Abstract

PURPOSE
The purpose of this study was to compare two bowel preparation agents, sodium phosphate solution with magnesium citrate solution.
MATERIALS AND METHODS
A total of 94 subjects that underwent a double-contrast barium enema were included in this study. Bowel preparation before performing the barium study was done by using a sodium phosphate solution in 47 subjects and by using a magnesium citrate solution in the other 47subjects. We evaluated the presence or absence of side effects when using these bowel preparation agents. Two radiologist who were blinded to the type of bowel preparation evaluated the quality of bowel preparation at the colonic segments (ascending, descending, and sigmoid colon) on the radiographs obtained by double-contrast barium enema, with regard to stool cleansing, water retention, barium coating and bubble formation.
RESULTS
The side effects, such as abdominal clamping pain, nausea, hunger pain and chill occurred more frequently in the sodium phosphate group than in the magnesium citrate group (p<0.001). Stool retention was more frequently found in the magnesium citrate group (p<0.001). However, no statistical difference was noted on the status of water retention and barium coating between two groups. Gas bubble formation was more commonly seen in the sodium phosphate group (p<0.001). The sodium phosphate solution appeared to be more effective in cleansing the right colon (p=0.001).
CONCLUSION
Sodium phosphate solution appears to be more effective for colonic cleansing, with a lower incidence of side effects, than when using magnesium citrate solution.
