Comparison of the vessel sealer Extend® with harmonic ACE® in robotic bilateral axillary-breast approach thyroid surgery

摘要

Background: Harmonic ACE (Harmonic) Curved Shears are frequently used for vessel sealing in patients undergoing robotic thyroidectomy. Unlike other robotic devices with articulation, the Harmonic device can only move in a straight-forward direction without articulation. The recently introduced Vessel Sealer Extend (VSE) provides bipolar sealing and cutting with articulation movement. This study compared the VSE and Harmonic devices in robotic bilateral axillary-breast approach (BABA) thyroid surgery. Methods: From December 2018 to March 2019, 35 consecutive patients underwent robotic BABA thyroidectomy, 20 using the VSE and 15 using the Harmonic device. Patient characteristics, pathologic results, and clinical outcomes, including complications, were evaluated. Results: The characteristics of patients in the two groups were similar. Surgical time from robot docking to completion of lobectomy was longer in the VSE than in the Harmonic group (45.009.52 vs. 39.7212.76 min; P=0.170). The number of camera cleanings during lobectomy was significantly lower in the VSE group (0.550.51 vs. 1.931.71; P=0.002). Intraoperative blood loss (53.0043.29 vs. 28.6741.03 mL; P=0.102), hospital stay after surgery (3.550.95 vs. 3.670.90 days; P=0.715), and pain scores on the first (2.850.37 vs. 2.930.26; P=0.458) and second (2.550.51 vs. 2.600.51; P=0.775) postoperative days were similar in the VSE and Harmonic groups. No patient experienced vocal cord palsy or postoperative bleeding.
