Drained Abscesses Should NOT Be Closed with Glue or Sutures
After draining an abscess, the wound should be left open to heal by secondary intention—do not close it with tissue glue or sutures. This is the standard of care supported by major infectious disease guidelines 1, 2.
The Evidence-Based Approach
Primary Treatment: Incision, Drainage, and Open Healing
The most important therapy for an abscess is to open the incision, evacuate infected material, and allow healing by secondary intention 1. This fundamental principle applies to simple cutaneous abscesses and is emphasized across multiple guidelines:
- For simple superficial abscesses: Incision and drainage alone is sufficient, with no need for antibiotics when induration and erythema are limited to the abscess area 2
- The wound must remain open to allow continued drainage and prevent reaccumulation of purulent material
- Antibiotics are unnecessary when there is <5 cm of surrounding erythema, temperature <38.5°C, WBC <12,000 cells/µL, and pulse <100 beats/minute 1
Why Not Close the Wound?
Closing an abscess cavity after drainage contradicts the basic principle of abscess management—you need ongoing drainage. The infected cavity must granulate from the base upward to prevent premature skin closure that would trap residual bacteria and lead to recurrence.
The Nuance: Primary Closure Research vs. Guideline Recommendations
There is an important disconnect to address: Research studies suggest primary closure may work in select cases 3, 4, showing faster healing (7.8 vs. 15 days) with similar recurrence rates. However, these studies have critical limitations:
- Most involved anorectal abscesses drained by surgeons in operating rooms under general anesthesia 3, 4
- They used adjunctive antibiotics and sometimes closed suction drainage 3
- The systematic review acknowledges these were not typical emergency department presentations 4
- No major guideline recommends routine primary closure for standard cutaneous abscesses 1, 2
Packing Considerations
Even the question of packing (not closure) remains debated. Recent evidence shows no significant difference in recurrence whether you pack or don't pack the cavity 5, though avoiding packing may reduce post-operative pain and cost. But packing is fundamentally different from closing—packing maintains an open wound.
When Antibiotics ARE Needed (But Still Don't Close)
Add antibiotics if 1:
- Temperature >38.5°C or heart rate >110 beats/minute
- Erythema extending >5 cm beyond wound margins
- Immunocompromised patients
- Incomplete source control
- Significant surrounding cellulitis 2
Even with antibiotics, the wound remains open.
Common Pitfalls to Avoid
- Don't confuse surgical wound closure with abscess management: The research on tissue glue 6 and fibrin sealant 7 applies to clean surgical incisions (like circumcisions), not infected abscess cavities
- Don't be tempted by faster healing claims: Primary closure studies involved highly selected patients in controlled settings, not typical office-based abscess drainage
- Don't close complex abscesses: Perianal, perirectal, and injection drug use-related abscesses especially require open drainage 2
The Bottom Line Algorithm
- Drain the abscess completely
- Leave the wound open for secondary intention healing
- Consider packing only if cavity >5 cm (though evidence is mixed) 8
- Add antibiotics only if systemic signs present or high-risk features
- Arrange follow-up for wound checks and dressing changes
The tissue glue and suture closure techniques mentioned in your question simply do not apply to abscess management in standard clinical practice.
