OBJECTIVE: Reconstructive proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical treatment of ulcerative colitis (UC) and familial adenomatous polyposis (FAP). The aim of our study was to evaluate the functional results of this procedure and to assess its impact upon patient quality of life (QoL). METHODS: We evaluated QoL and functional results in patients who had undergone IPAA using two self-rating questionnaires: 1) Medical Outcome 36 item Health Survey (SF-36); and 2) a specific questionnaire evaluating various aspects of anorectal and urogenital function. RESULTS: 107 patients (median age 38 [range 17-69] years) underwent reconstructive proctocolectomy with IPAA between 1981 and 2002. Median duration of follow-up was 83 (range 4-230) months. 66 patients (61%) answered both questionnaires. Two thirds of patients have more than five bowel movements per day and one bowel movement at night. Whilst true faecal incontinence is exceptional, episodes of soiling are reported by 25% of patients. Regarding QoL in this population, the two scores of the SF-36, which summarise physical and mental health status (Physical Component Summary and Mental Component Summary) were 54.6 and 45.8, respectively (both are 50 in the general population). CONCLUSION: Our data indicate that, as measured with SF-36 questionnaire, QoL after IPAA is close to normal. However, good quality of life is not a surrogate for good functional results. Despite excellent control of continence during the day, IPAA is often associated with night time bowel movements and soiling.
