Initial Experience With a Gasless Unilateral Axillo-Breast or Axillary Approach Endoscopic Thyroidectomy for Papillary Thyroid Microcarcinoma: Comparison With Conventional Open Thyroidectomy

Abstract

The efficacy of various endoscopic thyroidectomy has not been determined for papillary thyroid microcarcinoma (PTMC). We compared 31 consecutive patients with PTMC who underwent endoscopic thyroidectomy by a gasless unilateral axillo-breast or axillary approach, and the 36 PTMC patients who underwent conventional open thyroid lobectomy from August 2005 to December 2008. There were more female patients (P = 0.004) in the endoscopic group, and the mean age of endoscopic group was younger than that of the open thyroidectomy group (P = 0.006). The entire endoscopic thyroidectomy was successfully completed in all the patients. The operative time was longer for those undergoing endoscopic thyroidectomy (P < 0.001). The complication rate did not differ between the 2 groups. The cosmetic satisfaction, as evaluated by questionnaire, was greater in the endoscopic group (P < 0.001). Endoscopic thyroidectomy by a gasless unilateral axillo-breast or axillary approach for selected cases of PTMC is a feasible, safe, and cosmetically superior procedure.
