The LigaSure (LS) system did not significantly reduce operative time in thyroidectomy compared to conventional clips and ties (CLTs). While LS improved voice outcomes, it significantly increased costs, offering limited utility.
Area of Science:
- Surgical Innovation
- Thyroid Surgery Techniques
- Minimally Invasive Procedures
Background:
- Hemostasis is crucial in thyroid surgery, often prolonging operative time.
- The LigaSure (LS) system offers diathermy hemostasis by fusing vessel walls.
- Prior research suggested LS reduces thyroidectomy operative times.
Purpose of the Study:
- To compare operative times of the LS system versus conventional clips and ties (CLTs) in thyroidectomy.
- To evaluate secondary outcomes including vocal cord function, Voice Handicap Index (VHI) scores, hypocalcemia, and costs.
Main Methods:
- Twenty-eight patients undergoing thyroidectomy were randomized to either the LS system or CLTs.
- Data collected included patient demographics, operative times, VHI scores, vocal cord endoscopy, and operative costs.
- Postoperative monitoring for hypocalcemia was performed.
Main Results:
- Mean operative times were similar: 68.6 minutes (CLTs) vs. 68.5 minutes (LS), P > .05.
- Postoperative VHI scores were significantly lower with LS (6.57) compared to CLTs (19.83), P = .041.
- The LS system incurred significantly higher operative costs ($387.15) than CLTs ($73.60), P < .001.
Conclusions:
- The LigaSure system did not offer a clinically significant reduction in operative time for thyroidectomy.
- Despite improving voice handicap scores, the LS system's significantly higher cost limits its utility.
- Findings contradict previous literature suggesting reduced operative times with the LS system.
