Oral mannitol as a preparation for double contrast barium enema

Area of Science:

• Gastroenterology
• Medical Imaging

Background:

• Oral mannitol is a purgative used for colonoscopy preparation.
• Its effectiveness for barium enema preparation has been suboptimal.
• Improving bowel clearance is crucial for diagnostic accuracy.

Purpose of the Study:

• To assess methods for enhancing bowel preparation using oral mannitol.
• To compare mannitol-based regimens with established lavage techniques.
• To determine the optimal preparation for double contrast barium enema.

Main Methods:

• Evaluation of divided mannitol dosage.
• Assessment of preliminary oral metoclopramide.
• Inclusion of a clear fluid diet.
• Comparison of the best mannitol regimen against a standard lavage technique.

Main Results:

• Divided dosage and a clear fluid diet significantly improved bowel clearance.
• Oral metoclopramide showed no significant benefit.
• The optimized mannitol regimen achieved 38% totally clear bowels versus 33% with lavage.

Conclusions:

• Oral mannitol, combined with a clear fluid diet, is a satisfactory preparation for double contrast barium enema.
• A recommended regimen using these components improves patient preparation.
• This approach offers a viable alternative for colonoscopy preparation.
