Laser treatment with two-year follow-up for pilonidal cysts
Official title: Prospective Study on the Incidence of Recurrence in Laser Treatment of Pilonidal Cysts
Run by Centre Hospitalier Departemental Vendee · NCT07314632 · Data updated 2026-11-12
This project will see if laser surgery prevents pilonidal sinus recurrence within two years in adults who need the procedure.

Is this trial a fit for you?
✓Likely a good fit
Adults who require laser surgery for pilonidal sinus (including recurrent disease), can give informed consent, and are affiliated with the social security system are ideal candidates.
✕Probably not a fit
People under guardianship or other legal protection, those already in another interventional research protocol, or patients who do not receive laser surgery are unlikely to benefit from this observational follow-up.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective observational study of adult patients who undergo laser surgery for pilonidal sinus as part of routine clinical care. Participants will complete follow-up surveys at 1 year and 2 years to record clinical recurrence, defined as presence of a fistula in the intergluteal cleft. Enrollment includes primary and recurrent cases at two French centers, Clinique des Cèdres (Cornebarrieu) and CHD Vendée (La Roche-sur-Yon). The protocol excludes patients enrolled in other interventional research or those under legal protection orders.
Why it matters
Potential benefit: If successful, the results could give patients and surgeons clearer two-year recurrence rates after laser treatment to guide care and expectations.
How similar studies have gone: Previous small observational and randomized studies of minimally invasive laser approaches have reported promising short-term recurrence rates, but long-term comparative evidence remains limited.
