The high mortality rate of up to 64% as a result of emergency for gastrointestinal hemorrhage indicates the need for a reliable method for endoscopic bleeding control. By developing a special flexible endoscopic laser transmission system it was possible to transmit high-power Nd-Yag laser radiation, which is especially effective in massive hemorrhages. In 1 1/2 years 186 (94%) of 198 bleeding incidents in 150 unselected patients could be controlled by endoscopic laser irradiation (varices: 60; Mallory-Weiss tears: 14; ulcers: 101; multiple erosions: 11).
因胃肠道出血急诊导致的高达64%的高死亡率表明，需要一种可靠的内镜下控制出血的方法。通过开发一种特殊的柔性内镜激光传输系统，能够传输高功率钕钇铝石榴石激光辐射，这种辐射在大量出血中特别有效。在1年半的时间里，150例未经挑选的患者发生的198次出血事件中有186次（94%）可通过内镜激光照射得到控制（静脉曲张：60例；马洛里-魏斯撕裂：14例；溃疡：101例；多发性糜烂：11例）。
