Clinical Scorecard: Laser Intervention for Pilonidal Disease in Adolescents: A Preliminary Investigation
At a Glance
Category
Detail
Condition
Pilonidal disease (PD) characterized by sinus formation in the natal cleft due to hair penetration and foreign body reaction
Key Mechanisms
Foreign body reaction to broken hair or clogged keratin hair follicles leading to sinus formation
Target Population
Adolescents aged 10–17 years with pilonidal sinus without active infection
Care Setting
Tertiary paediatric surgical hospital outpatient and surgical care
Key Highlights
PD incidence peaks in young people aged 15–30 years with risk factors including male sex, obesity, sedentary lifestyle, hairiness, heredity, and hygiene habits.
Laser therapy (a-PiLaT) was used as a primary treatment in adolescents, involving pit excision and laser ablation of sinus tracts under general anesthesia.
In a series of 17 patients, laser treatment showed a mean operative time of 21.5 minutes, 24% complication rate mostly mild, and 18% recurrence over a mean follow-up of 24.5 months.
Guideline-Based Recommendations
Diagnosis
Clinical diagnosis based on presence of pilonidal pits and sinus in natal cleft in adolescents.
Exclude patients with signs of active inflammation, secondary infection, or abscess formation.
Management
Laser therapy (a-PiLaT) involving pit-picking and laser ablation of sinus tracts is a minimally invasive option.
Preoperative hair removal and antiseptic preparation are essential.
General anesthesia and prone positioning recommended for procedure.
External openings are not closed post-procedure to allow epithelialisation.
Monitoring & Follow-up
Outpatient follow-up at 1 week, 3 weeks, and 3–4 months post-procedure to monitor wound healing and detect recurrence.
Use of Patient and Observer Scar Assessment Scale (POSAS) for scar evaluation.
Risks
Postoperative complications include local infection, wound healing disorders, and prolonged wound secretion.
Recurrence rate observed was 18%, with some patients requiring revision laser treatment or alternative surgery.
Patient & Prescribing Data
Adolescents aged 10–17 years with pilonidal sinus without active infection
Laser therapy is a short-duration procedure (~21.5 min) with outpatient follow-up; complications are mostly mild and manageable; recurrence occurs in a minority but can be treated with revision laser therapy.
Clinical Best Practices
Select patients without active infection or abscess for laser therapy.
Perform hair removal and antiseptic cleaning prior to procedure.
Use pit-picking technique with 1-mm skin margin before laser ablation.
Infiltrate surrounding tissue with saline to prevent skin burns during laser use.
Do not close external openings to facilitate epithelialisation.
Monitor patients closely postoperatively for complications and recurrence.
Manage minor complications conservatively; use antibiotics or drainage if needed.
Consider revision laser treatment for recurrences before more invasive surgery.
