Status Withdrawn

Clinical Trial Summary

Anal incontinence affects nearly 5% of the adult population in France. It is defined as the inability for a subject to retain matter and/or gas, outside of voluntary defecation episodes. It results in an uncontrolled loss of gas or stool through the anus. To quantify, anal incontinence clinical scores have been developed of which the most used is the Cleveland score (Jorge and Wexner). A Cleveland score ≥ 5 corresponds to anal incontinence. Crohn's disease is a chronic inflammatory disease that can affect the entire digestive tract as well as the anus. It leads to destruction of the intestinal wall if not treated early. The presence of ano-perineal involvement is a factor of severity and poor prognosis of Crohn's disease. The management of these ano-perineal lesions is particularly difficult because of the risks of destruction of the anal sphincter and recurrence of these lesions, as well as the consequences that they induce on anal continence, sexuality and quality of life. The prevalence of anal incontinence in Crohn's disease has been assessed in three studies by self-questionnaires. In 2013, it was studied in a cohort of British patients followed for chronic inflammatory bowel disease (IBD) (Hemorrhagic rectocolitis or Crohn's disease). Of the 3264 patients who responded to this questionnaire (32.5% of the cohort), 74% claimed to have anal incontinence and in 40% of cases it occurred regularly or a few times. In a study of 184 patients treated at an IBD expert center in Sri Lanka, anal incontinence was reported to be 26%. Only 5 patients reported regular anal incontinence. Vollebregt et al specifically studied the prevalence of anal incontinence in patients followed for Crohn's disease in a Dutch expert center. Of the 325 responses (62%), 20% of patients reported having had an episode of anal incontinence in the last 4 weeks. In these studies, the prevalence of anal incontinence varies according to the definition of anal incontinence (qualitative or quantitative estimate) and the population studied. No French study has been published on the prevalence of anal incontinence in Crohn's disease.

Clinical Trial Description

Many risk factors for anal incontinence have been identified in the general population. In IBD, the risk factors associated with anal incontinence are gender, age, a history of anal stenosis, a history of anal fistula surgery, and a history of colorectal surgery. There is currently only one study that has identified risk factors for anal incontinence specific to Crohn's disease. In this study, the risk factors for anal incontinence were loose stools, a history of colonic or bowel resection related to Crohn's disease, a stenosing phenotype of Crohn's disease, and ano-perineal involvement in Crohn's disease. The impact of anal incontinence on quality of life is major. Numerous trials show that this handicap is underestimated because of its shameful, embarrassing and intimate nature. The deterioration of quality of life, evaluated by the Inflammatory Bowel Disease Questionnaire (IBDQ) or Fecal Incontinence Quality-of-Life (FIQL) scores, is associated with the severity of anal incontinence in IBD. It is significantly degraded when there are several. episodes of weekly anal incontinence in patients followed for Crohn's disease. Only one study compared the quality of life of patients with ano-perineal involvement related to Crohn's disease with that of patients with only colonic or intestinal involvement. A significant deterioration in quality of life was reported in those with anoperineal involvement related to Crohn's disease. One of the therapeutic targets to be achieved in Crohn's disease is the "patient related outcomes" (PRO), i.e. the functional handicap secondary to the disease that is reported by the patient. Anal incontinence is one of the disabilities related to Crohn's disease. The aim of treatment is to stop the handicap and thus to improve the quality of life. The aim of this study is to evaluate the prevalence, risk factors and impact on quality of life of anal incontinence in a French cohort of patients with Crohn's disease. ;
