    1. Absorbable Suture
  2. Indications
    1. Use Vicryl or Dexon instead for Absorbable Suture
  3. Catgut (rarely used now)
    1. Derived from sheep intestinal intima
    2. Poor tensile strength
    3. Poor knot security
    4. Quickly absorbed within 4-5 days
    5. High tissue reactivity (absorbed by proteolysis)
  4. Chromic acid treated catgut (Mild Chromic Gut)
    1. Tensile strength longer than with cat gut
    2. Moderate tissue reactivity (absorbed by proteolysis)
    3. Poor knot security
