利用内窥镜激光进行消化道止血早已获得成功,并有不少报导。目前,内窥镜激光有两大类:一类是氩离子激光,主要是以Frühmorgon为中心的埃罗伦根大学的研究小组在进行研究,他们认为氩离子激光比较安全;另一类是新发展的Nd-YAG激光,以Kiefhaber、Nath为中心的慕尼黑大学的研究小组正致力于这方面的研究。这种激光的功率较大,能达到组织深部。两个研究小组的研究对比如下:
The use of endoscopic laser digestive tract hemostasis has long been successful, and there are many reports. At present, there are two major types of endoscopic lasers: one is argon ion laser, mainly Frühmorgon as the center of the University of Ehringen research team in the study, they think argon ion laser safer; the other is a new The development of Nd-YAG laser, Kiefhaber, Nath Center for the University of Munich’s research team is working on this area. The power of this laser is larger and can reach deep into the tissue. A comparison of the two research groups is as follows:
