Surgical stitches, also known as sutures, are common for closing wounds after surgery or injury. They aid in the healing process by holding the edges of a wound together. There are various types of stitches, each designed for specific medical needs and circumstances. Dissolvable stitches stand out due to their unique ability to be absorbed by the body over time, eliminating the need for removal.

Dissolvable stitches are made from materials the body can naturally break down and absorb. These stitches are particularly advantageous in areas that are difficult to access for removal or for patients who may have difficulty returning for follow-up appointments. Knowing about dissolvable stitches is crucial for post-surgical care. It helps patients understand how to care for their wounds, recognize the signs of routine healing versus complications, and ensure a smooth recovery process. Proper knowledge and care can significantly enhance the healing experience and reduce the risk of post-operative issues.

What Are Dissolvable Stitches?

Dissolvable stitches, also known as absorbable or resorbable sutures, are a type of surgical stitching material designed to be broken down by the body over time, eliminating the need for removal. These stitches are commonly used for internal tissues and organs and in pediatric patients or others who might have difficulty attending follow-up appointments for stitch removal. The primary purpose of dissolvable stitches is to hold wound edges together during the critical initial phases of healing, ensuring proper tissue alignment and promoting efficient healing.

In contrast to non-dissolvable stitches, which a healthcare professional must manually remove once the wound has sufficiently healed, dissolvable stitches naturally degrade within the body. This degradation process is typically smooth and predictable, reducing the risk of complications associated with stitch removal.

What are dissolvable stitches made of? Dissolvable stitches are made from various biodegradable materials engineered to break down safely within the body. Common materials include polyglycolic acid (PGA), polylactic acid (PLA), and other synthetic polymers. These materials are chosen for their strength, flexibility, and predictable absorption rates. Polyglycolic acid, for example, is a synthetic polymer that hydrolyzes in the body, gradually losing its tensile strength and breaking down into harmless by-products that are absorbed and excreted. Polylactic acid works similarly, providing initial wound support before being metabolized by the body.

The biodegradable properties of dissolvable stitches differentiate them significantly from traditional non-dissolvable stitches. Non-dissolvable stitches are typically made from materials such as nylon, silk, or polypropylene, which are not absorbed by the body and require manual removal once the wound has healed sufficiently. The choice between dissolvable and non-dissolvable stitches often depends on the location of the wound, the type of tissue being sutured, the patient's overall health, and the surgeon's preference.

Dissolvable stitches offer numerous benefits, including reduced patient anxiety over stitch removal, decreased need for follow-up visits, and minimized disruption to healing tissues. Their ability to be absorbed naturally by the body makes them a convenient and effective option for many surgical procedures and wound closures.

How Long Do Dissolvable Stitches Last?

Dissolvable stitches are designed to be absorbed by the body over a specific period, gradually losing their strength and support as the wound heals. The duration for which dissolvable stitches last can vary significantly depending on the type of material used, the location of the wound, the nature of the surgery, and the patient’s overall health. Understanding the general timeline and the factors influencing the duration is crucial for effective wound management and optimal healing.

How long do dissolvable stitches last? Here’s a breakdown of the typical duration for various materials:

Polyglycolic Acid (PGA): These stitches usually dissolve within 60 to 90 days. They are commonly used for soft tissue surgeries and are known for their high tensile strength and rapid absorption rate.

Polylactic Acid (PLA): Stitches made from PLA generally dissolve within 90 to 120 days. PLA is often used for surgeries requiring a slower degradation rate and balancing strength and absorption.

Catgut: Derived from the intestines of animals, catgut stitches dissolve within 10 to 21 days. Although less commonly used today due to the availability of synthetic alternatives, they are still used in specific surgical contexts.

Polyglactin 910 (Vicryl): These stitches typically dissolve within 56 to 70 days. Vicryl is widely used in internal and external tissue closures due to its strength and versatility.

Polydioxanone (PDS): Known for its slow absorption rate, PDS stitches can last 180 to 210 days. They are ideal for deep tissue closures where prolonged support is necessary.

Biological Mechanisms of Absorption

The body absorbs dissolvable stitches through a combination of hydrolysis and enzymatic degradation. In hydrolysis, water molecules break down the suture material's chemical bonds, leading to its gradual disintegration. Enzymatic degradation involves the body’s enzymes attacking the suture material, breaking it down into smaller components that can be metabolized and eliminated.

Hydrolysis: Synthetic materials like polyglycolic acid (PGA) and polylactic acid (PLA) primarily dissolve through hydrolysis. This predictable and consistent process allows for reliable timelines for suture absorption.

Enzymatic Degradation: Natural materials such as catgut are absorbed through enzymatic action. This process can vary based on the individual's enzyme levels and immune response, making the absorption rate less predictable than that of synthetic materials.

Average Timeframes for Different Stitch Types

The average timeframes for dissolvable stitches to dissolve vary based on the material:

Polyglycolic Acid (PGA): Typically dissolves within 60 to 90 days.

Polylactic Acid (PLA): Generally dissolves within 90 to 120 days.

Catgut: Dissolves within 10 to 21 days.

Polyglactin 910 (Vicryl): Dissolves within 56 to 70 days.

Polydioxanone (PDS): Dissolves within 180 to 210 days.

Signs that Stitches Are Dissolving and What to Expect

As dissolvable stitches break down, patients may notice several signs indicating the process:

Decreased Tightness: The wound may feel less tight as the stitches lose strength.

Absorption: In some cases, small fragments of the suture material may be visible on the wound surface or in dressings as they break down.

Itching or Discomfort: Mild itching or discomfort is expected as the stitches dissolve, and the wound continues to heal.

No Need for Removal: Unlike non-dissolvable stitches that gradually disappear, there’s no need for a follow-up appointment to remove them.

Patients should monitor their wounds for any signs of complications, such as increased redness, swelling, or discharge, which could indicate an infection or adverse reaction. As advised by healthcare professionals, proper wound care is crucial during this period to ensure optimal healing.

Several factors influence how long dissolvable stitches last:

Location of the Wound: Stitches in high-movement areas, such as joints or areas subject to friction, may dissolve faster due to the constant stress and movement. In contrast, stitches in less mobile areas may last longer.

Type of Surgery: The nature of the surgery plays a crucial role. For instance, stitches used in gastrointestinal surgeries may need to remain in place longer than those used in superficial skin closures.

Patient’s Health: The patient’s health status, including age, nutrition, and the presence of chronic conditions like diabetes or autoimmune diseases, can affect the healing process and the duration of stitch absorption. For example, patients with compromised immune systems may experience slower healing, potentially affecting the longevity of dissolvable stitches.

Understanding these variables helps healthcare providers tailor dissolvable stitches to each patient’s needs, ensuring that the stitches provide optimal support throughout the healing process.
