An observational study in Pilonidal Sinus Disorder, sponsored by Ankara Etlik City Hospital. Recruiting at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-01-27.
Sponsored by Ankara Etlik City Hospital · Observational
The goal of this multicenter, prospective, observational study is to investigate factors associated with wound dehiscence following pilonidal sinus surgery. The main questions it aims to answer are:
Does the proximity of the pilonidal sinus to the anal verge influence the risk of postoperative wound dehiscence? How do the morphological stage of the disease and the surgical technique used affect wound healing outcomes? Patients undergoing pilonidal sinus surgery as part of routine clinical care will be enrolled prospectively across multiple centers. Clinical, anatomical, and surgical characteristics-including anal proximity, morphological stage, and type of surgical technique-will be recorded. Participants will be followed postoperatively, and wound outcomes will be assessed to identify factors associated with wound dehiscence.
109 studies on the registry are indexed under Pilonidal Sinus; 32 are open to participants now.
This study's planned enrollment of 250 is above the median of 145 across 37 observational studies indexed under Pilonidal Sinus.

The study population consists of adult patients diagnosed with pilonidal sinus disease who undergo pilonidal sinus surgery as part of routine clinical care at participating centers. Eligible patients are enrolled prospectively and followed after surgery. Demographic, anatomical, and surgical characteristics are recorded for observational analysis of postoperative wound outcomes.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

This cohort includes adult patients undergoing pilonidal sinus surgery as part of routine clinical care at participating centers. The study is observational in nature, and no experimental intervention is assigned. Surgical technique, anatomical characteristics including proximity to the anal verge, and morphological stage of the disease are determined by the treating surgeon according to standard practice. Patients are prospectively followed after surgery, and postoperative wound outcomes are recorded for observational analysis.
Other: No intervention (observational study)
This is an observational study. No experimental intervention is assigned. Surgical procedures are performed as part of routine clinical care according to standard practice and are not determined by the study protocol.
Postoperative Wound Dehiscence
Wound dehiscence is defined as partial or complete separation of the surgical wound occurring after pilonidal sinus surgery, as assessed during postoperative follow-up.
Time frame: Within 30 days after surgery
Time to Complete Wound Healing
Time from surgery to complete epithelialization of the surgical wound without discharge or need for additional intervention.
Time frame: Up to 90 days after surgery
