The pressure on the wound constricts the blood vessels manually, helping to stem blood flow. When applying pressure, the type and direction of the wound may have an effect, for instance, a cut lengthways on the hand would be opened up by closing the hand into a fist, whilst a cut across the hand would be sealed by making a fist.
Other stitches or suturing techniques include: Purse-string suture, a continuous, circular inverting suture which is made to secure apposition of the edges of a surgical or traumatic wound. [13] [14] Figure-of-eight stitch; Subcuticular stitch. A continuous suture where the needle enters and exits the epidermis along the plane of the skin.
The corner stitch is a common suture technique. [1] It used to close wounds that are angled or Y-shaped without appreciably compromising blood supply to the wound tip. [2] [3] The corner stitch is a variation of the horizontal mattress stitch, and is sometimes called the "half-buried horizontal mattress stitch". [4]
Certainly modern synthetic sutures are more predictable and less prone to infection than catgut, silk and linen, which were the main suture materials used up to the 1990s. One key feature of intestinal staplers is that the edges of the stapler act as a haemostat , compressing the edges of the wound and closing blood vessels during the stapling ...
They tend to absorb this suture at a higher rate. Special precautions should be taken in elderly patients and patients with history of anemia and malnutrition conditions. As with any suture material, adequate knot security requires the accepted surgical technique of flat and square ties. The PDS suture knots must be properly placed to be secure.
Continuation of the 2 continuous sutures from each of their corners results in both sutures meeting at the middle anterior portion of the anastomosis. [6] The suture loops are then tightened and finished with at least 8 knots. [6] In both end-to-side and side-to-side CDD, the anastomosis should have a diameter of at least 14mm. [6]
New knots have been described. Other commonly employed knots are surgeon's knot, modified surgeon's knot, single-double other side knot, strangle knot and modified miller's knot. The Surgeon's knot has been a standard ligature but in one study it demonstrated slippage. [4] While the suture is being put in place a knot is used to secure the suture.
The European Hernia Society recommends that in cases where an open approach is indicated, the Lichtenstein technique be utilized as the preferred method. [12] Recent studies have indicated that mesh attachment with the use of adhesive glue is faster and less likely to cause post-op pain as compared to attachment via suture material. [44] [45] [46]
