Malignant esophageal obstruction in patients with carcinoma of the esophagus and adenocarcinoma of the distal esophagus usually indicates far-advanced disease. Palliative therapy with the neodymium-yttrium, aluminum, garnet laser has been proposed as an alternative to more invasive procedures that do little to improve the quality of life or prolong survival. Fifteen patients were treated with endoscopic laser therapy. A previously described technique was used to treat the first ten patients; the remaining five were treated with a single-session therapy method. This new technique allowed more rapid completion of therapy (1.4 treatments over 2.2 days vs 2.9 treatments over 7.8 days) without sacrificing safety. Single session therapy using this laser is recommended as the treatment of choice in patients with carcinoma of the esophagus with obstruction that is surgically or radiotherapeutically incurable.
食管癌和食管远端腺癌患者出现的恶性食管梗阻通常表明病情已发展到晚期。有人提出用钕钇铝石榴石激光进行姑息治疗,作为对那些对改善生活质量或延长生存期作用不大的更具侵入性手术的替代方法。15例患者接受了内镜激光治疗。对前10例患者采用了先前描述的技术;其余5例采用单疗程治疗方法。这种新技术能更快速地完成治疗(2.2天内进行1.4次治疗,而之前是7.8天内进行2.9次治疗),且不影响安全性。对于手术或放疗无法治愈的伴有梗阻的食管癌患者,建议使用这种激光进行单疗程治疗作为首选治疗方法。
