Do Vicryl Sutures Dissolve? A Look at Absorbable Sutures

Vicryl sutures, also known as polyglactin 910, are a common type of absorbable suture used in surgery. But do they actually dissolve, and if so, how? This article will delve into the fascinating world of absorbable sutures, explaining how Vicryl sutures work and why they are a popular choice for many surgical procedures.

Understanding Absorbable Sutures

Absorbable sutures are designed to gradually break down and be absorbed by the body over time, eliminating the need for suture removal. This is a significant advantage over non-absorbable sutures, which require a separate procedure for removal.

How Vicryl Sutures Dissolve

Vicryl sutures are made from a synthetic material called polyglactin 910, which is a type of polyester. Unlike natural materials like catgut, which are also absorbable, Vicryl sutures are not digested by enzymes in the body. Instead, they undergo a process called hydrolysis.

• Hydrolysis: In this process, water molecules interact with the polyester chains of the suture material, causing them to break down into smaller fragments. These fragments are then absorbed by the body's immune system.

The Time Frame for Absorption

The time it takes for Vicryl sutures to fully dissolve depends on the suture's size and the location of the surgical site. However, Vicryl sutures are typically designed to be absorbed within 56 to 70 days.

Why Vicryl Sutures are Popular

Vicryl sutures offer several advantages over other types of sutures:

• Convenience: The elimination of suture removal procedures is a major advantage for both the patient and the surgeon.
• Reduced Risk of Infection: Since the sutures dissolve over time, the risk of infection associated with a foreign object in the body is reduced.
• Versatility: Vicryl sutures are suitable for a wide range of surgical procedures, including wound closure, internal tissue repair, and ligating blood vessels.

Limitations of Vicryl Sutures

While Vicryl sutures offer many benefits, they are not suitable for all surgical applications. Some limitations include:

• Loss of Strength: Vicryl sutures gradually lose their strength over time. This may be a concern in areas where the sutures need to hold tissue together for an extended period.
• Tissue Reaction: Some patients may experience a mild inflammatory response at the suture site, though this is generally temporary and resolves on its own.

Alternatives to Vicryl Sutures

If Vicryl sutures are not appropriate for a particular procedure, there are other options available. For example:

• Monocryl (poliglecaprone 25): Another absorbable suture that offers faster absorption than Vicryl, typically dissolving within 90 to 120 days.
• PDS (polydioxanone): An absorbable suture that provides longer-lasting strength than Vicryl, with absorption taking 180 to 210 days.

Conclusion

Vicryl sutures are a reliable and convenient option for many surgical procedures. Their ability to gradually dissolve eliminates the need for suture removal, reducing the risk of infection and providing a more comfortable patient experience. While Vicryl sutures have their limitations, they remain a popular choice in many surgical specialties.
