RESUMO
BACKGROUND: Although uncommon, adrenal hemorrhage has multiple etiologies. Because clinical characteristics, management, and outcomes of patients with adrenal hemorrhage are inadequately described, we examined the underlying etiology, need for intervention, evolution of imaging characteristics, and adequacy of subsequent evaluation. METHODS: We performed a retrospective review of patients diagnosed with adrenal hemorrhage (radiologist-confirmed density consistent with hemorrhage on computed tomography) from 2005 to 2021 at a university-based institution. Demographic characteristics, hemorrhage etiology, and subsequent follow-up were analyzed. RESULTS: Of 193 adrenal hemorrhage patients, the mean age was 49.2 ± 18.3 years, and 35% were female. Clinical presentations included trauma (47%), abdominal or flank pain (28%), incidental findings on imaging acquired for other reasons (12%), postoperative complication (8%), or shock (3%). Hemorrhage outside of the gland was present in 62% of patients. Unilateral hemorrhage was more frequent (93%) than bilateral (7%). A total of 12% of patients had nodules, but only 70% of these were identified on initial imaging, and only 43% had hormonal evaluation. Of 7 patients who had adrenalectomy or biopsy, pathology was either benign (57%) or nonadrenal malignancy (43%). No adrenocortical carcinomas were identified. Follow-up imaging was performed in 56% of patients and revealed decreased, stable, resolved, or increased adrenal hemorrhage size in 39%, 19%, 30%, and 12% of patients, respectively. CONCLUSION: Adrenal hemorrhage is secondary to multiple etiologies, most commonly trauma. In the setting of adrenal hemorrhage, many adrenal nodules were not identified on initial imaging. Only a minority of patients with nodules underwent "complete" biochemical evaluation. Follow-up imaging may improve the identification of underlying nodules needing hormonal evaluation.

BACKGROUND: Thoracic duct leaks occur in up to 5% of left lateral neck dissections. No one imaging modality is routinely used to identify the thoracic duct intraoperatively. The goal of our study was to evaluate the efficacy and safety of indocyanine green lymphangiography for intraoperative identification of the thoracic duct compared to traditional methods using ambient and evaluate the optimal timing of indocyanine green administration. METHODS: We enrolled all patients who underwent left lateral neck dissection at our institution from 2018 to 2022 in this prospective clinical trial. After indocyanine green injection into the dorsum of the foot, we performed intraoperative imaging was performed with a near-infrared fluorescence camera. We reported the data using descriptive statistics. RESULTS: Of the 42 patients we enrolled, 14 had prior neck surgery, and 3 had prior external beam radiation. We visualized the thoracic duct with ambient light in 48% of patients and with near-infrared fluorescence visualization in 64%. In 17% of patients, we could identify the thoracic duct only using near-infrared fluorescence visualization, which occurred within 3 minutes of injection, and were required to re-dose 5 patients. We visualized the thoracic duct with near-infrared fluorescence in all patients with prior neck radiation and 77% of patients with prior neck surgery. One adverse reaction occurred (hypotension), and 5 intraoperative thoracic duct injuries occurred that were ligated. There with no chylous fistulas postoperatively. CONCLUSION: This trial demonstrates that near-infrared fluorescence identification of the thoracic duct is feasible and safe with indocyanine green lymphangiography, even in patients with prior neck surgery or radiation.

Context: Parathyroid tissue is one of the few tissues to have strong near-infrared (NIR) autofluorescence, which has been exploited to improve intraoperative parathyroid identification. The US Food and Drug Administration has approved 2 devices for this purpose. Adrenal glands can be difficult to distinguish from surrounding fat, an issue during total adrenalectomy. Objective: We hypothesized adrenal tissue may also possess considerable NIR autofluorescence. Methods: Resected patient adrenal specimens were examined after robotic adrenalectomy with an NIR camera intraoperatively. Patients did not receive fluorescent dye. Images were taken of both gross and sectioned specimens. Post hoc image analysis was performed with ImageJ software. Confocal microscopy was performed on selected tissues using immunofluorescence and hematoxylin-eosin staining. Results: Resected tissue was examined from 22 patients undergoing surgery for pheochromocytomas (6), primary aldosteronism (3), adrenocorticotropin-independent hypercortisolism (10), and a growing or suspicious mass (3). Normal adrenal tissue demonstrated strong NIR autofluorescence. The intensity ratio compared to background (set as 1) for gross images was 2.03â ±â 0.51 (Pâ <â .0001) compared to adjacent adipose of 1.24â ±â 0.18. Autofluorescence from adrenal tumors was also detected at variable levels of intensity. Cortisol-producing tumors had the highest fluorescence ratio of 3.01â ±â 0.41. Confocal imaging localized autofluorescence to the cytosol, with the highest intensity in the zona reticularis followed by the zona fasciculata. Conclusion: Normal and abnormal adrenal tissues possess natural NIR autofluorescence. Highest autofluorescence levels were associated with cortisol-producing tumors. Confocal imaging demonstrated the highest intensity in the zona reticularis. NIR cameras may have the potential to improve identification of adrenal tissue during surgery.
RESUMO
CONTEXT: Adrenal tumors in noncancer patients are common. OBJECTIVE: Evaluate performance of 18F-fluorodeoxyglucose positron emission tomography computed tomography (18F-FDG-PET/CT) in distinguishing between benign and malignant adrenal tumors. DESIGN: Retrospective chart review 2010-2019. SETTING: Academic institution. PATIENTS: One hundred and seventeen noncancer patients, defined as having no history of cancer or with cancer in remission for ≥5 years, completed 18F-FDG-PET/CT to evaluate adrenal masses, with pathologic diagnoses or imaging follow-up (≥12 months). INTERVENTION: 18F-FDG-PET/CT of 117 indeterminate adrenal masses. MAIN OUTCOME MEASURES: Receiver operator characteristic curve of the ratios of adrenal lesion standardized uptake value (SUV)max to liver SUVmean and of adrenal lesion SUVmax to aortic arch blood pool SUVmean were constructed. RESULTS: Seventy benign and 47 malignant masses (35 adrenocortical carcinomas [ACCs], 12 adrenal metastases) were identified. Malignant masses had higher median liver SUV and blood pool SUV ratios than benign masses (6.2 and 7.4 vs 1.4 and 2.0, P < .001). Median liver and blood pool SUV ratios of ACC (6.1 and 7.3, respectively) and metastases (6.7 and 7.7, respectively) were higher than those of than adenomas (1.4 and 2.2, P < .05 for all comparisons). Optimal liver SUV ratio to discern between benign and malignant masses was 2.5, yielding 85% sensitivity, 90% specificity, and 7 false negative results (including 3 ACCs). Optimal blood pool SUV ratio was 3.4, yielding 83% sensitivity, 90% specificity, and 8 false negative results (including 4 ACCs). CONCLUSION: When used in conjunction with other clinical assessments, 18F-FDG-PET/CT can be a valuable tool in evaluating adrenal masses in noncancer patients.

BACKGROUND: The traditional definition of cure after parathyroidectomy (PTX) for primary hyperparathyroidism is normocalcemia. Our hypothesis was that early postoperative levels of serum calcium and parathyroid hormone after PTX would have predictive value for later recurrence. METHODS: We performed a retrospective study of 1,146 patients with primary hyperparathyroidism who underwent PTX and had long-term biochemical follow-up. The first postoperative serum level of calcium and parathyroid hormone values were used to categorize patients into the following four early biochemical response groups: (1) complete response (normal calcium and normal parathyroid hormone), (2) partial response with hyperparathormonemia (normal calcium and increased parathyroid hormone), (3) partial response with hypercalcemia (increased calcium and normal parathyroid hormone), and (4) non-response (increases in both calcium and parathyroid hormone). Incidences of recurrent hypercalcemia and recurrent primary hyperparathyroidism >6 months after operation were then analyzed. RESULTS: The overall rate of any elevated serum levels of calcium and any increase in serum levels of parathyroid hormone during >6-month follow-up was 9.8% (112 of 1146), with 6.6% (57 of 861) for group 1, 27% (35 of 129) for group 2, and 16% (20 of 127) for group 3 (P < .02). Partial biochemical responses with either increased serum calcium or increased parathyroid hormone levels were the strongest predictors of any episode of increased serum levels of calcium after 6 months and was associated with 2.7× to 4.3× the risk of recurrent primary hyperparathyroidism, respectively. CONCLUSION: This study demonstrates the importance of measuring parathyroid hormone in the early postoperative period to better predict later recurrent primary hyperparathyroidism.

Importance: With the potential for severe adverse effects of hypercortisolism, the need to limit the development and unrecognized persistence of sequelae from cortisol excess is of great importance on individual and population health levels. This review discusses the evaluation and treatment of patients with hypercortisolism. Pathophysiology; pitfalls in the diagnosis of hypercortisolism; and preoperative, perioperative, and postoperative management considerations are discussed. The association of hypercortisolism with population health and the potential role surgeons and surgery can play in the future of patients with hypercortisolism are also discussed. Higher-level considerations are put forth to encourage a long-term view of future work needed to optimally care for these patients. Observations: Although classic signs and symptoms of hypercortisolism are evident in some patients, mild autonomous cortisol secretion is likely more prevalent and more difficult to detect despite having the potential to cause significant adverse effects, such as increased risk of mortality, and overt hypercortisolism. With treatment, some adverse effects of hypercortisolism may resolve, although not in all patients. Thus, the need for early diagnosis and treatment is of great importance. Conclusions and Relevance: More attention in the future on early treatment of hypercortisolism, whether subclinical or overt, and prevention of adverse effects is warranted for the sake of the individual and the population.

BACKGROUND: Postoperative radioactive iodine (RAI) administration is widely utilized in patients with differentiated thyroid cancer. While beneficial in select patients, it is critical to recognize the potential negative sequelae of this treatment. The prevention, diagnosis, and management of the salivary and lacrimal complications of RAI exposure are addressed in this consensus statement. METHODS: A multidisciplinary panel of experts was convened under the auspices of the American Head and Neck Society Endocrine Surgery and Salivary Gland Sections. Following a comprehensive literature review to assess the current best evidence, this group developed six relevant consensus recommendations. RESULTS: Consensus recommendations on RAI were made in the areas of patient assessment, optimal utilization, complication prevention, and complication management. CONCLUSION: Salivary and lacrimal complications secondary to RAI exposure are common and need to be weighed when considering its use. The recommendations included in this statement provide direction for approaches to minimize and manage these complications.

Primary hyperparathyroidism (pHPT) is associated with familial syndromes such as multiple endocrine neoplasia type 1 (MEN1), 2A (MEN2A), MEN-like syndromes (CDKN1B), and CDC73-related disorder (hyperparathyroidism - jaw tumor syndrome (HPJT)). Familial hypocalciuric hypercalcemia (FHH) caused by CASR variants is an important differential diagnosis for pHPT. In order to evaluate the contribution of hereditary causes to pHPT in patients encountered in a specialized clinic, we conducted a retrospective study on patients with pHPT that underwent germline genetic testing. We evaluated 46 patients referred to a Cancer Genetics Clinic. Reasons for referral were young age (age < 40) for 29 patients (63%), multi-gland disease for 23 patients (50%), and a positive family history of pHPT for 11 patients (24%). All 46 patients underwent genetic evaluation. A total of 11 rare variants were found (CASR (4), CDC73 (2), MEN1 (2) CDKN1B (1), and RET (2)). One MEN1 variant was classified as pathogenic, and all others were variants of uncertain significance (VUS). All patients with CASR variants had clinical features of FHH and were counselled against parathyroidectomy. Both patients with CDC73 variants were counselled about recurrence of pHPT and parathyroid cancer. Neither of the RET variants were MEN2-associated. The CDKN1B variant was regarded as a true VUS and no action was taken. In this study, genetic testing impacted clinical care in 7 (15%) patients. We suggest that all patients < 40 years of age, with multi-gland disease, single gland disease refractory to treatment, and a positive family history for pHPT or associated tumors should be considered for genetic evaluation.

BACKGROUND: Safe performance of laparoscopic transabdominal adrenalectomy requires the application of a complex body of knowledge and skills, which are difficult to define, teach, and measure. This qualitative study aims to characterize expert behaviors, decisions, and other cognitive processes required to perform laparoscopic transabdominal adrenalectomy. METHOD: Hierarchical and cognitive task analyses for right and left laparoscopic transabdominal adrenalectomy were performed using semi-structured interviews and field observations of experts. Verbal data was supplemented with published literature, coded and thematically analyzed using constructivist grounded-theory by 2 independent reviewers. RESULTS: A conceptual framework was synthesized. Sixty-eight tasks, 46 cognitive behaviors, and 52 potential errors were identified and categorized into 8 procedural steps and 8 fundamental principles: anticipation, exposure, teamwork or communication, physiology, dissection techniques, oncologic margins, tactical modification, and error recovery. Experts emphasized the importance of creating a 3-dimensional mental model of the anatomy or pathology (eg, aberrant vessels, tumor location) that is consistently fine-tuned throughout the operation, with conscious awareness of danger zones (eg, medial arc). Despite variations in dissection techniques, experts highlighted 2 themes: macrodissection and microdissection, with emphasis on nonlinear motions and effective transitions between the 2 when appropriate. CONCLUSION: This study defines behaviors and competencies that are essential to performing laparoscopic transabdominal adrenalectomy effectively and safely.
