我院自1990年以来,以Nd:YAG激光经内镜对不能手术或已经转移的食管癌病人27例进行姑息治疗,取得明显疗效,现报告如下: 资料方法本组27例中男21例、女6例,年龄61～78岁,术前均经X线、内镜检查及病理活检确诊鳞状细胞癌居多,其中上段2例,中段14例,下段11例。采用JCW—ⅡB型Nd:YAG激光器,光纤经内镜活检孔插入至病灶处,在准接触或接触情况下进行照射,输出功率50～80W,脉冲时间0.5～1.0s,通过激光照射使恶性狭窄再通和肿瘤缩小,从而使梗阻症状解除或部分解除,进食情况得到改善。大多数病人术中须静脉注入安定5～10mg,术后要严密观察病情变化,如需要时7～10天可重复
In our hospital, since 1990, Nd:YAG laser has been used for endoscopic treatment of 27 patients with inoperable or metastatic esophageal cancer who have undergone palliative treatment. The results are as follows: Data Methods Twenty-one males were included in this study. There were 6 females, aged 61-78 years old. Most of the squamous cell carcinomas were confirmed by X-ray, endoscopy, and biopsy before operation. Among them, 2 cases were in the upper segment, 14 in the middle segment, and 11 in the lower segment. Using JCW-IIB type Nd:YAG laser, the fiber was inserted into the lesion through the endoscopic biopsy hole and irradiated under quasi-contact or contact conditions. The output power was 50-80W, the pulse time was 0.5-1.0s, and the malignant stenosis was achieved by laser irradiation. Recanalization and tumor shrinkage, so that the obstructive symptoms are relieved or partially relieved, and the eating situation is improved. The majority of patients need intravenous injection of 5 to 10 mg intravenously. The condition of the patient should be closely observed after the operation. If necessary, 7 to 10 days can be repeated.
