Abstract
Purpose. The purpose of this study was to explore the feasibility of left central lymph node dissection (CLND) in endoscopic thyroidectomy via chest-breast approach (ETCB). Methods. Retrospective analysis of 57 cases of left CLND (group A) via ETCB, 35 cases of open left CLND (group B), and 90 cases of right CLND via ETCB (Group C) were performed from October 2014 to October 2019. Surgical data, complications, and follow-up data were compared among group A and group B, group A and group C, respectively. Results. There were no significant differences between group A and group B in intraoperative blood loss, tumor size, lymph node (LN) metastasis rate, dissected LN number, metastatic LN number, serum thyroglobulin (sTg), radioactive iodine uptake (RAIU), radioactive technetium uptake (RATU), radionuclide imaging of the residual area (RITRA), and radionuclide imaging of suspicious lymph node metastasis (RISLNM). There were no significant differences between group A and group C in age, operation time, intraoperative blood loss, postoperative hospital stay, tumor size, LN metastasis rate, dissected LN number, metastatic LN number, hypoparathyroidism, sTg, RAIU, RATU, RITRA, and RISLNM. There were 5 cases of temporary recurrent laryngeal nerve (RLN) palsy and 1 case of recurrence in group C. Besides, 1 case of lymphatic leakage was in group A. Conclusion. For selected cases, endoscopic left CLND is safe, feasible, efficient, and more easier than endoscopic right CLND.
