Stitches have been used in medicine for centuries, and the procedure hasn't changed much. Due to advances in sutures and suture alternatives, surgeons are able to close wounds faster and with less trauma to the patients. The type of material used is determined by factors such as the type of injury being repaired or procedure being done, healing time, and the patient's condition. It is important to be aware of the properties of each, so that you can have a meaningful discussion with your physician/surgeon.
