本文采用Nd-YAG激光器,其光纤能通过内镜活检通道插入,纤维头端距肿瘤5—10mm,用0.5-1.0秒/脉冲,功率50-80W,自食管从上而下的照射。照射处的癌组织即呈黑色炭化。如无效,隔日再进行照射,直到打开一条通道。本组27例晚期食管癌病人,照射后24小时即可进食,并可维持7-14天。总有效率88.9%。激光治疗可使恶性狭窄再通和肿瘤缩小,重建饮食通道,提高生存期。 This article uses Nd-YAG laser, the fiber can be inserted through the endoscopic biopsy channel, fiber tip from the tumor 5-10mm, with 0.5-1.0 seconds / pulse, power 50-80W, from the esophagus from top to bottom irradiation. The cancerous tissue at the irradiation site is charred in black. If it is not valid, it will be irradiated every other day until a channel is opened. This group of 27 patients with advanced esophageal cancer, 24 hours after irradiation can eat, and can maintain 7-14 days. The total efficiency is 88.9%. Laser treatment can make malignant stenosis recanalization and tumor shrinkage, rebuild dietary channels, and improve survival.
