Endoscopic Thyroidectomy in Anterior Chest Approach Versus Open Thyroidectomy for Patients with Papillary Thyroid Carcinomas, a Retrospective Study.

Background: To compare the endoscopic thyroidectomy (ET) with the open thyroidectomy (OT) for patients with papillary thyroid carcinomas and share our experience of central lymph nodes dissection and recurrent laryngeal nerve exposure. Materials and Methods: From January 2015 to July 2017, 197 patients were enrolled in our hospital. Among them, 85 underwent ET and 112 underwent OT. The mean age of the patients was 38.15 ± 11.72 years in ET group and 47.79 ± 10.51 years in OT group. Unilateral thyroidectomy was performed in 47 patients of ET group and 63 patients of OT group. Bilateral thyroidectomy was performed in 38 patients of ET group and 49 patients of OT group. Intraoperative information, including operation time, hemorrhage, tumor size, capsular invasion, central LN metastasis, number of retrieved lymph nodes, hospital stay, cost, postoperative complication, and cosmetic satisfaction, was compared between the two groups. Results: The operation time of ET group was significantly longer (P < .05). There were no significant differences between the two groups in postoperative complications (P > .05). The patients in ET group were more satisfied with the cosmetic effects (P < .05). Conclusion: ET was a safe and effective alternative operation method for selected patients with papillary thyroid carcinomas.
