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

Enrollment: 30
Study Start Date: January 2012
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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.

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.
