The functional outcome and factors influencing the quality of life after ileal pouch anal anastomosis in patients with ulcerative colitis

Purpose: The aim of this study was to assess the bowel function and quality of life (QOL) in patients with ulcerative colitis (UC) after total proctocolectomy with ileal pouch anal anastomosis (IPAA). Methods: Two questionnaires [“Questionnaire sheet on the bowel function” and “Inflammatory bowel disease questionnaire (Japanese IBDQ)”] were sent to 121 patients with UC who underwent IPAA at Tohoku University Hospital. Seventy-nine patients (65%) participated in the study. Results: The median number of daily bowel movements was 6.5, which significantly decreased with postoperative time (≤ 1, 1–5, 5–15 years) and increased with age (< 45, ≥ 45 years at colectomy). The ratio of patients who usually had bowel movements at night also significantly decreased with postoperative time and increased with age. The median total IBDQ score was 180. A multivariate analysis showed that “trip activity”, “care about where the restroom is”, and “bowel movements in the day” were significant independent risk factors for the daily life satisfaction score. Conclusions: The bowel function and QOL were acceptable in patients with UC after IPAA; however, patients with a short postoperative time or older age had a lower functional outcome than others.
