When the authors of this chapter reviewed the medical literature for endoscopic treatment of significant lower GI bleeding (at the time, n=286 over 8 publications), hemorrhage was successfully arrested in 70% of patients, with a rebleeding rate of 15%.

Hunter et al evaluated 222 GI endoscopic laser procedures in 122 patients and reported hemorrhage was arrested in 84% of the patients with GI bleeding. [74] No perforations were reported in this series, but one death occurred and was attributed to laser therapy in a patient with duodenal ulcer and gastroduodenal artery bleeding.

Forty patients with GI AVMs underwent 72 photocoagulation sessions with mostly argon laser; 15 of the 40 patients had significant hemorrhage from colonic AVMs; of those 15, there were no deaths following ablation.
