A Randomized Prospective Trial Comparing Polyethylene Glycol and Sodium Picosulphate With Magnesium Citrate

Adequate bowel cleansing is important for a completeness of colonoscopy and detection of colon polyps. Inadequate bowel preparation leads to longer duration of colonoscopy and obscured mucosal visualization resulting in missed lesions.
Bowel cleansing agents are simply classified into the large volume, iso-osmotic polyethylene glycol (PEG) based solutions or the small volume osmotically active agents, such as sodium picosulphate with magnesium citrate (SPMC).
There are rare reports that compare directly conventional polyethylene glycol (PEG) solution and sodium picosulphate with magnesium citrate (SPMC) for bowel preparation in korea.
The aim of this study is to compare the efficacy, safety, and tolerability of different regimens of SPMC and PEG solution.
