Clinical experience with modified Miccoli's endoscopic thyroidectomy for treatment of thyroid carcinoma in 86 cases

The main purpose of this study was to assess the feasibility and relevant applying techniques of total thyroidectomy for thyroid carcinoma with a modified Miccoli's approach.

Eighty-six patients with thyroid carcinoma consecutively received radical operation from October 2007 to June 2012. A cavity above the gland was constructed by a modified suspension method using the suspension retractor with suction catheter after the pathway making. Eighty-six cases underwent the modified Miccoli's endoscopic thyroidectomy using the ultrasonic scalpel and the space maintain-regulating device. Level VI lymph node dissection was performed using the method of inspection pit.

All the procedures were completed successfully. The average detection rate of level VI lymph nodes, the average time of thyroidectomy and lymph nodes dissection were 7.27 ± 3.99 pieces per case, 51.32 ± 13.35 min, and 38.43 ± 15.24 min, respectively. With regard to postoperative complications, there were three cases of delayed transient hoarseness, two patients with transient numbness of hands and feet, one subject with chylous fistula, and no hemorrhage.

Total thyroidectomy for thyroid carcinoma can be safely performed with the modified Miccoli's approach by using ultrasonic scalpel and the space maintain-regulating device. Application of these adaptive reforms can obviously reduce the difficulties in manipulation and have the advantages of minimal incisions, good cosmetic results, less bleeding, shorter hospital stay, and fewer complications.
