Treatment Options at Shri Manmukund Hospital

Conservative Management

For early asymptomatic cases: hygiene, hair removal in the area, avoiding prolonged sitting where possible.

Incision and Drainage

For acute abscess. Immediate relief. Usually not definitive.

Laser Pilonidal Sinus Treatment (SiLaC)

Modern minimally invasive approach using a laser fibre through the sinus tract. Sphincter-preserving equivalent for pilonidal disease. Advantages: Small incision, faster recovery, lower recurrence in appropriate cases.

Ksharsutra

Classical Ayurvedic approach adapted for pilonidal sinus. Suitable for select cases, particularly recurrent ones.

Conventional Surgery

Various techniques: wide excision with primary closure, excision with flap reconstruction (Karydakis, Limberg), or open granulation. Choice depends on the disease extent.

Recovery

Varies by treatment. Laser: 1 to 2 weeks. Surgical excision: 2 to 6 weeks depending on technique and healing.

Prevention of Recurrence

  • Regular hygiene of the area
  • Hair removal in the natal cleft (shaving, laser hair removal)
  • Weight management
  • Avoiding prolonged sitting where possible
