Implications anesthésiques de la chirurgie thyroïdienne ou parathyroïdienne par voie axillaire sous robot-assistance : à propos de sept premiers cas

Anesthetic implications for robot-assisted transaxillary thyroid and parathyroid surgery: a report of twenty cases

Gasless transaxillary robot-assisted endoscopic thyroid surgery has recently been proposed and developed in South Korea and the United States. Perianesthetic implications and their evolution for 20 patients scheduled to undergo this innovative surgical technique are presented. The anesthetic considerations focus on the length of surgery due to the learning curve, the risk of the ipsilateral arm posture, and postoperative pain evaluation and management.

Indications for the gasless transaxillary robotic approach to thyroid surgery: experience of forty-seven procedures at the american hospital of paris

BACKGROUND

Thyroid surgery is in a state of evolution from traditional open approaches to novel robotic techniques. The gasless transaxillary approach to thyroid surgery is effective in the management of thyroid cancer, and complications after robotic thyroidectomy are no higher than experienced after open or endoscopic techniques. The transaxillary robotic approach also avoids an anterior neck scar. This paper presents what the authors believe to be the largest cohort of patients reported in Europe undergoing gasless transaxillary robotic thyroid surgery, with the aim of defining the indications for this procedure.

METHODS

Forty-six patients underwent robotic thyroid surgery via the transaxillary approach and were enrolled in this study between March 2010 and September 2012. All patients were operated on by one surgeon at one clinical center. Reviewed data included patient characteristics, pathological characteristics, extent of surgery and postoperative complications. The mean follow-up time was 7.29 months.

RESULTS

Forty-six patients underwent 47 procedures, the average age of the patients was 43 years and the male to female ratio was 1:22. Undertaken were 30 lobectomies, 3 subtotal thyroidectomies, 13 total thyroidectomies and 1 totalization. One case was converted to an open procedure. The ratio of malignant to benign disease was 1:6.67 (6:40 cases) and analysis of the surgical specimens showed 6 follicular lesions, 24 follicular adenomas, 3 colloid lesions, 1 case of thyroiditis/lymphatic lesion, 3 adenomatoid lesions, 3 oncocytic adenomas, 3 papillary cancers and 3 microcapillary cancers. The overall average size of an individual specimen removed was 45.40 ± 28.95 cm(3) (range 5-160, n = 47) and the average largest diameter of the lesion removed was 3.72 ± 0.95 cm (range 1.4-6.0, n = 47). Postoperatively, there were 5 recurrent laryngeal nerve injuries (4 transient), 2 transient brachial plexopathies, 1 case of postoperative dysphagia and 1 of collection of blood at the site of surgery. There were no cases of disease recurrence at follow-up.

CONCLUSIONS

The gasless robotic transaxillary approach to thyroid surgery has been predicted to become a standard technique. It has been shown to be efficacious in the management of thyroid cancer with lateral neck metastases; however, more data relating to oncological safety in long-term follow-up is required. This intervention is also appropriate for benign thyroid disease including Graves' disease. To achieve consistently successful results, careful patient selection is fundamental in terms of patient characteristics and the anatomical aspects of the lesion. This is especially important with a geographical expansion to include North America and Europe. The excellent cosmetic results of this procedure make it ideal for patients who have esthetic concerns regarding particular difficulties with healing; however, in common with all new surgical procedures, further evidence must be sought to confirm its indications over time.

Operative outcomes of robot-assisted transaxillary thyroid surgery for benign thyroid disease: early experience in 50 patients

PURPOSE

The main benefits of robot-assisted transaxillary thyroid surgery are to overcome the technical limitations of other endoscopic procedures for this surgical pathology and to avoid any cervical skin incision. This article describes the first experience of a Romanian team with the endoscopic robot-assisted thyroid surgery.

MATERIAL AND METHODS

We used the da Vinci SI intuitive surgical system to carry out 50 thyroid operations: 33 unilateral total lobectomies with isthmectomy (TL), 8 unilateral total lobectomies, with contralateral subtotal lobectomy, and 9 total thyroidectomies. Preoperatively, the patients were diagnosed with nodular goiter in 42 cases, nodular autoimmune thyroiditis in 3 cases, Basedow disease in 2 cases, toxic thyroid adenoma in 2 cases, and diffuse goiter in 1 case. We analyzed the clinical characteristics, size and location of the nodules, surgery duration, postoperative complications, pain medication, histopathological findings and postoperative cosmetic results.

RESULTS

All surgical procedures were carried out without major incidents. One case required conversion to open approach. The mean length of surgery was 159 ± 38.2 min and the average console time was 68 ± 39.9 min; postoperatively, we recorded one case of transient brachial plexus neurapraxia, one transient vocal cord paresis, one transient hypocalcemia, and four postoperative wound complications. The final histopathological examination revealed two cases of well-differentiated carcinoma.

CONCLUSIONS

This paper reports the largest series to date in Southeast Europe about robot-assisted transaxillary thyroidectomy. On a group of selected Caucasian patients, postoperative results were similar to open cervicotomy in terms of postoperative complications. The major cosmetic advantage is the absence of scar in the anterior cervical region.
