Catgut
Plain gut is derived from bovine or sheep intestines, and therefore breaks down by enzymatic degradation, rather than the hydrolysis which breaks down synthetic absorbable sutures. Chromic gut is a longer-lasting version of gut, while fast-absorbing gut is heat treated to speed up absorption. On a practical level, fast-absorbing gut may be useful for closures when transepidermal sutures are desired for wound-edge apposition but where suture removal is impractical or inconvenient. Gut does lead to more tissue reactivity than other absorbable sutures and has a tendency toward breakage after multiple passes through tissue.
