The main indications for laser therapy in the gastrointestinal tract are inoperable tumors of the esophagus, cardia and the recto-sigmoid. Exophytic tumors with a maximum length of the tumor stenoses between 5 and 7 cm are the best candidates for laser treatment. In gastroenterological stone centers, the laser-induced intracorporeal shock wave lithotripsy is now established. The sophisticated principle of the so-called photodynamic therapy is still in an experimental stage. Photodynamic therapy offers the option of curative therapy in small malignant or premalignant (Barrett esophagus with severe dysplasia) lesions.
胃肠道激光治疗的主要适应证为食管、贲门和直肠乙状结肠的无法手术切除的肿瘤。肿瘤最大长度在5至7厘米之间的外生性肿瘤是激光治疗的最佳候选对象。在胃肠结石治疗中心，激光诱导体内冲击波碎石术现已确立。所谓光动力疗法的复杂原理仍处于实验阶段。光动力疗法为治疗小型恶性或癌前病变（重度发育异常的巴雷特食管）提供了治愈性治疗的选择。
