Patients and Methods: We has collected 10 patients who has undergone pilonidal sinus excision and wound reconstruction from March 2013 to November 2017. We used the Nelaton tube for identification of subcutaneous tract and injected the blue dye into the whole tract. When excision was arranged, we could not only excise the whole tract without damage to the sinus wall but also have guideline to avoid removing excessive healthy tissue. After excision, bilateral advance flap was used for wound closured under tension free.
Results: The average follow up time was 24.6 months. No sinus recurrence was found during our follow up. Post-operative care included local wound care, antibiotics treatment, and absolute prone position were applied for 2 weeks. No remarkable post-operative complications were found. All the patients achieved satisfactory results.
Conclusion: The subcutaneous guide-wide and intra-lesional dyes for radical excision of pilonidal sinus and wound reconstruction can reduce the recurrent rate without notable morbidity.
