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

R. M. Dwyer, B. J. Haverback, M. Bass and J. Cherlow

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.
