对急性上消化道出血,纤维内窥镜检查不仅用于诊断,并可为非手术性止血提供方法。几种热作用的疗法,包括钕钇铝石榴石(简称Nd-Yag)激光器、氩激光器、双极或单极电凝等,在动物模型中的止血效果已有过评价。但动物实验中采用Quinton溃疡是具有一些缺点的,如形成的溃疡深浅不一,出血的血管直径大小不同,出血速度可能较慢。这些模型造成的病变一般和病人的 For acute upper gastrointestinal bleeding, fibro-endoscopy is used not only for diagnosis but also for non-surgical hemostasis. Several thermo-active therapies, including neodymium-yttrium aluminum garnet (Nd-Yag) lasers, argon lasers, bipolar or unipolar coagulation, have been evaluated in animal models. However, the use of Quinton’s ulcer in animal experiments has some shortcomings. For example, the ulcer is formed in different shades, the diameter of bleeding blood vessels is different, and the bleeding speed may be slower. These models cause lesions in general and in patients
