NCT07417202

Brief Summary

The purpose of this study is to determine the best method for cleaning wounds during surgery for patients with Stage 3 pilonidal disease. The investigators will compare the standard wound cleaning solution, saline, with a different solution called hypochlorous acid (Vashe, Urgo Medical) to see which one helps wounds heal faster after surgery.

Outcome Measures

Primary Outcomes (1)

  • Time to Wound Closure

    The primary outcome is the length of time (in days) that it takes the wound to close following surgery for pilonidal disease.

    From day of surgery to wound closure at ~14 days

Secondary Outcomes (1)

  • Recurrence of Disease

    Wound closure at ~14 days to time of event up to 2 years post-operation, measured at 3-month intervals

Study Arms (2)

Vashe

EXPERIMENTAL

Participants in this arm will have a hypochlorous acid solution used for wound irrigation intraoperatively.

Procedure: Hypochlorous Acid

Saline

NO INTERVENTION

Participants randomized to this arm will have a saline solution used for wound irrigation, which is the current standard of care.

Interventions

Hypochlorous acid will be used as the wound irrigation solution instead of the saline which is currently considered standard. All other aspects of the surgery will be the same across both arms.
