Endoscopic Thyroidectomy for Large-Sized Goiters: Merits of the Axillo-Breast Approach with Gas Insufflation.

Background: Several minimal access approaches to the thyroid gland have been widely applied; nevertheless, such approaches are still challenging when dealing with large-sized thyroid nodules or goiters. We hereby evaluated the outcomes and highlighted the merits of endoscopic axillo-breast hemithyroidectomy (EABH) for large-sized unilateral goiters.

Methods: Patients underwent EABH for unilateral large thyroid nodules ≥6 cm in its greatest dimension or unilateral large goiter (≥60 ml sonographic volume) whatever the size of its contained nodules were identified from a prospectively maintained database. Their demographic data, clinicopathological profiles, and surgical and esthetic outcomes are reported and analyzed.

Results: Over a 2-year period, 33 patients matched the selection criteria. Their mean age was 34.75 ± 11.39 years. There were 30 women and 3 men. The majority of nodules were radiologically TIRADS3 and cytologically Bethesda 3. The mean sonographic dominant nodule greatest dimension was 5.29 ± 1.48 cm (range: 3-9.5 cm). The mean sonographic volume of the pathological lobe was 101.86 ± 54.45 ml (range: 60.11-236.88 ml). All cases were completed endoscopically with no conversion to open. The mean operative time was 110.76 ± 18.75 minutes. No significant postoperative complications were reported except for one case with temporary vocal cord paresis. Most (87.9%) of the patients were extremely satisfied with the procedure.

Conclusion: EABH with our suggested key steps could be considered an effective valid approach for unilateral large goiters in trained hands and in patients desirous for cosmesis.
