In a prospective trial with and without laser therapy the outcome on 105 patients was evaluated according to a defined protocol and terminology. Only patients with actively bleeding lesions during early endoscopy had laser therapy. Patients showing evidence of recent bleeding or no bleeding had none. Defects of the laser equipment or impossibility of reaching a bleeding lesion prevented its use in some patients (control group). There was no difference concerning rate of recurrent bleeding or mortality. Controlled trials with defined groups of patients are urgently needed.
在一项有激光治疗和无激光治疗的前瞻性试验中，根据既定方案和术语对105例患者的治疗结果进行了评估。只有在早期内镜检查时出现活动性出血病变的患者接受了激光治疗。有近期出血迹象或无出血的患者未接受治疗。激光设备故障或无法到达出血病变部位导致部分患者（对照组）未接受激光治疗。复发出血率或死亡率方面没有差异。迫切需要针对特定患者群体进行对照试验。
