Background Video capsule endoscopy (VCE) is an established diagnostic tool for the investigation of small bowel (SB) pathology. Bowel preparation prior to VCE may improve visualization, transit time, and diagnostic yield. We aimed to evaluate the “real-life” experience comparing two different preparation protocols in patients undergoing SB VCE. Methods We performed a retrospective analysis of prospectively collected data from SB VCE procedures, performed in two tertiary care medical centers in Israel. VCE procedures performed at “Sheba Medical Center” used a 2-L polyethylene glycol (PEG) bowel preparation (n=360) while VCEs performed at “Rambam Health Care campus” used a clear liquid diet plus 12-h fast protocol (n=500). A dichotomous preparation scale (adequate, inadequate) was used to classify cleansing quality. Data collection included patient and procedural details. The proportion of VCE procedures with adequate bowel preparation and the overall positive SB findings in the two different bowel preparation protocols were evaluated. Results SB completion rates were higher in the PEG protocol (96% vs. 83%, P<0.001) and SB passage time was significantly faster in the PEG protocol (mean 217±73 vs. 238±77 min, P<0.001). Bowel preparation quality was similar between groups (8% vs. 7% inadequate preparation, P=0.591). Overall positive SB findings were similar between the two groups (57% clear liquid fasting only vs. 51% PEG protocol, P=0.119). Conclusion In this large cohort, a 2-L PEG protocol had similar preparation quality and diagnostic yield compared with clear liquid fasting.
