Improved Endoscopic Management of Severe Upper Gastrointestinal Hemorrhage Using a New Wide-Channel Endoscope

Abstract

Problems in emergency endoscopy for upper gastrointestinal bleeding may arise due to blood and food debris preventing proper endoscopic vision and orientation. We present here a new big channel endoscope with a 6 mm suction and drainage channel that achieved complete evacuation of stomach contents in 122 of 123 patients with upper gastrointestinal bleeding, in whom complete gastric cleaning and identification of the bleeding source had proved impossible using standard endoscopes. Gastric emptying using the big-channel endoscope was possible within five minutes in all successful cases. Optimal conditions for therapeutic procedures were therefore provided. The size of the instrumentation channel may open up new indications also for non-emergency endoscopic diagnosis and treatment.
