Comparison of conventional thyroidectomy and endoscopic thyroidectomy via axillo-bilateral breast approach in papillary thyroid carcinoma patients.

Abstract

Endoscopic thyroidectomy has been applied to solve the cosmetic problems that resulted from conventional thyroidectomy. The aim of this study was to evaluate and compare the surgical outcomes of conventional and endoscopic thyroidectomies via axillo-bilateral-breast approach (ABBA) in patients with papillary thyroid carcinoma (PTC). Between May 2007 and February 2011, 1003 patients with PTC underwent thyroidectomies. The eight hundred and thirty patients underwent conventional thyroidectomy and 173 patients underwent endoscopic thyroidectomy via ABBA. Clinicopathologic characteristics, complications, and surgical completeness were analyzed. The mean age was 49.53years who received a conventional thyroidectomy and 38.90years in endoscopic thyroidectomy (P<0.0001). The conventional thyroidectomy group underwent more extensive surgery than the endoscopic thyroidectomy group but the operation time was longer in the endoscopic thyroidectomy group (P<0.0001). The mean hospitalization length was 6.98days following open thyroidectomy and 6.40days after endoscopic thyroidectomy (P=0.003). The tumor size was larger in the conventional thyroidectomy group than the endoscopic thyroidectomy group and a lesser number of lymph nodes were retrieved in the endoscopic thyroidectomy group compared to the conventional thyroidectomy group (P<0.0001). The postoperative complications and thyroglobulin levels in both groups were not significantly different. These results suggest that conventional and endoscopic thyroidectomy via ABBA has similar surgical outcomes in PTC patients. Therefore, endoscopic thyroidectomy via ABBA may be an appropriate surgical alternative to conventional thyroidectomy for treating PTC in selected patients.
