Purpose : To compare small bowel distension and side effects between a diluted polyethylene glycol (PEG) solution and a low-density (0.1% w/v) barium sulfate suspension (LDBSS) for CT enterography (CTE) preparation.
Materials and Methods : Total 173 consecutive patients who underwent CTE were enrolled in this study. The LDBSS (1 L) was used in 50 patients, and the diluted iso-osmotic PEG solution (1 L) was used in 123 patients. Two blinded radiologists independently scored jejunal and ileal distensions on a 5-point scale. To compare side effects between the two groups, the patients reported whether they had immediate complications after the administration of the oral contrast media.
Results : For ileal and jejunal distension, the diluted PEG solution showed no difference from the LDBSS for either reader (ileum: reader 1, median, 4; 4, interquartile range, 3?4; 3?4, p = 0.997; reader 2, median, 4; 4, interquartile range, 3.3?4.0; 3?4, p = 0.064; jejunum: reader 1, median, 2; 2, interquartile range, 2?3; 2?3, p = 0.560; reader 2, median, 3; 2, interquartile range, 2?3; 2?3, p = 0.192). None of the patients complained of immediate complications following administration of either of the oral contrast media.
Conclusion : The diluted PEG solution showed comparable bowel distension compared to LDBSS and no immediate side effects; thus, it can be a useful alternative.
