Chitin is an absorbable suture material with suitable mechanical properties. Tissue reaction is not specific and the good healing which ensued provided evidence for a satisfactory biocompatibility. Toxicity tests, including acute toxicity, pyrogenicity, mutagenicity were negative in all respects.

Chitin is considered as an absorbable surgical suture with great mechanical properties, biocompatibility, and biodegradability (Ciucă and Mihăilescu, 2015). There are different studies about the use of absorbable surgical sutures.
Today, most sutures are made of synthetic polymer fibers. Silk and, rarely, gut sutures are the only materials still in use from ancient times.
Overall, our results showed the potential use of cellulose fibers from vegetal for surgical sutures due to excellent mechanical properties, rapid degradation, and no bacterial adhesion.
Synthetic suture materials are made from a variety of polymers, including polyglycolic acid, polylactic acid, and polydioxanone. Monocryl™ is made from poliglecaprone 25 (a copolymer of glycolide and epsilon-caprolactone) and is manufactured by Ethicon®. Catgut suture is the original absorbable suture.
Chitin is a structural component of arthropod exoskeletons, fungi cell walls, mollusk shells, and fish scales. While humans don’t produce chitin, it has uses in medicine and as a nutritional supplement. It may be used to make biodegradable plastic and surgical thread, as a food additive, and in paper manufacturing.
Chitin is one of the most important biopolymers in nature. It is mainly produced by fungi, arthropods and nematodes. In insects, it functions as scaffold material, supporting the cuticles of the epidermis and trachea as well as the peritrophic matrices lining the gut epithelium.
PDO threads have been around the longest and are made of a synthetic biodegradable polymer that has been used in surgery for many years. PDO threads are absorbed into the body over 6 months by hydrolysis and work by triggering fibroblasts to produce more collagen in a targeted area.

What are sutures? Sutures, also known as stitches, are sterile surgical threads used to repair cuts. They are also commonly used to close incisions from surgery.
Some types of sutures are available with specialized coatings on the surface to enhance properties like knotting, easy passage through tissue and reduce tissue reaction.
An absorbable suture material (e.g., Dexon, Vicryl, PDS, Maxon, or Monocryl) can be used. One strand is used, without interruption, for the entire laceration.
Sutures (Stitches)
This is the most common technique for closing skin wounds. A doctor uses a piece of surgical thread called a suture to sew (or stitch) two ends of skin together. Surgeons once used animal tendons, horsehair, pieces of plants, or human hair to create sutures.
Absorbable suture material has the advantage of providing sufficient tensile strength for wound closure, while dissolving over time. This latter property minimizes the amount of foreign body material in a wound, thereby decreasing the risk of infection.
If you do sterilise sutures, the following should be considered. The two recommended methods are: Soak for a full 10 minutes completely immersed in povidone iodine 10% solution, then rinse in sterile saline/water. Ethylene Oxide – gas sterilisation.
Results: With the conventional surgical suture method (the addition of one throw on a surgeon’s knot), Surgilon proved to have the highest tensile strength (163.6 +/- 6.5 N). Other suture materials, when tied under the same conditions, slipped and did not reach the ultimate tensile strength.
