Endoscopic Lateral Neck Dissection: A New Frontier in Endoscopic Thyroid Surgery

BackgroundEndoscopic thyroidectomy and robotic thyroidectomy are effective and safe surgical options for thyroid surgery, with excellent cosmetic outcomes. However, in regard to lateral neck dissection (LND), much effort is required to alleviate cervical disfigurement derived from a long incision. Technologic innovations have allowed for endoscopic LND, without the need for extended cervical incisions and providing access to remote sites, including axillary, chest–breast, face-lift, transoral, and hybrid approaches.MethodsA comprehensive review of published literature was performed using the search terms “lateral neck dissection”, “thyroid”, and “endoscopy OR endoscopic OR endoscope OR robotic” in PubMed.ResultsThis review provides an overview of the current knowledge regarding endoscopic LND, and it specifically addresses the following points: 1) the surgical procedure, 2) the indications and contraindications, 3) the complications and surgical outcomes, and 4) the technical advantages and limitations. Robotic LND, totally endoscopic LND, and endoscope-assisted LND are separately discussed.ConclusionsEndoscopic LND is a feasible and safe technique in terms of complete resection of the selected neck levels, complications, and cosmetic outcomes. However, it is recommended to strictly select criteria when expanding the population of eligible patients. A formal indication for endoscopic LND has not yet been established. Thus, a well-designed, multicenter study with a large cohort is necessary to confirm the feasibility, long-term outcomes, oncological safety, and influence of endoscopic LND on patient quality of life (QoL).

Ambulatory Endoscopic Thyroidectomy via a Chest-Breast Approach Has an Acceptable Safety Profile for Thyroid Nodule

IntroductionWith the growing esthetic requirements, endoscopic thyroidectomy develops rapidly and is widely accepted by practitioners and patients to avoid the neck scar caused by open thyroidectomy. Although ambulatory open thyroidectomy is adopted by multiple medical centers, the safety and potential of ambulatory endoscopic thyroidectomy via a chest-breast approach (ETCBA) is poorly investigated.Material and MethodsPatients with thyroid nodules who received conventional or ambulatory ETCBA at Xiangya hospital, Central South University from January 2017 to June 2020 were retrospectively included. The incidence of postoperative complications, 30-days readmission rate, financial cost, duration of hospitalization, mental health were mainly investigated.ResultsA total of 260 patients were included with 206 (79.2%) suffering from thyroid carcinoma, while 159 of 260 received ambulatory ETCBA. There was no statistically significant difference in the incidence of postoperative complications (P=0.249) or 30-days readmission rate (P=1.000). In addition, The mean economic cost of the ambulatory group had a 29.5% reduction compared with the conventional group (P<0.001). Meanwhile, the duration of hospitalization of the ambulatory group was also significantly shorter than the conventional group (P<0.001). Patients received ambulatory ETCBA showed a higher level of anxiety (P=0.041) and stress (P=0.016). Subgroup analyses showed consistent results among patients with thyroid cancer with a 12.9% higher complication incidence than the conventional ETCBA (P=0.068).ConclusionAmbulatory ETCBA is as safe as conventional ETCBA for selective patients with thyroid nodules or thyroid cancer, however with significant economic benefits and shorter duration of hospitalization. Extra attention should be paid to manage the anxiety and stress of patients who received ambulatory ETCBA.
