气管肿瘤早期不易确诊,晚期患者往往伴有严重梗阻性呼吸困难,由于紧急的手术或放射治疗,每使病人有窒息的危险。此外,放疗后局部复发的气管癌患者,多不适于再度放疗。对以上两类患者,最近通过光导内窥镜行YAG 激光切除肿瘤术,获得令人鼓舞的效果。 Tracheal tumors are not easily diagnosed in the early stages. Patients with advanced disease are often accompanied by severe obstructive dyspnea. Each patient is at risk of asphyxiation due to urgent surgery or radiation therapy. In addition, local recurrence of tracheal cancer patients after radiotherapy is not suitable for re-radiotherapy. For the above two types of patients, recent YAG laser ablation of tumors with light-guided endoscopy has yielded encouraging results.
