Surgical Sutures  (stitches) are central to the art of surgery. The range of types available may appear confusing, generally, they are absorbable and non-absorbable and their structure may be divided into Monofilament, twisted or Braided. Examples of Absorbable Sutures are catgut, polydioxanone (PDS), Polyglactin (Vicryl), and Polyglycolic(Dexon). Non-Absorbable Suture include Silk,Nylon and Prolene. Monofilament Suture  are quite slippery but minimize infection but produce less reaction. Silk Black Braided  have plaited strands and provide secure knots, but they may allow infection to occur between their strands. Twisted Sutures have two twisted strands and similar qualities to Braided Sutures .

The time of Suture removal depends on the site and the general state of the patient. Face and neck Sutures tend to be removed after 5 days (may be earlier in children's). Scalp and back of neck after 5 days, and abdominal incisions after 5-10 days. In patients with poor wound healing, e.g. on steroids, with malignancy, infection, or cachexia, the sutures may need 14 days or longer.
