About

The robot-assisted surgery for benign and malignant thyroid tumors was widely developed in Asia and begins to spread in Western countries. The main advantage of the technique is to avoid a scar in the neck by placing it either in the axilla or at the hairline behind the ear to improve esthetic consequences and body image. It is not surgery minimally invasive but rather a way of remote access surgery.

Data from the literature including cohort studies and meta-analyzes attest the security of the procedure in comparison with classic thyroid surgery (which remains the "gold standard"). However there is few data on the effectiveness of the technique in terms of the completeness of the surgery, according to the routine standard criteria used in endocrinology and endocrine cancer, and no French medico-economic study has been performed.

Inclusion criteria

1. Benign thyroid nodule or follicular or suspicious cytological (Bethesda classifications 2, 3, 4, or 5) requiring thyroid lobectomy or total thyroidectomy therapeutic or diagnostic
2. Differentiated thyroid cancers - CN0 (no suspicious lymph node in the central or lateral compartments on preoperative ultrasound - CN1A / b with lymph node metastases <or = 10 mm in areas VI, III and / or IV, detected on preoperative ultrasound - For which the indication of a lobectomy or total thyroidectomy, with or without dissection of the central compartment and / or lateral neck was put in multidisciplinary meeting

4. Patient general condition of WHO grade 0-1
5. Patient age > 18 years and able to comply with the protocol visits
6. Patient agreeing to undergo robot-assisted surgery, the incision being at patient choice, depending on the wishes concerning the location of the scar (Axillary or behind the ear channel)
