Abstract:
Objective To compare the value of 980 nm diode laser with holmium: YAG laser in central airway ablation therapy. Methods Fifty-eight consecutive patients who underwent tracheobronchial laser ablation in the department of thoracic surgery of Nankai hospital between September 1st , 2020 and September 30th, 2022 were randomly grouped and treated with 980 nm diode laser and holmium: YAG laser respectively. The differences of smoke size, brightness field visibility, bleeding, hemostatic effect, postoperative granulation, ablation time and safety were compared between the two groups. Results The brightness of the field in the 980 nm diode laser group had a greater impact on the operation (P<0.001), and there were no significant differences between two groups in terms of smoke size (P=0.81), bleeding (P=0.46), hemostatic effect (P=0.41), postoperative granulomatous proliferation (P=1.00), ablation efficiency (P=0.62) and safety. Conclusion Compared with holmium: YAG laser, 980 nm diode laser has similar therapeutic effect, and it has advantages of small size, good economy and no restriction of power supply, so it can be used as an alternative choice for holmium laser.
