Endoscopic Thyroidectomy for Solitary Thyroid Nodules

Abstract

Conventional thyroidectomy often leaves an undesirable scar on the anterior neck. The aim of this study was to assess the feasibility and efficacy of endoscopic thyroidectomy, a new minimally invasive technique for thyroid surgery. Between September 1998 and February 2000, 18 patients with a solitary thyroid nodule underwent endoscopic thyroidectomy utilizing CO₂ insufflation. There were 16 females and 2 males with a mean age of 43 years (range 17-66 years). Indications for surgery included indeterminate cytology (n = 8), follicular neoplasm (n = 8), Hürthle cell neoplasm (n= 1), and toxic thyroid nodule (n = 1). The mean nodule diameter was 2.7 cm (0.6-7 cm). Analgesic requirement, return to normal activity, and cosmetic results were compared to 18 consecutive patients who had conventional thyroidectomy. Sixteen of 18 cases were successfully completed endoscopically with a mean operating time of 220 minutes (range, 120-330 minutes). There were no major complications, but 3 patients developed mild hypercarbia and 1 patient had an incidental parathyroidectomy. When compared to conventional thyroidectomy, patients undergoing endoscopic thyroidectomy had a significantly superior cosmetic result (p < 0.005) and a quicker return to normal activity (p < 0.05), but there was no difference in analgesic requirement. Endoscopic thyroidectomy is a technically feasible and safe procedure that leads to an improved cosmetic result and a quicker recovery. Open completion thyroidectomy is recommended for thyroid carcinoma until more data are available.
