Summary

This study tests whether a fish skin device called Kerecis SurgiClose can help heal anal fistulas and related wounds that won't close on their own. Twenty adults with cryptoglandular fistulas will receive the fish skin patch during a procedure. Doctors will check if the fistula is healed 6 months later by looking for no drainage or infection.
