Background
The aim of this study was to compare conventional open thyroidectomy with robotic thyroidectomy in terms of postoperative pain.
Methods
We compared the intensity of postoperative pain experienced by patients who received conventional open thyroidectomy (n = 45) versus those who underwent robotic thyroidectomy (n = 45). During surgery, we carefully controlled the anesthetic conditions. All the patients underwent a total thyroidectomy with ipsilateral central compartment node dissection. Postoperative pain in the 2 groups was compared using a visual analog scale and the amount of rescue analgesic at 30 min, 4 h, 1, 2, 3, and 10 days after surgery.
Results
The postoperative pain at 30 min and 4 h after surgery were 3.0 ± 0.9 and 2.6 ± 0.9 (p = .066) and 4.9 ± 1.3 and 4.4 ± 1.3 (p = .055) in the conventional open group and the robotic group, respectively. The mean pain scores at 1, 2, 3, and 10 days after surgery were 3.8 ± 1.3 and 3.0 ± 1.3 (p = .001), 2.6 ± 1.2 and 2.0 ± 0.9 (p = .005), 1.7 ± 0.9 and 1.3 ± 0.6 (p = .034), and 0.9 ± 0.7 and 1.2 ± 1.1 (p = .093), respectively. No significant differences were observed between the 2 groups in terms of postoperative rescue analgesic use (1.1 ± 1.1 and 0.8 ± 0.9, p = .264).
Conclusions
Even though robotic thyroidectomy using the transaxillary technique requires a more extensive subcutaneous dissection than conventional open thyroidectomy, robotic thyroidectomy does not result in more postoperative pain or use of analgesic when compared with open thyroidectomy.
