Abstract
Background: Surgical plumes in small cavities, such as transoral endoscopic thyroid surgery, have never been satisfactorily resolved. We aimed to study the use of a smoke evacuation system and evaluate its efficacy, including the field of view and operating time.
Study design: We retrospectively reviewed 327 consecutive patients who underwent endoscopic thyroidectomy. They were separated into 2 groups based on whether the smoke evacuation system was used. To reduce the possible experience bias, only patients 4 months before and after implementing the evacuation system were included. Recorded endoscopic videos were evaluated, including the field of view, the incidence of scope clearance, and time spent during air-pocket creation.
Results: Overall, there were 64 patients with a median age of 43.59 years and a median body mass index of 22.87 kg/m2, including 54 women, 21 thyroid cancers, and 61 hemithyroidectomies. The operative duration was comparable between the groups. The group where the evacuation system was used scored more as good in terms of endoscopic views (8/32, 25% vs 1/32, 3.13%, P = .01), fewer incidences of endoscope lens pull out for clearance (3.5 vs 6.0 times, P < .01), less time for clear view after energy device activation (2.67 vs 5.00 seconds, P < .01), and less time spent (8.67 vs 12.38 minutes, P < .01) during air-pocket creation.
Conclusion: In conjunction with the synergy function of energy devices, evacuators enhance the field of view and optimize the time spent in the real clinical setting of low-pressure and small-space endoscopic thyroid procedures, in addition to the benefit of reducing smoke harm.
