Hypotonic duodenography with glucagon. A clinical comparison study.

This clinical double-blind study shows that glucagon (2 mg) is a valuable agent for hypotonic duodenography. Pro-Banthine (45 mg) is slightly more effective as a hypotonic agent, but there is no doubt that its use is associated with more side effects and subsequent patient discomfort; contraindications to its use are more commonly encountered in a general hospital population.
