The polyester suture is a non-absorbable, braided, sterile, and surgical suture. It is prepared with fibers of high molecular weight, long-chain and linear polyesters, and recurrent aromatic rings as an integral component. The suture is uniformly coated with polybutilate. It is a highly adherent coating, and it is retrieved as a non-reactive, non-absorbable compound that acts as a lubricant so that it can improve the physical properties of an uncoated suture. However, it is improving handling qualities as a contrast to braided uncoated fiber. The characteristics of polyester suture is unsurpassed tensile strength and non absorbability. It is also resistant to repeated bending and synthetic and braided structure and coated with multifilament and hermetically sealed packing. The benefits of a polyester suture include excellent and permanent tissue support. The suture is used in cardiovascular surgery, while it has minimal tissue reaction, excellent handling properties, high flexibility, high tensile strength, and excellent knot security. It goes through a soft passage through the tissue with minimal sewing tissue, and it also has a guaranteed seal and product sterility. While the indication is general soft closing and igation in general surgery, skin closure, ophthalmic surgery, oral surgery, gastrointestinal surgery, etc. Available in various sizes and coatings, polyester sutures can meet the needs of different surgical procedures. The non-absorbable nature and chemical composition of polyester sutures reduce the risk of infection, a vital consideration in surgical outcomes. These sutures are resistant to acids, alkalis, and most of the common organic solvents, making them suitable for use in different physiological conditions without breaking down. Polyester sutures stand as a superior choice in the array of surgical suturing options due to their robust, flexible, and biocompatible nature. Their unique composition of high-molecular-weight polyesters, enhanced with a polybutilate coating, ensures both durability and ease of use. This combination not only minimizes tissue reaction but also maintains consistent tensile strength and flexibility, essential for the demanding environments of surgeries like cardiovascular and gastrointestinal procedures. As such, these sutures continue to be a preferred option in diverse surgical disciplines, reflecting their critical role in improving surgical outcomes and patient healing processes.
