Sutures vs. Staplers for Skin Closure
For skin and soft-tissue closure, continuous subcuticular sutures using absorbable materials (4-0 poliglecaprone or polyglactin) should be preferred over surgical staplers to reduce wound dehiscence and surgical site infections. 1
When to Choose Sutures Over Staplers
The evidence strongly favors sutures in most surgical scenarios:
Sutures Are Superior For:
Reducing wound dehiscence: Continuous subcuticular sutures demonstrate an 92% reduction in superficial wound dehiscence compared to interrupted sutures (RR 0.08; 95% CI 0.02-0.35) 1
Preventing surgical site infections: In hepato-pancreatobiliary surgery, subcuticular continuous sutures showed significantly lower SSI rates (1.8%) compared to stapling (10.0%, P < 0.01) 1. Recent vascular surgery data confirms staples carry 57% higher odds of SSI compared to sutures 2
Lower reoperation rates: Staples are associated with 30% higher odds of return to operating room 2
Reduced hospital stays: Staples increase odds of prolonged length of stay >7 days by 30% 2
Staplers May Be Considered For:
- Scalp wounds: Limited evidence suggests staples may have a role in scalp closure where cosmesis is less critical 3
- Time-critical situations: While staples are faster, this convenience comes at the cost of increased complications 2
Recommended Suture Types and Techniques
Optimal Suture Material:
Use 4-0 absorbable synthetic sutures 1:
- Poliglecaprone (Monocryl)
- Polyglactin (Vicryl)
These materials retain 50-75% of tensile strength after 1 week in situ, providing extended wound support that prevents dehiscence 1
Preferred Technique:
Continuous subcuticular closure is superior to interrupted sutures 1:
- Provides better seal against bacterial invasion 1
- No suture removal required (patient convenience)
- Lower dehiscence rates
- Equivalent SSI rates to interrupted sutures
Critical technical point: Avoid pulling continuous sutures too tightly, as this can strangulate wound edges and compromise healing 1
Interrupted Sutures:
When using interrupted technique:
- Subcuticular interrupted sutures are preferable to transcutaneous sutures 3
- Non-absorbable transcutaneous sutures require removal at 7-9 days 1
- Consider for wounds under high tension where individual suture adjustment is needed
Common Pitfalls to Avoid
Don't add steri-strips routinely: No evidence supports improved outcomes with adhesive strips added to subcuticular sutures 1. They don't reduce SSI, improve cosmesis, or decrease scar width.
Avoid tissue adhesives for high-tension wounds: Low-quality evidence suggests sutures are significantly better than tissue adhesives for reducing wound dehiscence (RR 3.35; 95% CI 1.53-7.33) 1
Don't choose staplers for convenience alone: While faster, staplers consistently show worse outcomes in terms of infection, dehiscence, and patient satisfaction 2, 4
Avoid wound packing after closure: One study found packing causes more pain without improving healing compared to simple sterile gauze coverage 5
Evidence Quality Considerations
The guideline recommendations carry Grade 1B evidence (strong recommendation, moderate-quality evidence) 1. While most evidence comes from abdominal and groin operations, the principles apply broadly to surgical wound closure. The evidence base includes Cochrane meta-analyses and multi-institutional studies, though high-quality RCTs specific to all surgical contexts remain limited 1.
The most recent high-quality evidence from 2024 vascular surgery data strongly reinforces that meticulous suture closure should be preferred over staples despite the time investment 2.
