Dissolvable stitches, also known as absorbable sutures, are a type of suture that breaks down and absorbs by the body over time. They are commonly used in various medical procedures, including surgeries, wound closures, and skin repairs. The concept of dissolvable stitches has been around for decades, with the first absorbable sutures made from catgut, a type of natural fiber derived from animal intestines. Today, dissolvable stitches are made from a variety of materials, including synthetic polymers and natural substances.
The use of dissolvable stitches has become increasingly popular due to their convenience and reduced risk of complications. Unlike traditional sutures, which require removal after healing, dissolvable stitches eliminate the need for a follow-up appointment, making them a more patient-friendly option. Additionally, dissolvable stitches reduce the risk of infection and tissue damage associated with suture removal.
How Dissolvable Stitches Work
Dissolvable stitches work by using materials that can be broken down by the body's natural processes. These materials are designed to be strong enough to hold tissue together during the healing process but weak enough to be degraded and absorbed by the body over time. The degradation process typically occurs through hydrolysis, a chemical reaction in which the body's fluids break down the suture material.
The rate of degradation depends on various factors, including the type of material used, the size of the suture, and the location of the suture in the body. Some dissolvable stitches may take several weeks or even months to fully degrade, while others may break down in a matter of days.
Types of Dissolvable Stitches
There are several types of dissolvable stitches available, each with its own unique characteristics and properties. Some of the most common types of dissolvable stitches include:
- Vicryl (polyglactin 910): A synthetic suture made from a copolymer of glycolic acid and lactic acid. Vicryl sutures are commonly used in general surgery, orthopedic surgery, and plastic surgery.
- Monocryl (poliglecaprone 25): A synthetic suture made from a copolymer of caprolactone and glycolic acid. Monocryl sutures are commonly used in skin closures, wound repairs, and surgical procedures.
- Dexon (polyglycolic acid): A synthetic suture made from a polymer of glycolic acid. Dexon sutures are commonly used in general surgery, gynecologic surgery, and urologic surgery.
- Catgut: A natural suture made from animal intestines. Catgut sutures are commonly used in general surgery, orthopedic surgery, and plastic surgery.
| Type of Suture | Material | Degradation Time |
|---|---|---|
| Vicryl | Polyglactin 910 | 50-70 days |
| Monocryl | Poliglecaprone 25 | 90-120 days |
| Dexon | Polyglycolic acid | 30-60 days |
| Catgut | Natural fibers | 10-20 days |

Advantages and Disadvantages of Dissolvable Stitches
Dissolvable stitches have several advantages, including reduced risk of infection, reduced risk of tissue damage, and elimination of the need for suture removal. However, they also have some disadvantages, including potential tissue reaction, limited strength, and variable degradation rates.
Potential Tissue Reaction
Some patients may experience a tissue reaction to dissolvable stitches, including inflammation, redness, and swelling. This reaction is typically mild and resolves on its own, but in some cases, it may require medical attention.
Limited Strength
Dissolvable stitches may not provide the same level of strength as traditional sutures, which can be a concern in high-tension areas or areas subject to significant stress.
Variable Degradation Rates
The degradation rate of dissolvable stitches can vary depending on various factors, including the type of material used, the size of the suture, and the location of the suture in the body. This variability can make it challenging to predict when the sutures will fully degrade.
Conclusion
In conclusion, dissolvable stitches are a convenient and effective option for wound closure and tissue repair. Their ability to degrade and absorb by the body reduces the risk of complications and promotes faster healing. While they have some disadvantages, including potential tissue reaction, limited strength, and variable degradation rates, the benefits of dissolvable stitches make them a popular choice among medical professionals.
