Laser-induced hemostasis in the canine stomach. Use of a flexible fiberoptic delivery system.

A flexible fiberoptic system has been used to deliver visible laser light into the upper gastrointestinal tract to arrest bleeding from various induced lesions. This procedure has achieved hemostasis at bleeding sites in the gastrointestinal tract of animals and suggests that bleeding lesions in the heman may be treated similarly without resort to surgical intervention or intensive medical management.

Endoscopic Nd:YAG laser treatment of severe radiation injury of the lower gastrointestinal tract: long-term follow-up.

We report a series of patients with severe radiation injury treated with endoscopic laser photocoagulation. Eight patients with recurrent lower gastrointestinal bleeding secondary to procosigmoiditis were treated with endoscopic Nd:YAG laser therapy. Patients were followed for an average of 21.7 months after the first laser treatment. Average transfusion requirements and hospital admissions per patient-month were 0.93 and 0.27, respectively, in the prelaser period and 0.18 and 0.06, respectively, in the entire period following the first laser treatment. A total of 26 laser treatments were performed. There were three major (prolonged ileus) and one minor (pain) complication. We conclude that endoscopic Nd:YAG laser photocoagulation is a safe, effective, and lasting treatment in severe, symptomatic radiation injury of the lower gastrointestinal tract.
