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

Condition or disease Intervention/treatment Phase
Pilonidal Sinus Procedure: Pilonidal sinus excision Not Applicable

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.

Arm Intervention/treatment
Experimental: Methylene Blue
The effect of methylene blue dye in detection and total excision of pilonidal sinus will be studied histopathologically.
Procedure: Pilonidal 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.

Primary Outcome Measures :
  1. Histopathologic detection of any evidence of pilonidal sinus disease in the cavity excision material not dyed by methylene blue [ Time Frame: 3 months ]
