Comparing surgery and hair removal for pilonidal disease treatment
Official title: Comparing Operative vs Non Operative Treatment for Pilonidal Disease
Run by Stanford University · NCT05439291 · Data updated 2026-11-12
This study is testing whether people with pilonidal disease can avoid surgery by just keeping up with regular hair removal after their symptoms go away.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients aged 8 years and older with pilonidal disease being treated at Stanford Healthcare.
✕Probably not a fit
Patients who cannot read, write, or understand English or Spanish, or those with intellectual disabilities that prevent comprehension of the study materials will not benefit.

What this trial studies
This study evaluates whether surgical excision is necessary for patients with pilonidal disease who follow a regular hair removal regimen, such as laser epilation, after their initial symptoms resolve. It involves a randomized controlled trial where participants will be assigned to either continue with hair removal alone or undergo surgical excision in addition to hair removal. The study aims to assess the effectiveness of these approaches in preventing recurrence of the disease, which can cause significant discomfort and social challenges for affected individuals. Patient surveys and clinical notes will be utilized to gather data on outcomes and experiences.
Why it matters
Potential benefit: If successful, this study could provide a less invasive treatment option for patients with pilonidal disease, reducing the need for surgery.
How similar studies have gone: While the standard treatment involves surgical excision, this approach of comparing non-operative management with surgery is relatively novel and has not been extensively tested.
