[Endoscopic thyroidectomy via median approach with gas insufflation: analysis of the first 100 cases]. / Thyroïdectomie endoscopique par une approche médiane avec insufflation gazeuse: analyse des 100 premiers patients.

OBJECTIVE: To report the initial experience with videoscopic thyroidectomy using a cervical approach with median placement of the optical trocar and gas insufflation. PATIENTS AND METHODS: Retrospective study of the first 100 consecutive patients. RESULTS: Seven isthmectomies, 86 lobectomies, and 7 total thyroidectomies were performed. Parathyroidectomy for hyperparathyroidism was also performed in 3 patients. Mean operative time was 77 minutes. No post-operative subcutaneous emphysema was noted. Conversion to open surgery occurred in 10% of cases but the conversion rate decreased to 2.6% when the harmonic scalpel became available. Post-operative complications included one transient recurrent laryngeal nerve palsy. There were no hematomas and no hypocalcemia. The mean post-operative pain scale was 2.7 (on a visual scale of 1-10). Mean hospital stay was 1.5 days. The cosmetic result was considered excellent. CONCLUSIONS: Endoscopic total thyroidectomy aided by gas insufflation is technically feasible. The harmonic scalpel aids greatly in dissection and hemostasis. It is a valid option in the surgical management of thyroid disease but careful pre-operative selection of patients is mandatory.
