Retrograde ileography: value of glucagon

Area of Science:

• Gastroenterology
• Radiology
• Medical Imaging

Background:

• Terminal ileum diseases are common.
• Retrograde ileography is crucial for evaluation.
• Spontaneous barium reflux into the terminal ileum during barium enema is infrequent.

Purpose of the Study:

• To determine if glucagon facilitates terminal ileum reflux during double-contrast colon studies.
• To assess the efficacy of glucagon in improving retrograde ileography.

Main Methods:

• Randomized, double-blind trial.
• Utilized glucagon in double-contrast colon examinations.
• Analyzed reflux frequency using multiple regression analysis.

Main Results:

• Glucagon significantly promotes barium reflux into the terminal ileum.
• Patient age, weight, and sex showed minimal impact on reflux frequency.
• Confirmed glucagon's role in facilitating distal small bowel examination.

Conclusions:

• Glucagon is an effective agent for enhancing retrograde ileography during double-contrast colon examinations.
• The use of glucagon can improve the diagnostic yield for terminal ileum pathology.
• Facilitates comprehensive evaluation of the distal small bowel.
