A new regimen of bowel preparation for PillCam colon capsule endoscopy: a pilot study

Abstract

Background: Colon capsule endoscopy (CCE) represents a new diagnostic, endoscopic technology for colonic exploration. Current protocols of preparation led to discordant rates of adequate cleansing level or CCE excretion.

Aim: To evaluate the effect of a new regimen of bowel preparation for CCE on colon cleansing levels and on rate of capsule excretion.

Study: 60 patients were prospectively enrolled. The new regimen of preparation consisted of a split regimen of PEG administration and of a 45 mL dose of sodium phosphate (NaP). Four senna tablets and a low-residue diet were also included. CCE excretion rate, colon cleansing, and accuracy were assessed.

Results: Forty-six patients were included in the final analysis, 13 patients (22%) being excluded because of preparation protocol deviations and one due to CCE technical failure (2%). At CCE, bowel preparation was rated as good in 78% of patients, fair in 20% and poor in 2%. CCE excretion rate occurred in 83% of patients. CCE sensitivity and specificity for significant findings was 100% and 95%, respectively.

Conclusions: The combination of a split-dose of PEG solution with a low dose of NaP boosters resulted in high rates of adequate cleansing level and CCE excretion.
