Perianal disease and its impact on sexual life
This project will see how chronic perianal conditions (like fistulas, perianal Crohn’s, or pilonidal disease) affect sexual function and self‑esteem in adults who can complete Greek questionnaires.
-
ECMT-100 ECM hydrogel to close high transsphincteric anorectal fistulas
This trial tests a mucoadhesive ECM hydrogel (ECMT-100) placed into the fistula tract to try to close high transsphincteric anorectal fistulas in adults who have had a seton in place.
-
BioHealx device long-term follow-up for closing anal fistulas
This study will see if the BioHealx implant can close and keep closed anal fistulas in adults with a single continuous fistula who have had a draining seton.
-
Comparing collagen paste and mucosal advancement flap for treating fistula-in-ano
This study tests whether using collagen paste or surgery works better for healing high anal fistulas while keeping the anal sphincter functioning well.
-
Evaluating non-cutting seton placement for fistula-in-ano in children
This study tests how long a special thread, called a seton, should be used to treat fistula-in-ano in children to see which duration helps them feel better.
-
Using stem cells from umbilical cords to treat perianal fistulas in Crohn's disease patients
This study is testing if injections of stem cells from umbilical cords can safely help people with Crohn's disease heal complex perianal fistulas.
