Abstract:


Background: Adequate bowel cleansing is essential in achieving a good quality colonoscopy. However, one of the barriers in achieving a high-quality bowel cleansing is patient's tolerability. Different bowel preparations have been developed to improve tolerability while maintaining adequate bowel cleansing.

Objectives: We aim to explores pros and cons of commonly used bowel preparations, particularly highlighting the new ultra-low volume bowel preparation. Methods: Extensive literature search was carried out on various databases to evaluate effectiveness and side effects of different bowel cleansing agents including findings of recent clinical trials on ultra low bowel preparation.

Results: Polyethylene glycol (PEG) has been commonly used as a bowel prep. Due to its high volume required to ingest to achieve an adequate effect, it has been combined with various adjuncts to reduce the volume to make it more tolerable. Magnesium and phosphate based preps can achieve low volume but they can be associated with multiple side effects mainly electrolyte disturbances. Ultra low volume prep (NER1006) was achieved by combing PEG with ascorbic acid and its efficacy and side effects were demonstrated in three non-inferiority studies.

Conclusion: It is important to consider patient preferences, co-morbidities and tolerability and efficacy and side effect profiles when choosing bowel prep for patients undergoing colonoscopy. New ultra low bowel prep showed promising results in initial clinical trials but further real world post marketing data will inform its value in clinical practice.
