Video Endoscopy and CLO Test (DROSI)

The Video Endoscopy and CLO Test (DROSI) is a diagnostic procedure that involves the use of a flexible tube with a camera, inserted through the mouth or nose, to visualize the esophagus, stomach, and the upper part of the small intestine. During this test, a small biopsy may be taken to assess for the presence of Helicobacter pylori bacteria, which can cause gastritis and peptic ulcers, and to evaluate any abnormalities in the digestive tract. This procedure is typically performed under sedation to ensure patient comfort and safety.
