Gasless single incision endoscopic thyroidectomy.
BACKGROUND
Endoscopic thyroidectomy making the scar outside the neck area has a cosmetic appeal for patients. Based on an anterior chest wall approach combined with the gasless technique, we developed a novel method for gasless endoscopic thyroidectomy with a single incision.


METHODS
From March 2009 to November 2010, 48 patients with benign thyroid nodules underwent thyroidectomy with the gasless single-incision endoscopic surgery technique via the anterior chest wall approach. A 3-cm long skin incision parallel to the clavicle was made on  the anterior chest wall on the side of the lesion. The platysma flap was lifted up to maintain working space from the incision to the thyroid cartilage. Dissection of the thyroid was begun from the inferior pole of the thyroid. The line of resection was selected to preserve recurrent laryngeal  nerve and parathyroids. A 5-mm drainage tube was inserted into the lower portion of the operative space through the incision after the thyroid gland and the lesion were resected using the Harmonic scalpel.


RESULTS
The overall operating time was 126 minutes (range, 90 to 210), 138  minutes (range, 80 to 160) in first 24 cases; and 112 minutes in the second 24 patients (P<.05). Three cases were converted to the conventional procedure: 2 because of a malignancy diagnosed on frozen section, and one due to uncontrolled bleeding from the middle thyroid vein. Another malignancy  diagnosed on final pathological examination was treated with additional surgery to complete the thyroidectomy by using the conventional open method. There were 2 cases of postoperative complications: transient hoarseness and hematoma. No wound infection occurred in our series. The scar was  well hidden beneath the clothes, and the patients were satisfied with the cosmetic result of the surgery.


CONCLUSIONS
Advantages of the chest wall approach combined with the gasless technique have made singleincision endoscopic thyroidectomy more feasible and practicable.
