Article
A minimal access procedure does not necessarily mean that it is minimally invasive. However, as its name implies, MIVAT is a truly minimally invasive treatment modality. The advantages it offers over its conventional counterpart are indeed related to its minimally invasive nature. Furthermore, this nature has not compromised its ability to accompli...
Article
Background: Robot-assisted transaxillary thyroid surgery, widely accepted and used in Eastern countries, can be an appealing treatment option for both patients with major concerns regarding a cervical scar, and their surgeons. Patients are offered a scarless neck surgery, while their surgeons are offered improved dexterity and ergonomics compared...
Article
Background: Patients labeled as having indeterminate thyroid nodular disease following fine needle aspiration cytology are at risk of non-optimal initial surgery: an overly radical total thyroidectomy, or an unnecessary two stage operation. The objective of this study was to assess the impact of combining mutational markers and ultrasonographic fe...
Article
Purpose: The extent of surgery for pediatric papillary thyroid carcinoma is debatable. The aim of this study was to evaluate the feasibility of offering pediatric patients a tailored surgical approach based on certain clinical features. Methods: A national multicenter retrospective review of 250 pediatric patients treated for papillary thyroid c...
Article
Full-text available
Papillary thyroid carcinomas are favorable prognosis cancers. Most patients have an excellent long term overall survival rate. As a result, disease-free survival has replaced overall survival as the main outcome of interest when effective initial management of these tumors is considered. The role of prophylactic central neck dissection represents a...

This mini-review provides an update on the challenges and controversies surrounding levothyroxine therapy in thyroidectomized patients, following an extensive review on dosing strategies and available formulations. Despite efforts to establish an ideal dosage adjustment method, achieving optimal thyroid hormone replacement remains complex due to in...
Article
Background Thyroid surgery in the pediatric population is highly challenging due to the high frequency of hypoparathyroidism, especially in cases where central compartment emptying is required. When permanent quality of life is reduced and overall morbidity and mortality increased. NIRAF + ICG is used currently to decrease the risk of post-operativ...
Article
Background Parathyroid adenoma intraoperative localization can be challenging. PTeye™ and FLUOBEAM® LX assist to real-time intraoperative identification of parathyroid glands. Both devices use autofluorescence to confirm visually suspected parathyroid tissue. The aim of the present study is to evaluate and compare the efficacy of PTeye™ and FLUOBEA...
Article
Full-text available
Parathyroid adenoma is the main cause of primary hyperparathyroidism. The genetic basis of the disease is still unclear. Vitamin D receptor (VDR) is involved in parathormone regulation. The aim of this study is to evaluate Vitamin D receptor expression in sporadic parathyroid adenoma. Fifty-one patients with parathyroid adenoma and 51 healthy volun...
Article
Full-text available
Background The role of near-infrared autofluorescence (NIRAF)-imaging in thyroid surgery is well-established. However, its role in hyperparathyroidism surgery is yet to be defined due to the lack of consensus regarding the autofluorescence (AF) pattern of parathyroid adenomas (PAs). Furthermore, its utility in minimally invasive video-assisted para...
Article

Background Disease-free survival is the main outcome of interest considered when assessing the effectiveness of surgical management of papillary thyroid carcinoma (PTC). Specific characteristics of nodal metastases have been demonstrated to impact the risk of recurrence. Objective Verify the oncologic rationale of prophylactic central compartment...
Article
Hypoparathyroidism is the most common complication of thyroid surgery. The best way to assume normal parathyroid gland (PTG) function is to preserve them in situ, undamaged. Near-infrared autofluorescence (NIRAF)-imaging has been introduced as a potentially useful adjunct in thyroid surgery. To assess the surgical outcomes of NIRAF-imaging utility...
Article
The unprecedented technical and technological evolution in thyroid surgery has labelled it as an extremely safe and efficient procedure, and indeed “typifies perhaps better than any other operation the supreme triumph of the surgeon’s art.”—William Halsted, 1852–1922. Surgeon’s experience reflected by annual case load is the most important denomina...

The aim of this study is to determine a correlation between the degree of neck hyperextension on the operative table and...
Article
Full-text available
Background and Objectives: Parathyroid adenoma is a distinct cause of primary hyperparathyroidism, with the vast majority being sporadic ones. Proteomic analysis of parathyroid adenomas has proposed a large number of related proteins. The aim of this study is to evaluate the immunohistochemical staining of ANXA2, MED12, MAPK1 and VDR in parathyroid...
Article

This review aims to evaluate the surgical management of thyroid disease in patients under 18 years old. Methods We conducted a bibliographic search in the international literature. Data from...
Article
Introduction Post‐surgical hypoparathyroidism often occurs after total thyroidectomy (TT). The aim of this study is to investigate whether the use of near‐infrared autofluorescence (NIRAF) of parathyroid glands (PGs) can aid experienced surgeons in identifying more PGs during surgery, potentially reducing unintended resection, and assessing its imp...
Article
Background Parathyroid adenoma is the most common cause of primary hyperparathyroidism. It is characterized by hypersecretion of parathormone and elevated serum concentration of ionized calcium. Patient preoperative information is of great importance and should include the explanation of hyperparathyroidism pathophysiology and clinical characterist...

Elective cesarean delivery is increasing worldwide; one reason is to protect against pelvic floor disorders, including urine incontinence. Previous studies included small sam...
Article
Full-text available
There is a high prevalence rate of peripheral artery disease worldwide, with estimated cases exceeding 200 million. Most patients are under-diagnosed and under-treated, and there is a lack of knowledge regarding the best therapeutic regimen and therapy duration, which leads to many cases of recurrence, complications, and amputations. This study aim...

Purpose Recent clinical practice guidelines consider thyroid lobectomy a viable alternative for low-risk papillary thyroid carcinoma PTC measuring 1–4 cm in size. We aimed to assess the likelihood of finding postoperatively determined high-risk histopathologic features that would lead to the recommendation of completion thyroidectomy. Methods A re...
Article
Introduction L’hypoparathyroïdie postopératoire survient dans 15–30 % après thyroïdectomie totale, restant définitive jusqu’à 7 %. Elle peut être sévèrement symptomatique, entraînant une hospitalisation prolongée ou une réadmission à l’hôpital. Une technique chirurgicale standardisée permet de réduire le taux postopératoire d’hypoparathyroïdie. Néa...
