Comparison of cleansing effects and colonic distension observed with two polyethylenglykol-solutions (PEG) containing bowel preparation techniques prior to CT-Colonography (CTC). MATERIALS AND METHODS:103 patients that received CTC were retrospectively evaluated. 51 patients received bowel preparation 1 (BP1; GoLytely based PEG-solution), 52 preparation 2 (BP2; sulphate free PEG-solution based on a NuLytely formulation). On multi-planar-reformatted (MPR) images, fluid residuals and colon distension were assessed in 5 colonic segments, from the ascending colon to the rectum. RESULTS: On average, significantly (p<0,001) lower fluid residuals were assessed when using BP2 regardless of the patients position. In prone position, a significantly lower fluid level was observed in the sigmoid using BP2. The average maximum diameter for the whole colon was 5,2 cm ± 0,6 in prone position and 4,8 cm ± 0,6 in the supine position in BP1 (p<0,01). In BP2 the average maximum diameter measured for the whole colon was 5,3 cm ± 0,6 in prone position and 4,7 cm ± 0,5 in supine position respectively (p<0,001). CONCLUSION: Overall, lower fluid residuals were scored using BP2. In both preparation groups we achieved better colonic distension in prone position. The sigmoid colon was always the most demanding segment to distend.
