Effectiveness of Mannitol Versus Polyethylene Glycol Electrolyte Dispersion as a Salve for Patients With Inadequate Bowel Preparation: a Randomized Controlled Clinical Trial

For patients with inadequate bowel preparation, current guidelines recommend either remedial measures or rescheduling the endoscopy, but previous surveys have found that approximately 30% of patients do not follow medical advice to reschedule the examination if it is rescheduled, while those who take remedial measures on the same day are more compliant, so remedial measures may be a better option than rescheduling the examination. As for the remedy regimen, it has been demonstrated that oral PEG is superior to the enema regimen in terms of bowel cleansing, but PEG is very resistant to be taken by most patients due to its poor taste and the larger doses required, resulting in poor bowel preparation and poor compliance. In contrast, oral mannitol has the advantages of small dose and good taste, and patient compliance may be higher.
