Brief Summary:
Determine the optimal therapeutic combination associated with complete clinical and anatomical remission of anal suppurations of Crohn's disease at 12 months.

Condition or disease Intervention/treatment
Crohn Disease Anal Suppurations Drainage Procedure Procedure: surgical treatment

Detailed Description:
The management of anoperineal suppurations of Crohn's disease is most often based on clinical practice recommendations, the results of randomized controlled trials and also the analysis of monocentric cohort studies from expert centres. In these latter studies, there is an overall improvement in patients during follow-up with a high level of satisfaction (two thirds of cases), often assessed by the operator himself or the clinician who provides therapeutic management. The most striking finding is the one that highlights the use of combined therapeutic strategies combining immunosuppressants, biotherapies, antibiotics, surgical drainage and surgical reconstruction procedures to varying degrees. Thus, the absence of fistula pathway flow in the long term is the consequence of both maintenance treatment with biotherapies and several surgical procedures. When the characteristics of fistula pathways considered healed on clinical examination are analysed by MRI exploration, an active unhealed pathway persists in two thirds of cases, again emphasizing the inadequacy of clinical examination as a means of assessing recovery. For this reason, fistula pathway closure strategies do not provide much greater benefit than simple removal of the drainage loop. Conversely, medical treatment optimization strategies based on MRI evaluation of the therapeutic response have demonstrated high efficacy. It is necessary to (re)define the therapeutic management of patients with anoperineal lesions. This strategy must be based on a better initial stratification of patients based on prognostic factors derived from available scientific data. A second step consists in setting therapeutic efficacy objectives that take into account the control of the inflammatory component of anal Crohn's disease and the preservation of the anatomical and functional capital of the anus. Only a large prospective cohort at the national level provides the opportunity to study these prognostic factors and to specify the level of optimal therapeutic responses

Intervention Details:
  • Procedure: surgical treatment
    surgical drainage and/or surgical reconstruction procedures to anoperineal suppurations according to the doctor's decision

Primary Outcome Measures :
  1. Clinical and anatomical healing [ Time Frame: 12 months. ]

    The healing of anal fistula is defined by the combination of two criteria at 12 months :

    • MRI criteria = absence of a T2 hyper signal from the path(s) AND the absence of an abscess AND
    • Complete clinical response = no pain, no discharge, and no drain
