Preparations for colon capsule endoscopy: prospective and randomized comparative study between two preparations for colon capsule endoscopy: PEG 2 liters + ascorbic acid versus PEG 4 liters

Introduction: PillCam© colon capsule endoscopy (CCE) enables the study of colonic diseases in a safe and non-invasive way, although there are aspects that need to be improved. Current methods of bowel preparation lead to discordant rates of adequate cleansing and CCE excretion. Aims: To compare the efficacy of colon cleansing using two different regimes (2L PEG plus ascorbic acid versus 4L PEG alone) for PillCam Colon (C2) capsule endoscopy. Methods: Fifty eight patients included in this prospective study and randomized to: Group A, PEG plus ascorbic acid regimen (n = 28, 12 F/16 M) or group B, PEG alone regimen (n = 30, 14 F/16 M). The degree of cleansing was categorized into "excellent-good" or "fair-poor", according to Leighton's recently published preparation scale. CCE excretion rate and colon cleansing were assessed. Patients underwent to PillCam colon of second generation (C2). Results: Cleansing was considered to be excellent-good in 78 % of cases in group A and in 64 % of cases in group B, with no significant difference between the groups (p = 0.252). Nevertheless, when the grade of cleansing was analyzed in segments, a significant difference was found in the cecum and transverse colon. No differences were observed in the bubble effect between preparations. The excretion rate was 93 % in group A versus 70 % in group B (p = 0.043). Conclusions: These results suggest that a 2L PEG plus ascorbic acid regimen is at least as effective as a 4L PEG regimen. This regimen may be considered an effective alternative which would improve compliance because a smaller volume is required.
