Surgical Sutures: Classification, types, examples and uses

sutures can be classified into absorbable or non-absorbable materials. They can be further sub-classified into synthetic or natural sutures, and monofilament or multifilament sutures. The ideal suture is the smallest possible to produce uniform tensile strength, securely hold the wound for the required time for healing, then be absorbed. It should be predictable, easy to handle, produce minimal reaction, and knot securely. The suture type chosen vary much depends on the clinical scenario. For example, as a rough guide, a mass closure of a midline laparotomy may warrant use of PDS, a vascular anastomosis will probably require prolene, a hand-sewn bowel anastomosis may need vicryl, and securing a drain may need a silk suture. Absorbable vs Non-Absorbable Absorbable Sutures Absorbable sutures are broken down by the body via enzymatic reactions or hydrolysis. The time in which this absorption takes place varies between material, location of suture, and patient factors. Absorbable sutures are commonly used for deep tissues and tissues that heal rapidly; as a result, they may be used in small bowel anastomosis, suturing in the urinary or biliary tracts, or tying off small vessels near the skin. For the more commonly used absorbable sutures, complete absorption times will vary: Vicryl rapide = 42 days Vicryl = 60 days Monocryl = ~100 days PDS = ~200 days Non-Absorbable Sutures Non-absorbable sutures are used to provide long-term tissue support, remaining walled-off by the body’s inflammatory processes (until removed manually if required). Uses include for tissues that heal slowly, such as fascia or tendons, closure of abdominal wall, or vascular anastomoses.
