How surgical approach and anatomy affect wound opening after pilonidal sinus surgery

Official title: A Multicenter, Prospective, Observational Study on Factors Affecting Wound Dehiscence in Pilonidal Sinus Surgery: The Impact of Anal Proximity, Morphological Stage, and Surgical Technique (ORIPIS)

Run by Ankara Etlik City Hospital · NCT07370714 · Data updated 2026-11-12

We will see if how close the sinus is to the anal verge, the disease stage, and the surgical technique affect the chance of the wound reopening after pilonidal sinus surgery in adults having routine care.

Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with pilonidal sinus disease who are having planned (non-emergency) pilonidal surgery at the enrolling center and can provide informed consent.

Probably not a fit

Patients undergoing emergency surgery, those with prior pilonidal surgery at the same site, or those unable to complete postoperative follow-up are unlikely to benefit from participation.

What this trial studies

This multicenter prospective observational study will enroll adults undergoing planned pilonidal sinus surgery and record clinical, anatomical, and surgical details. Key data include distance from the pilonidal sinus to the anal verge, morphological disease stage, and the specific closure or excision technique used. Participants will be followed after surgery and wounds will be assessed for dehiscence and healing outcomes. Analyses will identify factors associated with wound reopening to help guide surgical choices.

Why it matters

Potential benefit: If successful, the findings could help surgeons choose techniques and manage patients to reduce wound reopening and improve recovery after pilonidal surgery.

How similar studies have gone: Previous observational reports have suggested that anatomy and surgical technique affect wound healing after pilonidal surgery, but results are mixed and prospective multicenter data are limited.
