Brief Summary

Background Perianal fistula may affect 15-50% of patients with Crohn's disease (CD). Treatment is complex, requiring a multidisciplinary approach. Darvadstrocel (allogeneic mesenchymal cells obtained from lipoaspirates) was approved in 2018 by the European Medicines Agency and Spanish Agency of Medicines and Medical Products as a treatment for fistulas in CD. Recent European Crohn's and Colitis Organisation (ECCO) andSpanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) guidelines state that darvadstrocel is effective with a favourable safety profile,with a strong level of evidence (level 2).With this study we want to see the real efficacy of darvadstrocel in a Spanish population after 6 months of follow-up.

Outcome Measures

Primary Outcomes (4)

  • Number of Participants with clinical remission

    Clinical remission was defined as closure of all previously draining external openings treated with darvadstrocel, despite gentle finger compression

    6-month

  • Number of Participants with clinical response

    Clinical response was defined as closure of ≥50% of previously draining external openings treated with darvadstrocel, despite gentle finger compression

    6-month

  • Number of Participants with clinical radiographic healing

    Complete radiographic healing was defined as an MRI result with no fluid collection \>2cm in all dimensions, no oedema and no inflammation nor sign of active inflammatory response;a remnant fistula tract scar may remain

    6-month

  • Number of Participants with combined clinical-radiological response

    Combined clinical-radiological response, a new concept, was used to describe patients who achieved both clinical remission and complete radiological healing.

Study Population

All patients with complex anorectal fistulas associated with CD treated with darvadstrocel in the 14 dedicated centres from 29 November 2019 to 21 April2022 will be enrolled in the study.

You may qualify if:

  • )complex fistula in a patient with CD
  • )failure of conventional and anti-tumour necrosis factor treatment
  • )absence of collection s\>2cm confirmed by pelvic MRI scan at the time of surgery

You may not qualify if:

  • Patients with a diagnosis of rectovaginal fistula, rectal stenosis or severe active proctitis were excluded
