[Hemostatic effects of the argon laser on the gastric wall of the dog. II. Effects of the laser on 53 hemorrhagic ulcers of the gastric mucosa].

The authors made a histopathological study of 53 haemorrhagic ulcers of the gastric mucosa of the dog, photocoagulated using an Argon laser apparatus (delivering a power of 6 watts at the tip of the fibre). Haemostasis was obtained in less than 10 sec. in all cases where photocoagulation was performed by small applications of 1.5 sec. to the edges of the ulcer. There were no cases of perforation or muscularis damage. Healing of the lesions was complete or well under way at 15 days.
