What did they use for stitches in the old days?
Greek surgeon Galen of Pergamon notes that he uses silk or catgut (made from the twisted intestines of sheep or horses) to suture together gladiators’ severed tendons. Similar materials are used for sutures well into the 20th century.
What do they use for dissolvable stitches?
A material that’s commonly used for dissolvable stitches in orthopedic surgeries, like knee surgery, is polydioxanone. These stitches can take about six months to completely dissolve.
What color are dissolvable stitches?
Generally absorbable sutures are clear or white in colour. They are often buried by threading the suture under the skin edges and are only visible as threads coming out of the ends of the wound.
Should I pull out dissolvable stitches?
There is generally no need to remove dissolvable stitches as they will eventually disappear on their own. If a person does need to remove their stitches, they should follow their doctor’s instructions carefully to reduce the risk of infection and other complications.
What happens if stitches don’t dissolve?
Occasionally, a stitch won’t dissolve completely. This usually occurs when part of the stitch is left on the outside of the body. There, the body’s fluids cannot dissolve and decompose the stitch, so it remains intact. A doctor can easily remove the remaining piece of stitch once the wound is closed.
What happens if a piece of stitch is left in the skin?
If the stitches are left in the skin for longer than is needed, they are more likely to leave a permanent scar. Nonabsorbable sutures also are ideal for internal wounds that need to heal for a prolonged time.

What is chromic catgut?
Chromic catgut is a modification of plain catgut that is tanned with chromic salts to improve strength and delay dissolution. 29. Gut is absorbed by phagocytosis, and is associated with a marked tissue inflammation that can be detrimental to healing.
