Seven men and five women with nonresectable esophageal carcinoma were treated endoscopically with the neodymium-YAG (yttrium-aluminum-garnet) infrared laser. Before laser fulguration, tumors were dilated directly with metal olive dilators. Before treatment, mean tumor length was 5 cm with luminal occlusion averaging more than 80%. After a mean of 3.3 treatment sessions spanning 18.5 days, all patients had substantial immediate palliation. Continued symptomatic relief was noted during follow-up (mean, 83 days; range, 8 to 206 days).
7名男性和5名女性患有无法切除的食管癌，接受了钕钇铝石榴石（neodymium-YAG）红外激光内镜治疗。在激光凝固术前，肿瘤直接用金属橄榄形扩张器进行扩张。治疗前，肿瘤平均长度为5厘米，管腔闭塞平均超过80%。经过平均3.3次治疗，历时18.5天，所有患者均立即获得显著的症状缓解。在随访期间（平均83天；范围8至206天），症状持续缓解。
