From absorbable to non-absorbable sutures…

This guide explores suture materials, techniques, and surgical applications for improved clinical outcomes.

Surgical sutures are a cornerstone of modern operative medicine. Whether closing incisions or repairing tissue, the type of suture selected directly affects healing, recovery time, and complication risk. For trained surgical professionals, understanding the characteristics of each suture type is critical. This guide covers the primary classifications of sutures, their ideal applications, and key considerations for clinical decision-making.

What Are Surgical Sutures?

Surgical sutures are sterile threads or filaments that hold tissue together after trauma or surgery. By providing temporary mechanical support, sutures enable natural tissue healing, minimize bleeding, and reduce infection risks.

The Role of Sutures in Wound Healing

Proper wound closure supports wound edge approximation, reduces dead space, and lowers the likelihood of wound dehiscence or delayed healing. When chosen appropriately, sutures facilitate optimal cosmetic and functional outcomes while reducing patient morbidity.

Classification: Absorbable vs Non-Absorbable Sutures

Sutures fall into two main categories—absorbable and non-absorbable, depending on whether the body can break down the material over time.

Absorbable Sutures

Absorbable sutures are designed to degrade through enzymatic or hydrolytic processes. They are preferred for internal tissues that heal quickly and don’t require removal.

• Polyglactin 910 (Vicryl): A braided synthetic suture made of glycolide and lactide. Vicryl offers excellent knot security, moderate tissue reactivity, and predictable absorption (complete absorption in 56–70 days).

   

• Polyglycolic Acid (Dexon): A braided absorbable suture with high initial tensile strength. Commonly used in gynecologic and gastrointestinal procedures.

   

• Poliglecaprone 25 (Monocryl): A monofilament absorbable suture made of glycolide and ε-caprolactone. Offers minimal tissue drag and is absorbed within 90–120 days. Frequently used in subcuticular closures and soft tissue approximation.
  

Non-Absorbable Sutures

Non-absorbable sutures retain tensile strength long-term and are used in tissues that require prolonged support.

• Nylon Sutures: Synthetic monofilament or braided sutures with high tensile strength and minimal tissue reactivity. Common in skin closures and microsurgery.

   

• Polyester Sutures: Braided, coated sutures with low elasticity and high durability. Used in cardiovascular and orthopedic applications.

   

• Polypropylene Sutures (Prolene): A non-absorbable monofilament with minimal tissue reactivity. Ideal for vascular and plastic surgery.

   

• Silk Sutures: Braided natural protein-based sutures. Easy to handle but provoke more inflammation than synthetic alternatives. Typically used in mucosal and ophthalmic procedures.
  

Choosing the Right Suture Material

Suture selection should be based on:

• Tissue type (e.g., skin, muscle, fascia, or internal organ)

   

• Healing time expected for the tissue

   

• Need for tensile strength vs rapid absorption

   

• Infection risk

   

• Handling characteristics and knot security
  

For example, absorbable sutures like Vicryl are well-suited for subcutaneous closures, whereas non-absorbable options such as Prolene are better for cardiovascular anastomoses.

Understanding Suture Sizes

Sutures are sized using the United States Pharmacopeia (USP) system, where a higher number of zeros indicates smaller diameters (e.g., 6-0 is finer than 3-0). Smaller sutures are used in delicate procedures (e.g., ophthalmic), while thicker sutures are suitable for orthopedic or abdominal surgeries.

Mastering Suture Techniques and Knots

Beyond material, technique matters. The most commonly used techniques include interrupted, continuous, subcuticular, and mattress sutures. Surgeons must also master surgical knots—such as square, surgeon’s, and granny knots—for reliable wound closure. Incorrect tension or poor technique can lead to ischemia, wound dehiscence, or infection.

Surgical Applications of Sutures

General Surgery

Used to close abdominal incisions, ligate vessels, and repair tissues during procedures such as appendectomies and laparotomies.

Orthopedic Surgery

Sutures are employed in tendon repairs, ligament reconstructions, and fracture-related soft tissue closures.

Cardiovascular Surgery

Critical for vascular anastomoses and heart valve repairs. Prolene and polyester sutures are often preferred for their durability and biocompatibility.

Plastic and Reconstructive Surgery

Suture choice affects scar formation and aesthetic outcomes. Monocryl and nylon are frequently used in facial procedures.

Obstetric and Gynecologic Surgery

Used in cesarean sections, uterine repairs, and pelvic floor surgeries. Absorbable sutures are preferred for internal tissues.

Potential Risks and Complications of Sutures

Although generally safe, sutures carry risks:

• Infection: Especially with braided sutures, which may harbor bacteria.

   

• Allergic reaction: Rare, but possible with natural materials like silk.

   

• Suture granuloma: Chronic inflammatory response to retained suture material.

   

• Tissue ischemia or necrosis: From overtightened sutures.
  

Surgeons should always monitor for signs of complications and choose materials based on patient-specific factors.

FAQs About Surgical Sutures

Are all surgical sutures the same?

No. Sutures vary in composition, absorption rate, strength, and reactivity. Material selection depends on the tissue, healing time, and surgical goals.

How long do absorbable sutures take to dissolve?

Typically, anywhere from 7 days to 3 months depending on the material. Monocryl dissolves faster than Vicryl or Dexon.

Can sutures cause allergic reactions?

Yes, but it’s rare. Silk sutures and other natural fibers have a higher chance of causing local hypersensitivity.

What is the difference between absorbable and non-absorbable sutures?

Absorbable sutures degrade naturally in the body. Non-absorbable sutures must be removed or remain permanently.

How should sutures be cared for postoperatively?

Follow your surgeon’s instructions. Generally, keep the wound clean and dry, and avoid stretching the area.

Final Thoughts

Surgical sutures are far more than simple threads, they’re highly engineered medical devices tailored to specific procedures, tissues, and healing profiles. With advancements in material science and manufacturing, modern sutures continue to reduce complications and enhance patient outcomes.
