Brief Summary:
multicentre randomized controlled prospective study aimed at evaluating the efficacy of the infiltration of microfractured adipose tissue in the healing of perianal fistulas not-responding to treatment with biologics, in order to improve the quality of life and significantly reduce the risk of definitive ostomy.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of participants with Combined remission [ Time Frame: 24 weeks ]
    The primary outcome of the study will be the evaluation of the difference between the two experimental groups in terms of "combined remission" which will be defined at 24 weeks from surgery to clinical evaluation as "absence of drainage at a slight digital compression". of all treated external orifices that were draining at baseline and pelvic MRI as the absence of abscesses> 3 mm in correspondence of the treated perianal fistulas


Secondary Outcome Measures :
  1. Number of participants with Clinical remission [ Time Frame: 2-4-8-12-24 weeks ]
    Comparison between the two experimental groups in terms of clinical remission at 2 weeks (± 2 days), 4 weeks (± 2 days), 8 weeks (± 2 days), 12 weeks (± 3 days) and 24 weeks ± (5 days) from surgery (ie the closure of all external orifices treated that were draining at baseline despite a slight digital compression) with the presence of abscess collections> 3 mm on MRI.
