NonAbsorbable Suture
Nonabsorbable suture has been used for at least 4000 years. Sutures has different types, including absorbable and non absorbable. Suture is a medical material used for closing wounds, stopping bleeding and fusing the tissue during surgical operations.
In General Surgery Use Of Sutures
Bleeding wounds, surgical incisions are closed with suture.
It is very important to use suture materials that will serve the purpose in order to obtain a successful result from the surgical operation and to close the wound and incisions with the least possible scar.
Absorbable sutures are very useful due to their properties compared to non absorbable sutures. This situation causes absorbable suture to have a wide range of use. Such as;
- Gynecology
- General surgery
- Ophthalmic surgery
- Urology
- Gastrointestinal surgery
- Plastic surgery
- Veterinary medicine
Use Of Non Absorbable Sutures In Gynecology
Nonabsorbable sutures are the materials that absorbed by body hydrolysis or enzymatically. Absorbable suture performs its function and is absorbed over time. After the absorption time is completed, there will not be any foreign object left in the body. Thats’ why nonabsorbable suture in gynecology and such as other surgeries cause less tissue reaction. It is produced in various colors to increase its visibility during application and surgery. Absorbable sutures are produced using completely natural colorants. Synthetic polymer-structured suture materials with longer tension, higher knot reliability and greater ease of use are among the most preferred today.
In Ophthalmic Surgery Use Of Absorbable Sutures
Suture is the material used at the end of the tissue integrity deteriorated during the surgical procedure and to control the incoming bleeding. The strength of the suture: It is the “breaking force” required to rupture on a section. Sutures are has high knot security and they are strong and soft,flexible materials. Sutures can have to types, nonabsorable suture and absorable sutures. Nonabsorable suture types are one of the most used materials in a ophthalmic surgery. The absorption method is absorbable for hydrolysis / water and when there is moisture, it is absorbent. The risk of tissue reaction is very low and there is a predictable absorption time. Discharge troopers used is a factor that prepares troop techniques and troopers. Different types of operations are performed for each type.
About Non Absorbable Sutures
During the surgical procedure, the materials used to prevent the disintegration of the damaged tissue as a result of various applications and to control bleeding conditions that may occur are called sutures. It has passed into our language from the French word “souture”. Suture, which has been used in surgical procedures for over 4,000 years, was used in ancient civilizations by obtaining the hair of horsetail. Today, in line with technological developments, nonabsorbable suture materials are produced using biocompatible materials and have a much more ergonomic structure. The ideal suture should provide uniform tensile strength, hold the wound securely during the healing process, and have minimal dimensions for easier absorption. In addition, it should be predictable, easy to use, produce minimal reaction and be knotted securely.
Using Non Absorbable Suture
The type of nonabsorbable suture chosen depends greatly on the clinical scenario. For example, as a rough guide, massive closure of a midline laparotomy (abdominal cavity) may require the use of PDS sutures, a vascular anastomosis (vessel connection), possibly the use of a prolene suture, the use of a hand-sewn intestinal anastomosis vicryl suture, and the use of a silk suture to provide a drain. Nonabsorbable sutureused to provide long-term tissue support and are surrounded by inflammatory processes of the body until they are manually removed if necessary. It can be used in the surgery of slowly functioning tissues such as fascia and tendons. It is also preferred in operations for closure of the abdominal wall or vascular anastomoses.
Types Of Non Absorbable Sutures
- Nylon (Ethilon, Dermalon, Nylene, Norulon): It is an inexpensive monofilament suture with good tensile strength and minimal tissue reactivity. It is disadvantageous in terms of use and knot safety, but it is one of the most popular nonabsorbable suture in dermatological surgery. It is also known as subcutaneous suture. Surgilon and Nurolon sutures are better than others, but nylon suture prices are quite high.
- Polybutester (Novafil): It is a nonabsorable suture material of monofilament suture with excellent flexibility. It responds well to tissue edema and is also suitable for subcucular sutures.
- Polypropylene (Prolene, Surgilene): As a monofilament polymer with a very low coefficient of friction, polypropylene sutures make it the suture of choice for subcuticular sutures. It has good plasticity, limited flexibility, poor node security, and is relatively expensive. It is preferred as an aesthetic nonabsorbable suture and is used in areas such as facial repairs.
- Polyester (Mersylene Suture): It is a braided multifilament suture with high strength and low tissue reactivity. It has a low coefficient of friction value. Flexibility; polyester nonabsorbable suture is excellent for mucosal surfaces without the reactivity of silk.
