What this trial studies

This is a first-in-human feasibility study aimed at assessing the safety and functionality of TIPS microspheres in treating perianal fistulas. The study involves a single delivery of bioabsorbable microspheres into the fistula tract following a standard internal flap procedure to close the internal opening. Participants will be monitored for healing, inflammation, abscess, sepsis, pain, and continence through various clinical assessments and tests. The goal is to demonstrate that TIPS microspheres do not compromise patient safety and facilitate natural healing.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with cryptoglandular perianal fistulas.

Not a fit: Patients with secondary fistulas, such as those caused by Crohn's disease or other specific conditions, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new, effective treatment option for patients suffering from perianal fistulas.

How similar studies have performed: While this approach is novel, other studies have explored similar bioabsorbable devices, but this specific application is untested.
