Surgical sutures are medical devices used to hold body tissues together after an injury or surgery. They are essential for wound closure, promoting optimal healing and minimizing infection risks. Sutures are broadly classified into two categories: absorbable sutures and non-absorbable sutures.

What Are Surgical Sutures?
Before jumping into comparisons, let’s clarify the basics. According to Siny Medical’s Guide on Surgical Sutures, sutures are sterile threads used to close wounds and surgical incisions. They hold tissues together while the body naturally heals.
These threads can be made of synthetic or natural materials, and their behavior inside the body determines if they’re absorbable or non-absorbable.
For a more detailed overview, check out Siny’s blog on Types and Uses of Surgical Sutures.
What Are Absorbable Sutures?
Absorbable sutures are designed to be broken down by the body over time. They are made from materials that degrade naturally through enzymatic or hydrolytic processes, eliminating the need for removal. Absorbable sutures are often used for internal tissues, where removing sutures would be difficult or traumatic for the patient.
Common types of absorbable sutures include catgut, polyglycolic acid (PGA), polydioxanone (PDO), and polyglactin. Each type has a specific absorption rate and tensile strength, making them suitable for different surgical applications. For a detailed look at absorbable suture products, see Absorbable Surgical Sutures and Absorbable Medical Surgical Suture.
Benefits of Absorbable Sutures:
- No need for suture removal, enhancing patient comfort and convenience.
- Reduced tissue reaction and inflammation compared to some non-absorbable materials.
- Customized absorption rates for different healing needs.
- Facilitate wound healing by providing temporary support until tissue regains strength.
- Versatility for use in various internal and external wounds.
- Lower risk of infection due to reduced foreign body presence1.

What Are Non-Absorbable Suture?
Non-absorbable suture are made from materials that are not broken down by the body. They remain intact at the wound site unless they are manually removed. These sutures are ideal for situations where long-term tissue support is necessary, or where the wound is subject to prolonged stress and movement.
Manufacturers use natural materials like silk or synthetic ones such as nylon, polyester, polypropylene, and stainless steel to make non-absorbable suture. Surgeons commonly use these sutures for skin closures, cardiovascular surgeries, orthopedic procedures, and other situations that require permanent or long-term support.

Key Differences: Absorbable vs. Non-Absorbable Suture
| Feature | Absorbable Sutures | Non-Absorbable Sutures |
|---|---|---|
| Degradation | Naturally breaks down | Does not degrade |
| Removal Needed? | No (unless complications arise) | Yes (for external use) |
| Primary Use | Internal tissues, mucous membranes | Skin, tendons, vascular repairs |
| Tensile Strength | Temporary (weeks to months) | Long-term (years) |
| Infection Risk | Lower (fewer follow-ups) | Higher (if left in place too long) |

Factors Influencing Suture Choice in Surgery
Surgeons consider several factors before selecting the right suture type:
1. Nature of the Tissue:
Delicate tissues like intestinal walls need sutures that don’t stay too long. Absorbables work well here.
2. Healing Time Required:
Non-absorbable suture better manage longer-healing wounds or tension-heavy closures.
3. Risk of Infection:
Absorbables reduce the risk of retained suture-related infections since they dissolve.
4. Cosmetic Concerns:
Surgeons often prefer non-absorbable sutures for visible skin closures because they provide superior tensile strength and allow better control over scarring.

Summary
Choosing between absorbable and non-absorbable sutures depends on the wound type, location, and required healing duration. Absorbable sutures are ideal for internal tissues, while non-absorbable suture provide long-term support for skin and high-tension repairs.

FAQ
What are non-absorbable sutures?
Surgeons use non-absorbable sutures—sterile surgical threads made from materials the body cannot break down. These sutures stay in place until medical professionals remove them or leave them permanently based on the surgical need. Explore Non-Absorbable Sutures for more details.
When are non-absorbable sutures preferred?
Medical professionals prefer non-absorbable sutures for procedures requiring long-term tissue support, including skin closures, cardiovascular repairs, and orthopedic surgeries.
Are non-absorbable suture safe?
Yes, when used appropriately, they are safe and effective. However, they may increase the risk of infection or tissue reaction if not managed properly.
How are non-absorbable sutures removed?
A healthcare professional typically performs the removal using sterile instruments after the wound has healed sufficiently.
What materials are used in non-absorbable sutures?
Common materials include silk, nylon, polyester, polypropylene, and stainless steel.
Can non-absorbable sutures cause allergic reactions?
While rare, some patients may experience mild tissue reactions or allergies, especially with natural fibers like silk or synthetic materials like polyester.
Is there a difference in scarring between absorbable and non-absorbable sutures?
Clinical studies show no significant difference in scar quality or patient satisfaction between the two types for most procedures.
