Prophylactic central lymph node dissection for low-risk papillary thyroid cancer-Impact on subsequent therapy.

Background: For small papillary thyroid cancers (PTCs) with no lateral nodal involvement, American Thyroid Association guidelines recommend performing prophylactic central lymph node dissection (pCLND) if it influences further management. Our cohort study explored to what extent performing pCLND for small PTCs can de-escalate subsequent therapy including completion thyroidectomy and adjuvant radioactive iodine (RAI) ablation.

Methods: Adults with T1, T2, and cN0 PTCs were identified from 42 centers across the prospectively maintained Australian and New Zealand Thyroid Cancer Registry (ANZTCR) between 2017 and 2023.

Artificial Intelligence for Pre-operative Diagnosis of Malignant Thyroid Nodules Based on Sonographic Features and Cytology Category.

Background: Current diagnosis and classification of thyroid nodules are susceptible to subjective factors. Despite widespread use of ultrasonography (USG) and fine needle aspiration cytology (FNAC) to assess thyroid nodules, the interpretation of results is nuanced and requires specialist endocrine surgery input. Using readily available pre-operative data, the aims of this study were to develop artificial intelligence (AI) models to classify nodules into likely benign or malignant and to compare the diagnostic performance of the models.

Impact of dedicated multidisciplinary service on patient selection and outcomes for surgical treatment of primary aldosteronism.

Background: Primary aldosteronism is the most common surgically curable cause of endocrine hypertension. Management of the unilateral subtype of primary aldosteronism with adrenalectomy requires multidisciplinary input. It is unclear if a dedicated endocrine hypertension service confers better outcomes compared to standard care offered by individual clinicians.

Preoperative serum calcitonin may improve initial surgery for medullary thyroid cancer in patients with indeterminate cytology.

Background: Medullary thyroid cancer (MTC) is rare, with poorer outcomes than differentiated thyroid cancer. We aimed to identify areas for improvement in the pre-operative evaluation of patients with possible MTC in a high-volume endocrine surgery unit in accordance with current practice guidelines. We hypothesised that the selective use of serum calcitonin (sCT) as a biomarker for possible MTC could guide the extent of initial surgical management.

Hypotension in Posterior Retroperitoneoscopic Versus Transperitoneal Laparoscopic Adrenalectomy.

Introduction: Despite preoperative optimization, hemodynamic instability can be a major challenge during adrenalectomy. Even brief episodes of intraoperative hypotension can be associated with ischemia-reperfusion injury. This study aimed to compare intraoperative hemodynamic parameters between posterior retroperitoneoscopic adrenalectomy (PRA) and transperitoneal laparoscopic adrenalectomy (TPA).

Cancer in thyroglossal duct cysts.

Background: Thyroglossal duct cysts (TDC) account for 7% of midline neck swellings. TDC carcinoma (TDCC) is rare, reported in 1% of all TDCs. We aimed to describe the incidence of TDCC, the accuracy of fine needle aspiration cytology (FNAC), and to identify suspicious, predictive ultrasound (USG) features.

Preoperative mineralocorticoid receptor antagonist reduces postoperative hyperkalaemia in patients with Conn syndrome.

Background: The preoperative use of mineralocorticoid receptor antagonists (MRA) in patients with unilateral forms of primary aldosteronism (PA) is not standardized. The current Endocrine Society Guidelines do not specifically recommend MRA treatment before surgery. It is unclear whether preoperative MRA can optimize perioperative blood pressure and potassium control, and reduce the incidence of postoperative hyperkalaemia.

Less extensive surgery for low-risk papillary thyroid cancers post 2015 American Thyroid Association guidelines in an Australian tertiary centre.

Introduction: The 2015 American Thyroid Association guidelines (ATA15) consider hemithyroidectomy (HT) a viable treatment option for low-risk papillary thyroid cancers (PTCs) between 1 and 4 cm. We aimed to examine the impact of ATA15 in a high-volume Australian endocrine surgery unit.

Methods: A retrospective study of all patients undergoing thyroidectomy from January 2010 to December 2019.

Investigation of recurrent laryngeal palsy rates for potential associations during thyroidectomy.

Background: There are many clinical associations and potential mechanisms of injury resulting in recurrent laryngeal nerve palsy (RLNP) after thyroidectomy. One possible cause of RLNP is focal intralaryngeal compression of the recurrent laryngeal nerve (RLN), which may be associated with the tracheal tube (TT). Therefore, we examined current RLNP rates to investigate potential associations, including intralaryngeal, airway, anaesthetic and anthropometric factors.

Anti-Thyroid Antibodies and TSH as Potential Markers of Thyroid Carcinoma and Aggressive Behavior in Patients with Indeterminate Fine-Needle Aspiration Cytology.

Background: Indeterminate fine-needle aspiration cytology (FNAC) imposes challenges in the management of thyroid nodules. This study aimed to examine whether preoperative anti-thyroid antibodies (Abs) and TSH are indicators of thyroid malignancy and aggressive behavior in patients with indeterminate FNAC.

Methods: This was a retrospective study of thyroidectomy patients from 2008 to 2016.

Routine Preoperative Laryngoscopy for Thyroid Surgery Is Not Necessary Without Risk Factors.

Routine preoperative vocal cord (VC) assessment with laryngoscopy in patients undergoing thyroidectomy allows clear documentation of baseline VC function, aids in surgical planning in patients with palsies, and facilitates interpretation of intraoperative neuromonitoring (IONM) findings. We aimed to determine the incidence of preoperative vocal cord palsy (VCP); to evaluate the associated risk factors for preoperative VCP; and to calculate the cost-savings potential of implementing a selective approach. Patients with a pre-thyroidectomy VC assessment by fiberoptic laryngoscopy were retrospectively recruited from the Monash University Endocrine Surgery Unit database from 2000 to 2018.

Adrenal incidentaloma follow-up is influenced by patient, radiologic, and medical provider factors: A review of 804 cases.

Background: The majority of adrenal incidentalomas are benign, although some are large, functional, or malignant and may require surgery. Therefore all require follow-up. This study aimed to determine the pattern of adrenal incidentaloma follow-up in a level 1 trauma center, focusing on the factors that influence whether follow-up is facilitated.

Body weight change is unpredictable after total thyroidectomy.

Background: There is a common perception that total thyroidectomy causes weight gain beyond expected age-related changes, even when thyroid replacement therapy induces a euthyroid state. The aim of this study was to determine whether patients who underwent total thyroidectomy for a wide spectrum of conditions experienced weight gain following surgery.

Methods: We retrospectively studied 107 consecutive total thyroidectomy patients treated between January 2013 and June 2014.

Total thyroidectomy for pressure symptoms in patients with Hashimoto's thyroiditis.

Background: Hashimoto's thyroiditis (HT) is rarely on its own the indication for thyroidectomy. However, surgery in patients with HT will be undertaken when there is malignancy and may be required for pressure symptoms. Therefore, this study aimed to investigate the indications for surgery in HT patients.
