Treatment of Pilonidal Abscess After Fall

Initial Assessment and Management

The primary treatment for a pilonidal abscess that develops after a fall is surgical incision and drainage, which should be performed promptly to prevent expansion of the abscess and progression to systemic infection, as recommended by the World Journal of Emergency Surgery 1, 2
Evaluate patients for systemic inflammatory response syndrome (SIRS) signs, including temperature, tachypnea, tachycardia, or abnormal white blood cell count, according to Clinical Infectious Diseases 3, 4
Assess the extent of the abscess through physical examination, looking for pain, swelling, and erythema in the sacrococcygeal region, as suggested by the World Journal of Emergency Surgery 5, 6
The timing of surgical intervention should be based on the presence and severity of sepsis, with emergent drainage indicated for patients with sepsis, immunosuppression, diabetes mellitus, or diffuse cellulitis, as recommended by the World Journal of Emergency Surgery 2, 7

Incision and drainage is the cornerstone of treatment for pilonidal abscess, according to Clinical Infectious Diseases and the World Journal of Emergency Surgery 1, 4
The procedure can be performed under local anesthesia for small abscesses in fit, immunocompetent patients without systemic signs of infection, as suggested by the World Journal of Emergency Surgery 2
For larger or more complex abscesses, or in patients with systemic symptoms, the procedure may require deeper anesthesia and inpatient management, according to the World Journal of Emergency Surgery 5, 8

Systemic antibiotics are generally not required for uncomplicated pilonidal abscesses after adequate surgical drainage, as stated by Clinical Infectious Diseases 4
Antibiotics should be administered if systemic signs of infection, markedly impaired host defenses, significant surrounding cellulitis, or incomplete source control are present, according to Clinical Infectious Diseases and the World Journal of Emergency Surgery 3, 4, 5, 6, 8
When antibiotics are indicated, they should cover common pathogens, including Staphylococcus aureus for simple cases and broad-spectrum coverage for complex cases, as recommended by Clinical Infectious Diseases and the World Journal of Emergency Surgery 3, 5, 8

The use of packing after drainage remains controversial, with some practitioners placing packing for hemostasis and to prevent premature skin closure, while others prefer catheter drainage or no packing, as discussed in the World Journal of Emergency Surgery 2, 7

If the abscess developed after trauma, assess for any foreign bodies or additional tissue damage that might complicate healing, as suggested by the World Journal of Emergency Surgery 8
Patients with diabetes, immunosuppression, or other comorbidities may require more aggressive treatment and closer follow-up, according to the World Journal of Emergency Surgery 2
Imaging is not routinely required but may be helpful in complex cases or when recurrence is an issue, as recommended by the World Journal of Emergency Surgery 1
