Factors Affecting Wound Dehiscence in Pilonidal Sinus Surgery (ORIPIS)

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)

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.

Inclusion Criteria:

• Adult patients (≥18 years of age)
• Diagnosis of pilonidal sinus disease
• Patients undergoing pilonidal sinus surgery as part of routine clinical care
• Ability to provide informed consent

Exclusion Criteria:

• Patients undergoing emergency surgery
• Previous pilonidal sinus surgery at the same site
• Inability to complete postoperative follow-up
