Sutures can basically be divided into two types one is those which are absorbable and which will break down harmlessly in the body over the time with no intervention, and the another one are those which are non-absorbable and that must be removed manually if they are not left open-endedly. The type of the suturesare being used are basically varies on the operation, with the major criteria of being in the demands of the location and the environment and it depends on the discretion and the professional experience of the Surgeons. Sutures are placed internally and would require to re-opening if they were need to be removed. Sutures which are lie on the exterior of the body can be removed within a minutes of time, and there is no need to re-open the wound. As a result, the absorbable sutures are mostly used internally and the non-absorbable used externally. The sutures which are absorbable includesPolyglactinsuture, Polyglycolic Acid sutures, Poliglecapronesuture and the Polydioxanone sutures and the sutures which are non-absorbable sutures includes Polypropylene sutures, Polyester, poylamide,PVDF, silk and the stainless steel sutures.Let’s try to know more about absorbable and non-absorbable stutures:
Absorbable Stuture
- Polyglycolic Acid suture- It is an absorbable multifilament surgical suture with the synthetic coating, with the greater tensile strength, having a longer period of absorption and which results in the very little inflammatory reaction. Polyglycolic suture is degraded by the Chemical Hydrolysis, and it is absorbed and metabolized easily by the human body. It is having some great features such as High-performance, optimum effectiveness and the strength.
- Polyglactin suture- It is the synthetic absorbable surgical suture, which indicatesthe procedure which require to approach the soft tissues for a period of around 56 to 70 days. It allows an exact placing of the knot, and it tends less to plaster the tissues.
- Poliglecaprone suture- It is an absorbable, synthetic, and monofilament surgical suture which is composed of a copolymer of glycoside and the epsilon caprolactone.
- Polydioxanone suture- It is a sterile monofilament synthetic absorbable suture which is composed of the polyester, or poly (p-dioxanone). It provides the support to the wound for a longer period as it is compared to other synthetic absorbable sutures. It also offers a far superior strength to the tensile.
If we talk about non-absorbable stuture then the first thing comes in the mind is non-absorbable polypropylene suture which is also synthetic and monofilament. It is basically indicated for the skin closure and for the general soft tissue approximation and ligation. The advantages of this includes minimal tissue reactivity and the durability and the Disadvantages of it include the fragility, high plasticity, the high expense, and the difficulty of use as compared to the standard nylon sutures. It is made up of an isotactic crystalline stereoisomer of the polypropylene. A polypropylene mesh is also comes under the name ofProlene asit is used for the repairing hernias and the other injuries to the fascia.It is commonly is used in both the human and the veterinary medicine for the skin closure.
