Brief summary

Methylene bleu use in pilonidal sinus surgery is not an effective guidance as expected.

Detailed description

To study the potential benefits of intraoperative methylene blue use in pilonidal sinus surgery in detecting the borders of the disease, the histopathologic correlation between the specimen dyed by methylene blue and also the cavity excision specimen not dyed by methylene blue was investigated. The branches that distinctly exceeded the planned dyed excision borders will tried to be detected histopathologically, if any.

Interventions

PROCEDUREPilonidal sinus excision

The dyed portion of the excised pilonidal sinus and non-dyed cavity excision specimen will be studied histopathologically to detect any remnant of pilonidal sinus.
