Quality of colonoscopy preparation in patients with inflammatory bowel disease: retrospective analysis of 348 colonoscopies

Objective Our aim was to prospectively assess bowel preparation in patients with inflammatory bowel disease (IBD) and to determine the impact of disease-related factors on preparation efficacy because few studies have addressed this issue. Methods We conducted a retrospective analysis of data collected from a cohort of patients with IBD enrolled at a tertiary center in Bucharest, Romania. Patients were evaluated every 12 months, with each study visit including collection of clinical, biological, and endoscopic data. We reviewed 348 colonoscopies from 169 consecutive patients prospectively followed for a median length of 2 (0–6) years. Results The median total Boston score and median score per bowel segment in our cohort were optimal at 6 (range 0–9) and 2 (maximum 3), respectively. There was no difference in bowel preparation between patients with endoscopic activity and patients with mucosal healing (median total Boston score 6). Disease- and patient-related parameters did not influence the quality of bowel preparation. Conclusions The quality of bowel preparation in patients with IBD was optimal for our cohort, and disease-related parameters did not significantly influence preparation efficacy.
