The First Endoscopic Laser Coagulation in the Human Gl-Tract

Abstract

Preliminary report on the first endoscopic laser coagulations in the human gastrointestinal tract. The successful light coagulations were carried out on non-bleeding colonic haemangiomas and on a bleeding gastric ulcer. For the first time, a plastic light-guide that could be passed through the instrument channel of an endoscope, served as transmission system.
