Transoral endoscopic thyroidectomy vestibular approach as a novel technique for pediatric populations: Results from a single surgeon

Modified Radical Neck Dissection for Papillary Thyroid Carcinoma via a Combined Endoscopy Approach: The Transoral Approach and the Chest Approach

BACKGROUND

Recently, modified radical neck dissection (MRND) for papillary thyroid carcinoma (PTC) has been performed by the transoral endoscopic approach.1 However, dissection of level II lymph nodes using only the transoral approach is highly difficult because of the inadequate axis of surgical view. Hence, we decided to combine the transoral and chest approaches to perform MRND. To the best of our knowledge, this is the first video case of MRND using the combined approach.

PATIENT AND METHODS

A 35-year-old woman was diagnosed with cT1aN1bM0 right PTC (metastatic to right level III lymph nodes). The patient underwent total thyroidectomy, bilateral central neck dissection (CND), and right MRND via a combined endoscopic approach: the transoral and chest approaches. Total thyroidectomy and bilateral central neck dissection were performed via the transoral approach, similar to prior studies.2-6 The chest approach can help the surgeon to perform level II and the transoral approach was used to dissect the lymph node of levels III and IV.

RESULTS

The total time for total thyroidectomy, bilateral CND, and right MRND was 190 min. The time for MRND was 90 min. The number of harvested lymph nodes were 14 in the right lateral compartments, and the number of metastatic lymph nodes were 2 in the lateral compartments. There were no major postoperative complications. The patient was completely satisfied with the cosmetic result.

CONCLUSIONS

The combined approach of the transoral and chest approaches was sufficient to perform total thyroidectomy and MRND for levels II, III, and IV.

Thyroid diseases in children and adolescents requiring surgical treatment-indications, techniques, results, and complications based on 10 years of the single center's own experience

Introduction

Although thyroid abnormalities are observed less frequently in children than in adults, the increased incidence of thyroid cancer makes it mandatory for all pediatric surgeons to be knowledgeable about the disorders of this gland. Thyroid abnormalities can be associated with hyperthyroidism or hypothyroidism and euthyroidism and/or symmetric or asymmetric enlargement of the gland.

Aim

The present study was undertaken to retrospectively analyze the indications, surgical techniques used, results obtained, and complications found in the surgical treatment of thyroid diseases in children and adolescents in a surgical center for the macro-region of western Poland.

Methods

The data of 148 patients undergoing total or partial thyroidectomy between 2013 and 2022 were analyzed from the medical records of the Department of Pediatric Surgery, Traumatology, and Urology of the Medical University of Poznan, Poland.

Results

A total of 95 children underwent subtotal thyroidectomy and 64 underwent total thyroidectomy, of which the procedure was widened to include prophylactic removal of neck lymph nodes in 45 patients. There were 113 girls (76%) in the analyzed group, and the average age of the patients at the time of surgical treatment was 15 years. The average time from the diagnosis of thyroid disease to surgery was 4 months, ranging from 2 weeks to 3 years. Of the 64 patients undergoing total thyroid resection, 35 (54.69%) were diagnosed with thyroid cancer.

Conclusions

Collaboration within a multidisciplinary team ensures optimal surgical outcomes in children and adolescents with thyroid disease. With extreme caution, thyroid removal is a safe procedure with few complications, but the experience of the surgeon performing thyroid surgery in children remains crucial. Despite the absence of such a diagnosis in the first fine-needle aspiration biopsy, the high percentage of thyroid carcinomas in the analyzed group may be because the initial biopsy was performed in a less experienced center, also in terms of histopathological laboratory. Hence, we point out the necessity of performing a repeat fine-needle aspiration biopsy (according to the Bethesda classification) in a more experienced center before the final decision of thyroidectomy.
