6-0 Fast-Absorbing Plain Gut Sutures for Subcutaneous Closure
6-0 fast-absorbing plain gut sutures used for subcutaneous closure will dissolve on their own and do not require removal. 1
Characteristics of Fast-Absorbing Plain Gut Sutures
Fast-absorbing plain gut sutures are designed to dissolve naturally within the body through a process of enzymatic degradation. When used for subcutaneous closure:
- They typically dissolve within 5-7 days post-procedure
- They maintain approximately 50-75% of their tensile strength after 1 week in situ 2
- They are completely absorbed by the body's natural processes
- No suture removal appointment is necessary
Clinical Evidence Supporting Use
Fast-absorbing gut sutures have gained popularity in dermatologic and plastic surgery due to several advantages:
- Low tissue reactivity
- Rapid absorption rate
- Elimination of suture removal visits 3
- Comparable complication rates to other suture types
In a prospective study of 800 consecutive blepharoplasties, running 6-0 fast-absorbing gut sutures resulted in the lowest rates of complications and revisions compared to other closure techniques. Only 2% of patients presented with milia, and there were no scar revisions needed 1.
Comparison to Other Suture Options
While fast-absorbing gut sutures offer convenience through self-dissolution, it's worth noting:
- Polypropylene (non-absorbable) sutures may provide slightly better cosmetic outcomes in some studies 4
- The difference in wound dehiscence between fast-absorbing gut and other suture types is generally not statistically significant 5
- Fast-absorbing gut sutures are less likely to experience wound dehiscence than tissue adhesives 3
Best Practices for Subcutaneous Closure
When using 6-0 fast-absorbing plain gut for subcutaneous closure:
- A continuous suturing technique is recommended over interrupted sutures for optimal wound healing 2
- Ensure proper tension to avoid tissue necrosis or poor scarring 6
- Consider the "small bite" technique (5mm from wound edge and 5mm between stitches) for optimal healing 6
Conclusion
For subcutaneous closure with 6-0 fast-absorbing plain gut sutures, no suture removal is required as these sutures will naturally dissolve within 5-7 days. This provides the convenience of avoiding a follow-up visit for suture removal while maintaining acceptable wound healing outcomes.
