Background
One of the advocated benefits of minimally invasive video-assisted thyroidectomy (MIVAT) is reduction of postoperative pain. We compared in a prospective study pain after video-assisted and conventional thyroidectomy (CT).
Methods
One hundred sixty-nine patients (56 men, 113 women, mean age: 50 ± 14 years) operated between November 2007 and February 2008 were included. MIVAT was performed if thyroid volume was <30 ml or the nodule diameter < 35 mm. Postoperative pain scores were documented on a visual analog scale (VAS; 0 = no and 100 = unbearable pain) at 8, 24, 36, and 48 h after surgery. Additionally, postoperative analgesic consumption was registered.
Results
Seventy-five patients (17 men, 58 women, mean age: 45 ± 15 years) underwent MIVAT and 94 (39 men, 55 women, mean age: 54 ± 15 years) CT. The mean overall VAS score at 8, 24, 36 and 48 h did not significantly differ between the groups (26 ± 21 vs. 26 ± 19 at 8 h, 17 ± 15 vs. 21 ± 18 at 24 h, 11 ± 13 vs. 10 ± 11 at 36 h and 7 ± 12 vs. 6 ± 8 at 48 h in MIVAT and CT group, respectively) [p = ns]. Twelve vs. 13 patients (16% vs. 14%) required opioid administration on the day of the operation [p = ns].
Conclusions
The length of the skin incision seems not to influence the perception of pain after thyroid surgery.
