RESUMEN
Clinical and biochemical presentation of adrenal tumors may rarely conflict with their histologic features. In the present report, we describe a rare case of adrenal neoplasm clinically and biochemically labeled as pheochromocytoma which at histologic examination resulted adrenal cortical tumor. The neoplasm was examined with the electron microscope which revealed the presence of electron-dense neuroendocrine-type granules next to intracytoplasmic lipid droplets. The patient underwent laparoscopic left adrenalectomy which leads to normalization of 24 h urinary metanephrine and normetanephrine. This exceptional entity should be taken into consideration when the clinical and laboratory features conflict with the histological examination. The pathologist can clarify the mixed nature of the tumor by means of the identification of neuroendocrine granules at the electron microscope examination.

INTRODUCTION: The COVID-19 pandemic has limited the availability of healthcare resources for non-COVID patients and decreased elective surgeries, including thyroidectomy. Despite the prioritization of surgical procedures, it has been reported that thyroidectomy for thyroid cancer (TCa) was adversely impacted. We assessed the impact of the pandemic on the surgical activities of two high-volume referral centers. MATERIALS AND METHODS: Patients operated at two National Referral Centers for Thyroid Surgery between 03/01/2020 and 02/28/2021 (COVID-19 period) were included (P-Group). The cohort was compared with patients operated at the same Centers between 03/01/2019 and 02/29/2020 (pre-COVID-19 pandemic) (C-Group). RESULTS: Overall, 7017 patients were included: 2782 in the P-Group and 4235 in the C-Group. The absolute number of patients with TCa was not significantly different between the two groups, while the rate of malignant disease was significantly higher in the P-Group (1103/2782 vs 1190/4235) (P < 0.0001). Significantly more patients in the P-Group had central (237/1103 vs 232/1190) and lateral (167/1103 vs 140/1190) neck node metastases (P = 0.001). Overall, the complications rate was significantly lower (11.9% vs 15.1%) and hospital stay was significantly shorter (1.7 ± 1.5 vs 1.9 ± 2.2 days) in the P-Group (P < 0.05). CONCLUSION: The COVID-19 pandemic significantly decreased the overall number of thyroidectomies but did not affect the number of operations for TCa. Optimization of management protocols, due to limited resource availability for non-COVID patients, positively impacted the complication rate and hospital stay.

Obesity's role in thyroid cancer development is still debated, as well as its association with aggressive histopathological subtypes (AHSs). To clarify the link between Body Mass Index (BMI) and AHS of differentiated thyroid carcinoma (DTC), we evaluated patients who underwent thyroidectomy for DTC from 2020 to 2022 at four European referral centres for endocrine surgery. Based on BMI, patients were classified as normal-underweight, overweight, or obese. AHSs were defined according to 2022 WHO guidelines. Among 3868 patients included, 34.5% were overweight and 19.6% obese. Histological diagnoses were: 93.6% papillary (PTC), 4.8% follicular (FTC), and 1.6% Hürthle cell (HCC) thyroid carcinoma. Obese and overweight patients with PTC had a higher rate of AHSs (p = 0.03), bilateral, multifocal tumours (p = 0.014, 0.049), and larger nodal metastases (p = 0.017). In a multivariate analysis, BMI was an independent predictor of AHS of PTC, irrespective of gender (p = 0.028). In younger patients (<55 years old) with PTC > 1 cm, BMI predicted a higher ATA risk class (p = 0.036). Overweight and obese patients with FTC had larger tumours (p = 0.036). No difference was found in terms of AHS of FTC and HCC based on BMI category. Overweight and obese patients with PTC appear to be at an increased risk for AHS and aggressive clinico-pathological characteristics.
RESUMEN
In 2016, the American Thyroid Association published a statement on remote-access thyroid surgery claiming that it should be reserved to patients with thyroid nodule ≤ 3 cm, thyroid lobe < 6 cm and without thyroiditis. We retrospectively enrolled all patients who underwent robotic transaxillary thyroidectomy between February 2012 and March 2022. We compared surgical outcomes between patients who presented a thyroid gland with a nodule ≤ 3 cm, thyroid lobe < 6 cm and without thyroiditis (Group A) and patients without these features (Group B). The rate of overall complications resulted comparable (p = 0.399), as well as the operative time (p = 0.477) and the hospital stay (p = 0.305). Moreover, bleeding resulted associated to thyroid nodule > 3 cm (p = 0.015), although all bleedings but one occurred in the remote-access site from the axilla to the neck. In experienced hands, robotic transaxillary thyroidectomy is feasible and safe even in patients with large thyroid nodules or thyroiditis.

Background: Postoperative cervical haematoma represents an infrequent but potentially life-threatening complication of thyroidectomy. Since this complication is uncommon, the assessment of risk factors associated with its development is challenging. The main aim of this study was to identify the risk factors for its occurrence. Methods: Patients undergoing thyroidectomy in seven high-volume thyroid surgery centers in Europe, between January 2020 and December 2022, were retrospectively analysed. Based on the onset of cervical haematoma, two groups were identified: Cervical Haematoma (CH) Group and No Cervical Haematoma (NoCH) Group. Univariate analysis was performed to compare these two groups. Moreover, employing multivariate analysis, all potential independent risk factors for the development of this complication were assessed. Results: Eight thousand eight hundred and thirty-nine patients were enrolled: 8,561 were included in NoCH Group and 278 in CH Group. Surgical revision of haemostasis was performed in 70 (25.18%) patients. The overall incidence of postoperative cervical haematoma was 3.15% (0.79% for cervical haematomas requiring surgical revision of haemostasis, and 2.35% for those managed conservatively). The timing of onset of cervical haematomas requiring surgical revision of haemostasis was within six hours after the end of the operation in 52 (74.28%) patients. Readmission was necessary in 3 (1.08%) cases. At multivariate analysis, male sex (P < 0.001), older age (P < 0.001), higher BMI (P = 0.021), unilateral lateral neck dissection (P < 0.001), drain placement (P = 0.007), and shorter operative times (P < 0.001) were found to be independent risk factors for cervical haematoma. Conclusions: Based on our findings, we believe that patients with the identified risk factors should be closely monitored in the postoperative period, particularly during the first six hours after the operation, and excluded from outpatient surgery.
RESUMEN
BACKGROUND: Adrenocortical carcinoma (ACC) is a rare malignant tumor with a poor prognosis. Radical surgical resection with negative margins represents the only opportunity for a potential cure. This review provides a critical assessment of the existing studies regarding the surgical approaches for the treatment of ACC. METHODS: This review was performed according to criteria reported in the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. The research was carried out using the PubMed electronic library. This review is limited to comparative studies evaluating minimally invasive adrenalectomy (MIA) and open adrenalectomy (OA) in adult patients affected by ACC. RESULTS: A total of 14 studies were selected for the review, reporting that 2574 patients underwent adrenal surgery for ACC: 1779 (69.1%) by means of OA and 795 (30.8%) by means of MIA. Six studies considered OA to be superior to MIA, whereas eight studies reported that MIA is as effective as OA in highly selected cases. All studies were retrospective with a heterogenous selection of patients. CONCLUSIONS: Data regarding the management of MIA are scarce, heterogenous, and mainly based on retrospective studies. OA remains the gold standard approach for the management of ACC; however, MIA may play a role in selected cases treated in high volume institutions with experienced surgeons.
RESUMEN
BACKGROUND: Energy-based devices are surgical devices increasingly utilized for thyroid surgery, owing to a reduction of operative time and surgical related complications. The aim of the study is to evaluate whether the use of energy-based devices could improve the complication rate in pediatric thyroid surgery. METHODS: This is a retrospective observational study. We identified 177 consecutive pediatric patients (Group A) with thyroid diseases, surgically treated by energy-based devices and 237 patients (Group B) treated by conventional clamp and tie technique and matched for sex, age and indication for surgery. Transient and permanent complications rate, operative time and length of hospital stay were compared between the two groups. RESULTS: Patients of Group A experienced a lower complication rate compared to Group B. Particularly, transient (11.3 vs. 19% p < 0.05) and permanent post operative hypoparathyroidism (1.7 vs. 5.5%, p < 0.05) were lower in Group A. Moreover, operative time was also shorter in Group A compared to Group B and this difference was statistically significant in patients who performed total thyroidectomy alone and total thyroidectomy associated with central compartment neck dissection (p < 0.05). Length of hospital stay was lower in Group A than in Group B, but this difference was statistically significant only for microfollicular lesion (p < 0.05). CONCLUSION: The use of energy-based devices has a key role in reducing surgical related complications, particularly transient and permanent hypoparathyroidism, operative time and length of hospital stay in pediatric patients treated with thyroid surgery. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective comparative study.
