Can it be treated with medicines alone ?

In the earliest stages, it may resolve with antibiotics.
But mainly it is a surgical problem.
Treatment depends on type of presentation to doctor


A) Pilonidal abscess

B) Pilonidal Sinus / Cyst

Excision & Primary suturing

Karydakis Flap

Sinus Laser Therapy (SiLaT)

Video assisted Ablation of Pilonidal Sinus

Endoscopic Pilonidal Sinus treatment (EPSiT) – May need repeated sessions

The current research evidence supports off-midline technique due to 

  1. Low recurrence rates 
  2. Avoiding open wound & hence faster healing

Here are benefits;-

  1. Fast Healing due to closed wound
  2. Short Hospital Stay
  3. Leat recurrence rates
  4. Low Complications
  5. Better Patient Satisfaction
  6. Early return to Work
  7. Minimal Dressing required

It is a good option with its own benefits & concerns.

  • Avoid weight bearing for 2-3 days after limberg flap surgery to avoid skin necrosis & ensure proper blood supply to new skin coverage 
  • Low fiber diet to avoid Stool contamination & decrease chance of infection
  • Stop Smoking for better healing & Avoid Necrosis of Flap
  • Laser Depilation is recommended instead of shaving hair.
  • Get Biopsy report of removed part check with your surgeon

Recurrence rates of 3 to 18 percent depending on the type of disease & Procedure.

Limberg flap has shown very good success rates with least recurrences as compared to Laser Treatment of Pilonidal sinus.

In the best hands, recurrence rates are much lower.

Infection ( 2 – 5 % )

Recurrence ( 7 -18 % )

Bleeding ( 1 – 2 % )

Flap necrosis ( 1 – 5 %)

  • Complication & Recurrence rates should be low
  • Acceptable treatment as per patients comfort level & findings
