New bandage aims to speed up healing of painful tailbone cysts
NCT ID NCT02011802
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special germ-trapping dressing (Sorbact) helps wounds heal faster after surgery for pilonidal sinus, a painful condition near the tailbone. About 250 adults took part, and researchers compared Sorbact to a standard dressing over 75 days. The goal was to see if 70% of wounds healed with Sorbact versus 50% with the standard dressing.
