Comparison of the three surgical flap techniques in pilonidal sinus surgery.

We aimed to study the efficacy of three surgical flap techniques in pilonidal surgery. Pilonidal disease is characterized by chronic inflammation and infection in the sacrococcygeal region. Complications and recurrence are common after treatment and optimal treatment for the disease has not been established yet. We enrolled a total of 401 patients in this study. Patients have been treated with Karydakis (n = 113), modified Limberg (n = 179), or Limberg (n = 109) flap techniques. Mean off-work period, time to walk without pain, time to sit on the toilet, time to take the drainage catheter off, maceration rates, recurrence, and hypoesthesia rates were significantly better in the modified Limberg group. In conclusion, we showed the modified Limberg technique is superior than both Limberg and Karydakis techniques.
