Initial clinical experience with the fluorescein string test has indicated that it is a rapid, accurate, and safe method for localization of the site of bleeding in patients with upper gastrointestinal tract hemorrhage (1, 2). Since the initial clinical studies were carried out, modifications in methods have been made, and further experience has been acquired. The purpose of this paper is to describe the refinements of methods, to analyze the findings in 122 previously unreported cases, and to compare them with the results of upper gastrointestinal barium studies.
The test was performed when the patients were actively bleeding as
