Robotic-assisted modified radical neck dissection using a bilateral axillo-breast approach (robotic BABA MRND) for papillary thyroid carcinoma with lateral lymph node metastasis

Abstract

Background

Although safe in patients with papillary thyroid carcinoma (PTC), robotic thyroidectomy using a bilateral axillo-breast approach (BABA) has not been frequently performed in patients with advanced PTC. This study describes surgical outcomes in patients with PTC and lymph node metastasis (LNM) in lateral neck compartment who underwent robotic-assisted modified radical neck dissection with BABA (robotic BABA MRND).

Methods

The medical records of patients with PTC and lateral LNM who underwent robotic BABA MRND from March 2010 to July 2016 were retrospectively reviewed.

Results

Fifteen patients, 14 women and 1 man, of mean age 37.1 ± 9.3 years, were enrolled. Mean operation time was 272.7 ± 33.8 min. A mean 20.7 ± 7.2 lymph nodes were retrieved from the lateral neck compartment, with a mean 5.3 ± 4.4 lymph nodes being metastatic. The rates of transient and permanent hypocalcemia were 46.7 and 0%, respectively, and the rates of transient and permanent vocal cord palsy were 6.7 and 0%, respectively. Fourteen patients (93.3%) had stimulated thyroglobulin concentrations below 2 ng/mL after the first treatment with radioactive iodine.

Conclusions

Robotic BABA MRND could be safely performed and may be a good surgical option in selected patients with PTC and lateral LNM.
