We report experimental results obtained by laser photocoagulation on hemorrhagic lesions induced in dogs. The aims of this study were 1) to evaluate the real efficiency of the YAG laser to ensure hemostasis of briskly bleeding lesions; 2) to determine the minimum energy density necessary to ensure hemostasis; 3) to assess the damage depth inside the gastric wall after photocoagulation; 4) to compare reepithelialization of treated ulcers with that of control ulcers; 5) to evaluate the safety margin for the clinical use of the YAG laser.
