Abstract
BACKGROUND: Natural orifice transluminal endoscopic surgery has been adopted for thyroid surgery because of its potential for scar-free operation. However, the previous technique still has some limitations. Thus, we present our initial experience in transoral endoscopic thyroidectomy vestibular approach (TOETVA). METHODS: From April 2014 to January 2015, we used a three-port technique through the oral vestibule, one 10-mm port for laparoscope and two additional 5-mm ports for instruments. The CO2 insufflation pressure was set at 6 mm Hg. An anterior cervical subplatysmal space was created from the oral vestibule down to the sternal notch. The thyroidectomy was done endoscopically using conventional laparoscopic instruments and an ultrasonic device. RESULTS: A series of 60 procedures were accomplished successfully. 42 patients had single-thyroid nodules, and a lobectomy was performed. 22 patients had multinodular goiters and two patients had Graves' disease, with total thyroidectomy or Hartley-Dunhill procedures performed. Two had papillary thyroid carcinoma, and total thyroidectomy with central node dissection was performed. The median operative time was 115.5 min (range 75-300 min). The median blood loss was 30 mL (range 8-130 mL). Two patients experienced a transient hoarseness, which was resolved within 2 months. One patient experienced a late postoperative hematoma, which was treated conservatively. No mental nerve injury or infections were found. The patients were discharged in an average of 3.6 days (range 2-7 days) postoperatively. CONCLUSION: TOETVA is safe and feasible, resulting in no visible scarring. This technique may provide a method for ideal cosmetic results.
