This article discusses the various kinds of laser therapy used in endoscopic surgery and their respective indications. Following a brief introduction into the basics of laser-tissue-interaction it is shown how less expensive treatment modalities have narrowed the range of laser applications to very specific purposes. In upper gastrointestinal bleeding argon and KTP lasers are mainly used for treatment of pigmented gut lesions. In malignant disease the combined use of balloon dilatation and laser irradiation has proved efficient in restoring patency to the gastrointestinal tract. Argon and CO2 lasers are used by gynaecologists for ablation of endometrioma. In an assessment of future prospects it is concluded that the lasting value of the laser lies in its ability to selectively destroy pigmented pathologic tissues.
本文讨论了在内镜手术中使用的各种激光疗法及其各自的适应症。在简要介绍激光与组织相互作用的基本原理之后，展示了成本较低的治疗方式如何将激光应用范围缩小到非常特定的目的。在上消化道出血中，氩激光和KTP激光主要用于治疗肠道色素沉着病变。在恶性疾病中，球囊扩张术和激光照射联合使用已被证明能有效恢复胃肠道通畅。妇科医生使用氩激光和二氧化碳激光来消融子宫内膜瘤。在对未来前景的评估中得出结论，激光的持久价值在于其选择性破坏色素沉着病理组织的能力。
