Endoscopic laser coagulation of gastro intestinal hemorrhage



Endoscopic laser coagulation of gastro intestinal hemorrhage



Stomach & Intestine (Tokyo) 15(7): 733-738



The results of fundamental and clinical investigations of controlling bleeding in the digestive tract are described. Bleeding of the mucosa was artificially produced in a dog with an irradiated laser. Hemorrhage stopped in 7.4 and 5.5 s with an output of 45 and 60 W, respectively. There were cases in which bleeding was not controlled and an output of more than 45 W was necessary. In arterial bleeding from the artificially damaged gastric mucosa of the dog the amount of hemorrhage was .apprx. 6 ml/min. Bleeding ceased in an average of 18 s with an output of 45 W and 15.7 s with 50 W output. The diameter of the bleeding mesenteric arteries controllable by laser, was up to 1 mm. The effect of the control of bleeding differed according to the amount of blood flow and its velocity. Osler's disease and especially stress ulcer, where the blood vessels of the lesion are not exposed, bleeding was controlled with relative ease by laser irradiation. Arterial bleeding of gastric ulcer can be managed temporarily, but lasting arrest of hemorrhage could not be expected sufficiently. It was difficult to control bleeding from the arteries more than 2 mm in diameter.
