Careful surgical technique for in situ preservation of parathyroid gland and autotransplantation of inadvertently removed parathyroid gland are important, especially in case of gross extrathyroidal extension. Adequate surgical experience is also an important factor. And routine bilateral central lymph node dissection should be done thoughtfully for its effect on postoperative hypoparathyroidism.

The outcomes of the patients with more advanced thyroid cancer who were treated with robotic thyroidectomy were comparable to those of the early cancer group patients. Well-designed investigations that are conducted at multiple centers are needed to affirm the validity of expanding indications of robotic thyroidectomy.

PurposeA number of researchers have suggested the use of sodium hyaluronate carboxymethyl cellulose (HA-CMC) membrane for preventing postoperative adhesion. This study evaluated the antiadhesive effect and safety of HA-CMC membrane in thyroidectomy for papillary thyroid cancer.MethodsOne hundred sixty-two patients who underwent thyroidectomy were prospectively randomized. In the study group of 80 patients, the 7.5 cm × 13 cm HA-CMC membrane was applied to the operative field after thyroidectomy. The subjects were asked about complications including adhesive symptoms using an 8-item questionnaire at 2 weeks, 3 months, and 6 months after surgery. In addition, items on the appearance of neck wrinkles and scars were evaluated by a physician who had no information about the patient's allocation.ResultsThere were no significant differences in complications such as swallowing difficulty, and wrinkles between study and control groups. Both groups presented significantly decreased scores over time in swallowing difficulty, and wrinkles. There were no complications regarding the HA-CMC membrane.ConclusionThe antiadhesive effect of HA-CMC membrane in thyroid surgery is still uncertain, although it is biologically safe. Further investigation is needed to confirm the antiadhesive effect of HA-CMC membrane in thyroid surgery.

Our study results show that outcomes of robotic thyroidectomy may be similar to that of conventional thyroidectomy, with possible better preservation of the parathyroid blood supply.
