Catgut

The first synthetic polyglycoHc acid suture was introduced in 1970 with great success (21). This is because synthetic polymers are preferable to natural polymers since greater control over uniformity and mechanical properties are obtainable. The foreign body response to synthetic polymer absorption generally is quite predictable whereas catgut absorption is variable and usually produces a more intense inflammatory reaction (22). This greater tissue compatibihty is cmcial when the implant must serve as an inert, mechanical device prior to bioresorption.

Specific details of the sterility testing of parenteral products, ophthalmic and other non-injectable preparations, catgut, surgical dressings and dusting powders will be found in the British and European pharmacopoeias. 

In general, absorbent sutures are composed of materials that are natural to mammals, such as catgut, and to materials that are either quite susceptible to hydrolysis and/or polymers derived from natural materials such as polyglactin, which is a copolymer of lactic and glycolic acid. Nonabsorbent sutures can be made from natural materials such as cotton, which is a plant material, polymers that range from being hydrophobic to hydrophilic, and steel. 

Catgut sutures are seldom actually catgut. The name is derived from past practices. Today, so-called catgut is derived from the submucosa of sheep jejunum and the ileum or serosa of beef intestine that is cut into longitudinal ribbons. 

Both varieties of catgut are not employed for facial or surface use because of their tendency for scar formation and inflammatory response.

Catgut, which was used for medical suturing and as tough strings on tennis rackets and musical instruments, is not from cats, but comes from the intestines of sheep, horses, and other large mammals.
