Application value of non-inflating endoscopic instrument in endoscopic thyroid surgery through the whole areola approach

ObjectiveTo investigate the feasibility and safety of the design of the internal support apparatus in endoscopic thyroid surgery via whole areola approach.

MethodsThe clinical data of 20 patients with thyroid tumor were retrospectively analyzed.The patients were treated with non-inflatable areola approach endoscopic thyroidectomy using modified cavity construction instrument, and the relevant clinical indicators were analyzed.

ResultsTwenty patients were successfully operated, and not be transfered.The results of postoperative pathology showed that 18 cases were minimal papillary carcinoma of thyroid, and 2 cases were benign thyroid nodules.The unilateral lobotomy was performed in 2 cases, the unilateral glandular leaf + isthmus + central area were cleared in 16 cases, and the bilateral lateral glandular leaves + isthmus + central area were cleared in 2 cases.The operation time was (120.50±40.62) min, the number of central lymph nodes dissected was (6.32±3.00), and the postoperative extubation time was (3.68±2.34) days.One case with recurrent laryngeal nerve palsy after operation was found.The postoperative puncture tunnel bleeding in 1 case was stopped after local pressure dressing.The postoperative hypocalcium convulsions in 1 case was relieved 3 days later.The surgical satisfaction was(8.28±1.42) point.

ConclusionsThe internal support free air-filling endoscope in assisting thyroid surgery is feasible, similar to that of CO₂ and simple to operate.It can reduce medical cost and anesthesia risk, which is worthy of further exploration.
