What the trial is, and whether it could suit you
Autologous ADSVF constitutes an innovative therapeutic strategy that concentrates various types of regenerative stem cells and paracrine factors able to promote angiogenesis and tissue repair. Together with the ease of collection from a minimally manipulated lipoaspirate, the unique properties of ADSVF offer new opportunities for fistulas' healing in patients with CD. The use of ADSVF is currently developed in many clinical fields based on safety and efficacy data.
Our ADICROHN pilot study evaluating safety and tolerance of local administration of autologous ADSVF with microfat in CD patients with complex perianal fistula refractory to conventional medical and surgical therapy showed that this novel therapeutic approach appears feasible and safe.
However the therapeutic potential of local this combined treatment in healing refractory perianal Crohn's fistulas still remains to be demons
