Pelashield™ PainGuard™ vs Restrata® in HS Surgery
Outcomes With Pelashield™ PainGuard™ Compared to Restrata® in Standard Two-Stage Excision and Closure for Hidradenitis Suppurativa: A Prospective Cohort With Retrospective Comparator
Who can join
Ages 18 and older · All sexes
Full eligibility criteria
Inclusion Criteria: * Adults (≥18 years) with a confirmed clinical diagnosis of HS requiring wide surgical excision. * Ability to provide informed consent in English. * Willingness and ability to attend routine postoperative follow-up visits to monitor healing and readiness for second-stage closure. Exclusion Criteria: * Non-English-speaking patients (due to consent and follow-up communication limitations). * Known allergy or hypersensitivity to wound matrix components (polyvinyl alcohol), local anesthetics, or silver. * Known sensitivity to lidocaine or history of cardiac conditions contraindicating lidocaine use (e.g., severe heart block, Adams-Stokes syndrome, Wolff-Parkinson-White syndrome). * Pregnancy or active breastfeeding. * Severe immunosuppression (e.g., chemotherapy within 3 months, solid organ transplant, uncontrolled HIV with CD4 \<200, or chronic systemic steroids \>10 mg prednisone-equivalent/day). * Uncontrolled diabetes (most recent HbA1c \>10% if available within 3 months). * Active systemic infection or sepsis at time of surgery. * Inability to complete postoperative follow-up through second-stage closure (e.g., plans to relocate).
About the study
Hidradenitis Suppurativa (HS) is a long-lasting skin condition that causes painful lumps and infections. In severe cases, patients need surgery to remove the affected skin. After surgery, a wound dressing called a wound matrix is placed over the area to help the skin heal.
This study will compare two different wound matrices:
Restrata®, which is the current standard treatment. Pelashield™ PainGuard™, a newer dressing that contains silver to reduce bacteria and lidocaine to help with pain.
The goal of this research is to find out if Pelashield™ PainGuard™ helps patients heal better after surgery than Restrata®. We will look at:
How quickly healthy granulation tissue (new healing tissue) forms How soon the wound is ready for the second surgery to apply a skin graft How often infections happen after surgery How much narcotic (opioid) pain medication patients need after surgery Patients who receive Pelashield™ PainGuard™ will be enrolled in the study going forward (prospective group). Patients who previously had surgery with Restrata® will be included through a review of their medical records (retrospective group). No additional procedures will be done outside of standard surgical care.
