Robot‐assisted transaxillary surgery for thyroid cancer: Oncologic and surgical outcomes in long term follow‐up

Abstract

BACKGROUND: The use of robot-assisted transaxillary thyroidectomy (RATT) has rapidly spread in the last 2 decades, although it is mostly limited to Asian countries. METHOD: We retrospectively enroled all patients with histologic diagnoses of thyroid cancer who underwent RATT at the University Hospital of Pisa from May 2012 to September 2020. RESULTS: The study included 242 patients; 128 (47%) underwent total thyroidectomy and 114 (53%) underwent thyroid lobectomy, among which 28 patients (24.6%) required completion thyroidectomy. Radioactive iodine ablation therapy was required in 90 patients (37%). The complication rate was 5.3%. After a median follow-up of 38 months, an excellent response to therapy was achieved in 107 patients (74%), whereas the response was indeterminate in 12 (8%) and incomplete in 16 (11%). No local or distant relapses or increases in thyroglobulin or antibody levels were documented. CONCLUSIONS: In experienced hands, RATT represents a valid option for the treatment of thyroid cancer in selected cases.
