BACKGROUND: Oral sodium phosphate solution is better tolerated than polyethylene glycol when used for colonoscopy preparation, but visibility of the lumen can be impaired because of the presence of bubbles.
METHODS: We studied 86 patients receiving either simethicone (n = 42) or placebo (n = 44) in addition to oral sodium phosphate to determine if simethicone improved visibility during colonoscopy. Colonoscopy was performed by a single blinded investigator. Five areas of the colon (rectosigmoid, descending, transverse, ascending, and cecum) were assessed for the presence of bubbles on withdrawal of the endoscope. Bubbles were scored as follows: 0, minimal or none; 1, covering half the lumen; 2, covering the entire circumference; 3 filling the entire lumen.
RESULTS: Thirteen patients in the placebo group and only one in the simethicone had significant bubbles ( > or = 1). Additionally, the mean bubble scores were greater in the placebo group in each region of the colon (p < or = 0.05 in rectosigmoid and ascending colon).
CONCLUSIONS: This study indicates that taking simethicone with an oral sodium phosphate preparation can improve colonic visibility by diminishing the presence of bubbles. Better visualization could improve detection of mucosal pathologic lesions.
