage at diagnosis.

BACKGROUND: Mammography capacity in the U.S. reportedly is adequate, but has not been examined in nonmetropolitan areas. This study examined the relationships between in-county mammography facilities and rates of mammography screening and late-stage diagnosis of breast cancers. METHODS: The association between a mammography facility in the county of residence (2002-2004) and the odds of screening within 2 years were examined (in 2007) among Texas women aged >40 years who responded to the 2004 Behavioral Risk Factor Surveillance System survey, using multivariate logistic regression to control for age, race, ethnicity, education, income, self-reported health, insurance, and usual source of care. Similarly, the association between an in-county mammography facility and the odds of diagnosis with locally advanced or disseminated disease was examined among Texas women aged >40 years who developed breast cancer in 2004. RESULTS: Half of the 254 counties in Texas had no mammography facility. After controlling for confounding factors, an in-county facility was associated with significantly higher odds of screening (OR=3.27; p=0.03) and lower odds of late-stage breast cancer at diagnosis (OR=0.36; 95% CI=0.26-0.51; p<0.001). The risks of late-stage diagnosis were higher for African-American women (OR=1.52; 95% CI=1.22-1.89; p<0.001) and Hispanic women (OR=1.23; 95% CI=0.99-1.53; p=0.06) than for white women. CONCLUSIONS: Although mammography capacity in the U.S. may be adequate on average, the unequal distribution of facilities results in large rural areas without facilities. Screening rates in these areas are suboptimal and are associated with late-stage diagnosis of breast cancer.
