Evaluation of three effervescent agents for double-contrast upper gastrointestinal radiography

Academic Article


  • The agent used to introduce gas into the stomach is an important factor in determining the quality of double-contrast upper gastrointestinal radiography. The efficacy of 3 effervescent agents formulated for use in double-contrast upper gastrointestinal radiography was evaluated in 300 patients. Patients found 2 granular preparations (E-Z-Gas granules and Baros) easier to swallow than a powdered agent (E-Z-Gas powder). Bubble formation and flocculation of barium in the stomach were less of a problem with Baros. Differences in mucosal coating and visualization of areae gastricae were not statistically significant. © 1981 Springer-Verlag New York Inc.
