国际性激光实验治疗中心的几个研究单位,以800多名患者为对象,对不能切除的恶性呼吸道阻塞病人,进行激光手术的实验性治疗。这种疾病一旦发展,肿瘤就与气管和支气管互相粘连,而且瘤体容易出血,所以手术条件难以确定。因这类患者没有其他疗法,最终多半死于窒息。使用Na-YAG激光能够烧割多余组织,而不损伤 International laser experimental treatment center of several research units to more than 800 patients for the treatment of unresectable malignant airway obstruction patients, the experimental treatment of laser surgery. Once the disease develops, the tumor and the trachea and bronchus adhesion to each other, and the tumor is easy to bleed, so the surgical conditions difficult to determine. Because these patients have no other treatment, they eventually die of suffocation. Using Na-YAG laser can burn excess tissue without damage
